    CASTILLO INFORMATION TECHNOLOGY SERVICES, LLC, Appellant
    V.
    DYONYX, L.P., Appellee
    On Appeal from the 129th District Court
    Harris County, Texas
    Trial Court Case No. 2015-35885
    OPINION
    Appellant, Castillo Information Technology Services, LLC, sued appellee,
    Dyonyx, L.P., for breach of contract and promissory estoppel arising out of an
    agreement to provide telecommunications connectivity services.   Both parties
    moved for summary judgment, disputing whether the purchase order at issue was for
    a fixed five-year term or whether it could be terminated upon thirty days’ written
    notice, as the parties’ underlying consultant agreement provided. The trial court
    denied Castillo’s summary judgment motion, granted Dyonyx’s summary judgment
    motion, and dismissed Castillo’s claims with prejudice. In one issue, Castillo
    contends that the trial court erred in its summary judgment rulings because the
    purchase order under which Castillo provided its services did not incorporate the
    thirty-day termination provision contained within the consultant agreement.
    We affirm.
    Background
    Castillo and Dyonyx are both information technology consulting firms located
    in the Houston area. In July 2014, Dyonyx entered into a contract with the City of
    Houston to provide various telecommunications services, including the installation
    of internet circuits and connections between data centers located in Austin and Bryan
    as well as additional services including system hosting and support.
    On July 18, 2014, Dyonyx and Castillo entered into a Consultant Agreement,
    in which Dyonyx agreed “to retain the services of [Castillo] to assist it in discharging
    its obligations to its clients and to perform such other services as it may require from
    time to time.” The Consultant Agreement provided that its term was post-dated to
    begin on July 8, 2014, and end on July 7, 2019, or five years later. The Consultant
    2
    Agreement provided that Dyonyx could terminate the agreement earlier in three
    situations: (1) Dyonyx could dismiss Castillo for “cause” upon written notice to
    Castillo; (2) Dyonyx could terminate the contract with or without cause upon thirty
    days’ written notice to Castillo; or (3) Dyonyx could terminate the contract
    immediately upon written notice from Dyonyx’s client, if Dyonyx’s client
    terminated its contract with Dyonyx.
    In the Consultant Agreement, Castillo agreed to “develop for the benefit of
    [Dyonyx] certain services on a project basis” during the contractual term. The
    Consultant Agreement provided: “The scope of each project or any other projects
    agreed upon by the parties shall be identified in a Purchase Order (“PO”) and
    Statement of Work (“SOW”).” Attached to the Consultant Agreement as Exhibit A
    was a “Statement of Work.” The Statement of Work provided that Dyonyx’s client
    was the City of Houston Public Works and Engineering Department, that the
    location of the assignment was Austin and Bryan, and that the services to be
    performed were telecommunications and connectivity services, with no labor
    required. The Statement of Work also provided that purchase orders would be issued
    on an annual basis, with the “base period” running from July 8, 2014, through July
    7, 2015, and with “option periods” for each of the next four years, with the final
    option period ending July 7, 2019. The Statement of Work listed the “Firm Fixed
    3
    Price (Ceiling)” as $457,936.20, to be invoiced monthly in an amount of $7,632.27
    over a sixty-month period.
    On the same day the parties executed the Consultant Agreement, Dyonyx
    issued a Purchase Order to Castillo for a year’s worth of services under Dyonyx’s
    contract with the City of Houston, beginning July 8, 2014, and ending July 7, 2015.
    The Purchase Order stated the following under “Description of Item”:
    Firm Fixed Price – Annual Fee for Telecommunications/Connectivity
    Services for a 1.5GB Ethernet Burstable 1.5 Gig Ethernet Internet
    Circuit for the Data Foundry Data Center in Austin and Ethernet Line
    1 Gig connection between the Data Centers in Data Foundry (Austin)
    and Fibertown (Bryan) in support of the CoH Public Works and
    Engineering Dept. – Electronic Plan Review Project.
