The invoice is 137 days old. You have sent it four times. The controller who used to answer lets it go to voicemail now, and the last email said the check was “in this week’s run” — three weeks ago. Your own payroll does not reschedule itself.
Somebody has mentioned a Texas shortcut — a suit on sworn account, where your invoices become the evidence. It is real, and it is Texas Rule of Civil Procedure 185.
Here is the part almost nobody tells creditors: the shortcut has an off switch, and the debtor holds it. A properly verified account is prima facie evidence of your claim — until the defendant files a written denial under oath. That one filing collapses the case into ordinary contract litigation, where you prove sale, delivery, price, and nonpayment the hard way. So the question before you spend money is not does my account qualify. It is which kind of defendant do I have.
What Rule 185 actually is
It is not a cause of action the way breach of contract is. The Texas Supreme Court put it plainly: Rule 185 “is not a rule of substantive law but is a rule of procedure with regard to evidence necessary to establish a prima facie right of recovery.” Rizk v. Financial Guardian Insurance Agency, Inc., 584 S.W.2d 860, 862 (Tex. 1979). The claim stays contractual; the rule changes only what you must put on.
It reaches an action “founded upon an open account or other claim for goods, wares and merchandise, including any claim for a liquidated money demand based upon written contract or founded on business dealings between the parties, or is for personal service rendered, or labor done or labor or materials furnished, on which a systematic record has been kept.” If that fits your billing and the claim carries the right affidavit, the account “shall be taken as prima facie evidence thereof.”
Does your paperwork qualify?
Goods sold, services performed, labor done, materials furnished: the fact pattern behind most unpaid commercial invoices. Two filters decide it.
The transaction. Texas courts read the goods branch to require a genuine sale — “a sale upon one side and a purchase upon the other, whereby title to personal property passes from one to the other,” by general course of dealing rather than a special contract. That is why a credit-card balance is not a sworn account: no title passes from the bank to the cardholder. Tully v. Citibank (South Dakota), N.A., 173 S.W.3d 212 (Tex. App.—Texarkana 2005) (quoting Bird v. First Deposit National Bank, 994 S.W.2d 280, 282 (Tex. App.—El Paso 1999, pet. denied)). Much of the reported law here involves consumer debt buyers stretching a rule written for people who ship and perform work.
The record. Rule 185 requires a claim “on which a systematic record has been kept,” and says no particularization of the component parts is necessary unless the trial court sustains special exceptions — a warning, not a comfort. The working test is practical: can you produce, from your own system, a dated record of what was sold or performed, at what price, with payments and credits applied in order?
| Usually within Rule 185 | Usually outside it |
|---|---|
| Supplier invoices on a running account | Consumer credit-card balances |
| Service, labor, or materials billings on a systematic ledger | Claims resting on a special contract, or damages that are not a liquidated money demand |
Know the elements anyway: (1) a sale and delivery of the merchandise or performance of the services; (2) that the amount is just — the prices charged in accordance with an agreement, or absent an agreement the usual, customary, and reasonable prices; and (3) that the amount is unpaid. Day Cruises Maritime, L.L.C. v. Christus Spohn Health System, 267 S.W.3d 42, 53 (Tex. App.—Corpus Christi 2008, pet. denied). Rule 185 changes who proves them, and when.
The affidavit is where creditors lose
Rule 185 requires an affidavit of the party, its agent, or its attorney, taken before an officer authorized to administer oaths, to the effect that the claim is, within the knowledge of the affiant, just and true, that it is due, and that all just and lawful offsets, payments and credits have been allowed. If there is a deficiency in the sworn account, it does not carry prima facie effect at all. Enernational Corp. v. Exploitation Engineers, Inc., 705 S.W.2d 749, 750 (Tex. App.—Houston [1st Dist.] 1986, writ ref’d n.r.e.).
Three failure points:
- Offsets and credits. The affidavit swears they have all been allowed. An unapplied credit memo or a disputed backcharge still sitting in AR makes that untrue, and the defendant will say so.
- Knowledge. The rule says “within the knowledge of affiant.” A signature from someone who never touched the file is an invitation.
- Form. Under Tex. Gov’t Code § 312.011(1), an affidavit is a statement in writing of a fact or facts signed by the party making it, sworn to before an officer authorized to administer oaths, and officially certified by that officer under seal. A notary block that certifies only the signing, without an oath that the stated facts are true, has been held not to be a verified denial. Brown Foundation Repair & Consulting, Inc. v. Friendly Chevrolet Co., 715 S.W.2d 115, 117–18 (Tex. App.—Dallas 1986, writ ref’d n.r.e.). The defect is just as fatal on your side of the caption.
The trapdoor: Rule 93(10)
Rule 93 requires that a pleading setting up “[a] denial of an account which is the foundation of the plaintiff’s action, and supported by affidavit” be verified by affidavit. That is the off switch. A verified denial in the form Rule 185 requires “destroys the evidentiary effect of the itemized account … and forces the plaintiff to put on proof of his claim.” Rizk, 584 S.W.2d at 862–63.
