Bills

A bill represents an amount owed for goods and services provided by a vendor.

In the bill, you can add bill line items to record details about individual goods or services. In addition, you can add invoice information for associating the bill with an invoice.

Use POST /v3/bills to create a bill. You can also use POST /v3/bills/bulk to create multiple bills with one request. See the /v3/bills API for more information about the complete list of bill operations.

Creating multiple bills

You can use POST /v3/bills/bulk to create multiple bills with one API request.

Bulk bill creation at BILL follows a set of rules.

Successful response: In your bulk bill creation request, all your bills must be successfully created for a successful response. If any bill creation is not successful, the entire request fails and none of the bills in the request are created.
You can create bills for multiple vendors: You can create bills for one vendor or for multiple vendors with one POST /v3/bills/bulk request.

See the /v3/bills/bulk API for more information.
