Payment Gateway Development
Make Every Payment Step Work With Your Business
A payment gateway isn’t just where money comes in. It has to fit your checkout, update the right order and trigger what happens next. We integrate, customize and build payment functionality for WordPress and WooCommerce around the way your business actually sells.
Standard Payment Integrations Stop Where Your Rules Begin
Your Team Shouldn’t Have to Work Around Your Checkout
When an integration can’t apply a rule your business depends on, such as a deposit before fulfillment or terms for trade accounts, the exception lands on your team. Someone reconciles the payment, updates the order and chases its status by hand.
A payment flow built around how your business runs. We connect checkout rules, gateway APIs and payment outcomes to orders, billing and fulfilment, so a paid order moves forward on its own.

- Define how payments connect to orders, access and fulfilment
- Account for the rules and exceptions in your payment flow
Is This You?
When a Standard Payment Integration Isn't Enough
01
Your provider has no suitable WordPress or WooCommerce integration.
02
Your checkout needs payment rules the gateway plugin doesn’t support.
03
A payment result needs to trigger a specific workflow.
04
A gateway has to connect to a plugin you already rely on.
05
Payment events need to reach another business system.
06
Recurring payments need to behave differently from the standard flow.
07
You sell across regions with different payment requirements.
What We Do
Integrate, Customize or Build. Whatever the Flow Needs.
Payment Gateway Development
When your provider has no usable integration, we build one on its API, so you can sell with the processor your business needs.
Payment Gateway Customization
When the existing gateway almost works, we change how it behaves to match your checkout, payment and order requirements.
Payment API Integration
We connect your WordPress or WooCommerce site directly to a provider’s API and the workflows that depend on it.
Checkout & Payment Flow
We shape how payment options, customer details and checkout logic work together, including which methods appear for whom.
Order Workflow Management
Successful, failed, pending and refunded payments each trigger the correct order status and business action, without manual checking.
Subscription & Recurring Payments
Renewals, payment status and customer access stay in sync, so recurring revenue doesn’t quietly stop.
What Changes When Your Payment Flow Works Properly
Fewer payment-related problems at checkout
Payment status stays connected to the order
Business-specific payment rules apply automatically
Customers see the payment methods they expect
Less manual clean-up after transactions
A payment flow that can change as the business does

Attention to detail
Payment Providers We’ve Worked With
We’ve worked with payment providers across domestic and international markets, adapting each integration to the platform, the plugins and the transaction flow around it.
Why WisdmLabs
Why Businesses Choose WisdmLabs for Payment Development
Because payment development isn’t about connecting a gateway. It’s about making the whole transaction work with your business.
Beyond the Payment Button
We follow the transaction through checkout, confirmation, order status, refunds and the actions that follow, not just the charge.
Built Around Your Existing Site
Your WordPress setup, WooCommerce configuration, plugins and checkout stay as they are. The gateway is made to fit them.
No Standard Integration? We Build One
If your provider has no WordPress or WooCommerce plugin, we integrate with its API directly, as we did for Braintree, PayU and TechProcess.
Complex Payment Rules, Handled
Regional gateways, payment methods that depend on customer or location, recurring billing and order rules. We build around how you take payments.
Tested Before It Touches Live
Payments, declines, refunds and the order updates behind them are tested on staging first. Problems surface before a customer sees them.
WordPress Depth Behind the Code
14+ years of WordPress development, 2,000+ projects and WordPress Core Contributors on the team that builds your integration.

Frequently Asked Questions
Can you integrate a payment gateway that doesn’t have a WooCommerce plugin?
Yes. If the provider offers an API, we can build the integration on it. That’s how we built gateways for Braintree, PayU and TechProcess.
Can you customize an existing payment gateway?
Yes. We change how it behaves at checkout, which customers or orders it applies to, and what happens after payment, without forking it away from future updates.
Can you work with Stripe, PayPal, Authorize.net, PayU or regional gateways?
Yes. We’ve worked with each of these and with regional providers for domestic and international clients. If your provider isn’t listed, ask.
Can you integrate a payment gateway using its API?
Yes. API-level integration is how we handle providers without a ready-made plugin, and how we build payment flows the standard plugin can’t.
Can you fix failed payments or incorrect order-status issues?
Yes. We trace the problem through the full flow, from checkout to gateway response to order update, and fix the cause rather than the symptom.
Can you handle recurring or subscription payments?
Yes. We work with WooCommerce Subscriptions and similar setups to keep renewals, payment methods and customer access in sync.
Can you integrate payment functionality into an existing WordPress plugin?
Yes. We’ve added gateways to booking, event and membership plugins where the plugin itself didn’t support the provider.
Will you modify WordPress or WooCommerce core files?
No. We build with the platform’s action and filter hooks. Templates are extended, never edited in core.
How do you test payment gateway integrations?
On a staging copy of your site, using the provider’s sandbox or test mode. We test successful payments, declines, failures, refunds and the order updates that follow each one before anything reaches your live store.
Can you sign an NDA?
Yes. We’ve completed several projects under non-disclosure agreements.
How long does payment gateway development take?
A customization or a fix can take days. A new gateway built on a provider’s API takes longer. You get a timeline after we’ve mapped the current flow and the requirement.
I don’t know exactly what I need. Can you help?
Yes. Most clients come to us with a symptom, not a specification. Describe what happens today and what should happen instead. Working out the technical answer is part of what we do.