    This description was identical to a description of Castillo’s services to be provided
    to Dyonyx that was contained in the Statement of Work. The Purchase Order
    provided that a month’s worth of services1 cost $7,632.27, for a total of $91,587.24
    for the year. The Purchase Order stated, “Total amount of this purchase order sets
    forth the entire payment required.” Under “Justification,” the Purchase Order stated:
    Under the Terms and Conditions of the fully executed Consultant
    Agreement #00603 between DYONYX and [Castillo]. This is a Firm
    Fixed Price 5 year contract, but DYONYX will issue annual PO(s)
    1
    The summary judgment record included an affidavit from Talbot Theiss, Vice
    President of Strategic Accounts for Dyonyx, who averred that Castillo provided a
    “service, not a product” to Dyonyx. The Consultant Agreement and purchase order
    required Castillo to “provide data communication circuit services to [Dyonyx] on a
    monthly subscription basis. Those data communication services would then be used
    by [Dyonyx] to provide the City of Houston access to systems that were hosted by
    [Dyonyx].”
    4
    base[d] on the CoH PWE annual PO(s) issued against this project. This
    P.O. is not-to-exceed $91,587.24 for the period of performance stated
    above. There are no expenses required on this project.
    The Purchase Order was signed by representatives of both Dyonyx and Castillo.
    On November 7, 2014, four months after Dyonyx and Castillo entered into
    the Consultant Agreement and Dyonyx issued the Purchase Order to Castillo, the
    City of Houston informed Dyonyx that it was terminating the contract that it had
    with Dyonyx. The notice provided that, upon receipt, Dyonyx was to “discontinue
    all services in connection with” the performance of the contract and to cancel all
    existing purchase orders for services that Dyonyx had with vendors such as Castillo.
    On December 1, 2014, Dyonyx sent a written notice to Castillo informing it of the
    termination of the Purchase Order, effective December 31, 2014. In this notice,
    Dyonyx invoked the provision of the Consultant Agreement that allowed it to
    terminate the agreement with or without cause upon thirty days’ written notice to
    Castillo.
    Castillo subsequently sued Dyonyx for breach of contract and promissory
    estoppel. Castillo alleged that the Purchase Order issued by Dyonyx provided that
    the contract was a “Firm Fixed Price 5 year contract,” and as a result, Dyonyx could
    not rely upon the thirty-day termination provision in the Consultant Agreement to
    terminate the Purchase Order after only four months. Castillo further alleged that,
    in reliance upon the Purchase Order, it had “entered into firm, fixed-price 5-year
    5
    contracts as necessary with its suppliers in order to meet [its] commitments to
    Dyonyx under the purchase order.” Castillo alleged that Dyonyx had refused to
    make the monthly payments of $7,632.27 to Castillo after it terminated the contract,
    leaving a total of $427,407 owing to Castillo under the contract.
    Castillo moved for traditional summary judgment on its claims against
    Dyonyx. Castillo argued that the Purchase Order provided for twelve monthly
    payments of $7,632.27 to Castillo, but the Purchase Order also stated that it was a
    “Firm Fixed Price 5 year contract” and that Dyonyx would issue yearly purchase
    orders to Castillo pursuant to its contract with the City of Houston. Castillo argued
    that nothing in the Purchase Order provided that it could be terminated on thirty-
    days’ notice or that the Purchase Order was subject to the termination provisions
    contained in the Consultant Agreement. Castillo argued that, instead, the Purchase
    Order required Dyonyx to pay Castillo, regardless of whether the City of Houston
    terminated its contract with Dyonyx. In its summary judgment motion, Castillo also
    noted that although the third-party vendor it had retained to fulfill its contractual
    obligations had significantly discounted the invoice it submitted to Castillo after
    Dyonyx cancelled the Purchase Order, Castillo had still been required to pay its
    vendor $53,425.89, representing a full year’s worth of services. Castillo thus argued
    that the trial court should render summary judgment in its favor and award it
    6
    $53,425.89 in damages and $16,517.66 in attorney’s fees and costs, which it
    supported with an affidavit from its counsel.
