Invitbox calls them “GL Codes”.
Xero knows them as the “Chart of Accounts”
Again, because of the connectivity between invitbox and Xero if you create or edit your Chart of Accounts in Xero you simply need to go to Admin > GL Codes in invitbox, click edit, then click Import from Xero.
When invitbox connects to Xero, invitbox will import all the GL Codes (Chart of Accounts) from Xero.
If you wish to reduce the number of GL Codes that invitbox presents to you on its drop down lists, go to Admin > GL Codes > edit and uncheck those that you do not want to have displayed.
