Who changed what

Every entry keeps a record of who made it, who changed it and when, and that record cannot be edited.

Open any document and read its history. An auditor can see every change made in the year in one list.

Also in your numbers

Set a budget, see each month against it, and where the year is likely to land.

Several businesses rolled into one set of statements, with dealings between them taken out.

Tag income and spending by branch, project or department and read a profit for each.

Machines, vehicles and computers kept as a register, with depreciation worked out each year.

For the accountant: any entry by hand, checked to balance before it posts.

Income earned but not billed and costs owed but not received are booked, so each month tells the truth.
