AllDone compares last year's signed accounts, line by line, with the prior-year column of this year's trial balance mapped to the same lines. Where a line does not agree, a card names the line, both figures and the difference, lists the accounts sitting on it and the accounts that could move onto it. You choose one of three answers.

A gap smaller than rounding never becomes a card at all. Where the evidence decides it, one answer is starred with the reason it was chosen, either because last year's own figures place that account on that line or because moving it makes the line agree to the pound.

Last year's signed accounts are treated as the authority on where each account sat. AllDone builds one placement map for the job: a recorded answer wins, then a placement applied on this run, then the mapped statement line, then the section's own figures, which move an account only where the line then agrees to the pound. Where the figures nearly fit but not quite, that becomes the card's suggestion rather than a silent move, and an account is never moved between the balance sheet and the profit and loss on its own.

Two checks sit earlier: the opening trial balance against the signed accounts, section by section, and the uploaded reports against the signed accounts. Each offers accepting the comparative, adjusting the opening balance, or querying it with the client. Every blocker carries an answer you can record, so the job is never stuck.
