What are Xero migration services and why do they matter?

TL;DR: what Xero migration services are

One-sentence definition

Xero migration services are professional conversion offerings that gather exported files from your current accounting system, map and import those files into a Xero organisation, and complete essential configuration so accounting, BAS and payroll processes continue without disruption. For official guidance from Xero see Convert to Xero for Australia and the Xero migration service overview.

Quick when-to-hire summary

If your business runs regular payroll with Single Touch Payroll (STP), has ongoing BAS/GST reporting, a complex chart of accounts, or multi-year records you must retain, a paid migration service or an experienced accounting partner usually reduces risk and saves time. Very small businesses with only a few recent invoices and a simple ledger can often use self-service imports. For Xero’s conversion options, consult Convert to Xero for Australia and the migration service details.

What Xero migration services typically include

Data types usually migrated

Common migration scopes import the chart of accounts, opening balances, contacts and contact balances, outstanding invoices and bills, bank statement history, and payroll exports needed to maintain STP continuity. Xero documents the file exports and data formats that support partner or Xero imports, so preparing correct exports is a critical early step.

What is not migrated or needs manual setup

Certain items frequently require manual recreation or a configuration review after import. Examples include custom reports, bespoke invoice templates, some historical attachments depending on your source software, and app integrations or automation rules. Xero’s migration guidance names these limits so you can plan which items to recreate or validate post-import.

Common post-migration configuration tasks

• Reconcile bank accounts and verify opening balances against source records.
• Set up payment services, invoice templates and branding.
• Reconfigure payroll settings for STP, including pay items and employee details.
• Reconnect bank feeds and third-party integrations.
• Run BAS and payroll continuity checks to confirm ATO reporting alignment.

Essential Xero migration export checklist (what to prepare)

Chart of accounts and opening balances

Provide an export of the chart of accounts and a ledger of opening balances for the conversion date. Xero requires clear mapping between old account codes and Xero accounts so opening balances import correctly. See Xero’s export guidance for the exact file types and formatting required.

Contacts and outstanding invoices

Export a contacts list with current balances, customer invoices that remain unpaid, supplier bills and credit notes. Carrying forward receivables and payables preserves cashflow reporting and reduces reconciliation work after cutover.

Historical GST and BAS data

Gather BAS and GST reporting history, prior BAS lodgements if available, and supporting transaction detail that evidences GST activity. Including this material helps validate GST positions at cutover and supports correct BAS lodgements going forward.

Payroll and STP files

Export payroll registers, pay item definitions, employee master files and any historical STP submission files you hold. Accurate payroll exports are essential to avoid gaps in PAYG withholding and STP reporting when you switch systems. Xero Central lists the recommended payroll exports for a clean conversion.

Bank and transaction history

Provide bank statement history and reconciled transaction exports up to your chosen conversion date. This enables a full reconciliation and helps avoid duplication or missing transactions after cutover.

Migration options: Xero service, certified partner, or DIY imports

Official Xero migration service

Xero offers an official migration service and partner conversion tools to import prepared exports into a new Xero organisation. This option suits clients who prefer Xero’s own conversion team to run the import. Xero Central explains eligibility, required exports and how Partner Central supports the process.

Migration via an accounting partner or integrator

Certified Xero partners, accountants and integration specialists perform conversions using partner tools and bespoke workflows. A local accounting partner can combine the conversion with onboarding tasks such as payroll and BAS setup, reconciliations and a hands-on walkthrough. If you want local support in Parramatta or Liverpool for BAS, STP and ongoing bookkeeping, look for a firm that lists Xero among its cloud partnerships.

Self-service imports and third-party converters

For simple record sets, Xero supports self-service CSV imports for contacts, accounts, inventory and transactions. Third-party converter apps can move larger datasets. Self-service is low cost and fast, but it requires careful formatting and is not always suitable for complex payroll or multi-period BAS histories.

How migration affects BAS, STP and year-end reporting

BAS and GST continuity checks

When you move to Xero you must confirm GST and BAS continuity. That includes reconciling GST as at the conversion date and ensuring opening balances reflect net taxable positions. If GST history is incomplete, you risk incorrect BAS lodgements. Use exported BAS history and reconciliation results after import to validate GST figures against prior ATO filings.

STP payroll data reconciliation

STP requires continuous PAYG withholding records, so missing payroll history can cause reporting gaps and mismatches. Include payroll registers and prior STP files in migration exports and reconcile year-to-date wages and tax after cutover. A payroll-savvy partner can help avoid missed submissions or duplicate STP events.

Year-end reconciliations and notes

After migration, complete year-end reconciliations and prepare notes that explain any adjustments introduced during conversion. This keeps year-end financial statements auditable and allows your accountant or auditor to reconcile balances to source documents. If you expect to lodge company or trust tax returns soon after conversion, coordinate timing with your tax advisor to avoid complications.

Timeline, common risks and what to expect during migration

Typical migration phases

• Discovery and scoping, including a file list and agreed conversion date.
• Export and handover of source files from the client.
• Test import and validation in a sandbox or copy of the target file.
• Cutover to Xero on the agreed date, followed by reconciliations and final configuration.
• Post-migration support and training for staff who use Xero day to day.

Top client objections and answers

• Downtime concerns: migrations are typically staged to limit disruption and are often completed outside trading hours.
• Data loss worries: prepare backups and perform a test import to verify results before final cutover.
• Hidden costs: agree scope and deliverables in writing so post-migration tasks are priced transparently.

Reconciliation and validation steps after cutover

Immediately reconcile bank balances, outstanding invoices, BAS figures and payroll year-to-date totals. Ask your migration partner or accountant for a short independent review to certify that key balances match source reports.

How to decide whether to hire a professional for Xero migration

Decision checklist

• Hire a partner if you have regular STP reporting, complex payroll, or prior BAS issues.
• A DIY import may be adequate if you have simple, recent transactions and a one-person finance function.
• Choose a local accounting firm that supports Xero if you want them to configure ongoing bookkeeping, BAS lodgement and STP.

Red flags that require a partner

• Multi-entity consolidation, trusts or a complex chart of accounts.
• Unreconciled bank accounts or unresolved BAS audit items.
• High payroll complexity including many pay items or historical STP gaps.

Frequently asked questions

How long does a Xero migration typically take for a small business?

Time varies with complexity. Small, simple files may be converted in a few days once exports are ready. More complex migrations that include payroll, multiple bank accounts and historical BAS reconciliation take longer because they require test imports and validation. The exact timeline should be scoped before work begins.

What types of data cannot be migrated and must be re-created manually?

Custom reports, some invoice templates, and certain third-party integration settings commonly require manual recreation. Historical attachments may not always import depending on the export format. Xero’s migration guidance outlines which items need manual setup after an import.

Will moving to Xero disrupt BAS lodgements or Single Touch Payroll reporting?

Not if migration is planned carefully. Include payroll exports and prior STP files in the migration, reconcile year-to-date totals after cutover, and schedule the conversion outside critical lodgement windows. A migration partner can help maintain BAS and STP continuity during the switch.

Should I import all historical transactions or start fresh with opening balances?

That depends on your needs. Importing full transaction history preserves audit trails and helps with long-term reporting, but it increases conversion effort. Starting with verified opening balances is a common approach when historical detail is not needed day to day. Discuss the trade-offs with your advisor.

What information should I bring to my first migration consultation?

Bring export files for chart of accounts, contacts, outstanding invoices and bills, bank statements to your chosen cutover date, payroll registers and any STP submission records. A partner will use these files to scope the conversion and produce an accurate plan.
