Most Southeast Asian SMBs pick a payment processor the way they pick a taxi—whoever showed up first. But below ₹10M ACV, your processor is cash flow. Stripe takes 2.9% + ₹30 per transaction and settles in 2 days. Razorpay takes 2% on some corridors and 3.5% on others, but holds for 5 days. Wise moves cross-border cash 20% cheaper than Stripe but only handles payouts, not inbound collections. GCash and OVO are instant in the Philippines and Indonesia but invisible outside their borders. The margin gap between the wrong processor and the right one is not 0.3%. It is 1–2 percentage points of transaction volume, plus hidden settlement float that costs you 5–15 days of working capital per month. Pick correctly, and you keep the cash. Pick wrong, and your business runs on borrowed time. Stripe: The default that works if you have scale Stripe is ubiquitous in Southeast Asia. Every SMB starts here because Stripe's merchant dashboard is readable, the API docs work, and settlement is predictable. But Stripe is not cheap at scale below ₹10M ACV. Malaysia, Singapore, Indonesia: 2.9% + ₹30 per card transaction. ACH or local bank transfer is 1%, but no one uses it. Settlement window: 2 business days for most corridors. You swipe Monday, cash lands Wednesday. Hold period: 7 days (rolling) on new accounts, 0 days once you hit ₹50K monthly volume. Stripe reserves the right to hold 30 days if chargeback rates spike above 1%. Cross-border payouts: 1% + ₹30 minimum. Slow and expensive for distributed teams or supplier payments. Monthly fees: None below ₹100K monthly processing. Platform fee is 0.5% if you use Stripe's hosted checkout. The Stripe trap: You build your whole stack on Stripe's API—invoicing, subscription billing, marketplace payouts, expense tracking. Switching later costs months of integration work. That lock-in is why Stripe can afford to stay expensive. For a ₹5M ACV B2C marketplace, Stripe is ₹150K+ per year in processor fees alone. That is a senior hire. Stripe wins if you need global coverage, instant API onboarding, or you already use Stripe Connect for marketplace payouts. Stripe loses if your customers are concentrated in one country and you move 70%+ of volume through a local payment method (GCash in the Philippines, OVO in Indonesia). Razorpay: Cheaper per transaction, slower to cash Razorpay is the Southeast Asia scrappier alternative. Cheaper on headline rate, but the settlement math is less obvious. Cards in India (INR): 1.8% + ₹30 per transaction. If you are billing Indian customers in rupees, this is the cheapest option. Cards in Malaysia, Singapore, Indonesia (SGD, MYR, IDR): 3.5% + local equivalent. Not cheaper than Stripe, actually more expensive once fees align. Local methods (UPI in India, FPX in Malaysia): 0% + settlement fee of 0–0.5%. If your B2B customers pay via FPX or local transfer, Razorpay is 2.5 percentage points cheaper than Stripe. Settlement window: T+1 for local methods, T+5 for cards (Friday payouts hold until Monday). So you can swipe Tuesday and wait until next Wednesday for the cash. Hold period: 14–21 days rolling on new accounts. On day 1, Razorpay holds the first ₹2L. They release it in tranches as you hit volume thresholds. Payouts: 0.5% for intra-India transfers. Outside India, costs jump to 2–3% + intermediary bank fees. Razorpay wins for B2B recurring in India and Malaysia (where FPX adoption is 40%+ for business payments). Razorpay loses for international payouts and for merchants heavily reliant on cross-border credit cards. The hidden cost: Razorpay's 5-day card settlement means your daily balance sheet is a guess. If you bill customers on day 1 and do not see the cash until day 6, reconciliation is harder, working capital stress is higher, and your cash conversion cycle extends by 3–4 days per month. Wise (formerly TransferWise): Cross-border payouts, not collections Wise is not a payment processor in the traditional sense. Wise does not collect from customers. Wise moves cash out of your business—to suppliers, contractors, or team members abroad. But for that use case, Wise is 1–2 percentage points cheaper than Stripe and 4–5 days faster. Payouts to India: 0.6% + midmarket FX rate (no markup). For a ₹1M payout to contractors, you save ₹15–20K versus Stripe or Razorpay. Payouts to Philippines, Indonesia, Vietnam: 0.8–1.2% + real FX. Wise beats local banks and remittance services by 1–2%. Settlement window: 1–2 business days for most SE Asia routes. Money lands in the recipient's account by Tuesday if you send Monday. Hold period: None. Wise moves cash immediately once verified. No rolling holds, no 7-day reserves. Collections: Wise does not handle inbound payments. You cannot use Wise to accept customer payments. Monthly costs: No minimum. You pay per transaction, nothing more. For a distributed team or supplier network, Wise can save 20–30% of payout costs versus Stripe. A ₹10M ACV business paying ₹50L to contractors and vendors can save ₹5–10L annually by switchi
