This civil dispute concerns allegations of breach of contract and amounts purportedly owed on an open account. Appellant, David C. Flettrich, A Professional Engineering Corporation (“Flettrich Corp.”), seeks review of the trial court’s March 3, 2025 judgment, which denied its “Petition for Damages on Open Account and for Breach of Contract” (“Petition”). Appellee is Dudley DeBosier, A Professional Law Corporation (“Dudley DeBosier”). For the following reasons, we affirm the trial court’s judgment.

FACTUAL BACKGROUND AND PROCEDURAL HISTORY 2017 Activity: Carbon Monoxide Exposure Incident and Expert Contract In late 2017, Dudley DeBosier hired Flettrich Corp. as an expert on a carbon monoxide exposure claim brought by its clients, Michael and Velma Casey (the “Caseys”).1 The alleged exposure occurred in August of that same year at the apartment complex where the Caseys lived at that time in Bossier City, Louisiana.

The contract between Flettrich Corp. and Dudley DeBosier (“Expert Contract”) contained the following pertinent provisions:

1 Though Dudley DeBosier initially filed the Caseys’ petition for damages in state court

against B.H. Management and Great American, those defendants ultimately had the matter removed to federal court.

4. Payment Terms ....

[D.] [A]ny portion of an invoice for authorized services which exceeds the available monies in the retainer account shall be paid by Client upon receipt of invoice. . . . an invoice not paid within 10 (ten) days of receipt shall be considered overdue.

6. Duties of Client. The Client’s duties specifically include, but are not limited to:

B. To make all payments as specified in paragraphs 4 and 5 under the terms as specified in paragraphs 4 and 5.

....

D. To provide expert with copies of or access to all non-

privileged, arguably relevant documents, evidence, or other materials in the case/project.

....

M. To provide all stop work instructions to the Expert in writing.

N. To provide all time deadlines or cost-based or other restrictions to the Expert in writing. . . .

....

7. Duties of Expert. The Expert’s duties are:

....

B. To formulate with honesty and due care and truthfully express Expert’s opinion(s) in those areas (and only those areas) where Expert feels qualified to render an opinion and where Client has requested an opinion. Client agrees that Expert’s opinion(s) are not preordained, might be contrary to Client’s position, and are subject to modification as a result of new or additional information.

....

[E.] [T]o prepare a written report if Client requests one.

13. Disputes. Where a dispute over an amount invoiced occurs, the following applies:

A. The Client must notify the Expert in writing that the Client is disputing an invoice within 10 (ten) days of receipt of invoice.

....

C. The Client must produce any and all evidence substantiating any disputed amounts within 10 (ten) days of receipt of invoice.

15. Additional Provisions ....

B. Scope of Work. Client is requesting that the Expert provide the following expert services:

1) Perform evaluation of the water heating and the heating, ventilating and air conditioning (HVAC)

systems serving the specific apartment complex building in which carbon monoxide poisoning was an issue to determine compliance with building code regulations as well as the origin and flow of carbon monoxide in both the interior and the exterior of the apartment complex building, and render opinions in a written report.

The record establishes that Flettrich Corp. drafted the contract.2 December 2019 Activity: Reports David C. Flettrich (“Mr. Flettrich”), P.E., president of Flettrich Corp., visited the Caseys’ former apartment in August 2019; and Flettrich Corp. then issued a report on the conditions that Mr. Flettrich discovered that he deemed unsafe and “life safety concerns” in December 2019 (the “December 2019 Unsafe Conditions Report”). Mr. Flettrich contended his professional obligations compelled him to do so. Flettrich Corp. also issued its expert opinion in the Casey matter in December 2019 (the “December 2019 Expert Report”). Thereafter,

2 More particularly, this was a form contract from Seak, “a very large expert witness company,” but “over the years” Flettrich Corp. had “made slight modifications here and there.”

Flettrich Corp. billed Dudley DeBosier for both Reports (“December 2019 Invoices”).

January 2020 Activity: First Stop Work Instruction In response to Flettrich Corp.’s December 2019 Invoices, on January 3, 2020, Adam Savoie (“Mr. Savoie”), an attorney at Dudley DeBosier working on the Casey matter, emailed Mr. Flettrich and informed him that he found Flettrich Corp.’s billing to be “astounding.” Additionally, Mr. Savoie instructed: “[P]lease do not perform any additional work on this file until instructed otherwise by the firm” (“January 2020 Stop Work Instruction”). Dudley DeBosier ultimately paid the December 2019 Invoices.

May 2020 Activity: Forthcoming Deposition and Letter Thereafter, on May 15, 2020, Mr. Flettrich learned that opposing counsel in the Casey matter wished to depose him. Then, on May 28, 2020, Mr. Flettrich sent a letter to Dudley DeBosier (“May 2020 Letter”). In pertinent part, the letter stated:

1. In accordance with paragraph 6.D of our Expert . . . Contract . .

., please provide me with copies of or access to all non-

privileged, arguably relevant documents, evidence and other materials in the case/project that have not previously been provided to me. . . .

Please note that I do not need to be provided any of the 86 court documents listed in the attached docket report that I printed from the Pacer [sic3] website . . . because I have access to each document contained in the docket report through my Pacer [sic]

account.

....

3. In accordance with paragraph 6.C of our Expert Contract, I request that you replenish the retainer by issuing a retainer check in the amount of $9,600.00, which will provide for an additional 32.0 hours of my time. Although the exact amount of

3 PACER is the electronic records database for the federal courts. The Casey matter was in the federal court system.

the additional time that will be required of me is indeterminate, a retainer equal to the initial retainer amount of $3,600.00 that is specified in paragraph 4 of our Expert contract will provide for only 12.0 additional hours of my time and is clearly inadequate to compensate me (1) for the time I expended subsequent to December 21, 2019 (the last day that you were invoiced for my time), e.g., for the time I expended obtaining new information from the Office of the State Fire Marshal (“OSFM”) and the City of Bossier, for the time I expended reviewing the 86 court documents . . .. (see ATTACHMENT 1)

for the purpose of determining what existing non-privileged, arguably relevant documents, evidence and other materials in the case/project have not yet been provided to me, etc., and (2)
