There isn't a single "right" way to do payment gateway integration — the right approach depends on how much checkout control you need versus how fast you want to launch and how much PCI-DSS scope you're willing to take on. Here's how the four main integration types compare:
| Integration Type | Best For | Trade-off |
|---|---|---|
| Hosted / redirect | Fastest launch, lowest PCI-DSS scope | Less control over checkout look and branding |
| API / direct (self-hosted) | Full control, seamless on-site checkout UX | Higher PCI-DSS scope and development effort |
| Mobile SDK | Native iOS / Android in-app checkout | Requires separate implementation per platform |
| Platform plugin | Shopify, WooCommerce, and similar storefronts | Limited to what the platform's plugin architecture allows |
A few examples of how our payment gateway integration services have solved real checkout, billing, and compliance challenges across industries.
Payment gateway integration cost varies widely depending on scope. Here are the main cost drivers, with rough ranges to set expectations — replace with your verified pricing before publishing:
| Cost Driver | Why it affects cost | Rough impact |
|---|---|---|
| Single vs. multi-gateway | Each additional gateway adds its own API, testing, and failover logic | Low → Medium |
| Direct API vs. hosted checkout | API integration requires more development and PCI-DSS scope than hosted redirect | Medium → High |
| Custom fraud rules | Building rule-based or ML fraud scoring beyond gateway defaults adds development time | Medium |
| Recurring billing / subscriptions | Dunning, proration, and lifecycle billing logic add meaningful scope | Medium → High |
| Multi-currency support | Localized pricing, currency conversion, and regional payment methods add integration work | Medium |
| Compliance level required | Higher PCI-DSS scope (e.g., full API integration) or HIPAA needs add security and audit work | Medium → High |
Most payment gateway integration projects fall in the 2–8 week range and scale in cost with the number of gateways, the depth of custom logic, and the compliance requirements involved.
