Why a Custom Gateway

The Right Payment Method Lifts WooCommerce Checkout Conversion 10–30%

Your customers want to pay the way they prefer — UPI in India, M-Pesa in Kenya, Klarna in Sweden, BLIK in Poland, OXXO in Mexico, KNET in Kuwait, Boleto in Brazil. Generic global gateways often fail in regional markets, both technically (declined cards) and culturally (unfamiliar checkout). A locally-trusted payment method can lift checkout completion by 10–30%. We integrate any gateway with a public API into WooCommerce — refunds, webhooks, partial captures, subscriptions, 3DS2, SCA, RBI tokenisation, full PCI-aware architecture — all on a fixed price.

Who Hires Us for WooCommerce Payment Gateway Integration

Cross-Border Merchants Expanding to New Regions

A merchant launching in MENA, India, LatAm, or APAC who needs the locally-trusted payment method live before launch day. We integrate the regional gateway alongside their existing Stripe/PayPal so they enter the new market with the right payment mix from day one.

Stores in High-Risk or Vertical-Specific Industries

Industries that mainstream gateways will not touch (regulated supplements, adult, gambling, certain financial products, firearms) need specialised high-risk acquirers integrated properly. Generic plugins do not exist for many of these processors; custom integration is the only path.

Enterprise Merchants Adding Multi-Acquirer Smart Routing

Large merchants with significant international revenue benefit from routing transactions to the lowest-cost or highest-approval-rate acquirer per transaction. We build smart-routing gateways that can lift approval rates 3-7 percentage points — equivalent to free incremental revenue.

SaaS and Subscription Merchants Migrating Processors

Subscription merchants needing to migrate active subscriber tokens from one processor to another (e.g., off Recurly onto a direct Stripe integration). We handle the token migration with the gateway pair, preserve renewal dates, and design the customer email flow.

In depth

What to know before you start

The Business Case for a Custom WooCommerce Payment Gateway

Three patterns drive demand for custom payment gateway work, and all three deliver measurable ROI:

1. Regional Conversion Lift

A Polish merchant accepting only international Visa/Mastercard typically converts at 40-60% of what they could with BLIK added (BLIK accounts for 75% of Polish e-commerce transactions). A Mexican merchant adding OXXO captures the 50% of Mexican consumers who pay in cash. A Brazilian merchant adding PIX sees instant-payment adoption climb to 60%+ within 6 months. A Kenyan merchant adding M-Pesa unlocks a market segment that simply will not pay any other way.

The conversion lift from adding the locally-trusted payment method usually pays back the integration in the first 30 days.

2. Lower Transaction Costs

Direct gateway integration eliminates middleman markups. Stripe Connect via Shopify costs different rates than Stripe directly. A regional ACH/SEPA integration via your bank costs 10-25× less than card processing for high-AOV B2B transactions. We have helped merchants drop blended payment costs from 3.2% to 1.8% by integrating the right mix of methods directly.

3. Vertical-Specific Compliance

Some industries (gambling, adult, CBD, firearms, supplements, regulated financial products) cannot use mainstream gateways. They need specialised acquirers (CCBill, Authorize.Net high-risk, NMI, specific regional processors) properly integrated with WooCommerce. Generic plugins do not exist; custom integration is the only path.

How WooCommerce Payment Gateways Actually Work Under the Hood

A WooCommerce payment gateway is a class extending WC_Payment_Gateway with a defined contract: process_payment() (called when the customer clicks Place Order), process_refund() (called from the admin refund button), settings registration, and rendering of the customer-facing payment-method UI on cart/checkout. The gateway is registered via the woocommerce_payment_gateways filter.

Real production gateways also need: webhook receivers (registered as REST endpoints or admin-ajax handlers), saved-payment-method support (extending WC_Payment_Token_CC or _eCheck), Block Checkout compatibility (a JS payment-method registered via wc.wcBlocksRegistry), Subscriptions integration (extending the renewal flow), and proper Settings API integration. Skipping any of these layers ships a fragile gateway that breaks in production.