Three details before you file:
- A sworn general denial does not do it. The denial has to be directed at the account, not at the petition in the abstract. Huddleston v. Case Power & Equipment Co., 748 S.W.2d 102, 103 (Tex. App.—Dallas 1988, no writ).
- It belongs in the answer. Rule 45 defines pleadings in the district and county courts as the petition and the answer, and a sworn denial raised for the first time in a summary-judgment response does not satisfy Rule 185. Cooper v. Scott Irrigation Construction, Inc., 838 S.W.2d 743, 746 (Tex. App.—El Paso 1992, no writ).
- Do not count on the defendant spoiling it. Pleading affirmative defenses alongside the verified denial does not nullify it; the Supreme Court rejected that argument in Rizk. And under Rule 63 a defendant may amend up to seven days before trial, and later with leave.
The practical read: a represented, engaged defendant will almost always file the verified denial, and Rule 185 buys you little. One who is dodging, unrepresented, or out of money often will not — and then the rule does real work.
If they never answer
Rule 99 requires the citation to direct the defendant to answer by 10:00 a.m. on the Monday next after twenty days from service. Miss that, and under Rule 239 the plaintiff may take judgment by default — but only once the return of service has been on file with the clerk ten days, exclusive of the day of filing and the day of judgment (Rule 107(h)). Where the claim is liquidated and proved by an instrument in writing, Rule 241 has the court assess the damages.
Layer Rule 185 on top and it compounds. A defendant who did not timely file a written denial under oath “shall not be permitted to deny the claim, or any item therein” — as the Tyler court put it, the opponent “will not be permitted to dispute the receipt of services or the correctness of the charges.” Andrews v. East Texas Medical Center–Athens, 885 S.W.2d 264, 267 (Tex. App.—Tyler 1994, no writ). That is why sworn accounts lend themselves to summary judgment: the pleadings can be the basis for it. Enernational, 705 S.W.2d at 750.
The forum problem nobody mentions
Justice courts have original jurisdiction of civil matters where the amount in controversy is not more than $20,000, exclusive of interest (Tex. Gov’t Code § 27.031(a)(1)), and a small claims case there is governed by Rules 500–507 of Part V (Rule 500.1(a)). Rule 500.1(e) then says the other Rules of Civil Procedure and the Rules of Evidence “do not apply except: (1) when the judge hearing the case determines that a particular rule must be followed to ensure that the proceedings are fair to all parties; or (2) when otherwise specifically provided by law or these rules.”
Rule 185 is one of those other rules. On a balance small enough for justice court, the sworn-account machinery is not automatically yours — Rule 185 is a district and county court tool. Plan the forum before you plan the affidavit.
Deadlines and numbers worth writing down
| Item | Authority | Number |
|---|---|---|
| Suit on a debt | Tex. Civ. Prac. & Rem. Code § 16.004(a)(3) | 4 years |
| Suit on an open or stated account | § 16.004(c) | 4 years, accruing the day the dealings cease |
| Answer deadline | Tex. R. Civ. P. 99(b), (c) | 10:00 a.m. Monday next after 20 days from service |
| Return of service on file before default | Tex. R. Civ. P. 107(h) | 10 days |
| Attorney’s fees: presentment | Tex. Civ. Prac. & Rem. Code § 38.002 | 30 days after the claim is presented |
| Interest with no agreed rate | Tex. Fin. Code § 302.002 | 6% a year from the 30th day after the amount is due |
The accrual language in § 16.004(c) — “the day that the dealings in which the parties were interested together cease” — can run later than your oldest invoice date, so check the Texas limitations reference or the state-by-state deadlines rather than guessing.

What to do this week
- Pull the ledger, not the invoice. Print the account showing every charge, date, payment, and credit through today. If it does not fit in one document, you do not yet have a systematic record.
- Reconcile the offsets. Apply every credit memo and disputed backcharge before anyone signs. The affidavit swears they are already allowed.
- Present the claim in writing and date it. Section 38.002 requires presentment and a 30-day window before fees.
- Find out whether the debtor will fight. A defendant with counsel and a live dispute will file the verified denial; price that case as ordinary litigation. One who has gone quiet may not answer at all.
- Pick the forum on purpose. Below $20,000 the case can go to justice court — cheaper and faster, but Rule 185 does not apply there by default.
Step four is the one you cannot do from your desk, and it is the honest argument for working the account before you buy a lawsuit: pressure, contact, and asset information tell you which defendant you have. Alexander, Strauss & Associates works commercial accounts in that sequence and escalates to legal collections through licensed collection attorneys when the file warrants it; the fee is agreed before you place anything. More detail: how to collect a commercial debt in Texas and the unpaid invoices overview.
Whether Rule 185 helps turns on facts specific to your account and your debtor. Before you file, have a Texas litigator read the ledger and the affidavit. That half hour is the cheapest part of the case.
