Not Sure How to Approach Payment Gateway Integration? Start Smart with a Proven Approach!
We’ve spent almost two decades developing high-scale B2B and B2C eCommerce and patent-processing solutions that include wide-ranging payment functionality, like:
- The BHN branded payments platform handles up to $1 billion in transaction volume and serves around 210000 merchants and 26 MM buyers.
- Poynt Omnicommerce payment-processing solution withstands $140 million in transaction volume per month and serves around 30 000 merchants.
The scale of our products and the resulting need to integrate them with scores of diverse payment systems have given us an ultimate grasp of the payment gateway integration process.
Our developers are equally skilled in employing the Direct Post, Hosted Payment Gateway, and Integrated payment gateway integration methods and are always prepared to use the one that fits best. They are also conversant with using SDKs. Furthermore, our R&D team has come up with a proprietary payment gateway integration framework to expedite the integration and cut the payment gateway integration cost.
