When a customer does not pay
Most unpaid invoices are not disputes. They are drift.
The customer meant to pay, the email went into a pile, and now three weeks have passed and neither of you wants to mention it. Treating drift like a dispute is what turns it into one.
The sequence, for a normal small service invoice:
- Day 3 after due: short factual reminder. Amount, date, payment link. No accusation, no apology.
- Day 10: second reminder, slightly more direct, offering a way to resolve it. "Is there a problem with the invoice, or does a different payment method work better?"
- Day 21: a clear final message stating what happens next and by when.
Escalate in directness, never in volume. Three well-spaced messages collect more than nine anxious ones, and they leave the relationship intact if the answer turns out to be that they were in hospital.
Then set your stopping point in advance. For most single jobs, chasing past a month costs more in time and attention than the invoice is worth, and deciding that while annoyed produces the wrong answer.
The messages
First reminder, day 3. Assume nothing is wrong.
Hi [name], just a reminder that invoice #142 for $179 was due on the 3rd. You can pay here: [link]. Thanks.
That is all of it. No "I hate to ask." No explanation of your cash flow. The moment you apologise for invoicing, you have made the payment optional.
Second reminder, day 10. Give them a route out.
Hi [name], invoice #142 ($179) is still showing unpaid. Is there an issue with the invoice, or would a different payment method be easier? Happy to sort it either way.
This one collects more than the other two combined, because it converts an awkward silence into a question with an easy answer. Some people are not paying because the link failed, the card was declined, or they only pay by transfer.
Final message, day 21. Clear, factual, no threats you will not carry out.
Hi [name], invoice #142 ($179) is now three weeks overdue. If it is not settled by the 28th I will have to [the specific thing you will actually do]. I would much rather sort it out. [link]
Only state consequences you will genuinely carry out. A threat you do not follow through on teaches the customer that your deadlines are decorative, and they will tell other people about how you handled it.
Where to stop
Set the rule before you need it.
For a single job in the $100 to $400 range, the arithmetic is usually straightforward: an hour of your time chasing is an hour not earning, and the recovery rate on invoices past a month without contact is not high. Most solo operators are better off closing it, keeping the record, and declining that customer's next booking.
For larger sums, or a commercial customer who intends to keep using you, the calculation is different and formal routes exist. That is a decision worth taking on the numbers rather than on how annoyed you are on the day.
Keep the record either way. Dates, messages, what was agreed, photographs of the completed work. If it ever becomes formal, the person with the record wins the boring parts.
The three changes that stop it
1. Take a deposit. The single most effective one. It removes the total-loss case entirely: a customer who has paid something has a stake, and you are never in the position of having spent four hours for nothing. It also filters, quietly and early, for people who intend to pay. Deposits and no-shows.
2. Collect at completion, not later. The gap between finishing and invoicing is where the whole problem lives. You are standing there, the work is visibly done, they are happy. That is the moment with the highest payment rate you will ever have. Sending an invoice that evening is a different transaction with a much worse conversion.
3. Send it the same day, every time. An invoice that arrives four days later has already signalled that timing is flexible.
Everything else is downstream of those three.
The things that make it worse
Doing more work for someone who has not paid for the last job. Obvious written down, common in practice, because saying no to a booking feels expensive and is not.
Inventing a late fee after the fact. A late fee is only meaningful if it was agreed before the work and is permitted where you operate. Added afterwards, it converts a slow payer into an argument and gives them a reason to dispute the whole invoice.
Discussing it publicly. A social media post about a non-paying customer costs you future customers, not that one.
Letting it become the story of your week. The financial loss on one small invoice is usually smaller than what the rumination costs you.
What Rigsheet does about it
Deposits at booking through Stripe, so the no-show and the walk-away both stop being total losses. Invoices sent from the job, at completion, on the phone in your hand, with the payment link in them. Payment status visible per job rather than reconstructed from a bank feed. Before-and-after photographs attached to the job, which settles the "it was not done properly" version of non-payment before it starts.
Deposits and card payments are on every Rigsheet plan, including the $4 Starter tier, because a feature that prevents the most expensive failure in this business is not a feature to put behind an upgrade.

About Rigsheet
Rigsheet is a job app from Baker Ventures LLC for one-to-three-person mobile service businesses: mobile auto detailers and residential cleaners first. Scheduling with drive-time gaps, quotes with vehicle and home-size pricing, deposits, "on my way" texts, before and after photos, invoices, and automated review requests. Plans start at $4 a month, with unlimited jobs, customers, quotes and invoices on every tier and no per-user fees.
It exists because the alternatives charge a solo operator team prices. A one-van business is not a small version of a ten-truck business, and pricing built around seats and add-ons makes that mistake expensive. The pricing calculators and operator guides on this site are free and need no account.
Questions and answers
What should you do first when an invoice is not paid?
Send a short factual reminder without any accusation in it. Most unpaid invoices are drift rather than refusal, and a plain reminder with the amount, the date and a payment link resolves the majority of them without a conversation.
How many times should you chase an unpaid invoice?
Three contacts across roughly three weeks is a reasonable sequence for a small service invoice, escalating in directness rather than in volume. After that, chasing costs more than the money for most single jobs, and the decision becomes whether to pursue it formally or close it.
Should you take a deposit to prevent this?
A deposit is the single most effective change, because it removes the total-loss case. A customer who has paid something has a stake in the job, and you are never in the position of having spent four hours for nothing.
Can you charge a late fee?
Only if it was agreed before the work, stated in writing, and permitted where you operate. A late fee invented after the invoice is unpaid is not enforceable and it converts a slow payer into an argument.
When should you stop chasing?
When the time you are spending is worth more than the invoice, or when contact has clearly stopped. Set the threshold in advance for your business, because deciding it while annoyed produces the wrong answer in both directions.
How do you avoid this happening again?
Take a deposit, collect at completion rather than invoicing later, and send the invoice the same day. Nearly every unpaid invoice in a solo service business traces back to one of those three not happening.