    Dyonyx also moved for summary judgment, arguing that Castillo could not
    prove that Dyonyx breached the Consultant Agreement. Dyonyx argued that the
    Consultant Agreement and the Purchase Order were not independent contracts but
    instead “expressly incorporate, integrate, and reference the other.” The Consultant
    Agreement provided that Dyonyx would issue purchase orders to Castillo and that
    the scope of Castillo’s required services would be set out in a purchase order or
    statement of work. The Statement of Work attached to the Consultant Agreement
    provided that Dyonyx would issue purchase orders on an annual basis. Dyonyx
    argued that the Purchase Order that it issued expressly referenced the Consultant
    Agreement and stated that it was issued under the terms and conditions of that
    agreement. Dyonyx thus argued that “the proper termination of the Consultant
    Agreement terminates any purchase orders issued under that Consultant
    Agreement,” and it pointed out that the Consultant Agreement allowed it to
    terminate the contract upon thirty-days’ written notice and that it was undisputed
    that Dyonyx had provided thirty days’ written notice before terminating the contract.
    Dyonyx also argued that because the parties had entered into a valid contract—the
    Consultant Agreement—Castillo could not recover on its promissory estoppel claim.
    7
    The trial court denied Castillo’s motion for summary judgment and granted
    Dyonyx’s summary judgment motion, dismissing Castillo’s claims against Dyonyx
    with prejudice. Castillo filed a motion for new trial, which was overruled by
    operation of law. This appeal followed.
    Summary Judgment
    In its sole issue, Castillo contends that the trial court erroneously granted
    summary judgment in favor of Dyonyx and denied its own summary judgment
    motion. Specifically, Castillo contends that the Purchase Order did not incorporate
    the thirty-day termination provision contained within the Consultant Agreement;
    instead, the Purchase Order provided that the contract term was for five years, and
    Dyonyx breached the Purchase Order when it cancelled the Purchase Order after
    only four months.
    A.    Standard of Review
    We review a trial court’s ruling on a motion for summary judgment de novo.
    Mann Frankfort Stein & Lipp Advisors, Inc. v. Fielding, 
    289 S.W.3d 844
    , 848 (Tex.
    2009). When both parties move for summary judgment and the trial court grants one
    motion and denies the other, we review the summary judgment evidence submitted
    by both parties and determine all questions presented. 
    Id. We then
    render the
    judgment the trial court should have rendered. 
    Id. 8 A
    party moving for traditional summary judgment bears the burden of
    demonstrating that no genuine issues of material fact exist and that it is entitled to
    judgment as a matter of law. TEX. R. CIV. P. 166a(c); 
    Fielding, 289 S.W.3d at 848
    .
    When a plaintiff moves for summary judgment on its own claim, it must prove that
    it is entitled to judgment as a matter of law on each element of its cause of action.
    Cleveland v. Taylor, 
    397 S.W.3d 683
    , 696–97 (Tex. App.—Houston [1st Dist.]
    2012, pet. denied); G.C. Bldgs., Inc. v. RGS Contractors, Inc., 
    188 S.W.3d 739
    , 741–
    42 (Tex. App.—Dallas 2006, no pet.) (stating that if movant establishes right to
    judgment as matter of law, burden shifts to nonmovant to raise genuine issue of
    material fact or show movant’s legal position is unsound).
    B.    Interpretation of the Consultant Agreement and Purchase Order
    To prevail on a breach of contract claim, the plaintiff must establish (1) the
    existence of a valid contract; (2) performance or tendered performance by the
    plaintiff; (3) breach of the contract by the defendant; and (4) damages sustained by
    the plaintiff as a result of the breach. So. Elec. Servs., Inc. v. City of Houston, 
    355 S.W.3d 319
    , 323–24 (Tex. App.—Houston [1st Dist.] 2011, pet. denied).
    Contract language that can be given a certain or definite meaning is not
    ambiguous, and in that situation we construe the contract as a matter of law.
    Chrysler Ins. Co. v. Greenspoint Dodge of Houston, Inc., 
    297 S.W.3d 248
    , 252 (Tex.
