The most cost-effective way to pay an Indian supplier from the UK is through a currency specialist that converts GBP to INR (or USD) at a transparent, agreed margin and routes the payment to the supplier’s bank through an Authorised Dealer bank — so they receive a valid Foreign Inward Remittance Certificate (FIRC). Banks can handle the payment too, but usually apply a wider exchange-rate margin and give you fewer tools to manage timing and rate risk.
This guide is for UK businesses paying suppliers, manufacturers, IT firms or contractors in India — whether you import goods, outsource software and services, or settle regular invoices in rupees or US dollars. It covers how the payment actually works, the India-specific paperwork your supplier needs, and how to protect your sterling cost when the GBP to INR rate moves.
How do you pay an Indian supplier from the UK?
Payments from the UK to India are sent through the SWIFT network into the supplier’s Indian bank account. Under India’s Foreign Exchange Management Act (FEMA), administered by the Reserve Bank of India, every payment received from abroad is treated as an “inward remittance” and must land at an Authorised Dealer (AD) bank — the major Indian banks such as SBI, HDFC, ICICI and Axis all qualify.
To send the payment correctly, you’ll usually need the supplier’s full legal name, bank name, account number, the bank’s SWIFT/BIC code and, in most cases, the IFSC code. Getting these right matters — a missing or wrong detail is the most common cause of delayed payments to India. Our explainer on the difference between an IBAN and an account number covers how international routing codes work.
An IFSC (Indian Financial System Code) is an 11-character code that identifies the exact Indian bank branch receiving the payment. India does not use IBANs, so the IFSC plus the account number is what routes the funds to the right place. Every payment must also carry an RBI purpose code describing why the money is being sent — for example, separate codes exist for software and IT services versus imported goods. Ask your supplier to confirm the correct purpose code before you send, as a mismatch can delay or even return the payment.
What is a FIRC, and why does your supplier need one?
A Foreign Inward Remittance Certificate (FIRC) is an official document issued by an Indian bank confirming that a payment from overseas has been received in India. Many Indian suppliers — particularly exporters and IT firms — need it as proof of export earnings and to claim GST input credits, so the payment must reach their bank through an authorised channel that can generate a valid FIRC or e-FIRC.
This is the practical reason to choose a payment route carefully. Sending funds in a way that does not produce a clean FIRC can create compliance headaches for your supplier and strain the relationship. In our experience working with UK importers and firms outsourcing to India, suppliers consistently value a payment that arrives in full, on time, and with the documentation they need for their own records.
Should you pay your Indian supplier in INR or USD?
It depends on how your supplier invoices. Many Indian IT and software firms invoice in US dollars by default, while goods manufacturers may quote in either USD or rupees. Paying in the currency your supplier actually wants avoids an unnecessary second conversion at their end.
- Paying in INR: where INR settlement is supported, the GBP is converted to rupees and credited directly to the supplier’s account. This removes their USD-to-INR conversion and can give you cleaner pricing, since suppliers often build a buffer into USD quotes to cover their own currency risk.
- Paying in USD: the standard route for IT and services suppliers who hold or prefer dollars. You convert GBP to USD and send via SWIFT. Check the live GBP to USD rate when comparing.
Unlike the euro or US dollar, the rupee is a managed currency and cannot be freely held in an overseas account, so the decision is really about which currency reaches your supplier most efficiently — not about stockpiling INR. A specialist can talk you through which option suits each supplier. For the wider context on supplier payments, see our guide on the best way to pay overseas suppliers.
Bank vs specialist vs fintech account: how the methods compare
| Method | Typical FX margin | Speed to India | FIRC for supplier | Forward contracts | Best for |
|---|---|---|---|---|---|
| High-street bank (SWIFT) | Around 2–3% in the rate | 1–3 working days | Yes, via their bank | Rarely offered | Occasional one-off payments |
| Currency specialist (broker) | Transparent margin agreed up front | 1–2 working days | Yes | Yes | Regular or large supplier payments |
| Fintech multi-currency account | Around 0.5–1% | Often same or next day | Varies by provider | Usually not | High volumes of smaller payments |
Each model has a place. A fintech account suits a business making lots of small, app-based payments. A specialist suits larger or recurring payments where the rate, the FIRC documentation, and the ability to fix a future rate with a forward contract matter more than tapping a button. See our full business foreign exchange guide for how these fit together.
