The Challenge
The social friction of asking for credit payment is not specific to India. The decision to launch in three markets simultaneously — India, USA, and Germany — created technical requirements that a single-market launch would never have needed.
- Multi-currency display without separate codebases
- GDPR compliance for EU customers from day one
- A single payment processor covering all three markets
- WhatsApp API with consistent global behaviour and pricing
Our Solution
IndiaUSAGermany1 Codebase
- Currency context throughout the app — amounts display in local currency based on registered country
- GDPR compliance built from day one — explicit consent flows, privacy docs, EU-appropriate data handling
- Stripe over Razorpay — handles all three markets natively with one integration
- WhatsApp Cloud API over regional providers — consistent global pricing and API behaviour
Mistake caught early
Initial pricing was set in INR. When the global decision was made, pricing was rebuilt in USD — requiring changes to 5 pages, Stripe configs, and all copy. Lesson: price in a global currency from day one if global launch is planned.
The Result

+2 days
Extra dev time
One codebase, one database, one payment processor — three markets. Additional per-market work: pricing localisation and GDPR documentation only. The global-from-day-one approach cost approximately two extra days of development.
