Reset invoice number

Hi,

There is no such functionality currently to reset invoice number but if this is the required thing for you then you can try following first on your staging(strictly recommended) and if it works fine then on live.

You need to enable WPI>Settings>Misc>Sequential Invoice Numbers first. The setting Sequential Starting Number field value will work only if it is greater than the last invoice number but in your case you want to start from 1 which will be not greater than last invoice number. So just set value 1 there and as we are storing last invoice number value in options table you can either change it directly from the Database or by running the

update_option( 'wpinv_last_invoice_number', 0 );

function single time. This will reset the invoice number to 0.

If you want us to update the things then let me know the admin and Cpanel details in private reply and we will look into this.

Let me know if you have any questions.

Regards,
Patrik
