Multi-Currency Billing

Worked on the launch of multi-currency billing support for AgencyAnalytics, enabling customers to subscribe and pay in their local currency for the first time.

Previously, the platform only supported USD transactions. The new billing system introduced support for:

• CAD

• USD

• AUD

• NZD

• GBP

• EUR

The project involved integrating multiple payment gateways while maintaining a seamless subscription and checkout experience across currencies and payment methods.

AgencyAnalytics uses Chargebee for subscription management and invoicing. Depending on the selected currency and payment method, customers would be routed through different payment gateway flows:

• USD transactions continued using the existing Braintree integration

• Non-USD credit card transactions were processed through BlueSnap

• PayPal supported purchases across all supported currencies

My role focused primarily on backend payment and subscription logic.

I worked on:

• Currency-based payment gateway assignment

• BlueSnap integration support for multi-currency payments

• Secure payment flow handling with 3D Secure verification

• Chargebee payment method attachment and subscription processing

To support the frontend checkout flow, I implemented backend endpoints that generated BlueSnap pfToken values, allowing the frontend to initialize secure hosted payment fields and complete 3D Secure authentication.

Once payment verification was completed, I worked on the backend logic responsible for correctly attaching payment methods and subscriptions to Chargebee using the appropriate gateway configuration based on the selected currency.

The result was a scalable international billing system that expanded purchasing flexibility for global customers while maintaining secure and compliant payment processing workflows.
