Billing a UK client from India works like any other service export, with a few UK-specific habits worth knowing. Invoice in GBP (or another agreed currency), get paid into your AD bank, and declare every UK invoice on your monthly Export Declaration Form with "United Kingdom" in the Part 2B country column, filing within 30 days from the end of the invoice month. You then have 9 months from each invoice date to realise the full value.
Key takeaways
- Most UK clients expect invoices in pounds sterling (GBP). Agree the currency in the contract before the first invoice.
- Payments usually arrive by international wire, or via a payment provider that collects locally in the UK and remits to India.
- UK clients may ask for supplier onboarding details, and some may ask for tax paperwork. Ask early so payment is not held up.
- India and the UK have a tax treaty (DTAA). Whether it matters for you depends on whether any UK tax is deducted.
- Each UK invoice is one row on your monthly EDF, alongside invoices to clients anywhere else.
Invoicing a UK client
Currency
GBP is the natural choice for a UK business, and it saves your client conversion costs. Some UK clients, particularly those owned by US groups, may prefer USD. Whatever you agree, put it in the contract and use it consistently. The EDF records each invoice in its own currency, so a UK client billed in USD simply shows USD on its row.
What the invoice should show
UK accounts-payable teams are process-driven. An invoice that is missing a purchase order number or uses the wrong legal entity name is the most common reason for a delay. Include:
- the client's full legal name and registered address, exactly as on its supplier onboarding form;
- the purchase order (PO) number if they issued one;
- your legal name, address, PAN and GSTIN;
- invoice number and date, a clear description, amount and currency;
- payment terms (UK clients often work on fixed payment runs, so ask when theirs are);
- your bank details, including SWIFT code and any intermediary bank instructions your bank gives you;
- if you export under LUT, "Supply meant for export under LUT without payment of IGST".
The export invoice generator covers all of these.
VAT
UK VAT is your client's matter, not yours as an Indian supplier of business services in most cases; business clients typically account for VAT on services they buy from abroad under their own rules. If a UK client asks you to show particular wording or a VAT number on your invoice, follow its instructions and check with your CA if anything sounds unusual.
How UK clients pay
| Route | How it works | What you receive in India | What to check |
|---|---|---|---|
| International wire (SWIFT) | Client's UK bank sends GBP to your Indian bank | Credit with FIRA or bank advice | Intermediary and receiving charges; correct purpose code |
| Payment provider with UK collection | Client pays a UK account held by the provider; provider remits to India | Settlement into your bank | Provider's fees and conversion; what remittance proof it issues |
| Card or payment link | Client pays through a gateway | Gateway settlement | Gateway fees; settlement batching |
For any provider, check its current India help pages for how settlement and documentation work. For direct wires, our guide to direct SWIFT wire transfers covers what to expect.
Whichever route you use, the bank where the money lands is normally your AD bank, and that is where your EDF goes.
Tax paperwork and the DTAA
Some UK clients pay service invoices in full without asking for anything beyond your onboarding form. Others, depending on what you supply and their internal policies, may ask for evidence of your tax residence or other forms. If a client says it needs to deduct UK tax, ask exactly what rule it is applying and what document would reduce or remove the deduction.
India and the UK have a Double Taxation Avoidance Agreement. If tax is withheld in the UK, you may be able to claim credit for it in India with the right documents. A tax residency certificate from the Indian tax authorities is often what clients ask for. See our explainer on tax residency certificates.
Declaring UK invoices on the EDF
UK invoices go on the same monthly EDF as invoices to clients in other countries. For each UK invoice, the Part 2B row records:
- recipient name and address (the UK legal entity);
- country: United Kingdom;
- invoice number and date;
- currency (usually GBP) and amount;
- net realisable value after known deductions such as bank charges;
- description of services and SAC code;
- contract number and date, and remarks if useful.
If most of your work is for one UK client, field 1.17 (country of final destination) is simply "United Kingdom". If the month includes several countries, ask your bank how it wants Part 1 country and recipient fields filled.
Worked example
Northstar Research Pvt Ltd, Ahmedabad, does market research for UK retailers. In January 2027 it invoices:
| Client | Invoice date | Amount | Payment terms |
|---|---|---|---|
| Whitcombe Stores plc | 8 Jan 2027 | GBP 14,800 | 30 days, paid on monthly run |
| Elmbridge Home Ltd | 22 Jan 2027 | GBP 6,250 | 14 days |
Its January EDF is due on 2 March 2027 (February has 28 days). Both rows show United Kingdom and GBP, with SAC 998371 for market research and purpose code P1007 expected on the FIRAs, which Northstar confirms with its bank.
Whitcombe's invoice, about ₹16,00,000, is above ₹10 lakh, so the bank will want the invoice, FIRA and matching instructions to close it. Elmbridge's, about ₹6,75,000, can go into Northstar's quarterly realisation declaration. Realisation deadlines are 8 October 2027 and 22 October 2027 respectively, though both clients pay well inside that.
Realisation timing
UK clients are generally reliable payers, but payment runs, PO mismatches and onboarding delays can push payments back by weeks. Track each invoice against its 9-month deadline and chase early if an invoice is stuck in approval. If a client confirms it will pay late, ask your bank for an extension before the deadline.
This is general information, not legal or tax advice. UK tax and VAT points depend on your client's circumstances; your CA can advise on the Indian side.
Frequently asked questions
Should I invoice UK clients in GBP or INR?
GBP is the usual choice and keeps the 9-month realisation period. If you invoice and settle in Indian rupees, the realisation period is 12 months, but INR settlement has its own conditions under GST and FEMA. Discuss with your bank and CA first.
Do UK clients deduct tax from Indian suppliers' invoices?
Many pay service invoices in full, but practice depends on the service and the client. If a client says it will deduct UK tax, ask what rule applies and whether a tax residency certificate or other document would help, and keep any deduction certificate for your CA.
What goes in the EDF country column for a UK client?
"United Kingdom". Each UK invoice is a row in Part 2B with that country, alongside rows for clients in other countries on the same monthly EDF.
Is a UK client's VAT number needed on my invoice?
Some UK clients ask for it on supplier invoices for their own records. Follow the client's instructions; it does not change your Indian GST treatment, which depends on the Section 2(6) export conditions.
How long do I have to get paid by a UK client?
Nine months from the invoice date for foreign-currency invoices, or 12 months for rupee invoices. The AD bank can extend on a reasoned request.
Bottom line
UK clients are straightforward to bill if your invoices match their purchase orders and onboarding details. Create a clean GBP invoice with the free export invoice generator, then add it to your monthly EDF.
