An Indian SaaS company selling abroad has two problems that a domestic one does not: getting paid in another currency, and proving to the Indian system that the payment was what you say it was. Founders usually solve the first and discover the second at the end of the financial year, when someone asks for documentation that nobody was collecting.
The proof requirement is the part worth designing around. Zero-rated export treatment depends on payment arriving in convertible foreign exchange and on documentation linking that inflow to the specific invoice. Payment platforms issue the equivalent for cross-border collections, and the practical consequence is that your billing system needs to hold, per invoice, the currency, the settlement reference and the date the money actually arrived — not just the date the customer's card was charged. Those are different dates and the gap between them is where reconciliation goes wrong.
Currency choice is a product decision with financial consequences. Billing in the customer's currency raises conversion and reduces friction; billing in dollars universally simplifies your books at the cost of some conversion friction for the customer. Whichever you choose, decide where the exchange rate risk sits and be consistent — a subscription priced in one currency, collected in another and recognised in a third produces revenue figures that nobody in the company can reconcile with the bank statement.
Sales tax abroad is the obligation most Indian founders underestimate. Digital services sold to consumers in the EU, the UK, and various US states and other jurisdictions can create local tax registration or collection obligations that have nothing to do with Indian law and do not care that you have no presence there. Thresholds vary and change. This is precisely the problem a merchant of record is built to solve: they become the seller, take on the tax obligations, and remit to you. You pay a higher percentage for that, and for many companies selling to consumers or small businesses it is the correct trade.
Sitting against that is the direct route — your own payment gateway, your own invoices, your own compliance. It costs less per transaction and gives you the direct customer relationship, the ability to negotiate terms, and cleaner data. It suits enterprise sales with a small number of large invoices, where per-transaction cost matters little and control matters a lot. The pattern that works for many companies is direct for enterprise and a merchant of record for self-serve, rather than one model forced across both.
Two operational habits prevent most of the pain. Reconcile monthly rather than annually, so a mismatch is a small puzzle rather than an archaeology project. And keep the realisation clock visible — export proceeds arriving outside the permitted window change the tax treatment of an invoice you already booked as zero-rated, and by the time an accountant notices, the conversation with the customer that would have fixed it is a year stale.
