Start with a simple, polite reminder. Many unpaid invoices aren’t the result of bad intentions. People get busy, emails get buried, and invoices slip through the cracks. A brief follow-up email referencing the invoice number, amount, and due date is often enough to get the payment moving. Send this within a few days of the due date passing.

If the email doesn’t get a response within a week, follow up by phone. A conversation reveals things email can’t. Maybe the client is unhappy with the work and hasn’t said anything. Maybe they’re dealing with a cash flow problem and need a payment plan. You can’t solve the issue without knowing what it is, and a phone call gets you there faster.

When the client acknowledges they owe you but can’t pay the full amount, offer a payment plan in writing. Two or three installments over 30 to 60 days is reasonable for most situations. Get the agreement documented with specific dates and amounts so there’s no confusion later.

If communication stops entirely, send a formal demand letter. State the amount owed, the original due date, and a deadline for payment. Mention that you’ll pursue further action if the balance isn’t resolved. Keep the tone professional. This letter sometimes gets attention when emails and calls didn’t.

Beyond that, your options are small claims court for amounts under the California limit of $12,500 for businesses, or turning the account over to a collections agency. Collections agencies typically take a percentage of what they recover, but getting 70% of something is better than 100% of nothing.

On the bookkeeping side, your aging receivables report is your best tool. This shows every open invoice organized by how long it’s been outstanding. Review it regularly so nothing slips past 30 days without action. The longer an invoice goes unpaid, the less likely you are to collect. An invoicing and payment tracking system that flags overdue balances automatically makes this much easier to stay on top of.

If you’ve exhausted your collection efforts and the client truly isn’t going to pay, write off the balance as bad debt in your books. In QuickBooks Online, you can create a credit memo or journal entry to clear the receivable. This keeps your accounts receivable accurate and reflects the loss properly on your financial statements.

The best way to deal with non-paying clients is to reduce the chances of it happening in the first place. Require deposits before starting work, especially on larger projects. Set clear payment terms on every invoice. Send invoices promptly and follow up before the due date, not after. The more structure you put around your billing process, the fewer collections problems you’ll face.
