To export services to Singapore from India, you invoice the Singapore client in SGD, USD or INR, get paid into your Indian bank, and list each invoice as a row in your monthly EDF with "Singapore" in the country column, filed with your AD bank within 30 days from the end of the invoice month. The full value must arrive within 9 months of the invoice date (12 months if you invoice or settle in rupees). Singapore clients are usually quick, organised payers, but some will ask tax questions — about withholding or treaty paperwork — that are worth settling before the first invoice.
Key takeaways
- Invoice in SGD or USD; SGD is friendlier for the client, USD is often simpler for your bank and books.
- Each Singapore invoice is one row in Part 2B; one EDF covers all clients for the month.
- Singapore clients may ask about withholding tax or your tax residency — let their adviser and your CA settle it, and price for it.
- India and Singapore have a DTAA, which may matter if tax is withheld.
- Under GST, services to a Singapore client are generally zero-rated if the Section 2(6) conditions are met.
Choosing the invoice currency
| Currency | Advantages | Things to watch |
|---|---|---|
| SGD | Client pays in its home currency; no conversion on their side | Your bank converts SGD to INR; check how its rates compare |
| USD | Familiar for many Indian banks and accounting setups; many Singapore firms pay USD routinely | Client may bear conversion; agree who pays charges |
| INR | Possible where RBI permits; realisation window is 12 months | Client takes currency risk; less common for Singapore B2B |
Whatever you choose, put the currency on the invoice and use the same currency in Part 2B. If the client pays in a different currency from the one invoiced, tell your bank so it can match correctly.
How Singapore clients typically pay
Most business clients pay by bank transfer. A cross-border wire from a Singapore bank to your Indian bank is the classic route: your bank receives it, credits your account in rupees (or into an EEFC account if you have one) and issues a FIRA with a purpose code.
Some exporters instead use collection accounts from payment services, which let a Singapore client pay locally and the service then remits to India. Each service has its own terms and documents, so check them before relying on one. Whatever the route, the Indian bank where the money lands is your AD bank for the EDF.
Ask clients to:
- quote your invoice number in the payment reference
- pay with charges borne by the remitter ("OUR") if your contract says so
- use your exact account name, account number and your bank's SWIFT code
Our article on bank details on an export invoice explains the intermediary bank question.
Tax paperwork your Singapore client may ask for
This is where Singapore engagements occasionally slow down. Singapore has its own rules on withholding tax for certain payments to non-residents, and whether they apply depends on the nature of the payment and where the work is performed. Some clients will simply pay your invoice in full; others will ask questions first.
What you might be asked for:
| Request | What it is | What to do |
|---|---|---|
| Confirmation of where services are performed | Helps the client decide on withholding | State it accurately in your contract and invoice |
| Tax residency certificate | Shows you're tax-resident in India, for treaty purposes | Your CA can help you obtain one |
| Treaty-related forms | Supporting claims under the India–Singapore DTAA | Let your CA review before you sign |
If tax is withheld, you may be able to claim credit in India — that's a tax matter handled through your return and Form 67. Our DTAA basics for service exporters explains the idea. Agree up front whether your fee is gross or net of any withholding, so you aren't surprised by a short payment.
A worked example: Tidewater Data Services LLP
Tidewater Data Services LLP, a fictional Kochi analytics firm, has two Singapore clients. In November 2026 it raised:
| Invoice | Date | Client | Currency | Amount | Work |
|---|---|---|---|---|---|
| TDS/E/26-27/071 | 05-Nov-2026 | Marina Bay Freight Pte Ltd | SGD | 12,800 | Demand forecasting model, milestone 2 |
| TDS/E/26-27/072 | 30-Nov-2026 | Orchid Health Pte Ltd | USD | 6,500 | Monthly dashboard retainer |
The EDF rows
In Part 2B, each invoice gets one row:
- Recipient and address: the client's registered name and Singapore address
- Country: Singapore
- Invoice number and date: as on the invoice
- Currency and amount: SGD 12,800; USD 6,500
- NRV: invoice amount, unless known deductions apply
- SAC: as agreed with the CA (Tidewater uses an IT-services code for analytics work)
- Contract no. and date: the SOW reference
At book rates of ₹64 per SGD and ₹84 per USD, field 1.22 is ₹8,19,200 + ₹5,46,000 = ₹13,65,200. The November EDF is due 30 December 2026.
Realisation: TDS/E/26-27/071 by 5 August 2027; TDS/E/26-27/072 by 30 August 2027. Both are under ₹10 lakh individually, so once paid they can be closed through a periodic realisation declaration.
GST for Singapore engagements
For GST, a service to a Singapore client is generally an export if the five Section 2(6) conditions are met: you're in India, the client is outside India, the place of supply is outside India, payment comes in convertible foreign exchange (or INR where RBI permits), and you aren't merely establishments of the same entity. Most exporters work under LUT and write "Supply meant for export under LUT without payment of IGST" on the invoice.
Singapore has its own GST system. Whether your client needs to account for anything on its side is the client's matter; don't add Singapore GST to your invoice unless an adviser tells you that you must.
Watch the "establishments of a distinct person" condition if you're billing your own Singapore group company — get your CA's view on intra-group billing.

Frequently asked questions
Should I invoice Singapore clients in SGD or USD?
Either works. SGD is convenient for the client; USD is often simpler for your own bank and books. Whichever you pick, use the same currency on the invoice and in the EDF's Part 2B row.
What goes in the country column of the EDF for a Singapore client?
Enter "Singapore" in the country column of the Part 2B row for that invoice. If you also fill field 1.17 (country of final destination) for a mixed-country month, your bank may accept "As per Part 2B".
Will my Singapore client deduct withholding tax?
It depends on the nature of the payment and where the services are performed under Singapore's rules. Some clients pay in full; others ask for residency documents first. Ask your CA, and agree in your contract whether your fee is gross or net.
How long do I have to receive payment from a Singapore client?
Nine months from the invoice date for foreign-currency invoices, or 12 months if invoiced or settled in rupees. If a client is late, your AD bank can extend the period on a reasoned request.
Is the India–Singapore DTAA relevant for service exporters?
It can be, mainly if tax is withheld in Singapore. The treaty and your tax residency certificate may help reduce or credit that tax. Your CA should review any treaty paperwork before you sign it.
Bottom line
Singapore clients are straightforward once currency, payment route and any tax paperwork are agreed at the start. Raise a clear invoice with our export invoice generator and list it in the monthly EDF form generator.
