Xero → Sage (Rare)

Only happens when outgrowing Xero’s inventory/payroll capabilities, or after acquisition by a Sage-using company.

Time: 6–10 hours (Sage import more complex)

Don’t migrate if: Happy with Xero, Sage works fine, or less than 1 year to business sale (keep existing system)

Consider instead: Adding specialist inventory tools on top of Xero (e.g., DEAR Inventory, Unleashed) — cheaper than full migration
