Late payment is the default, not the exception, for many small businesses and freelancers. The good news: most of the delay is caused by things you can control â when you invoice, what the invoice says, who receives it, how easy it is to pay, and how consistently you follow up. Here are fifteen practical changes, grouped by when they happen.
Before the work starts
1. Agree payment terms in writing
Your invoice should confirm terms, not introduce them. Put the payment schedule, due dates and late-payment terms in your contract or quote and get it accepted before work starts. A simple email reply (âApproved â please go aheadâ) is far better than nothing.
2. Ask for a deposit
For new clients, custom work, or projects longer than a couple of weeks, request 25â50% upfront. A deposit filters out clients who were never going to pay promptly, and it means youâre never fully exposed. Invoice the deposit immediately on acceptance.
3. Shorten your payment terms
If youâve been using Net 30 out of habit, consider Net 14 or Net 7 for smaller clients. Many will pay within whatever window you give them â so give them a shorter one. See payment terms explained for options.
4. Find out how the client pays invoices
Ask at the start:
- Who processes invoices, and what email address should they go to?
- Do you need a PO number, supplier registration or tax form first?
- Which legal entity and address should invoices be addressed to?
- When are your payment runs?
Large organisations often pay only on specific days, only against a PO, and only to registered suppliers. Knowing that upfront prevents weeks of silent delay.
5. Break big projects into milestones
Instead of one large invoice at the end of a three-month project, bill at defined milestones (e.g. 30% / 40% / 30%). Smaller invoices get approved faster and keep cash flowing.
When you send the invoice
6. Invoice immediately
Payment terms start when the invoice is issued. Every day you wait to invoice is a day added to your payment time. Make invoicing part of delivering the work: âsend files â send invoiceâ.
7. Make the invoice impossible to query
Most âlateâ invoices are actually invoices waiting for someone to clarify something. Include:
- The clientâs correct legal name and billing address
- Their PO number or reference
- Specific line items â what, how many, at what rate
- Correct tax treatment and your tax number
- An explicit due date, not just âNet 30â
See what to include on an invoice for the complete list.
8. Put the due date and amount in the email subject
âInvoice INV-2026-0047 â âŹ1,850.00 â due 14 Novâ is far more actionable than âInvoice attachedâ. The person processing it can see everything without opening the PDF.
9. Send a PDF, to the right person
PDFs look professional, canât be edited by accident and display the same everywhere. Send to the accounts contact and your project contact, so both know itâs coming. The BillKit invoice generator creates a clean PDF in the browser in about a minute.
Making it easy to pay
10. Offer more than one way to pay
The fewer steps between âapprovedâ and âpaidâ, the better. Bank transfer details should be complete (account name, IBAN/account number, BIC/SWIFT or routing number). For smaller or consumer clients, adding a card or online payment link removes a big obstacle â weigh the processing fees against how much faster youâre paid.
11. Remove friction for international clients
Invoice in a currency the client can pay easily, provide international bank details, and agree who pays transfer fees. Our guide on invoicing in a foreign currency covers the details.
12. Consider an early-payment incentive â carefully
Discounts like â2% if paid within 10 daysâ can work with some clients, but theyâre expensive. A 2% discount for paying 20 days early is the equivalent of roughly 37% annual interest. Often a shorter term or a deposit achieves the same thing for free.
After you send it
13. Track every invoice
Keep a simple list: invoice number, client, amount, date sent, due date, paid date. Look at it weekly. If you donât know whatâs overdue, you canât chase it.
14. Follow up on a schedule
Send a friendly reminder a few days before the due date for new clients, a neutral one on the due date, and escalate politely from there. Pick up the phone at around 14 days overdue. Our late payment reminder templates give you wording for every stage, plus a phone script.
15. Enforce your terms consistently
If your contract says work pauses when invoices are 30 days overdue, pause the work. If youâre entitled to statutory late-payment interest (as in the UK and EU) and youâve decided to use it, apply it consistently. Clients learn quickly which suppliers they can pay last.
For repeat clients: retainers and recurring invoices
If you work with a client every month, move them to a retainer billed in advance â for example, invoiced on the 1st, due on the 7th, for that monthâs work. You get paid before you do the work, and both sides get predictable budgets. See recurring invoices and retainers.
A quick self-audit
Score yourself: how many of these do you do every time?
| Practice | Yes / No |
|---|---|
| Written agreement on terms before starting | |
| Deposit for new clients or big projects | |
| Invoice sent the day work is delivered | |
| Explicit due date on every invoice | |
| PO number / client reference included | |
| Invoice sent to the accounts contact | |
| At least two easy ways to pay | |
| Reminder schedule followed | |
| Overdue list reviewed weekly |
Fix the âNoâ answers starting from the top â the earliest steps prevent the most problems.
What doesnât work
- Waiting and hoping. Silence is the most common cause of a 60-day delay.
- Apologetic reminders. âSorry to bother youâŠâ signals that paying late is fine. Be friendly and direct instead.
- Threats you wonât carry out. They undermine your credibility for next time.
- Changing the invoice to âfixâ a payment problem. If something was wrong, issue a credit note and a corrected invoice.
Summary
Get agreement and a deposit before you start, invoice immediately with a clear, complete document, make paying easy, and follow up on a schedule. None of it requires special software â just consistency. When youâre ready, create your next invoice and put these steps into practice.
