02 — A useful first pass
01
Replace the sample inputs with one complete reporting period.
02
Keep every source on the same cut-off and write down each definition gap.
03

The toolkit is an illustrative operating aid, not accounting advice. Agree material definitions and decisions with your finance lead.
03 — If the numbers still disagree
Bring the unresolved bridge. We will compare notes.
