The verdict in three sentences
Adding online card payments to a Singapore SME website costs SGD 3,000 to 8,000 in integration in 2026, on top of Stripe's 3.4% + SGD 0.50 per domestic card transaction (international cards and currency conversion cost more). Unlike Morocco, where the CMI bank file takes 3 to 6 weeks (and integration runs 15,000 to 40,000 MAD), account approval in Singapore usually takes 1 to 5 business days, so the timeline is driven by development. To collect deposits and subscriptions, plan card saving and the link to your invoicing from day one, or you will pay twice.
What a card payment integration really covers
Most Singapore SMEs choose between Stripe, Adyen (for larger volumes), HitPay or a bank gateway. Stripe dominates small-business setups thanks to fast onboarding, 3-D Secure handled automatically and native support for PayNow QR, which many local B2B and B2C customers prefer to cards.
Three use cases come up repeatedly: the deposit on a quote (30 to 50% upfront), standard online sales, and monthly subscriptions (maintenance, training, rentals). The third requires Stripe Billing or an equivalent, with dunning for failed payments.
| Item (2026 estimate) | Range | Comment |
|---|---|---|
| Account setup fee | SGD 0 | Stripe, HitPay: no setup fee |
| Monthly platform fee | SGD 0 to 50 | Depends on provider and add-ons |
| Domestic card fee | 3.4% + SGD 0.50 | Stripe standard pricing |
| International card surcharge | +0.5 to 1.5% | Plus about 2% if currency conversion applies |
| PayNow fee | about 1.3% | Cheaper than cards for local payers |
| Simple integration (one-off payment) | SGD 3,000 to 4,500 | Brochure site or quote with deposit |
| Deposits + subscriptions + invoicing | SGD 6,000 to 8,000 | Saved cards, schedules, Xero or QuickBooks sync |
A realistic project timeline
Most SMEs expect two weeks, and in Singapore that is often achievable. ACRA registration, a director's ID, published terms, a refund policy and a privacy notice aligned with the PDPA are usually enough for approval.
| Step | Duration | Who |
|---|---|---|
| Account creation and KYC documents | 1 to 2 days | SME |
| Provider review and activation | 1 to 5 business days | Payment provider |
| Checkout development and test mode | 1 to 2 weeks | Agency |
| Subscriptions, webhooks, accounting sync | 3 to 7 days | Agency |
| Live testing and go-live | 1 to 3 days | Agency + SME |
| Total | 2 to 4 weeks | Development in parallel with approval |
For multi-currency pricing (USD or EUR customers), Stripe can present local prices and settle in SGD, but conversion fees of around 2% apply unless you hold foreign currency balances.
Mini case study
Rachel, managing director of a professional training center in Singapore, currently collects enrolments by bank transfer. She sells 120 enrolments a month at SGD 1,400 with a 30% deposit and wants to offer payment in 3 instalments.
- Volume collected online: 120 x 1,400 = SGD 168,000 per month
- Blended fees at about 2.6% (mix of PayNow and cards): SGD 4,370 per month
- Deposit + instalment integration: SGD 7,000 one-off
- Expected effect: 10% more enrolments thanks to instant payment, i.e. 12 x 1,400 = SGD 16,800 per month, plus one day a week of bank reconciliation saved

FAQ
Stripe or a local bank gateway?
For most SMEs under SGD 1 million in annual online volume, Stripe or HitPay win on speed and features. Above that, negotiating interchange-plus pricing with Adyen or a bank can save 0.5 to 1 point.
Can we take monthly subscriptions?
Yes, with Stripe Billing (around 0.7% of billing volume on top of payment fees). Budget SGD 1,500 to 2,500 of extra development for schedules and failed-payment retries.
How long until the first real payment?
Typically 2 to 4 weeks. Approval takes a few days, and development of 1 to 3 weeks sets the pace.
Do we need PCI DSS certification?
With hosted checkout or Stripe Elements, card data never touches your server, so a simple self-assessment questionnaire (SAQ A) is enough.
Should we offer PayNow as well as cards?
Yes for local B2B clients. PayNow fees around 1.3% are lower than cards, and many companies prefer it for invoices above SGD 1,000.
