Accounts Payable

Retrieve and create bills using the Accounting API

Accounts payable

In Codat's API a Bill represents an invoice from a supplier, for this use case bills can be retrieved from the Accounting API, or you can create bills within your platform and post them to your customers accounting software.

Managing suppliers

In the accounting API a supplier represents a business or sole trader that provides goods or services to a company.

Suppliers are relevant for the bill pay use case as each bill is associated to a supplier - suppliers also have important information such as addresses and contact details which could be used to notify a supplier once a payment is made.
