# How do I modify the auto-generated invoice number for the new financial year?

You can modify the auto-generated invoice number according to the new financial year in two ways:

*   [In the invoice creation page](/en-fr/books/kb/year-end-accounting/modify-autogenerate-invoice-number.html#In-the-invoice-creation-page)
*   [In the Transaction Number Series page](/en-fr/books/kb/year-end-accounting/modify-autogenerate-invoice-number.html#In-the-Transaction-Number-Series-page)

### In the invoice creation page

*   Go to **Invoices** on the left sidebar.
    
*   Click the **\+ New** in the top-right corner.
    
*   In the creation page, click the **Gear** icon next to the _Invoice#_ field.
    
    ![Generate Invoice Number](/books/kb/images/year-end-accounting/generate-invoice-number.png)
*   In the next pop-up, edit the **Prefix** of the invoice number based on the new financial year’s sequence. For instance, you can change the prefix from _INV23-xxxx_ to _INV24-xxxx_.
    
    ![Configure Invoice Preferences Pop-up](/books/kb/images/year-end-accounting/configure-invoice-number-preferences.png)
*   Click **Save**.
    

The invoice numbers for your future invoices will be automatically generated with the new prefix.

### In the Transaction Number Series page

*   Go to **Settings**.
    
*   In the _Customization_ tab, click **Transaction Number Series**
    
*   Click **Edit** in the top-right corner.  
    
    ![Edit Transaction Number Series](/books/kb/images/year-end-accounting/edit-transaction-number-series.png)
*   Edit the prefix in the _Invoice_ row.
    
    ![Edit Transaction Number Series](/books/kb/images/year-end-accounting/edit-transaction-number-series2.png)
*   Click **Save**.
    

The invoice number for your future invoices will be automatically generated with the new prefix.

Similarly, you can modify the transaction number prefix for all your sales and purchase transactions.
