How to Collect a Debt From a Business That Won't Pay You

Start by Confirming the Debt and Gathering Your Records

Before you chase payment, build your file. A business that ignores invoices often pays quickly once it sees you are organized and serious. The goal is simple: be able to prove what was owed, why, and that it is overdue. Collect everything in one folder so you can attach it to a demand or hand it to a court later.

Pull together the documentation that establishes the debt:

• The contract, proposal, or signed work order showing agreed scope and price (an email approving a quote counts too).
• Every invoice you sent, with dates, amounts, and due dates.
• Proof of delivery or completion — signed delivery receipts, shipping confirmations, timesheets, deliverable files, or a sign-off email.
• All communications — emails, texts, and chat messages where the work or payment was discussed.
• A payment ledger noting any partial payments and the running balance.

While you do this, double-check your own numbers. Confirm the amount is correct, that you actually delivered, and that the due date has truly passed. If your contract mentions late fees or interest, note the exact terms — but do not invent a rate. Whether you can add interest or fees depends on your agreement and your state's rules, so verify before you claim it.

Find the Right Person and the Right Entity

Many B2B debts stall because the request never reaches someone who can pay. Identify the legal name of the business (an LLC, corporation, or sole proprietor) — not just the brand name. Then aim higher than the contact who has gone quiet.

• Ask for accounts payable or the owner directly, in writing.
• Look up the company in your state's business registry to confirm its legal name and status.
• Find the registered agent — the person or company officially designated to receive legal and formal notices. This is who you address a formal demand to, and who must be served if you later file suit.

Knowing the exact entity matters. If you sue or send a formal demand to the wrong name, it can slow you down or weaken your position.

Step One: Send a Friendly Written Reminder

Pick up the phone or send a short, polite email first. Many late payments are oversights, disputes over an invoice detail, or cash-flow timing. A calm reminder often resolves it and preserves the relationship. Keep it factual: reference the invoice number, the amount, the original due date, and a clear request to pay by a specific new date. Put it in writing even if you also call, so there is a record.

If you get silence or excuses, send one firmer follow-up that signals the matter is escalating — but stay professional. You want a paper trail that shows you gave reasonable chances to pay.

Step Two: Send a Formal Demand Letter

When reminders fail, a formal demand letter is the standard next step. It is a clear, businesslike notice that states the debt, demands payment by a deadline, and signals you are prepared to pursue other options if ignored. Demand letters work because they show you are serious and create a documented record — and because the cost and hassle of dealing with the next stage often makes paying the simpler choice for the other business.

A solid demand letter includes:

1. The names of both businesses and the date.
2. A short statement of the facts — what you provided and the agreement behind it.
3. The exact amount owed, plus any late fees or interest you are entitled to under your contract.
4. A clear demand to pay in full by a specific deadline.
5. How to pay, and a note that you will consider further options if payment is not received.

Keep the tone firm and factual, not threatening. Send it in a way you can prove was delivered, and keep a copy. This is exactly what PaidUp does — answer a few questions and it generates a professional demand letter for you to review, sign, and send.

Step Three: Escalate if You're Ignored

If the deadline passes with no payment or good-faith response, you still have options. Which makes sense depends on the size of the debt, the cost of pursuing it, and the rules where you and the debtor are located. Treat the list below as general possibilities to research, not legal advice.

• Small claims court. Designed for smaller disputes, it is faster and cheaper than regular court and often does not require a lawyer. Each state sets its own dollar limit and procedures, so check your local court's rules before filing.
• A collections agency. Agencies pursue the debt for you, usually taking a percentage of what they recover. Useful when you do not want to spend your own time chasing it.
• An attorney. For larger debts or complicated disputes, a lawyer can send a demand on letterhead, negotiate, or file suit. Many offer a low-cost initial consultation.
• A mechanic's or contractor's lien. In some industries — especially construction and trades — you may be able to place a lien against the property you worked on if you are unpaid. These have strict deadlines and notice requirements that vary widely by state, so confirm whether they apply to you and act quickly.

Before pursuing any of these, weigh whether the business can actually pay. Chasing a judgment against a company with no assets can cost more than you recover.

Practical Tips for Dealing With a Non-Paying Business

A few habits make collection faster and keep you protected:

• Stay professional in every message. Anything you write could end up in front of a judge.
• Keep one organized file with the contract, invoices, proof of delivery, and all communications, in date order.
• Set firm deadlines and follow through on each step you say you'll take.
• Offer a payment plan if the business is willing but short on cash — partial recovery beats none.
• Watch your time limits. There is a deadline (a statute of limitations) for legally pursuing a debt, and it varies by state and type of claim. Don't let an old invoice sit indefinitely — verify your window.

The pattern that works: confirm the debt, send a reminder, send a formal demand, then escalate. Most disputes settle well before court when you move through these steps in order and keep good records.
