Can I use my own gateway instead of Shopify Payments?

Yes. Shopify and other platforms support third-party gateways. Using Armour Payments can lower your effective rate and unify reporting across in-person and online sales.

Will connecting a gateway slow down my checkout?

No. A properly integrated, hosted gateway adds negligible load time and can speed checkout by enabling saved cards and digital wallets.

The short answer

Connect your gateway through your platform's official integration, keep card entry on a hosted field to limit PCI scope, enable tap-to-pay wallets at checkout, and match settlement to your accounting. Done right, you cut fees and reduce abandoned carts.

Use the official integration

Every major platform, Shopify, WooCommerce, Magento, BigCommerce, supports gateway plugins. Use the supported integration rather than a hack, so updates, refunds and reporting all work natively. Armour Payments connects to 100+ platforms; see integrations.

Keep PCI scope small

Choose an integration that hosts the card fields (tokenization or an iframe) so raw card data never touches your servers. This shrinks your PCI burden dramatically and is safer for your customers. More on this in PCI compliance for small stores.

Optimize for conversion

Enable Apple Pay, Google Pay and saved cards at checkout, minimize form fields, and never surprise shoppers with fees. Small changes lift completed orders. See the anatomy of a high-converting checkout.

Reconcile cleanly

Match your gateway's settlement reports to your accounting so payouts, refunds and fees line up. A clean reconciliation saves hours each month. Need help? Contact sales.
