For a small business, an unpaid invoice is not just an annoyance - it means you have already paid for materials, fuel and wages, and the money is not coming in. Late payments are one of the most common reasons small companies run into trouble, even when they have plenty of work. These ten tips help you get paid faster, without damaging the relationship with your clients.
In short
- Agree on payment terms before the work starts and write them into the quote.
- Take an advance for larger jobs and invoice immediately after completion.
- Make paying easy: clear invoice, IBAN, online payment.
- Use automatic, polite reminders instead of awkward phone calls.
1. Agree on payment terms in the quote
Payment terms should never be a surprise. Write them into the quote: due date, advance, how to pay. When the client signs the quote, they also accept the terms. Read more in our guide on how to write a quote that clients accept.
2. Take an advance for larger jobs
For jobs with expensive materials, an advance of 30-50% is normal in most trades. You do not finance the client's project, and a client who has paid an advance is committed. In AdBooks you enter the percentage, the amount and VAT are calculated, and the advance is deducted from the final invoice automatically.
3. Invoice immediately
Every day between completing the job and sending the invoice is a day added to your waiting time. Send the invoice the same day - ideally directly from the job site, on your phone.
4. Make the invoice impossible to misunderstand
A clear invoice gets paid faster. It should include the invoice number, due date, a clear description of the work, your IBAN and the payment reference. Invoices that raise questions wait in a pile until somebody has time to call you.
5. Shorter payment terms
30 days is a habit, not a law of nature. For private clients and small jobs, 7 or 14 days is reasonable. The shorter the term, the sooner you see the money.
6. Make paying easy
The fewer steps, the faster the payment. Send the invoice as a link the client opens on the phone, and offer online payment by card or PayPal next to bank transfer. Many clients pay immediately when it takes ten seconds.

7. Send automatic reminders
Nobody likes chasing money. Automatic reminders do it for you - politely and on time: one reminder before the due date and follow-ups after it. In AdBooks, reminders are sent in the language of the document, so foreign clients receive them in their own language.
8. Use progress billing on long projects
On jobs that last weeks or months, do not wait until the end. Invoice by stages - for example by percentage of completion - so money comes in while the work progresses.
9. Keep track of who owes what
You cannot collect what you do not see. Keep an overview of open, overdue and paid invoices, and check it every week. Ten minutes on Monday morning can bring in thousands.
10. Reward good payers
Clients who pay on time are worth gold. Thank them, give them priority when scheduling and occasionally a small discount on the next job. Loyal clients who pay well are the best foundation of a healthy business.
Frequently asked questions
What is a normal payment term?
For private clients 7-14 days is common, for business clients 14-30 days. What counts is that the term is agreed in advance and written on the quote and invoice.
When should I send the first reminder?
A friendly reminder a few days before the due date works well, followed by reminders a few days and then one to two weeks after it. Automatic reminders keep this consistent.
Can I charge late payment interest?
In the EU, the Late Payment Directive allows statutory interest for late payments between businesses. Rules for private clients differ by country - check with your accountant.
Do advance payments scare clients away?
Rarely, if they are explained clearly. Most clients understand that materials must be paid before work starts.
Conclusion
Getting paid fast is a system, not luck: clear terms in the quote, advances for larger jobs, invoices on the same day, easy payment and automatic reminders. Set it up once, and your cash flow will thank you every month.
