The point of the cleanup
Bring forward what still makes sense.
The goal is to agree what should carry forward, what can be simplified, and what useful detail should still be preserved in the new Xero organization.
Simplify the chart of accounts
Old charts of accounts often collect duplicate, outdated or overly detailed accounts over time. During the conversion, selected accounts can be combined, renamed or renumbered while preserving useful distinctions where needed.
Add tracking where it helps
Tracking can sometimes be created from reliable information already present in the source, such as departments, locations, source account codes or other useful distinctions. This can preserve information from old accounts even when those accounts are combined or retired in the new structure.
Agree the new structure before the move
You decide what should be combined, renamed, renumbered or tracked before the conversion is finalized, so the move is built around the structure you have agreed.
