How a Fintech Validated Payments Across 4 Markets in Under 10 Days
Before a critical international launch, local users in Malaysia, Indonesia, Singapore, and Thailand ran real transactions across 60+ payment methods — surfacing 30+ geo-specific friction points in a single sprint.
Launch-ready across four markets
Expanding into Malaysia, Indonesia, Singapore, and Thailand meant the payment experience had to work flawlessly with regional banks and wallets — before a critical launch, not after.
Local users + live war-room
Local users on Android and iOS ran real transactions across 60+ payment methods, with a real-time war-room linking them directly to the engineering team for rapid feedback loops.
30+ insights, under 10 days
The engagement surfaced 30+ critical usability and experience insights in under 10 days, directly shaping product alignment and a confident launch strategy.
One gateway, four very different markets
A payment flow that works perfectly in one country can break quietly in another — a wallet redirect that fails, a bank that times out, a confirmation screen that reads wrong in the local context. The client needed geo-specific user insights to refine platform stability and confirm compatibility with the regional banks and wallets its new customers actually use.
That meant testing real transactions across a wide spread of payment rails — major cards from Bank Mandiri, BCA, Maybank, HSBC, Kasikorn Bank, and OCBC, alongside the wallets people reach for first: GoPay, ShopeePay, Boost, TnG, TrueMoney, and GrabPay. Doing this in time for a critical launch window left no room for slow, sequential testing.
- A critical market launch riding on payment reliability across four countries
- Compatibility with dozens of regional banks and wallets, each behaving differently
- User trust — a failed first transaction in a new market is hard to win back
- A tight launch window with no room for slow, country-by-country testing
Real Transactions, Local Users, and a Live War-Room
Engaged a diverse group of verified local users across all four target countries, on a wide range of Android and iOS devices — so findings reflected each market, not a proxy for it.
Users completed real transactions across 60+ payment methods — major regional cards and the most-used digital wallets — rather than simulated or sandboxed flows.
A real-time war-room connected users directly to the engineering team, enabling rapid feedback loops and quick refinements to geo-specific issues as they surfaced.
Findings on payment processing, user behaviour, and device-specific interactions were consolidated into data-driven insights that fed straight into product and launch decisions.
30+ Insights. 60+ Payment Methods. Under 10 Days to Launch-Ready.
Usability and experience findings that directly influenced product decisions.
Real card and wallet transactions validated across banks and providers.
Android and iOS handsets across multiple locations in four markets.
From kickoff to a confident, data-backed launch strategy.
By putting real transactions in the hands of local users — and wiring them straight into the engineering team through a live war-room — the client uncovered 30+ critical usability and experience insights in under 10 days. The findings exposed regional differences in payment processing, user behaviour, and device-specific interactions that no remote lab test would have caught. The result was a payment gateway optimized for usability, security, and transaction stability across all four markets, and a confident, data-backed launch into Southeast Asia.
What This Teaches About Launching Payments in New Markets
A wallet redirect that fails only on a specific Indonesian bank, or a confirmation screen that reads wrong locally, rarely shows up in a remote lab. Real users in-market surface the friction that actually loses customers.
Connecting testers directly to engineers turned a normally slow, sequential cycle into rapid feedback loops — 30+ insights in under 10 days, fast enough to fix issues before launch rather than after.
Coverage across 60+ real cards and wallets — the specific banks and wallets each market relies on — is what separates "it works in our sandbox" from "it works for the customer at checkout."
