Xero Migration: A Step-by-Step Playbook and Common Pitfalls

If your books live across spreadsheets, legacy software, and email, migrating to Xero can be transformative. Real-time bank feeds, clean reporting, and smoother ATO interactions via Online Services for Business and SBR-enabled software make compliance and decision-making easier. Here’s a proven, low-risk migration plan designed for growing SMEs.

1) Define the Migration Scope

Decide what to bring across: chart of accounts, open AP/AR, bank recs, payroll YTD, inventory, and fixed assets. Confirm a cutover date (month-end works best) and freeze parallel processing during go-live.

2) Clean Before You Convert

Archive obsolete contacts, normalise tax codes, and reconcile bank accounts. This prevents duplication and GST miscodes from following you into Xero.

3) Build the COA & Tax Mapping

Set up a clear chart of accounts and map GST tax codes correctly, especially if you supply GST-free or input-taxed services. Proper tax mapping makes BAS preparation faster and reduces revision risks.

4) Payroll & STP Readiness

Ensure employee records, TFNs, super funds, and YTD balances are accurate. With Single Touch Payroll (STP), payroll data is reported to the ATO every pay run through STP-enabled software (such as Xero with compliant STP connectors).

5) Test, Then Go Live

Pilot a month’s transactions in a sandbox or small live segment. After cutting over, lock historical periods and run a tight first-month close, bank recs, supplier statements, and GST reviews.

6) Leverage SBR & ATO Online Services

Using SBR-enabled software and Online Services for Business streamlines lodgements, secure mail, and payment plans, reducing rekeying and error risk.

Common Pitfalls

  • Migrating messy data (duplicate contacts, wrong GST codes).
  • STP not configured correctly.
  • No month-end cadence post go-live.
  • Having a go without sufficient insight or experience.
