Invoicing isn't hard.
Finding the time to do it is.

Today you've been at the warehouse, visited a client, or met with a supplier. You get to the end of the day and the last thing you want is to search for invoices among messages, match numbers, fill in details and register them in software. You didn't start a business to spend your time on this.

Naia handles it for you. Forward an invoice to its chat with a couple of taps, let your suppliers send emails to it, or give it a quick WhatsApp instruction. Minimal mental load so you can focus on your business while admin takes care of itself.

How Naia works

No software to learn.
Tell it what you need. Naia understands what to do.

01

Understands intent

Naia interprets the message, document, and context. It knows whether you want to register a received invoice, issue a new one, modify a draft, or prepare a report.

When you register an invoice, Naia automatically calculates the correct tax treatment. Without you knowing what reverse charge means.

What your accountant does for you at quarter-end, Naia does with every invoice.
