Smart Invoicing API
- In one line
- Billing your own applications can call
- Capabilities
- 6, shipped together
- Installs onto
- A running ERPNext instance
If your product, portal or marketplace raises invoices, you can rebuild billing inside it or call the ERP that already does it correctly.
The second is cheaper and keeps one set of books. Invoices, pricing rules, payment capture, subscriptions, PDFs and webhooks arrive as a documented API with a sandbox: integration in days, not months.
What the module actually does
REST endpoints for invoicing, payment capture, subscriptions, multi-currency and webhooks, with a sandbox to build against.
- 01
Invoice endpoints
Create, update, cancel and query over JSON: line items, taxes, discounts, custom fields.
- 02
Payment capture
Razorpay, Stripe, PayPal and bank connectors, with capture, refunds and settlement reconciled against the invoice.
- 03
Subscription billing
Monthly, quarterly or annual cycles, generated, collected, prorated and reminded automatically.
- 04
Pricing rules
Customer rates, volume slabs, promotional codes and tiered pricing by API parameter, with a price preview before the invoice is raised.
- 05
Tax and currency
Correct Indian tax treatment: IRN generation, QR codes and e-way bills, straight off the API-created invoice. Any currency, with conversion and forex gain or loss on settlement.
- 06
Delivery and webhooks
PDFs, email, payment links and a customer payment page from one call. Webhooks fire on creation, payment, overdue and status change, so nothing polls.
What changes once it is in
Ranges reported by clients running it, not laboratory figures. Where you land depends mostly on where you are starting from.
- Invoice generation reduced to one API call
- Data entry errors gone from the billing path
- Payment collection around 45% faster with instant invoices and links
- International customers billed in their own currency
- Billing disputes down around 60% on itemised transparency
- Recurring billing running unattended
