Everything an invoice needs, and nothing it does not.
These are the real application's screens; only the data is made up.

Every invoice at a glance
What is issued, paid and overdue, and the state of every invoice.

A web invoice with a QR payment
Your customer opens the invoice from the e-mail, pays a domestic one by its QR code, and you see that they saw it.
Every document you issue
Invoices, proformas with their follow-ups, tax documents for payments, corrective tax documents and settlement invoices. An issued document never changes.
VAT the way the law counts it
Payer, non-payer or identified person, reverse charge, OSS, prices with or without VAT, and rounding per line to the cent.

Customers checked as you type
A company ID is enough: ARES fills in the name and address, VIES and the unreliable-payer register check the VAT ID.
Foreign currencies
The ČNB rate for the date of the taxable supply, and the VAT recap in Czech crowns.
An API for your own systems
OAuth 2, webhooks with retries, and the same API our own products use.
Your team and your accountant
Roles by what each person does: owner, write and read, read only and accountant. Two-factor sign-in, and several companies under one sign-in.

Questions and answers
The answers come from the help centre, which also has the steps.
How many companies can one account have?
One account holds one set of billing details: one company, one company ID. The registry fills in the rest.
The whole guide: Create an accountHow are invoice numbers assigned?
A number is given when a document is issued, from the series of its type, with no gaps. Drafts have no number.
The whole guide: Number seriesHow does my customer get the invoice?
Every issued invoice has its own page your customer opens from the e-mail.
The whole guide: The web invoiceCan I change an issued invoice?
