Invoicing
Bill every active subscription in one click.
Recurring invoices that never bill twice. Generate invoices for every due subscription with one click. Knock tracks what has been billed so the same period is never invoiced twice.
What it does
Invoicing in Knock
Knock turns active subscriptions into invoices on their due dates. Each run records the period it covers, so running billing twice, or clicking the button in a hurry, never produces a duplicate invoice.
How it works
Four steps
- 01
Find what is due
Knock checks every Active subscription whose next billing date has arrived.
- 02
Generate invoices
Lines, discounts and taxes are copied from the subscription and totalled.
- 03
Confirm and send
Invoices start as drafts. Confirm them and send them to the customer.
- 04
Advance the date
The next billing date moves forward by one plan interval, ready for the next cycle.