Step by step: paying an Indian supplier through a specialist
- Open your account early. Compliance and KYC checks take time, so set up before your first invoice falls due. See what to prepare in our guide on documents needed for large international transfers.
- Gather the supplier’s details. Full legal name, bank name, account number, SWIFT/BIC, IFSC code and the RBI purpose code — confirmed with the supplier in advance.
- Decide the currency. INR or USD, based on how your supplier invoices and what gives them the cleanest receipt.
- Lock your rate. Pay at the live rate for an invoice due now, or fix today’s rate for a future payment with a business forward contract.
- Confirm and pay by phone. Every Cambridge Currencies transfer is completed by phone with a dedicated specialist who checks the details with you before the payment goes out.
- Pass on the remittance reference. Make sure your supplier can obtain their FIRC for their export and GST records.
Costs and what to watch for
The biggest cost on an India payment is usually invisible: the exchange-rate margin built into the rate, rather than the upfront transfer fee. High-street banks commonly add around 2–3% to the interbank rate — our guide on why banks give worse exchange rates explains how this works.
Two other things to watch on the SWIFT route: correspondent banks in the chain can each deduct a fee, so your supplier may receive less than invoiced unless charges are accounted for, and you can trace any shortfall with an MT103. To avoid surprises, agree on your invoice that the full amount must arrive net of charges, and check the live rate on our currency converter before you commit.
Timing and currency risk on India payments
The GBP to INR rate moves daily with UK and Indian interest rates, inflation and risk sentiment. Through June 2026, sterling has traded broadly between around ₹126 and ₹128, supported by the Bank of England’s rate path. Even a one- or two-rupee move on a large invoice can change your sterling cost meaningfully. Our GBP to INR forecast for 2026 sets out the outlook in more detail.
For an invoice due in weeks or months — say against a purchase order with a fixed delivery date — a forward contract lets you fix today’s rate now and settle later, so your costed margin is protected whatever the market does. As Anthony Bull, CEO of Cambridge Currencies, puts it: “For importers, the danger isn’t the day you pay — it’s the gap between agreeing a price and settling the invoice. Fixing the rate up front means a deal you costed in March still makes sense when you pay in June.”
If your timing is flexible, a limit order can target a better rate, and our guide on currency hedging for UK businesses covers the full toolkit.
Why use a currency specialist for India supplier payments?
A specialist adds most value where the payments are regular or large and the paperwork matters. You get a transparent margin agreed in advance, support with getting the purpose code and FIRC right, and access to forward contracts to fix your costs — all handled by phone with a dedicated specialist rather than through an app. Cambridge Currencies works exclusively with FCA-authorised payment partners, Currencycloud (FRN 900199) and ScioPay (FRN 927951), so your funds are safeguarded at every stage.
The same approach applies across corridors. If you also buy from other markets, see our guides on paying suppliers in China, paying US suppliers in dollars and paying European suppliers in euros. UK businesses importing from India should also keep full records of every payment, in line with GOV.UK guidance on international trade.
Frequently Asked Questions
Can I pay my Indian supplier in rupees (INR)?
Yes, where INR settlement is supported. Your provider converts GBP to rupees and credits the supplier’s Indian account directly, which removes their own USD-to-INR conversion. Some suppliers, especially IT firms, still prefer to be paid in US dollars — confirm with them first.
Do I need a FIRC to pay an Indian supplier?
You don’t need it, but your supplier usually does. A Foreign Inward Remittance Certificate is their proof that the payment arrived from abroad, used for export and GST records. Sending through an authorised channel ensures a valid FIRC can be issued.
What details do I need to pay a supplier in India?
The supplier’s full legal name, bank name, account number, the bank’s SWIFT/BIC code, the IFSC code, and the RBI purpose code that describes the payment. Confirm all of these with the supplier before sending.
How long does a payment from the UK to India take?
Typically one to three working days via SWIFT, depending on the banks involved and cut-off times. See our guide on how long international transfers take for detail.
Should I pay my Indian supplier in USD or INR?
Pay in whichever currency your supplier invoices in. IT and software firms often prefer USD; goods manufacturers may accept INR. Paying in their preferred currency avoids a second conversion and can improve pricing.
How can I protect my business from rate movements on India payments?
A forward contract fixes today’s rate for a payment due later, so your sterling cost is locked between agreeing a price and settling the invoice. For flexible timing, a limit order can target a specific rate. A specialist can set either up for you.
