Freelancer Invoice Payment Terms: Deposits, Late Fees

Ask the client which legal entity, supplier record and purchase order the invoice must match. A brand name or an enthusiastic project manager does not fill those boxes in a finance system.

Example: the purchase order is EUR 750, and an extra task would bring the invoice to EUR 900. Before you do the extra task, send the new scope and price, get written approval from the person who can approve it and an updated order if the client needs one. If the invoice is already issued, keep the original and ask which correction document the client and your local rules require.

For a defined project, a deposit or staged invoices keep the unpaid work small. Write each trigger in plain terms: on signature, on kickoff, after delivery of a named milestone, on approval of the monthly report or on a calendar date. State the invoice date and the due date, not “pay promptly”.

Example: EUR 600 for a named deliverable, invoiced after written acceptance, payable by bank transfer 14 calendar days after the invoice date, with the invoice number as the reference. An invoice dated 1 October is due on 15 October; write that date on the invoice.

Write any deposit refund rule, late fee or pause in work into the agreement both sides sign, and keep a clear reminder routine.

Write what the monthly fee buys: deliverables, hours or reserved availability, the service period, response times and what is excluded. Say whether unused hours expire or roll over, and how notice, cancellation and refunds work. Agree whether you bill in advance or in arrears.

An invoice does not collect itself. Stripe, for example, separates invoices charged automatically from invoices sent for the client to pay, and an automatic charge can still fail. Track each month’s invoice until the money arrives, and agree extra work before you do it: if the client asks for five hours beyond a ten-hour allowance, agree the price first.

Example: September has USD 200 outstanding and October’s fee is USD 1,000. A USD 1,000 payment with no reference could belong to either month. Ask the client how to allocate it; if USD 200 closes September, October has USD 800 paid and USD 200 open. Record both lines and do not count the same payment in two months.

Plan for the retainer ending. Example: essential costs of USD 1,400 a month and other income of USD 600 leave a USD 800 monthly gap, so two months of cover needs USD 1,600, kept apart from tax money.

The invoice currency says what the client owes; the payment route says how the money reaches you. Write the currency code and amount, whether tax is included, and full payment details for one route. If conversion happens, agree who carries the fee and the exchange-rate risk.

Write down what happens if less arrives than the invoice: who pays the receiving fee, a correspondent bank fee or a platform fee. Some clients withhold tax at source. The IRS, for example, requires 30% withholding on pay to nonresidents for personal services performed in the United States unless a law or tax treaty exempts it; ask for proof of any withholding.

Invoice fraud often uses a message saying your bank details have changed. Put a rule in your terms: payment details change only through a documented process, confirmed by phone or portal through a contact the client already has. Use strong passwords and two-factor authentication on your invoicing and email accounts.

A late payment is stuck at one of four steps: the work is not accepted, the invoice is not approved, the payment is not released, or the money is not credited. Ask about the missing step. If the client says it paid, ask for the date, amount, currency, method and reference, and trace the payment before anyone sends a second one.

Example: invoice INV-104 for EUR 1,000 was due on 5 October. On 8 October send: “INV-104, EUR 1,000, due 5 October, has not been credited as of 8 October. Please confirm the release date and the responsible contact by 10 October, or send the method and transaction reference if it has been paid.” If finance says it is in the next payment run, ask for the date; the original due date still stands.

If the client disputes part of the work, ask which item and amount it means, and confirm the undisputed amount in writing. Keep the payment question and the work dispute in separate threads, and keep every message and document dated.

UK: when a business pays another business late, you can claim interest and debt recovery costs. An agreed payment date must usually be within 60 days for business deals and 30 days for public authorities; a longer period between businesses is allowed if it is fair to both. If no date was agreed, payment is late 30 days after the client receives the invoice or after you deliver the work, if that is later. Statutory interest is 8% plus the Bank of England base rate; GOV.UK’s example is GBP 85 a year, or 23p a day, on GBP 1,000 at a 0.5% base rate. You can add a fixed sum for recovery costs: GBP 40 on a debt up to GBP 999.99, GBP 70 up to GBP 9,999.99 and GBP 100 above that.

EU: if the contract sets no payment period, interest becomes payable automatically 30 calendar days after the client receives your invoice. Each country publishes a statutory rate; for 1 July to 31 December 2026 it is 10.52% in Germany and 12.40% in France. You can also claim a flat EUR 40 (or equivalent) for each invoice paid late. Late payment interest cannot be claimed from consumers.

Your contract’s governing law decides which rules apply. Check that before you add interest to a reminder.

Check the invoice rules of your country as well; GOV.UK, for example, lists what a UK invoice must include. Keep the issue date, the due date and the date the money arrived as separate entries.
