This article explains how you can create and send an electronic self-billing invoice (UBL) in Billit in three easy steps.
You can add a self-bill by clicking + Self-bill in the submenu 'Invoices' from the 'Expenditure' menu. Activate self-billing via Settings - Self-billing first!
If you want to import an existing self-bill (this may be an old invoice or an invoice you created in different software), you can complete the details during the import in fast input. After saving, the self-bill appears in the 'Expenditure' list.
