Almost nobody sets out to not pay you. That is worth remembering, because it changes what works.
The overwhelming majority of unpaid invoices are drift. The invoice arrived at a busy moment, it did not get paid that day, and then it moved down the pile until it was old enough to be awkward. By the time you are chasing it, the customer is embarrassed, and embarrassed people avoid the phone.
Your systems should be built for that person, not for the rare genuine deadbeat.
Prevention is most of it
Get paid on completion, wherever the work allows. The single most effective change most small operations can make. The moment you are standing there and the customer is happy is the easiest moment to be paid you will ever have. Every day after that is harder.
Take a deposit on anything substantial. It confirms the customer is real, it funds your materials, and it means a total loss is never the total.
Progress payments on longer work. A third up front, a third at a defined milestone, the balance on completion. This is standard on larger jobs for a good reason: it limits your exposure at every point rather than staking the whole job on the final payment.
Make paying easy. Every additional step loses some people. Card on file, a payment link, a QR code on the invoice. "Mail a check" costs you weeks against a customer who genuinely intended to pay.
Put the terms in writing before you start. Not on the invoice, which they read after the work. In the quote, which they read while deciding.
Terms people actually read
Keep it short enough that it gets read:
- When payment is due. "Due on completion" or "due within 14 days." Not "net 30" unless you mean it and your customers use that language.
- How to pay. List the methods.
- What happens if it is late. A specific number, stated calmly.
- Who is responsible. On commercial work, the entity and the person.
On late fees: a modest, clearly stated fee is normal and enforceable in most places, and its value is almost entirely as a deadline rather than as revenue. The sentence "there's a $25 late fee after fourteen days" moves invoices. Actually charging it is a decision you make case by case. What matters is that it was disclosed before the work.
The escalation ladder
Have one, use the same one every time, and start earlier than feels comfortable.
Day 1, on completion. Invoice immediately. An invoice that arrives a week later tells the customer the money is not important to you.
Day 3. A friendly confirmation that it arrived. Not a chase, a receipt check. "Just making sure the invoice came through, let me know if you need it in a different format." This one catches the ones that went to spam and it establishes contact early.
Day 14. The first real reminder. Short, warm, specific. Restate the amount, the work, and how to pay. Include the payment link again.
Day 30. A phone call, not a message. This is the step people skip and it is the one that works. Most drifted invoices resolve on a two-minute call, because the embarrassment that stops someone replying to an email does not survive a friendly voice asking if everything was alright with the job.
Day 45. A written notice that is unmistakably formal. State the amount, the date the work was completed, that previous reminders went unanswered, and what you intend to do next. Send it in a way you can prove.
Day 60 onward. Decide: write it off, send it to collections, or file in small claims. Do not leave it in limbo, which is the option that costs you the most attention over the longest period.
Two rules throughout. Stay unfailingly polite, because you may be wrong about what happened and because anger is what turns a slow payer into a hostile one. And keep everything, because if this goes anywhere the documentation is the case.
What small claims is actually like
For amounts under your state's limit, which is commonly somewhere between five and fifteen thousand dollars, small claims exists precisely for this. You do not need a lawyer, the filing fee is modest, and the process is designed for people representing themselves.
What it needs from you:
- The contract or written quote, showing what was agreed.
- Evidence the work was done. Photos, signatures, delivery records.
- The invoice, and every reminder you sent, with dates.
- The right name. Suing the wrong entity is the most common way these fail. If the customer is a company, you need the exact registered name.
What it costs you is a day, and possibly two. Which means the honest arithmetic is that for smaller amounts the time is worth more than the money, and it is frequently better to write it off and move on.
The thing worth knowing: a large share of these are resolved before the hearing. Being served concentrates minds, and many defendants settle rather than take a day off work themselves.
Deciding when to stop
Set a threshold in advance, while you are calm. Below some amount, you send the ladder and then you write it off and never think about it again.
Chasing a small unpaid invoice for six months costs more in attention than the invoice was worth, and the attention comes out of the work that pays. Writing it off is not losing. It is deciding where your time goes.
What is worth doing every time, regardless of amount, is noting the customer. The same names come back around (more on that in how to fire a customer).
The one that is not on the invoice list
There is a second kind of money you never collected, and it never appears in accounts receivable because it never became an invoice.
It is the calls you did not answer. Those people are not late payers, they are not in any ledger, and they are usually a larger number than your bad debt.
If you are going to spend a weekend fixing how money reaches you, it is worth looking at both ends: the invoices that were not paid, and the jobs that never existed because nobody picked up (more on that in what missed calls cost).
