BigPay Remittances · 2022 · 2 min read
Sending money to Singapore usually meant going through a bank or a money changer, and you often didn’t know the rate until it was done.
People already used BigPay every day, so we added Singapore transfers to it.

BigPay contacts only need a mobile number. PayNow takes a mobile number, NRIC or UEN, and bank transfers ask for the bank and account number.

Pending shows when it should arrive, and you get a notification once it’s delivered. If it’s refunded, the receipt says so and the money goes back to your BigPay balance.
Most of my time went into what happens when things go wrong. Hitting a daily limit, a check failing after the OTP, transfers to Singapore being down for a while. Once those were designed, the main flow could stay short.
