What are online invoices?
Online invoices are sales documents issued in a web browser, without installing any software on your computer. Your data stays in the cloud, so you can reach it from a laptop, tablet and phone — from anywhere.
Invoicing online instead of installing software
In the online version there is no installation, no updates and no moving the database between computers. You log in to the panel in your browser and issue an invoice in a matter of seconds — from the office, from home or from your phone on the way to a client.
All the documents you have issued, your contractors and your products sit in one place in the cloud, synchronised across devices. You can e-mail an invoice, download it as a PDF and pass it on to KSeF — without leaving your browser.

- VAT invoices and non-VAT invoices

Not just invoices — your whole sales process online
Invoicing is the last stage of a sale. In Mobilna Faktura you run the entire process online: you issue a quote, the client accepts it, you turn it into an order (ZK), and finally you create an invoice with a single click — without entering the line items again.
On the purchasing side you run supplier orders (ZD), while a simple CRM keeps the contact history for every contractor. Your whole sales funnel is online, available from any device.
