# Income

> How invoices enter Penzum

Your income can enter Penzum in three ways.

## Automatic Sync (recommended)

### NAV Online Invoice

Connect Penzum to the Hungarian tax authority's NAV Online Invoice system to automatically sync all your registered outgoing invoices — regardless of which invoicing software you use.

* [Connect NAV Online Invoice →](/en/nav)

### Számlázz.hu and Billingo

If you use Számlázz.hu or Billingo, connect your account to sync issued invoices automatically.

* [Connect Számlázz.hu →](/en/szamlazzhu)
* [Connect Billingo →](/en/billingo)

## Manual Entry

Invoices can also be added manually via **Income → New Invoice**. Enter the net amount, issue date, and payment date.

* [Manual invoice entry →](/en/manual-invoice)

## Bank Import *(coming soon)*

When your bank account is connected, incoming payments will also appear as transactions that can be linked to invoices. This feature is coming soon.
