Changing the serial number in your company file

Changing the serial number in your company file

There may be times when you need to change the serial number that’s recorded in your file to another number that’s registered to you. You might need to change it if:

  • someone created a file for you and used their own serial number to activate it (for example, your accountant).
  • you have more than one copy of AccountRight, and have subscribed using a different serial number to the one recorded in your file.
  • you just purchased a new copy of AccountRight (which includes a new serial number and subscription), but you were already using an AccountRight file.
    If you want to upload it online using a subscription that’s linked to another serial number, you’ll need to change the number that’s in your file.

To change your serial number, open your company file in AccountRight, go to the Help menu and choose Change Serial Number. You'll need internet access to complete the process.
