What to provide

Approved opening balance/date, older transaction export, statement cutoff and accountant instructions.

How it works

  1. Read what the opening balance summarizes and which earlier rows are already represented.
  2. Place older rows on a timeline and separate overlap from genuinely missing history.
  3. Calculate a diagnostic overlap only with evidenced membership; never adjust the opening balance automatically.
  4. Return affected rows and accountant questions; do not import, delete, reconcile or post transactions.

The output

opening basis | older row/date | included evidence | possible overlap | diagnostic amount | question

Worked fictional example

Fictional opening 100 already includes a prior deposit 20. Adding that deposit again makes diagnostic 120; flag 20 potential double count, not an approved balance change.
