Accounting Software | Xero & QuickBooks Migration

Off Xero in weeks, not quarters. Validated before you commit.

Your COA, opening balances, vendors, customers, items and GST records move across with the trail intact. The validation runs before cutover, not after. Dual-run for a month so both ledgers agree before you switch off the old one. Nothing is written back to Xero or QuickBooks at any point.

Why leaving a cloud ledger is harder than it sounds

The data comes across easily. The agreement is the hard part.

Reading a Xero or QuickBooks file is not the problem. An API and a CSV export solve that in an afternoon. What takes the time is everything the export does not carry:

Opening balances tie to within a few dollars because of a journal someone posted and never reversed. Finding it takes longer than moving everything else.
The vendor and customer lists carry years of duplicates. Migrating them faithfully migrates the mess, and your auditor finds it at year end.
The COA grew one ledger at a time and was never mapped to anything, so nothing lines up with a filing until someone maps it.
GST records for filed periods are the part everyone assumes will come across, and the part that usually gets re-keyed.

The migration is not the risk. Cutting over on numbers nobody has reconciled is the risk, which is why the validation report comes before the date does.

What the migration tooling does

Capability, input, output.

Capability	Input	Output
Direct connection	Xero or QuickBooks, read-only authorisation	Sandbox load with the full ledger and transaction tree
COA migration	Existing COA across entities	Master COA mapped to SFRS and the ACRA XBRL taxonomy
Opening balance validator	Trial balance plus open journals	Variance report with per-ledger drill-down
Master deduplication	Vendor, customer and item lists across entities	Merged set, legacy IDs retained, merge audit trail kept
GST record migration	Filed GST returns and their supporting records	Imported into the GST register, period-locked
Multi-currency history	Foreign-currency balances and their rates	Balances carried with the rate that produced them, not re-translated
Dual-run reconciliation	Postings in both systems, daily	Daily variance report at the line level
Cutover and rollback	Both systems at cutover	Signed cutover plan plus a rollback runbook

Compliance + integrations

A migration that respects the year your auditor already signed.

Nothing is written back to your existing ledger at any point. Nothing posts to OneFinOps without validation. The migration itself is captured as a tracked event with the same audit-trail rigour that applies to ongoing accounting.

Regulations we work within

Companies Act 1967

Books of account preserved for the statutory period. The old ledger is kept read-only after cutover as the historical reference.
GST Act

GST records retained for the statutory period. Filed periods import locked, so a migrated return cannot be edited into a different one.
Audit trail

Edit log captured from day one, with the cutover itself recorded as a tracked event.

Xero & QuickBooks Migration FAQ

What buyers ask.

How long does it actually take?

For a single entity with a clean COA and up to two years of history, two to three weeks including the dual-run. Groups with several entities, a financial year that does not align across them, or a COA nobody has tidied in five years, run longer. The validation report at the end of the first week tells you which one you are, and we do not quote a date before it lands.

Do we have to stop using Xero during the migration?

No. It stays live throughout. The migration reads from it and never writes to it. During the dual-run both systems are posted in parallel and reconciled daily, and you only stop using the old one on the cutover date.

Do we have to keep paying for Xero afterwards?

That is your call, and plenty of teams keep it. Some run OneFinOps for AP, AR, procurement and close while Xero stays the statutory ledger, which the connector supports both ways. Others cut over fully. The migration does not force the decision, and it is reversible for the first month either way.

We are mid-year. Migrate now or wait?

You can migrate mid-year. The opening balance comes from the last closed month, and everything before it moves across as history. GST filing continues uninterrupted, since the filed periods import locked. Most teams that go mid-year pick a quarter boundary so the first full quarter in the new system is clean.

Our auditor signed last year in Xero. Does that follow?

Yes. The sign-off, the audit notes and the supporting evidence import as evidence against the migrated period, and that year stays locked in OneFinOps with the same evidence attached. Your auditor keeps their reviewer access.
