Why Indexiz

Why Businesses Trust Indexiz with Payments

Payments are where bugs cost real money. We implement against gateway best practices, test every edge case and make reconciliation boring, which is how it should be.

Security First

Tokenisation, hosted fields, webhook signature checks and least-privilege keys on every integration.

Commerce Platform Depth

Magento, Shopify, BigCommerce, WooCommerce and custom checkouts, including headless storefronts.

Tested Edge Cases

Partial captures, refunds, declines, 3DS challenges, currency rounding and duplicate webhooks all covered by tests.

Reconciliation Built In

Finance gets payouts, fees and refunds matched to orders without spreadsheets.

Our approach

Secure by Default, Tested to the Last Decline.

We keep card data out of your systems, build every flow against sandbox and live test cards, and watch the first real transactions with you on launch day.
