# Invoice settings

Different settings and serial numbers can be assigned to different invoice issuers, buildings, and types.

### **SETTING UP INVOICE SERIAL NUMBERS:**

-   Open the **Invoices** module and select **Settings** in the top right corner.
-   Click **Add Rule** in the top right corner.
-   If you want the same invoice series to apply to all **building owners**, leave the field empty. If not, make every building owner their own rule.
-   Leave the **building** field empty if you want the same serial number to apply over all your buildings. If not, make every building their own rule. 
-   Leave the **Invoice Type** field empty if you want the same serial number to apply to both invoice types. Otherwise, select the appropriate type - rental or utility invoice. 

***NB!** If you create a rule only for rental invoices, you must add a separate rule for utility invoices.*

-   Select the invoice **language.**
-   Set the invoice **serial number.** For example, if you set it to 100, the first generated invoice will have this number.

***NB!** Without configuration, invoice numbering will always start at 1 by default.*

-   Invoice **number prefix** – add a prefix if needed, such as a letter combination.
-   **Comment** – add additional information to the invoice. Comments can be removed at any time.
-   Show **VAT on rows** – If enabled, VAT will be displayed for each cost. Otherwise, VAT will only be shown for the total amount.
-   Show **Reference Number** – displays the tenant’s reference number on the invoice. To add it, go to Contact Management > Select the tenant > Click Edit > Scroll down and fill in the Reference Number field > Save.
-   Generate **reference number from invoice number** – the reference number will be created based on the invoice number.
-   Show **contract number** – displays the tenant’s contract number on the invoice.
-   Show **row additional info** – displays room-specific details for each rental line item.
-   Show **building address** – displays the building address related to the invoice.
-   **Copy email(s)** – add email addresses if you want the invoice to be automatically sent to additional recipients.

Finally, **save** your settings. Create as many rules as needed.

**Important:** Modifying invoice settings does **not** affect existing (already generated) invoices. Changes apply only to new invoices. If you need to update existing invoices, delete them and generate new ones.
