Invoice Types

Invoice Type identifies the type of fiscal document represented by an invoice record.

While most Kumusoft EFRIS API operations use dedicated endpoints for invoices, credit notes, and debit notes, invoice type values may still appear in API responses, reports, and legacy integrations.

Usage in Kumusoft API

Invoice type values may be returned when:

Querying invoice details

Retrieving invoice history

Generating reports

Working with legacy integrations

For new integrations, developers should use the appropriate endpoint:

Operation	Endpoint
Create Invoice	`/invoices`
Create Credit Note	`/credit-notes`
Create Debit Note	`/debit-notes`

Rather than selecting an invoice type manually.
