A complete guide to implementing multiple payment providers in your SaaS application for global reach and local payment methods...
## Why Multiple Payment Gateways?
Selling globally means accepting payments locally. While Lemon Squeezy handles international payments beautifully, Indian customers prefer UPI and local cards. Enter Dodo Payments.
## Architecture Overview
I built an abstraction layer that routes payments based on user location:
```typescript
interface PaymentProvider {
createCheckout(options: CheckoutOptions): Promise
handleWebhook(payload: WebhookPayload): Promise
cancelSubscription(subscriptionId: string): Promise
}
class LemonSqueezyProvider implements PaymentProvider {
// Implementation
}
class DodoPaymentsProvider implements PaymentProvider {
// Implementation
}
```
## Lemon Squeezy Integration
Perfect for international customers. Handles tax calculations, invoicing, and chargebacks automatically.
## Dodo Payments Setup
For the Indian market - supports UPI, Indian credit/debit cards, and net banking with lower fees.
## Key Lessons
1. Abstract payment logic behind interfaces
2. Always handle webhook idempotency
3. Test with real transactions early
4. Keep subscription status synced across providers
