Catchup bookkeeping is a once-off project to get your accounts up to date and reconciled. It's usually done where the accounts have fallen behind, or there are problems in the accounts that need to be resolved to be financially accurate. Occasionally the trigger is wanting to get your tax returns done during tax season before you see your accountant. Sometimes it involves also catching up on BAS or other compliance reporting. Some people refer to catch up bookkeeping as a rescue or fix up - we like to think we're simply helping business owners get a clean set of books that they can move forward with, with confidence.
