Mexico is a growing market for Indian IT, testing, design and back-office firms, helped by overlapping working hours with North American teams. To export services to Mexico from India without friction, agree the invoice currency and any withholding treatment in the contract, give the client complete international wire details, and list each invoice on your monthly EDF with "Mexico" in the Part 2B country column. Each invoice then has 9 months from its date to be paid in full.
Key takeaways
- US dollars are a common choice for cross-border service contracts with Mexican companies; pesos are possible. Agree the currency in writing.
- Payments to India usually arrive as international wire transfers. Domestic Mexican payment systems do not reach your Indian account directly.
- Mexico may require withholding on some payments to foreign service providers. India has a tax treaty with Mexico; involve your CA early.
- Mexican clients often have strict documentation requirements for paying foreign vendors. Ask what they need before the first invoice.
- One EDF per month covers Mexican and other clients alike, due within 30 days from the end of the invoice month.
Currency: dollars or pesos?
| Option | Why clients choose it | What it means for you |
|---|---|---|
| USD | Familiar for cross-border contracts; many Mexican companies hold dollars | Familiar to your bank; your rupee value moves with USD-INR |
| MXN | Easier for smaller Mexican clients with peso-only accounts | Ask your bank how it handles peso receipts and conversion |
| INR | Rare | No currency risk; 12-month realisation period applies |
Write the currency into your contract and show it on every invoice and in the Part 2B currency column. If you invoice in pesos, check with your bank before signing; not every bank handles every currency the same way.
Getting the payment to India
Mexican businesses pay domestic suppliers through local systems, but a payment to an Indian account goes out as an international wire, usually through correspondent banks. Give your client a one-page bank details letter with:
- Your account name exactly as held.
- Your account number.
- Your bank's name, branch address and SWIFT code.
- Intermediary bank details your bank recommends for USD (or MXN).
- Your invoice number, to be quoted in the payment reference.
Agree who bears transfer charges. If the client sends with shared charges, intermediaries may deduct fees and the credit will be smaller than the invoice. When the payment arrives, collect the FIRA and check the purpose code; the purpose code finder helps you tell your bank which code fits your service.
Withholding, the treaty and documentation
Mexican tax rules may require withholding on certain payments to foreign residents, depending on the type of service and where it is performed. We are not quoting rates or rules here, because they depend on the specific service and can change. Ask the client's tax or accounts team early whether they intend to withhold, and on what basis.
India and Mexico have a tax treaty (DTAA), which may limit withholding and allow you to claim credit in India for tax withheld. Clients may ask for proof of your Indian tax residency or other documents before applying a treaty rate. If tax is withheld, keep the certificate; you will need it for your foreign tax credit, and to explain to your bank why the credit is smaller than the invoice. The glossary entry on withholding tax gives the basic idea.
Mexican companies also tend to have formal vendor onboarding: tax identifiers, bank confirmations, signed contracts. Expect paperwork before the first payment and budget time for it.
Invoicing Mexican clients
Your invoice is an Indian export invoice; Mexican domestic e-invoicing rules apply to Mexican issuers, not to you. Still, ask the client what its accounts team needs to see. Common requests:
| Item | Why the client may ask |
|---|---|
| Client's legal name with company suffix (e.g. "S.A. de C.V.") | Matches their records |
| Client's tax identifier | For their own accounting |
| Purchase order number | Approval workflow |
| Description in English (and sometimes Spanish) | Easier internal approval |
| Currency and payment terms | Avoids conversion confusion |
| Your bank details with SWIFT | So they can pay |
If you are GST-registered and exporting under LUT, include "Supply meant for export under LUT without payment of IGST". The free export invoice generator adds this and handles foreign currency totals.
The EDF for Mexican clients
- Part 2B country column: Mexico.
- Currency column: USD, MXN or INR as invoiced.
- Recipient: the client's full legal name and address.
- Field 1.17: Mexico if every invoice on the EDF is to a Mexican client; otherwise follow your bank's guidance.
- Field 1.4: usually "Internet" for remote delivery.
A worked example
Sundial QA Labs Pvt Ltd in Chennai tests software for two Mexican companies and one in the US. Its December 2026 invoices:
| Invoice | Client | Country | Currency | Amount | INR value |
|---|---|---|---|---|---|
| SQL/26/121 | Grupo Ventana S.A. de C.V. | Mexico | USD | 11,800 | ₹9,86,000 |
| SQL/26/122 | Logística Andes S.A. de C.V. | Mexico | USD | 6,400 | ₹5,35,000 |
| SQL/26/123 | Redwood Fintech Inc | USA | USD | 9,000 | ₹7,52,000 |
Sundial files one EDF for December with three rows and ₹22,73,000 in field 1.22, due by 30 January 2027.
Grupo Ventana told Sundial during onboarding that it would withhold tax on payments to foreign vendors unless treaty documentation was provided. Sundial's CA prepared the documents the client asked for, and the client applied the treaty treatment it considered appropriate. When payment arrived slightly below the invoice value, Sundial gave the bank the withholding certificate alongside the FIRA. Its CA will use the same certificate for the foreign tax credit.
All three invoices are under ₹10 lakh, so Sundial can close the EDPMS entries with a quarterly realisation declaration once paid.
Realisation timing
| Invoice date | Expected payment (60-day terms) | 9-month realisation deadline |
|---|---|---|
| 10 December 2026 | 8 February 2027 | 10 September 2027 |
| 18 December 2026 | 16 February 2027 | 18 September 2027 |
| 22 January 2027 | 23 March 2027 | 22 October 2027 |
Vendor onboarding can delay the first payment from a new Mexican client by weeks. Start onboarding before the first invoice, and if a payment drifts, chase in writing and ask your bank for an extension before the deadline.

Frequently asked questions
Should I invoice Mexican clients in USD or pesos?
US dollars are a common choice for cross-border service contracts, and pesos are possible if your bank handles them smoothly. Agree the currency in the contract and enter it in the Part 2B currency column.
Do Mexican companies withhold tax on payments to Indian service providers?
Some payments may attract Mexican withholding depending on the service. India has a tax treaty with Mexico that may reduce it. Ask the client early and involve your CA; keep any withholding certificate.
What goes in the EDF country column for a Mexican client?
"Mexico", on each Part 2B row for that client. One EDF can cover clients in several countries.
How do Mexican clients pay an Indian bank account?
By international wire transfer, usually through correspondent banks. Provide your account details, SWIFT code and any intermediary bank details your bank recommends.
How long do I have to receive payment from Mexico?
Nine months from each invoice date for foreign-currency invoices, or 12 months for rupee invoices. Your AD bank can extend the period on a reasoned request.
Bottom line
Exporting services to Mexico works smoothly when currency, withholding and onboarding paperwork are settled before the first invoice. Then it is a standard monthly EDF with "Mexico" in the country column and a watch on each invoice's realisation date. Build your declaration with the free EDF form generator.
