How to choose a payment gateway: a 10-point checklist

The right payment gateway can raise conversion, cut fees and save hours of reconciliation. Use this checklist to compare providers with confidence.

1. Pricing model and total cost

Look beyond the headline rate. Compare flat-rate and interchange-plus options, and ask about monthly fees, chargeback fees, refund fees, PCI fees and early termination fees. Model your total cost on a realistic month of transactions. See how PayJunction prices.

2. Supported payment methods

Make sure the gateway supports all major card brands and the wallets your customers use, such as Apple Pay and Google Pay. If you sell on subscription, recurring support is essential.

3. Integration options

Check for plugins for your platform, a hosted checkout for quick setup and a well-documented API for custom builds. Good sandbox tools save weeks. Integrations.

4. Security and PCI scope

Tokenization and hosted fields reduce how much card data touches your systems — and your compliance burden. Payment security.

5. Fraud tools

Look for risk scoring, custom rules, 3-D Secure, AVS/CVV and protection against card testing. Fraud protection.

6. Approval rates

Ask how the provider helps reduce false declines — network tokens, account updater and clear decline codes all help.

7. Payout speed

Cash flow matters. Compare standard payout timing and whether faster funding is available. Payouts.

8. Reporting and reconciliation

You should be able to trace every payout to individual transactions, fees and refunds, and export data for your accounting software.

9. Omnichannel support

If you sell online and in person, one provider for both simplifies reporting and customer service. POS payments.

10. Support and contract terms

Find out how to reach support, how quickly they respond, and whether you're locked into a long contract.