    2009). In construing a written contract, our primary concern is to ascertain the true
    9
    intention of the parties as expressed in the contract. N. Shore Energy v. Harkins,
    
    501 S.W.3d 598
    , 602 (Tex. 2016) (per curiam); Plains Expl. & Prod. Co. v. Torch
    Energy Advisors Inc., 
    473 S.W.3d 296
    , 305 (Tex. 2015). “We ‘construe contracts
    from a utilitarian standpoint bearing in mind the particular business activity sought
    to be served,’ and avoiding unreasonable constructions when possible and proper.”
    Plains Expl. & 
    Prod., 473 S.W.3d at 305
    (quoting Reilly v. Rangers Mgmt., Inc., 
    727 S.W.2d 527
    , 530 (Tex. 1987)). We consider the entire writing, harmonizing and
    giving effect to all of the contract provisions so that none of them will be rendered
    meaningless. Id.; J.M. Davidson, Inc. v. Webster, 
    128 S.W.3d 223
    , 229 (Tex. 2003);
    see also Moayedi v. Interstate 35/Chisam Road, L.P., 
    438 S.W.3d 1
    , 7 (Tex. 2014)
    (“When parties disagree over the meaning of an unambiguous contract, we
    determine the parties’ intent by examining the entire agreement.”). “No single
    provision taken alone is given controlling effect; rather, each must be considered in
    the context of the instrument as a whole.” Plains Expl. & 
    Prod., 473 S.W.3d at 305
    .
    The Texas Supreme Court has held that “well-established law” provides that
    instruments pertaining to the same transaction may be read together to ascertain the
    parties’ intent, “even if the parties executed the instruments at different times and
    the instruments do not expressly refer to each other.” Fort Worth Indep. Sch. Dist.
    v. City of Fort Worth, 
    22 S.W.3d 831
    , 840 (Tex. 2000); Owen v. Hendricks, 
    433 S.W.2d 164
    , 166 (Tex. 1968) (“[S]everal instruments may be read together when it
    10
    appears from their terms that they necessarily relate to the same transaction.”); see
    also In re Prudential Ins. Co. of Am., 
    148 S.W.3d 124
    , 135 (Tex. 2004) (orig.
    proceeding) (“[A]greements executed at the same time, with the same purpose, and
    as part of the same transaction, are construed together.”). In appropriate instances,
    courts may construe all of the documents “as if they were part of a single, unified
    instrument.” Fort Worth Indep. Sch. 
    Dist., 22 S.W.3d at 840
    ; Gray & Co. Realtors,
    Inc. v. Atl. Hous. Found., Inc., 
    228 S.W.3d 431
    , 436 (Tex. App.—Dallas 2007, no
    pet.); see also Halliburton Co. v. KBR, Inc., 
    446 S.W.3d 551
    , 564 (Tex. App.—
    Houston [1st Dist.] 2014, no pet.) (noting, when construing master service
    agreement and tax sharing agreement together as one contract, that agreements were
    between same parties, were signed five days apart, and were “facets of the same
    transaction entered into for the unitary purpose of effectuating the corporate
    separation of KBR from Halliburton”).
    Here, the undisputed summary judgment evidence established that Dyonyx
    entered into a contract with the City of Houston to provide data circuits and
    connectivity services with respect to data centers in Austin and Bryan. To perform
    its contractual obligations with the City of Houston, Dyonyx then entered into the
    Consultant Agreement with Castillo. This Agreement stated that Dynoyx “deems it
    advisable to retain the services of [Castillo] to assist it in discharging its obligations
    to its clients and to perform such other services as it may require from time to time.”
    11
    The parties agreed that the contract term would begin on July 8, 2014, and would
    end on July 7, 2019, although the parties also agreed that Dyonyx could terminate
    the Consultant Agreement early for cause, with or without cause upon thirty days’
    written notice, or immediately if Dyonyx’s client terminated its contract with
    Dyonyx. The parties also agreed that, during the contract term, Castillo would
    “develop for the benefit of [Dyonyx] certain services on a project basis” and that
    “[t]he scope of each project or any other projects agreed upon by the parties shall be
    identified in a Purchase Order (“PO”) and Statement of Work (“SOW”).” The
    parties executed this Agreement on July 18, 2014.
