Your first overseas client: an invoice-to-payment records checklist

• Who is the contracting entity and who will actually pay?
• What are the deliverables, milestones and agreed invoice dates?
• What currency is the invoice in, and who bears transfer charges?
• Which recipient details, purchase-order reference or billing contact should appear?
• Which payment route will be used and what transfer reference should the sender include?

Put those answers in the contract or a retained written confirmation. A brand name or a contact’s email domain is not always the legal customer. If the payer will be a platform or another group company, note the relationship and ask the reviewer what evidence is required.

Do not decide the treatment from the address alone. Confirm the actual service, parties, place-of-supply position, registration circumstances and payment conditions with the responsible reviewer. If the applicable route uses an LUT, confirm the correct period and acknowledgement before relying on it.

The GST portal LUT guide explains furnishing the undertaking. CBIC’s invoice guidance describes required invoice particulars and the applicable export endorsement. Use the LUT worked example after establishing the route, rather than treating a template as an eligibility decision.

Verify receiving instructions through a trusted channel before sharing them. Keep the issued invoice PDF and its identifier. If the commercial agreement later changes, keep the appropriate supporting correction or note instead of losing the history by repeatedly editing an old copy.

1. 1Save the client or provider transfer confirmation.
2. 2Record the actual credited amount, currency, date and reference from the receiving record.
3. 3Obtain the route-specific remittance proof from the issuer.
4. 4Link the receipt to the intended invoice or invoices.
5. 5Review any difference using the original documents; keep unsupported deductions unresolved.

Different providers expose different trails. Read the Wise e-FIRC route guide or PayPal weekly FIRA guide for those specific cases. A remittance document received later should be attached to the existing payment, not recorded as a second receipt.

Prepare an invoice register, payment register, supporting evidence and exception list for the chosen period. Separate outstanding invoices from paid ones and preserve individual currencies. Ask your reviewer which GST and export reporting actions apply to the actual business.

For GST-registered businesses preparing GSTR-1, the official portal manual includes the export-invoice section. Use our source-linked EDF article to review the applicable authority route. A downloaded draft or JSON file does not establish that a bank or portal has accepted a filing.

Use the checklist below to see which record categories you have accounted for. Then start with a real invoice in Blackbird when you are ready. The CA handoff article shows a suggested folder structure and exception register for recurring monthly use.

Do I need a private limited company before my first foreign client?

This checklist does not require a particular entity type. Establish the actual contracting person or business, provider requirements and applicable registration obligations with the responsible adviser.

Can I invoice a foreign client in USD?

Record the agreed currency and confirm the applicable invoicing and receiving route. Blackbird supports foreign-currency invoices; choosing a currency does not decide tax or export eligibility.

What if a client pays only part of my invoice?

Retain the actual receipt, allocate the reviewed amount and keep the remaining balance visible. Do not change the invoice just to hide the difference.

Can I download the checklist without signing up?

Yes. The public checklist works in this browser without an account. It is a planning aid, not a filing or professional certification.

Does Blackbird receive the payment from my client?

No. Keep your bank or payment provider. Blackbird helps organize the invoice, receipt and supporting records around that payment.
