System accounts can be set at the global level, but can be overwritten at the item, project, or invoice level, if needed. You can create and set your own default system, tax, and bank accounts in BQE CORE and then assign them in Settings. This helps you maintain your own Chart of Accounts numbering and hierarchy. CORE uses a combination of 5 digit-4 digit account numbers. Below is a list of System Accounts used in CORE.