    It is also undisputed that Exhibit A to the Consultant Agreement, entitled
    “Statement of Work,” set out specific information related to the parties’ contractual
    obligations. The Statement of Work identified Dyonyx’s client as the City of
    Houston Public Works and Engineering Department, provided that the assignment
    would be located in Austin and Bryan, described the services to be performed as
    “Telecommunications/Connectivity Services/No Labor,” and specifically stated that
    Castillo would be responsible for providing data circuits and an Ethernet connection
    between Austin and Bryan. The Statement of Work also provided that purchase
    orders “will be issued on an annual basis” and that the “base period” of the contract
    was from July 8, 2014, through July 7, 2015, with “option period[s]” for each of the
    next four years, through July 7, 2019. The Statement of Work further provided a
    12
    “Firm Fixed Price (Ceiling)” of $457,936.20, to be invoiced monthly in the amount
    of $7,632.27 over a sixty-month period.
    The same day that the parties entered into the Consultant Agreement, Dyonyx
    issued the Purchase Order to Castillo. The Purchase Order described the subject of
    the order as:
    Firm Fixed Price – Annual Fee for Telecommunications/Connectivity
    Services for a 1.5GB Ethernet Burstable 1.5 Gig Ethernet Internet
    Circuit for the Data Foundry Data Center in Austin, and Ethernet Line
    1 Gig connection between the Data Centers in Data Foundry (Austin)
    and Fibertown (Bryan) in support of the CoH Public Works and
    Engineering Dept. – Electronic Plan Review Project.
    The Purchase Order stated that the monthly cost of the services was $7,632.27, for
    a total cost of $91,587.24 for the year. The Purchase Order listed the “Period of
    Performance” as July 8, 2014, through July 7, 2015, and stated that the “[t]otal
    amount of this purchase order sets for the entire payment required.”            Under
    “Justification,” the Purchase Order provided:
    Under the Terms and Conditions of the fully executed Consultant
    Agreement #00603 between DYONYX and [Castillo]. This is a Firm
    Fixed Price 5 year contract, but Dyonyx will issue annual PO(s) base[d]
    on the CoH PWE annual PO(s) issued against this project. This P.O. is
    not-to-exceed $91,587.24 for the period of performance stated above.
    There are no expenses required on this project.
    Castillo’s president signed the Purchase Order on July 21, 2014.
    It is further undisputed that the City of Houston informed Dyonyx that it was
    terminating their contract in November 2014. Dyonyx then informed Castillo on
    13
    December 1, 2014, that, effective December 31, 2014, it was terminating the
    Consultant Agreement and the Purchase Order.
    In arguing that Dyonyx breached the parties’ contract, Castillo cites several
    cases for the proposition that the language in the “Justification” section of the
    Purchase Order—“Under the Terms and Conditions of the fully executed Consultant
    Agreement #00603 between DYONYX and [Castillo]”—was not sufficiently
    specific to incorporate the terms of the Consultant Agreement by reference into the
    Purchase Order, specifically, the provisions in the Consultant Agreement allowing
    Dyonyx to terminate the Agreement before the five-year term expired. See 
    Owens, 433 S.W.2d at 167
    ; Bob Montgomery Chevrolet, Inc. v. Dent Zone Co., 
    409 S.W.3d 181
    , 189 (Tex. App.—Dallas 2013, no pet.); In re C & H News Co.,

    14
    Each of these cases stands for the proposition that a signed contract may
    incorporate an unsigned document by reference, but to do so, the contract must refer
    to the unsigned document with sufficient specificity. See, e.g., Bob Montgomery
    
    Chevrolet, 409 S.W.3d at 189
    (holding that unsigned document may be incorporated
    by reference into signed contract by referring to unsigned document in contract, but
    “[p]lainly referring to a document requires more than merely mentioning the
    document”); Trico Marine 
    Servs., 73 S.W.3d at 549
    –50.
