Invoice template

A branded invoice with a colour header, itemised table and automatic totals and tax.

What it looks like

A bold header band with your business name, a summary row with the client, the due date and the amount due, then an itemised table with alternating row shading. Line amounts, subtotal, tax and total are calculated from quantity, unit price and tax rate, so the numbers always add up. Payment details and notes sit at the foot of the page.

Use it with your AI assistant

Connect Pressa to your assistant once, then ask for the document in plain words. It asks you for anything it is missing, fills the template and hands you the PDF. To change something later, just say what.
