Wow Finstack

Fintech buying in Singapore lives or dies on the Monetary Authority of Singapore (MAS): licensing, local payment rails, and how customer data is handled under the PDPA decide whether a slick demo survives onboarding and audit. Use this checklist before you shortlist or sign.

How to evaluate a fintech provider in Singapore

• Confirm the licensing position first: check the MAS Financial Institutions Directory yourself, and pin down whether the vendor holds its own Payment Services Act licence (standard or major payment institution, money-changing, or digital payment token scope), white-labels another institution's licence, or operates inside the MAS regulatory sandbox.
• Treat security frameworks as the floor, not the finish: ask for the actual ISO 27001 / SOC 2 Type II audit, auditor, and date, plus PCI-DSS if card data is in scope, and for regulated work ask how controls map to the MAS Technology Risk Management (TRM) Guidelines and the cyber-hygiene notice that actually binds your licence class — MAS cancelled Notices 644 and 655 in 2024 and reissued the requirements under the Financial Services and Markets Act, so a vendor still citing them is working from a stale rulebook.
• Verify they speak Singapore's payment rails natively: get PayNow proxy resolution, SGQR, and FAST integration confirmed in writing, with settlement timing, reconciliation, and chargeback handling spelled out — 'we support PayNow' can mean anything from full proxy resolution to a static QR.
• Match the vendor to your sub-type and demand references in it: payments, regtech (KYC/AML and transaction monitoring), wealthtech, insurtech, and lending are different disciplines, so strength in card acquiring does not imply strength in automated onboarding or credit decisioning.
• Lock down the data and cost model before signing: under the PDPA you stay accountable for customer data the vendor processes, so require purpose limitation, breach-notification timelines, and sub-processor and overseas-transfer controls — and get written unit economics (per-transaction or percentage fees, platform costs, settlement and FX spreads) rather than one headline number.
