The work is done, the client is happy, and the money takes weeks. A familiar story for agencies, developers and consultants with clients abroad. Most of the time the delay is not bad faith but an inconvenient invoice: the wrong currency, incomplete details, a single payment option. Here is how to issue invoices to international clients that get paid quickly.
In short: the invoice should be clear to the client's accounts team without questions, include a card payment link and bank details, and state the due date and currency. Automatic reminders do the rest.
What every invoice must include
- Invoice number, date and due date.
- Full details of your company and the client: name, address, registration and tax number where applicable.
- Line-item description of services, quantity, price, total.
- Currency and tax information where needed (for example a reverse charge note for EU B2B).
- Bank details: IBAN, SWIFT/BIC, bank name, payment reference.
- A link to pay by card or another online method.
How to speed up payment
| Technique | Effect |
|---|---|
| Invoice in the client's currency | Fewer approvals and conversions on their side |
| Several payment methods | The client picks the familiar one: transfer, card, local method |
| Short payment terms | 7–14 days instead of 30 shortens the cycle |
| Prepayment or milestones | Less risk and smoother cash flow |
| Automatic reminders | Polite and no manual work |
A reminder sequence
- 3 days before the due date — a friendly reminder with the payment link.
- On the due date — a notice that payment is due today.
- 3 days after — a follow-up with a copy of the invoice.
- 10 days after — a call or message from the account manager.
How not to lose money on conversion
If you invoice in dollars and the client pays from a euro account, their bank converts at its own rate and intermediary banks may deduct fees. A multi-currency business account with local details in the right currencies lets you receive funds without unnecessary losses.
Frequently asked questions
Which currency should I invoice in?
Preferably the client's currency or the one agreed in the contract. That speeds up approval and lowers their costs.
Does an invoice need a stamp and signature?
In most countries an electronic document with full details is enough for international B2B invoices. If the client requires otherwise, fix it in the contract in advance.
How do I automate invoicing?
Connect the invoicing service to your CRM: deal closed — invoice created and sent; payment received — status updated. This is part of our CRM systems work.
