Can You Send a Business to Collections Without a Signed Contract?

Can I send someone to collections without a contract? For a business-to-business account, usually yes. A signed contract makes the claim stronger, but it is not the only proof that a debt exists. Invoices, purchase orders, delivery records, emails and partial payments can also establish what was ordered, what was delivered and what is owed.

Why “no contract” is rarely the real problem

Many small and mid-size businesses never sign a formal agreement. They quote a price by email, receive a purchase order, deliver the work and send an invoice. When the customer stops paying, the owner assumes nothing can be done without a signed document.

In practice, a business debt is shown by the whole transaction. If a customer asked for goods or services, received them, and was billed on stated terms, the record of that exchange is what matters. A collection agency looks at that record and asks a simple question: could the customer reasonably say it never agreed to this? The stronger the answer is “no,” the better the account will place.

The evidence that establishes a business debt

• Invoices and statements showing what was sold, when, for how much, and on what payment terms.
• Quotes, estimates and proposals that the customer accepted, including by email reply.
• Purchase orders and email approvals from someone with authority to order.
• Delivery receipts, job tickets and sign-offs signed or acknowledged by the customer.
• Partial payments and a course of dealing. Paying some invoices on the same terms suggests those terms were accepted.
• Written acknowledgments, including emails promising to pay, asking for more time or requesting a payment plan.
• Credit applications and account-opening forms, even if they are not a full contract.

No single item is magic. A file with three or four of these usually reads as a real account. A file with only an unsigned invoice and a verbal order is thin and needs work before it goes anywhere.

Rank your file: strong, workable or thin

Strong

Signed credit application or terms, purchase order, proof of delivery, invoices, and at least one written acknowledgment or partial payment. These accounts can be placed immediately.

Workable

No signed agreement, but there is a purchase order or approval email, a delivery record and clear invoices. Gaps are usually fixable with one confirming email from the customer.

Thin

Verbal order only, no proof of delivery, an invoice that differs from the quote, or a customer name you cannot verify. Fix what you can before placing, or talk to an attorney about whether a claim is realistic.

Weak spots to fix before you place the account

• Unclear scope or pricing, especially when the invoice differs from the quote.
• Verbal-only change orders that never made it into writing.
• Missing entity information: the exact legal name of the customer, its address and the person who ordered.
• No proof of delivery or completion.
• Invoices sent to an address or inbox the customer says it never used.

If you can close a gap, close it first. A short confirmation email from the customer that the work was received and the balance is owed is often enough to turn a weak file into a workable one. Keep the message simple and neutral: “Please confirm you received [goods or services] on [date] and that invoice [number] for [amount] is outstanding.” Replies, even partial ones, become part of the file.

What to send a collection agency

Whether or not you have a contract, an organized file shortens the first conversation with the customer and speeds recovery. Send:

1. Invoices and statements, in date order.
2. Any contract, credit application, quote or terms of sale.
3. Purchase orders and approval emails.
4. Proof of delivery or completion.
5. Payment history, including partial payments and returned payments.
6. Your log of calls and emails with the customer.
7. The customer’s legal name, address, contact names and phone numbers.

Consumer accounts work differently

If the customer is an individual and the debt is personal, the FDCPA and Regulation F apply to a third-party collector, including validation notice rules. Business accounts fall outside the FDCPA’s definition of debt and follow state law and contract principles. The Texas Debt Collection Act (Finance Code Chapter 392) is also limited to consumer debts, so a collector should know which kind of account it is working. If you are unsure which category an account falls into, say so when you place it. The answer changes how the collector may communicate.

Time limits still matter

A missing contract does not stop the clock. In Texas, a suit on a debt generally has to be filed within four years (Civil Practice and Remedies Code § 16.004(a)(3)), counted from when the claim accrued. For an open account between merchants, the four years run from the day the dealings cease (§ 16.004(c)). Other states have different periods and different rules for written and oral agreements. A thin file gets weaker with time, because memories fade and records disappear. If the account matters, act while the people involved are still reachable.

Preventing the problem next time

• Use a short credit application that includes terms acceptance, the customer’s legal name and a person authorized to order.
• Put your payment terms and late-fee language on every invoice and quote.
• Get a personal guarantee when the customer is a thinly capitalized entity and the credit line is large.
• Confirm change orders in writing, even if it is one line in an email.
• Get a signed delivery receipt or completion sign-off every time.
• Keep copies of everything in one place, organized by customer.

None of this requires a lawyer or a long agreement. It requires a habit. The accounts that collect easily are almost always the ones where someone took five minutes at the start to get the order, the terms and the delivery on paper.

Frequently asked questions

Can I send someone to collections without a contract?

For business accounts, generally yes. A signed contract makes a claim stronger but is not the only proof of a debt. Invoices, purchase orders, emails approving the work, delivery records and partial payments can all support it.

What documents does a collection agency need from me?

The invoices and statements, any contract or terms, purchase orders or approval emails, proof of delivery, a payment history and your contact log with the customer.

What if the customer says there was never an agreement?

Point to the transaction record: the order, the delivery, the invoices and any payments. A customer who accepted goods or services and paid part of the bill has a hard time arguing there was no agreement. Disputes about price or scope should be documented and resolved.

Does an unsigned invoice count as proof of a debt?

An invoice alone is weak. An invoice supported by an order, delivery record and any acknowledgment from the customer is much stronger. Gather the supporting items before placing the account.

Is the process different for a consumer debt?

Yes. Consumer debts are covered by the FDCPA and Regulation F when a third-party collector is involved, including validation and contact rules. Business debts are not covered by the FDCPA.

How long do I have to collect an unpaid business invoice?

It depends on the state and the type of claim. In Texas, a suit on a debt generally has to be filed within four years of when the claim accrued. Do not wait to find out; older accounts are harder to collect.

Should I talk to an attorney instead of an agency?

For large balances, active contract disputes or accounts where a lawsuit is the realistic next step, an attorney is often the right call. For undisputed past-due invoices, many creditors start with a commercial collection agency.
