Overview

Stigg’s Invoicing Integration enables self-serve checkout flows with built-in invoice generation and payment collection. Customers select a plan, complete checkout, and Stigg automatically provisions their subscription and generates an invoice.

​

PLG flow: checkout with invoicing

Customers select a plan, enter payment details, and Stigg provisions their subscription automatically. An invoice is generated and the payment is processed.

​

Airwallex payment support

Airwallex is a Payment Service Provider (PSP) that Stigg integrates with directly. It is the recommended payment method for teams with cross-border or international revenue because it:

• Supports local payment methods across 150+ countries
• Reduces FX conversion costs compared to USD-only billing
• Authors invoices and collects payment in the customer’s preferred currency

Airwallex is available for the PLG checkout flow and as a payment method on SLG contracts.

​

Setting up

In the Stigg app, go to Settings > Integrations > Apps.

1. Select the Invoicing category
2. Select a third-party payment integration — Airwallex or Stripe
3. Complete the setup for that provider

Multiple integrations are supported. You can connect both Airwallex and Stripe simultaneously.
