What to Do When a Client Doesn't Pay Your Invoice


Every freelancer eventually deals with a client who doesn’t pay. Sometimes it’s an oversight. Sometimes it’s a cash flow problem on their end. Sometimes it’s intentional avoidance.

The approach that works best depends on where you are in the process. Here’s how to handle it at every stage.

Step 1: Send a Polite Reminder (Day After Due Date)

Most overdue invoices are genuinely forgotten. Accounting departments get busy, invoices slip through spam filters, and approval processes have delays.

Send a short, friendly email the business day after the due date:

Subject: Invoice #INV-042 — Friendly Reminder

Hi [Name],

Just following up on Invoice #INV-042 for $2,300, due June 2nd. Let me know if you need me to resend it or if you have any questions. Happy to help make this easy to process.

Thanks, [Your name]

Attach the original invoice again. No accusation, no ultimatum — just a clear, friendly nudge.

Step 2: Follow Up More Directly (7–10 Days Overdue)

If you haven’t heard back in a week, try again with a bit more directness:

Hi [Name],

I wanted to check in again on Invoice #INV-042 for $2,300, now 8 days past due. Could you let me know the status? I’m happy to set up a call if there’s any issue.

Best, [Your name]

At this point it’s also worth calling or messaging them on whatever channel you normally use — sometimes email isn’t enough.

Step 3: Escalate Internally (15+ Days Overdue)

If your main contact isn’t responding, try reaching someone else: their manager, the business owner, or the accounts payable department directly. Be professional, not accusatory — you’re looking for the right person to resolve this, not to create conflict.

Subject: Regarding Outstanding Invoice #INV-042

Hi [Manager’s Name],

I’ve been working with [contact name] on [project] and have an outstanding invoice of $2,300 that’s now 15 days past due. I’ve reached out a couple of times without response. I wanted to flag this with you in case there’s been a miscommunication or routing issue.

Invoice is attached. Please let me know how I can help get this resolved.

Thank you, [Your name]

Step 4: Send a Formal Demand Letter (30+ Days Overdue)

After 30 days of no payment and no response, it’s time for a formal written demand. This documents your attempts to collect and is typically required before legal action.

Your demand letter should:

  • State the amount owed and the original due date
  • Reference your contract or agreement
  • Specify a final deadline for payment (typically 7–14 days)
  • State consequences for non-payment (collections, small claims, legal action)
  • Be sent via certified mail or email with read receipt

You can write this yourself or have an attorney draft it. An attorney’s letterhead often produces fast results.

Step 5: Apply Late Fees

If your contract or invoice stated late payment terms, now is the time to apply them. Update the invoice to reflect the accumulated late fee and send a revised version.

Late fees serve two purposes: they compensate you for the delay and they create a financial incentive to pay now rather than later.

Step 6: Consider Collections or Small Claims Court

Small claims court is a viable option for invoices typically under $5,000–$10,000 (limits vary by state). Filing fees are low, you don’t need an attorney, and a judgment in your favor can be enforced against the client’s bank account or assets. The process is slower (months, not weeks) but can result in full recovery.

Collections agencies take a percentage of what they recover (often 25–40%) but require no upfront cost. For larger invoices or clients who’ve gone completely dark, a collections agency may be your most practical option.

Attorney demand and civil suit is the right path for large invoices where the amount justifies legal fees. An attorney can advise you on your best options in your state.

Protecting Yourself in the Future

Get a contract. Every project, every time. Your contract should specify the scope of work, payment amount, due dates, late fee terms, and what happens if either party doesn’t fulfill their obligations.

Require a deposit. A 25–50% upfront deposit is standard practice for projects over a certain size. It qualifies the client, covers your costs if they walk away, and means you’re never entirely at risk.

Invoice promptly. The longer after project completion, the harder it is to collect.

Check new clients. For large engagements with a new client, asking for references or running a quick background check is reasonable.

Set late fee terms upfront. Include late payment terms in your contract and on every invoice. Clients who see these terms don’t feel ambushed when you enforce them.

Tax Treatment of Unpaid Invoices

If a client truly won’t pay and you’ve exhausted your options, the unpaid invoice may be deductible as a bad debt. However, cash-basis taxpayers (most freelancers) generally cannot deduct bad debts because income is only recognized when received — you never actually counted that money as income, so there’s nothing to deduct. Accrual-basis businesses handle this differently.

Consult a CPA if you have a significant uncollectable invoice. The rules here are nuanced.
