Invoices
Invoices in Enso are generated to bill your customers for products or services.Invoices can be created automatically or manually, and each invoice goes through a defined workflow before it is finalized.
How Invoices are Created
- Auto-generated: Invoices are automatically created when a contract is set up. All such invoices start in the Draft stage.
- Manual creation: You can also create invoices manually by navigating to Invoices > Create Invoice in the dashboard.

- Approved: Invoice is reviewed and approved.
- Raised: Invoice is finalized, assigned an invoice number, and the PDF is generated.
- Paid: Payment has been received.
- Cancelled: Invoice is voided.
- Credit Note Issued: A credit note has been issued against the invoice.
