How to issue an invoice with Firmify

When must I issue an invoice?

An invoice must be issued for every taxable supply — goods sold, service rendered, advance payment received. This is a requirement under Bulgarian VAT law and the Accounting Act.

Even if you are not VAT-registered, you still need to document your income. Firmify lets you issue invoices with 0% VAT.
