Payment Processing Fees Explained for SMBs in SEA
Quick Answer: Payment processing fees are charges deducted from each transaction when a customer pays digitally — typically comprising interchange, scheme, and gateway components bundled into a single merchant discount rate (MDR). For SMBs in Singapore, Malaysia, and the Philippines, fees vary by payment method, card type, and whether the transaction is domestic or cross-border. QR-based and bank transfer methods typically carry the lowest fees; credit cards the highest.
Digital payments now account for the majority of consumer spending across Southeast Asia. Statista SEA e-commerce the region's e-commerce market surpassed USD 200 billion in 2025. Every one of those transactions carries a processing cost — and for SMBs operating on thin margins, understanding exactly what those costs are is not optional.
Most small business owners see a single deduction from their settlement and assume it is one flat fee. It is not. Payment processing fees are made up of several distinct layers, each charged by a different party in the payment chain.
What Are the Different Components of a Payment Processing Fee?
A typical card payment passes through multiple parties before the merchant receives funds. Each party takes a cut:
- Interchange fee — paid to the cardholder's issuing bank. This is set by the card network (Visa, Mastercard) and varies by card type (credit vs. debit), country of issue, and transaction category.
- Scheme fee — charged by the card network itself (Visa, Mastercard) for using their infrastructure.
- Acquirer or gateway fee — charged by the payment processor or gateway that connects the merchant to the banking system.
For most SMBs, these three components are bundled into a single rate called the merchant discount rate (MDR). The MDR is expressed as a percentage of the transaction value, sometimes with a small fixed fee per transaction.
Non-card payment methods — QR payments, bank transfers, and digital wallets — typically carry lower MDRs than credit cards because they bypass the card network entirely and carry lower fraud and chargeback risk.
How Do Fees Differ by Payment Method Across Singapore, Malaysia, and the Philippines?
Fee structures vary significantly by payment method and market. The table below outlines the general cost hierarchy:
| Payment Type | Examples by Market | Relative Fee Level |
|---|---|---|
| Credit card | SG: Visa/MC/Amex · MY: Visa/MC · PH: Visa/MC | Highest |
| Debit card | SG/MY/PH: Visa/MC debit | Moderate–High |
| Digital wallet | SG: GrabPay, ShopeePay · MY: Touch 'n Go · PH: GCash, Maya | Low–Moderate |
| QR / Instant transfer | SG: PayNow · MY: DuitNow QR · PH: QR Ph | Lowest |
| Bank transfer | SG: PayNow · MY: FPX · PH: InstaPay, PESONet | Lowest |
| BNPL | SG/MY: Atome, Grab PayLater | Varies — often merchant-funded |
Credit card MDRs in Southeast Asia typically fall between 1.5% and 3.5% depending on card type and issuer country. Local QR and bank transfer methods often carry the lowest fees of all, which is why a growing number of food and beverage operators have shifted toward QR-first checkouts.
What Are Cross-Border and Currency Conversion Fees?
When a customer pays using a card or wallet issued in a different country, two additional costs typically apply:
- Cross-border fee — charged by the card network or wallet provider for processing an international transaction.
- Currency conversion (FX) fee — applied when the transaction currency differs from the merchant's settlement currency.
For markets like Singapore, which attract significant tourist and business travel volumes, cross-border acceptance is operationally important. A retailer on Orchard Road may serve customers using WeChat Pay, UPI, or PromptPay in a single afternoon. Each of those transactions settles at T+2 rather than the next business day applicable to domestic transactions — a cash flow distinction worth tracking.
The Monetary Authority of Singapore (MAS), which licenses payment service providers under the Payment Services Act, requires that licensed entities disclose fee structures clearly. Businesses should always confirm whether a quoted rate is all-in or excludes FX and cross-border components.
Are There Fees Beyond the Transaction Rate?
Yes. Depending on the provider, businesses may encounter:
- Monthly or platform fees — charged regardless of transaction volume
- Setup or onboarding fees — one-time charges to activate a merchant account
- Chargeback fees — levied when a customer disputes a card payment, typically between USD 15–25 per dispute in addition to the reversed transaction value
- Payout or withdrawal fees — charged when funds are transferred from the payment platform to the merchant's bank account
- Minimum monthly fees — if a merchant's transaction fee total falls below a threshold, some processors top it up
Understanding the full cost of card acceptance — not just the MDR — is essential for accurate margin calculation.
Frequently Asked Questions
Q: How do payment processing fees work for small businesses?
Payment processing fees are deducted automatically from each transaction before the merchant receives their settlement. They are made up of interchange, scheme, and gateway components — typically bundled into a single MDR percentage. For example, a 2% MDR on a S$100 sale means the merchant receives S$98. Fee rates vary by payment method, card type, and whether the transaction is domestic or cross-border.
Q: What is an MDR and how is it calculated?
MDR stands for merchant discount rate — the all-in percentage a merchant pays per transaction to accept a digital payment. It is calculated as a percentage of the transaction value and may include a small fixed per-transaction component. A S$200 card payment with a 2.5% MDR results in a S$5.00 fee deducted before settlement. Rates differ by payment method: credit cards carry the highest MDRs; QR and bank transfer methods typically carry the lowest.
Q: What payment processing fees should Singapore merchants expect?
Singapore merchants typically pay the lowest fees on PayNow transactions, which use the domestic instant payment rail. Credit card MDRs generally range from 1.5% to 3.5% depending on card type. Cross-border payments — such as WeChat Pay or UPI accepted from tourists — may carry additional scheme fees.
Q: Are there payment processing fees in Malaysia for DuitNow QR?
Yes, though DuitNow QR transactions typically carry lower fees than card payments because they bypass card network infrastructure. Malaysian businesses can accept DuitNow QR alongside FPX bank transfers and Touch 'n Go through gateways that support the full local stack. Most per-transaction-only gateways apply no monthly fees for this coverage.
Q: What fees do Philippine merchants pay for GCash and QR Ph transactions?
GCash and QR Ph are among the lowest-cost payment methods available to Philippine merchants, with fees typically below card MDRs. Card transactions in the Philippines carry standard Visa/Mastercard MDRs. The Bangko Sentral ng Pilipinas (BSP) regulates payment service providers operating in the Philippines.
Q: How do payment gateway fees compare for Southeast Asian SMBs?
Most major gateways in the region such as HitPay and Stripe charge per-transaction fees with no monthly fees for standard accounts, so the cost difference comes down to per-method rates and local payment coverage. HitPay's primary advantage for Southeast Asian SMBs is breadth of local payment methods — including PayNow, DuitNow QR, QR Ph, GCash, Touch 'n Go, and regional cross-border wallets — that Stripe does not fully support in all three markets. Stripe is a strong choice for globally focused businesses or developer-led integrations requiring 135+ currencies. For businesses primarily transacting with local customers in Singapore, Malaysia, and the Philippines, comparing per-method rates across providers — not just headline card rates — gives the most accurate picture of total cost.
