If you don’t use Számlázz.hu or Billingo, or if you simply have a one-off invoice to record, you can add invoices manually at any time. Manual invoices go through the same Pending → Paid workflow as synced invoices and appear in the same Income view — there’s no separate section or second-class treatment for them.
Add a New Invoice
Go to Income
Click Income in the Penzum sidebar to open your income list.
Click New Invoice
Click the New Invoice button in the top-right corner of the Income page.
Fill in the invoice details
Complete the following fields in the form:| Field | What to enter |
|---|
| Client name | The name of the client or company being invoiced. |
| Net amount (HUF) | The net value of the invoice in Hungarian forints, excluding VAT. |
| Issue date | The date the invoice was issued. |
| Payment due date | The deadline by which the client must pay. |
Save the invoice
Click Save. The invoice is created with a Pending status, meaning it has been issued but payment has not yet been received.
Mark an Invoice as Paid
When you receive payment from your client, you need to mark the invoice as Paid in Penzum so it counts toward your income summary and tax estimate.
Select the invoice
In the Income list, click the invoice you want to update.
Click Paid
Click the Paid button in the invoice detail panel. The status updates immediately.
An invoice in Pending status does not count toward your income total or tax estimate. Always mark an invoice as Paid as soon as you confirm payment — otherwise your tax calculation will understate your income.
Using Manual and Synced Invoices Together
You don’t have to choose one method exclusively. If you connect Számlázz.hu or Billingo later, or already have one connected, manual invoices and synced invoices coexist in the same Income view without any conflict. Penzum handles both types together in the income summary and tax estimate.
A common pattern is to connect your invoicing software for regular client work and add the occasional one-off or cash invoice manually — both will be counted correctly once marked as Paid.
