Create invoices

How to create and push invoices or bills to customer accounting platforms using the Merge Accounting API.

---

You have already followed the "Sync Customers or Suppliers" use case to ensure the contacts across your database and your customer's accounting system are in sync.

You'll have to specify a general ledger Account or Item on each line item of the Invoice/Bill. We suggest keeping this data in sync by storing the data in the GET /accounts and GET /items endpoints.

Identify when to send bills or invoices to your customer's accounting platform. This could be a button or form within your app's frontend or event-based logic.

Submit a POST /invoice request to create the Bill or Invoice in your customer's Accounting platform.

Your customers automatically will be able to receive invoices in their chosen accounting platform!
