Invoices
An invoice bills your customer for one period of an order: its lines, tax and totals, with every amount in integer minor units. Customers subscribed through Stripe Checkout are invoiced by Stripe, and those invoices are kept in sync from Stripe; everyone else is invoiced by Spondo Billing's billing run (for up to 90 days after an order ends, or after its end date last moved, anything still owed for it, such as usage sent late, comes on a true-up invoice of its own), which hands each invoice it posts to Stripe to collect when Stripe knows the customer (a hand-over cut short is finished within a minute or so). An invoice paid or voided in Spondo Billing stays so, whatever Stripe reports about it later. Every invoice Spondo Billing posts also has a hosted page your customer can open and print without signing in. You read invoices and their lines here, add your own metadata and purchase order reference, and settle them by allocating payments to their lines.
