How the Stripe Integration Works
Once Stripe is connected for a customer, Vayu remains the source of truth for customer, contract management, and invoicing. Stripe will be used solely for payments. After a contract is active, invoices are generated in Vayu. Upon approval, invoices can be synced to Stripe automatically or manually, depending on configuration. Invoices can also be auto-collected. Set Stripe as the payment provider by going to a Customer profile, then selecting Settings. Scroll to Configurations and choose Stripe as your Primary Payment Provider.

Invoice Synchronization Flow
When an invoice is approved in Vayu, one of two sync paths applies:- Automatic sync (default):
Approved invoices are immediately pushed from Vayu to Stripe without manual action. - Manual sync (optional):
Users can manually trigger invoice sync if auto-sync is disabled.

From Vayu invoice to Stripe invoice
Once synced, each invoice in Vayu includes a clickable reference that opens the corresponding Stripe invoice. This allows finance teams to move seamlessly from operational billing (Vayu) to payment execution (Stripe).Payment methods and customer experience
Stripe supports multiple payment methods, including:- Credit cards
- ACH / wire transfers
- Direct online payment links

Payment status updates back to Vayu
After a payment attempt:- Stripe updates the payment intent status (success or failure).
- Vayu retrieves this status and updates the invoice accordingly.
- Successful payments automatically update the invoice status to Paid in Vayu.
- Failed payments surface as part of Vayu’s outstanding balances (OOS) and AR workflows.
Configuring the Stripe Integration
Go to your Stripe and get an API key for your Stripe account. Back in Vayu, go to Integrations and go to the Stripe panel. Click on Manage. Once there, you will have three things to configure. First, paste your API key in the text bar (which you can modify later).
