Load your balances as at the cut-over date, and confirm they balance before posting.

Opening balances set where each account stands on the day you start using AXO. They come from a trial balance exported from your old system as at your cut-over date.

Export a trial balance as at your cut-over date.
Import it in the Migration Centre.
Read the opening trial balance in the preview: total debits, total credits and the difference.
If the difference isn't zero, fix the file. AXO won't post opening balances that don't balance.
Confirm. The balances arrive as a draft batch.
Post the batch when you're satisfied.

Important

AXO checks the difference to the last decimal place. A tiny difference that rounding would hide is shown, not ignored.

Note

Cutting over at the end of your financial year keeps things simplest, because your income and expense accounts start the new year from zero.