    In Owens, for example, the Texas Supreme Court addressed whether a letter
    written by a seller of real estate, but which did not contain enough information to
    sufficiently describe the land, incorporated by reference an earlier letter that did
    describe the land written by a real estate broker inquiring about the sale. 
    See 433 S.W.2d at 166
    . The court recognized that “[i]t is uniformly held that an unsigned
    paper may be incorporated by reference in the paper signed by the person sought to
    be charged” and further stated that “[t]he language used is not important provided
    the document signed by the defendant plainly refers to another writing.” 
    Id. The court
    noted that when the letter from the broker and the letter from the seller were
    read together, it appeared that the letter written by the seller was in reply to the earlier
    letter from the broker. 
    Id. at 167.
    The court stated, however, that although the two
    letters “obviously relate to the same subject matter,” there was nothing in the letter
    by the seller—the defendant and the party “sought to be charged”—“that even
    15
    remotely suggests the existence of another writing.” 
    Id. The court
    concluded that
    because the contents of the seller’s letter did not demonstrate that it was “based on
    an adoption of the letter written by [the broker],” the seller’s letter did not
    incorporate the broker’s letter by reference. 
    Id. In Bob
    Montgomery Chevrolet, the signed contract allowed an automobile
    dealership to become a “certified repair center” for a company that provided a dent
    repair 
    service. 409 S.W.3d at 184
    . The contract referred to a document on the
    company’s website that contained information about a special service program. 
    Id. at 185.
    This document, not signed by the dealership, also contained a forum
    selection clause. 
    Id. In subsequent
    litigation, the company sought to enforce the
    forum selection clause against the dealership, arguing that the signed contract, which
    mentioned the Internet document containing the forum selection clause, incorporated
    that document by reference. 
    Id. at 188–89.
    The Dallas Court of Appeals disagreed,
    reasoning that the contract language mentioning the website did not state that the
    document was incorporated by reference into the contract, did not “plainly refer to
    additional terms and conditions in the internet document as becoming part of the
    parties’ agreement,” and did not “otherwise suggest that the parties intended for the
    internet document to become part of their agreement.”

    Purchases/Sales,” incorporated unsigned “General Terms” document, which was
    available on Valero’s website, by reference for limited purpose of governing quoted
    prices but did not incorporate forum selection clause contained within “General
    Terms” document).
    Unlike the cases cited by Castillo, this case does not involve a party attempting
    to incorporate by reference an unsigned document into a signed contract. Instead,
    this case involves two documents—the Consultant Agreement and the Purchase
    17
    Order—both of which were signed by representatives of both Castillo and Dyonyx,
    and both of which reference each other and relate to the same transaction. We
    conclude that Owens and its progeny are inapposite.
    The Consultant Agreement, signed by both Castillo and Dyonyx, expressly
    contemplated the issuance of a purchase order that, along with a “Statement of
    Work,” would set out the scope of services that Castillo was to perform pursuant to
    the Agreement. The Purchase Order, issued and signed by Dyonyx on the same day
    the parties executed the Consultant Agreement and signed by Castillo three days
    later, stated that it was issued under the parties’ Consultant Agreement. The
    description of services in the Purchase Order mirrors the language of the Statement
    of Work attached to the Consultant Agreement.           These two documents were
    executed near the same time, the documents involve the same purpose, and the
    documents clearly pertain to the same transaction. We therefore must construe these
    documents together. See In re 
    Prudential, 148 S.W.3d at 145

    Castillo argues that we cannot construe the Purchase Order “to incorporate a
    30-day termination provision without rendering the terms ‘firm,’ ‘5-year-contract,’
    and ‘payment required’ meaningless.” However, focusing solely on the statement
    in the Purchase Order that “[t]his is a Firm Fixed Price 5 year contract” in isolation,
    as Castillo would have us do, would render meaningless the early termination
    18
    provisions in the Consultant Agreement, which must be read with the Purchase
    Order, as well as the provisions in the Statement of Work setting out the schedule of
    performance with a “base period” of one year followed by four one-year “option
    period[s].”
