Payment gateways for SMEs: Stripe, Omise and PromptPay compared
Taking money online should be the easy part. Picking the right gateway — and wiring it up properly — is where projects stall.
Accepting payments online looks simple until you compare options. The right gateway depends on where your customers are, what they pay with, and how the money needs to flow back into your systems.
Stripe is the global default — superb developer tools, cards and wallets worldwide, and clean APIs that make automation easy. If you sell internationally, it’s usually the backbone.
For Thailand and the region, Omise (Opn) and local rails matter. Thai customers expect PromptPay and local cards, and a gateway that supports them converts far better than one that only takes international cards.
PromptPay itself deserves a mention: QR-based, near-instant, and cheap. For many Thai SMEs it’s the primary way customers want to pay, and building it in properly — with automatic reconciliation — removes a mountain of manual checking.
The gateway is only half the job. The real value is what happens after payment: the invoice that generates itself, the order that updates, the notification that fires, the reconciliation that just happens. That’s the automation we wire around whichever gateway fits — so getting paid stops being admin.
