## Issuing Invoices from Intum in Fakturownia

With the Fakturownia integration enabled, you can issue a new invoice from Intum with a single click - it will open in Fakturownia with the client's data already filled in. No need to enter the Tax ID, address, and contact details a second time.

### Prerequisites

You need to have the [Fakturownia.pl Integration](../integracje/integracja-z-fakturownia-pl) configured - that is, the app installed from **Account > Integrations & Add-ons** with at least one Fakturownia account added.

If you haven't done this yet - start with that guide and come back here after enabling the integration.

### Enabling

1. Go to **Sales > Settings** (or **Account Settings > Sales**)
2. In the "Invoicing" section, check **Create invoices via Fakturownia**

From this point on, the **New Invoice** button in the Sales module shows a list of connected Fakturownia accounts. You select an account and the new invoice form opens in Fakturownia.

### Issuing from the Client Card

If you click **Add Invoice** from the + menu on a client card, the buyer's data (name, Tax ID, address, email, phone) will be automatically filled in. You only need to add line items and issue the invoice.

### Multiple Fakturownia Accounts

When you have more than one account connected in the integration (e.g., separate accounts for domestic and international invoices, or for different companies), you'll see a list when issuing an invoice and can select the appropriate one.