    The Consultant Agreement provided that it would be in effect for five years,
    beginning on July 8, 2014, and ending July 7, 2019, but it also designated three
    situations in which Dyonyx could terminate the Agreement earlier: (1) for cause;
    (2) with or without cause upon thirty days’ written notice; or (3) “[i]mmediately
    upon written notice from DYONYX’s Client, should the Client terminate its contract
    with DYONYX.” The Consultant Agreement also provided that throughout the
    contract term Castillo would provide services to Dynoyx, the scope of which would
    be set out in a purchase order and a Statement of Work. The Statement of Work,
    attached to the Consultant Agreement as Exhibit A, stated that Dyonyx would issue
    purchase orders on an annual basis and that the “base period” would be from July 8,
    2014, through July 7, 2015. The Statement of Work described each of the next four
    years after that, from July 8, 2015, through, ultimately, July 7, 2019, as “option
    period[s].” The Statement of Work also stated a price of $7,632.27 per month over
    a sixty-month period, for a total “ceiling” contract price of $457,936.20. Thus, the
    Statement of Work set the monthly price Dyonyx would pay for Castillo’s services,
    set out a maximum contract term of five years if each of the four “option period[s]”
    19
    was exercised, and stated the maximum amount Castillo would be paid if it
    ultimately provided services for the full five years.
    The Purchase Order, issued the same day as the Consultant Agreement and its
    attached Statement of Work, mirrored the Statement of Work’s description of the
    services Castillo was to provide and stated that the monthly cost of the services to
    be paid to Castillo was $7,632.27. The Purchase Order stated that the period of
    performance was from July 8, 2014, through July 7, 2015, or for one year, and
    provided that the “[t]otal amount of this purchase order,” or $91,587.24, “sets forth
    the entire payment required.” The Purchase Order also stated, “This is a Firm Fixed
    Price 5 year contract, but DYONYX will issue annual PO(s) [purchase orders]
    base[d] on the CoH PWE annual PO(s) [i]ssued against this project.” Thus, the
    Purchase Order stated that the parties had a five-year contract, consistent with the
    Consultant Agreement; it stated that the price for Castillo’s services was $7,632.27
    per month, consistent with the Statement of Work; and it stated that Dyonyx would
    issue purchase orders on an annual basis pursuant to purchase orders issued by its
    client, the City of Houston, also consistent with the Statement of Work.
    Reading these documents together, as we must, we conclude that the parties
    intended to enter into an agreement consisting of a Consultant Agreement, a
    Statement of Work, and a Purchase Order whereby Castillo would provide services
    to Dyonyx for a maximum of five years. See Plains Expl. & 
    Prod., 473 S.W.3d at 20
    305 (stating that when construing contract, we consider entire writing, harmonizing
    and giving effect to all contract provisions so that none will be rendered
    meaningless).   However, the parties agreed in the Consultant Agreement that
    Dyonyx could terminate that Agreement with or without cause upon thirty days’
    written notice or immediately if Dyonyx’s client, defined in the Statement of Work
    as the City of Houston, terminated its contract with Dyonyx. Thus, if Dyonyx
    properly terminated the Consultant Agreement pursuant to its terms, the Purchase
    Order issued pursuant to the Consultant Agreement also terminated without
    constituting a breach of the contract between the parties. See Fort Worth Indep. Sch.
    
    Dist., 22 S.W.3d at 840
    (holding that instruments pertaining to same transaction may
    be read together to ascertain parties’ intent and that courts may construe documents
    “as if they were part of a single, unified instrument”). Because it is undisputed that
    Dyonyx, after being informed by the City of Houston that the City was terminating
    its contract with Dyonyx, provided thirty days’ written notice to Castillo that the
    Consultant Agreement would terminate, we conclude that Dyonyx conclusively
    established that it did not breach its contract with Castillo. We therefore hold that
    the trial court did not err by granting Dyonyx’s summary judgment motion and
    denying Castillo’s motion.
    We overrule Castillo’s sole issue.
    21
    Conclusion
    We affirm the judgment of the trial court.
