How to Chase an Overdue Invoice
Chasing money is the worst part of running a trade business, and most of it is preventable. Here's how to set terms that get paid, escalate properly when they don't, and know when to stop.
Every tradie has one — the invoice that's sixty days out, the client who stops answering, the job you'd rather write off than think about. Chasing it feels like begging for money you've already earned, which is exactly why most people leave it too long. The good news is that most of the fix happens before the invoice is even sent. This guide covers the terms that prevent the problem, the escalation ladder when it happens anyway, and the point at which chasing costs more than the debt.

Most of the fix happens before you invoice
An overdue invoice is usually a symptom of something set up wrong weeks earlier. These are the levers that do the most work, and all of them are cheaper than chasing:
- Take a deposit. A client who has paid something is a different client from one who hasn't. On larger jobs, stage it — deposit, progress payment, balance.
- Put terms on the quote, not just the invoice. They agreed to the terms when they accepted the quote; the invoice is too late to introduce them.
- Make the terms short and specific. "7 days from invoice date" beats "on completion", which means nothing.
- Invoice the day the job finishes. Every day you wait is a day added to the front of their payment cycle, and a day closer to them forgetting the detail.
- Make paying easy. An invoice with a payment link gets paid faster than one asking for a bank transfer. Friction is the main reason small invoices sit.
- Get variations agreed in writing as they happen, so the final figure isn't a surprise.
The single biggest predictor of getting paid on time is how fast you invoiced. A same-day invoice for work the client is still pleased about is a very different conversation from one that arrives three weeks later, after the goodwill has faded.
The escalation ladder
When an invoice does go past due, work through it in order. Each step is firmer than the last, and skipping straight to the end damages relationships you'd rather keep.
- Day 1 overdue — the automated reminder. A polite, automatic email the day after due date. No emotion, no accusation. A large share of overdue invoices are simply forgotten, and this catches most of them.
- Day 7 — the second reminder. Reattach the invoice and restate the terms. Still friendly. Assume it's an oversight, because it usually still is.
- Day 14 — pick up the phone. This is the step people skip, and it's the one that works. A short call gets you either payment or the real reason — cash flow, a dispute, a lost invoice. All three are useful; silence isn't.
- Day 21 — put it in writing, firmly. A written notice stating the amount, the original due date, and what happens next. Reference your terms. Keep it factual and unemotional — this document may be read by someone else later.
- Day 30+ — formal notice. A letter of demand, which you can write yourself or have a lawyer or collection agency send. This is the last step before external action, and it resolves a good portion of remaining debts on its own.
- Beyond that — external action. Debt collection, small claims tribunal or your state's building disputes body, depending on the amount and the trade. Weigh the cost and the hours against what you're owed.
Making the phone call work
The day-14 call is the highest-value ten minutes in this whole process. A few things that make it go better:
- Have the facts in front of you — invoice number, date, amount, what the job was, what was agreed.
- Open with a question, not an accusation. "I'm just following up invoice 1042 — has it come through your end?" gives them a way to respond without defending themselves.
- Then be quiet. Let them answer. The reason they give tells you which problem you're actually solving.
- Ask for a date, not a promise. "When can I expect it?" and then confirm that date in writing afterwards.
- Offer a payment plan if the honest answer is cash flow. Something arriving weekly beats nothing arriving at all.
When it's a dispute, not a delay
Sometimes the invoice isn't forgotten — the client thinks it's wrong. That's a different problem and chasing harder makes it worse.
- Find out exactly what they're disputing. The amount, the scope, the quality, or a variation they don't remember agreeing to. Get it specific before you respond to anything.
- Go back to the documents. The accepted quote, the written variations, the job photos. This is why capturing them at the time matters — a dispute is won on records, not recollection.
- Separate the disputed part. If they're arguing about one line, ask them to pay the rest while you sort it out. Most reasonable clients will, and it stops a small disagreement holding a whole invoice.
- Decide what it's worth. Sometimes conceding a contested item is cheaper than three weeks of argument. Price your own time into that decision.
If your records won't settle a dispute, that's the finding — not the outcome. Photos on the job, variations agreed in writing and an accepted quote with clear exclusions are what make these conversations short.
Knowing when to stop
Not every debt is worth pursuing. Before escalating past a letter of demand, be honest about three things: the size of the debt, the hours you'll spend, and the likelihood they can actually pay. A small debt chased for months at your charge-out rate is a bigger loss than writing it off on day forty.
Whatever you decide, take the lesson: deposit next time, shorter terms, or a client you don't work for again.
ServiceYak sends the invoice the day the job finishes, chases it automatically when it goes past due, and lets the client pay online — so most of this ladder never has to start.
Frequently asked questions
How long should I wait before chasing an invoice?
Send an automated reminder the day after it falls due, a second at a week, and phone at two weeks. Waiting a month before making contact teaches the client your terms are optional, and makes the eventual conversation harder than it needed to be.
Can I charge interest on late payments?
Only if you set it out in your terms before the work started, and the client agreed to those terms. A late-payment charge that first appears on the overdue invoice isn't something you agreed — put it in your quote terms if you want it available.
Should I take a deposit on every job?
On anything with material cost or more than a day's labour, yes. A deposit covers your outlay, filters out clients who were never going to pay, and changes the dynamic — someone with money already committed is far more likely to settle the balance.
What if the client says the work was faulty?
Treat it as a dispute rather than a collection problem. Get specific about what they're unhappy with, go to your photos and the accepted quote, and ask them to pay the undisputed portion while you resolve the rest. Chasing harder on a genuine quality complaint makes it worse.
