# Changing the type and company on your invoice

When you create a sales invoice, the **'company' field is blocked** as soon as the invoice has a number. 
When you create an [incoming invoice](https://support.robaws.com/en/article/incoming-invoices-general-explanation-unv556/), the **'type' and 'company' fields are blocked** as soon as the invoice has a number. 

This is done because the numbering is determined by the journal, and the journal is tied to the invoice type and the company. 

## Pro forma or numbered invoice

To make sure these fields are no longer blocked and you can still change the type and the company, you can use [PRO FORMA invoices](https://support.robaws.com/en/article/creating-a-pro-forma-invoice-lt79wr/).

You set the use of a [PRO FORMA invoice](https://support.robaws.com/en/article/creating-a-pro-forma-invoice-lt79wr/) on the journal. To do so, go to **settings > general > journals.**
On a journal you have an **'automatic booking'** setting:

* **Activated**: we automatically add an invoice number to the invoice. In that case the 'type' and 'company' fields are blocked automatically
* **Deactivated**: we do not add an invoice number to the invoice yet. In that case you can change the 'type' and 'company' fields


![Function for using PRO FORMA](https://storage.crisp.chat/users/helpdesk/website/-/e/a/d/f/eadf6dec760ec000/schermafbeelding-2025-09-18-om_1wbtizs.png =500x359)


||| As soon as you book the invoice (via the 'book' action button), the invoice is given an invoice number based on the type and the company that have been set. After that these fields are blocked.

## What if I have an invoice with the wrong type/company?

**We cannot release the 'type' and 'company' fields for you**. Once the invoice has been created, we can no longer put this right.
In that case a **new invoice** always has to be created with the [PRO FORMA journal](https://support.robaws.com/en/article/creating-a-pro-forma-invoice-lt79wr/). 

Go through the **following steps**:

1. Go to **settings > general > journals** and change the journal to ['PRO FORMA'](https://support.robaws.com/en/article/creating-a-pro-forma-invoice-lt79wr/) or create a new ['PRO FORMA'](https://support.robaws.com/en/article/creating-a-pro-forma-invoice-lt79wr/) journal
2. Select the wrong invoice in the overview
3. Click the 'duplicate' action button at the top and choose the PRO FORMA journal
4. Delete the wrong invoice
5. Change the type on the new invoice to the correct one
6. Book this new invoice so that an invoice number is assigned (you do this via the 'book' action button)
