Introduction
The invoices API exposes information related to expenses happening within the Perk platform. Any service booked within the platform is invoiced by Perk (merchant) to the selected invoice profile (legal entity). The service allows you to access both invoices and invoice lines, which can be used for for a wide range of use cases, from expense reporting to accounting.
An invoice represents the legal document issued by the merchant (Perk) to the buyer (Invoice Profile), indicating the services, quantities, and prices for fees and services booked within the platform.
Invoices contain invoice lines. Each line refers to any service added to the invoice, together with any quantities, unit price and taxes that pertain to them.
