At some stage you may want to change your bill numbers to a different or new range.
For AE sites, to determine what method has been used to set up your invoice numbers, you will need to check the configuration. Refer to Bill Sequencing > Adding configuration keys for Bill Sequencing by Company to determine if Bill Sequencing has been implemented.
AE Bill Sequencing can be used where you have multiple billing companies and want separate invoice numbers issued per company. It isn't necessary to set up Bill Sequencing where you have only 1 company set up in your database.
Automatic bill numbers are generated when the bill is posted.
