What to Do When a Client Won’t Pay Your Invoice
The job’s done, the invoice went out 47 days ago, and the client has stopped answering. Here’s the exact order of moves — nudge, call, letter, final demand — and how to choose between a lien, small claims court, and collections when the emails stop working.
First, rule out the boring explanations
Most unpaid invoices aren’t defiance — they’re disorganization. The invoice landed in spam. It’s missing the PO number their accounting software demands. Or your client is waiting on their client. One two-minute message rules that out: “Wanted to make sure invoice #214 reached the right inbox — can you confirm everything looks correct?”
The escalation ladder, with dates
- Days 1–3 overdue: friendly reminder. Short, warm, invoice attached, payment link included. Copy-paste versions here: invoice reminder email templates.
- Day 14: phone call. Email is easy to ignore; a voice isn’t. “Hi Dana — calling about invoice 214 for $1,850, due on the 1st. When can I expect payment?” Then stop talking. Get a date and confirm it by email the same hour.
- Day 30: firm letter, late fee applied. If your contract allows a late fee (1.5%/month is the common clause), apply it now and say so in writing — template here: late fee letter to a customer.
- Day 45: final demand letter. The last step before third parties get involved — and the letter that gets more invoices paid than any other.
Despite my reminders on July 3, July 17, and August 1, invoice #214 remains unpaid. The work was completed and signed off on June 28.
If payment is not received by [date 10 business days out], I will pursue collection through small claims court or a collections agency, which may add court costs and interest to the amount owed. I’d prefer to resolve this directly — pay at the link below or call me to arrange a payment plan.

The deadline and the named consequence make it work: vague “further action” reads as bluff; a date and a venue read as a plan.
If the demand letter fails: pick one lane
- Payment plan. If they’re broke rather than hostile, half now plus two scheduled payments beats 100% of nothing. Put the schedule in writing before you accept dollar one.
- Mechanics lien (trades only). If the work improved real property, a lien clouds the title until you’re paid. Deadlines are short — commonly 60–90 days after you finish — and some states require a preliminary notice before the job starts. Filing services run $95–$400; check your state’s rules the week the invoice goes late, not day 80.
- Small claims court. No lawyer needed, filing fees typically $30–$100, and most state limits fall between $5,000 and $15,000. A judgment doesn’t collect itself, but it unlocks wage garnishment and bank levies.
- Collections agency. They keep 25–50% of what they recover and the relationship is over the day you sign. Right answer for a client you never want back and an amount too small to sue over.
And know when to walk. If chasing a $300 invoice will eat six hours you bill at $85, write it off as bad debt and spend those hours on paying customers — with tighter terms next time.
Make this the last time
- Deposit before work starts. 30–50% up front filters out the clients who were never going to pay. Scripts here: how to ask for a deposit politely.
- Shorter terms. Due-on-receipt or Net 15 — here’s why Net 30 is usually a mistake for small service businesses.
- Late fee clause on every invoice and contract, so day 30 is automatic instead of awkward.
- Automated reminders, so the day-3 and day-14 nudges go out even when you’re on a roof.
- A stop-work trigger: any invoice 15 days past due pauses new work for that client. Announced up front, it’s policy, not punishment.
FAQ
Can I charge a late fee if it wasn’t in the contract?
It’s hard to enforce a fee the client never agreed to. Apply it only where your terms state it, and add a 1.5%/month clause to everything you send going forward.
How long should I wait before small claims court?
Once the final demand deadline passes — typically 60–75 days overdue — there’s little reason to wait. Statutes of limitations give you years, but memories, paper trails, and the client’s bank balance all get worse with time.
Is it worth suing over $500?
Often, yes: $30–$100 to file plus a morning in court, and many defendants pay as soon as they’re served. Below about $200, the math rarely works — write it off and fix your deposit policy instead.
What proof do I need?
The signed estimate or contract, the invoice, photos of the finished work, and every dated reminder. Your email trail is your court file.
