Most businesses choose a payment gateway by comparing a few websites, picking the one with the lowest advertised fee and asking developers how long integration will take. That approach misses the factors that decide whether customers actually complete payments and whether finance teams can keep up. A more reliable method is to score a shortlist of payment gateway solutions against weighted criteria that reflect how your own business operates, then test the leading candidates before committing.
Define What Matters to You
Before looking at any provider, write down your priorities. A business selling across several Asian markets with frequent withdrawals has very different needs from a local retailer with occasional refunds. List your markets, expected volumes, typical transaction sizes, payout requirements and regulatory obligations. Then assign weights to criteria such as coverage, conversion, reliability, reconciliation, payouts, compliance and cost, so that the final comparison reflects your real priorities. Agreeing the weights with all relevant teams before scoring prevents later arguments about the outcome.
Criterion One: Payment Method Coverage
Score each provider on whether it supports the methods your customers use in each market. In Malaysia that may mean FPX and DuitNow; in Thailand, PromptPay; in Indonesia, QRIS and virtual accounts; in the Philippines, GCash, Maya and QR Ph; in Vietnam, VietQR and MoMo; in India, UPI. Ask for a written coverage list distinguishing live methods from planned ones, and for collections versus payouts. Gaps in a single important market can outweigh strong coverage elsewhere.
Criterion Two: Checkout Experience
Ask each provider to demonstrate its checkout on mobile and desktop for your key markets. Score how methods are ordered, whether amounts and references are pre-filled, and what happens when an attempt fails. A checkout that offers an alternative method immediately after a failure, rather than an error page, can recover a meaningful share of payments that would otherwise be abandoned. Score also how clearly the checkout explains each step to customers unfamiliar with a method.
Criterion Three: Reliability
Banks and wallets experience downtime, and the gateway’s response determines how much revenue is lost. Score providers on how they monitor channel health, whether they reroute customers away from degraded channels and what acceptance or uptime data they can share. References from businesses with similar volumes in your markets give the most realistic picture of performance during busy periods. Ask how customers are informed when a channel is unavailable and how quickly normal routing resumes.
Criterion Four: Confirmation and Reconciliation
Strong payment gateway solutions confirm payments in real time through signed webhooks and match each payment automatically to its order using unique references. Score providers on notification speed, verification methods and the quality of their reports. Ask your finance team to review sample reports, since they will use them daily. Weak reconciliation creates manual work that grows with every new market and quickly outweighs any saving on fees. Good reporting also makes audits faster and reduces the time needed to answer customer queries.
Criterion Five: Payouts
If you send money to customers, partners or affiliates, score each provider’s payout capability. Consider supported rails, speed, bulk processing, beneficiary validation, real-time status with failure reasons, and controls such as velocity limits, allow-listing and approval workflows. Running collections and payouts through the same provider simplifies reporting, but only if the payout service is as strong as the collection side. Test payouts in the sandbox with deliberately incorrect details to see how errors are reported.
Criterion Six: Compliance and Security
Score providers on the evidence they supply, not on general descriptions. Request details of merchant and customer verification, transaction monitoring, anti-money laundering frameworks, certifications, licences in relevant markets and data protection measures. Ask about audit trails and how records can be exported. Remember that your own business must still confirm it may lawfully serve customers in each market, whatever the provider’s position. Providers that answer these questions openly are usually easier to work with over time.
Criterion Seven: Total Cost
Compare written quotations based on your expected volumes and market mix. Include transaction fees, payout charges, currency conversion margins, reserves, minimum commitments and settlement timing. Calculate an annual total for each provider rather than comparing headline percentages. A provider with slightly higher fees but better conversion and less manual reconciliation may produce a lower overall cost of payment acceptance. Include internal staff time in the calculation, since manual work is a real cost even when it does not appear on an invoice.
Testing the Leading Candidates
Once scoring narrows the field to two or three providers, request sandbox access and test realistic scenarios: successful payments, failures, duplicate notifications, refunds and payouts with incorrect details. Assess documentation quality and support responsiveness during testing. If possible, run a limited live pilot in one market and compare completion rates and confirmation times against your current setup. Note how quickly the provider responds to questions during testing, since this often predicts support quality after launch.
Making the Final Decision
Combine the weighted scores with the results of testing and pilots, and involve product, finance, operations and compliance teams in the final review. Confirm commercial terms in writing, including service levels and exit arrangements. A structured process like this turns a confusing market into a clear comparison, and helps ensure the payment gateway solutions you choose fit your business for years rather than months.
