Moving to Xero: The Migration Checklist

About this guide

Moving accounting systems is the kind of project that either takes three weeks or eats six months, and the difference is almost entirely in the preparation. This checklist is the one we work through with clients migrating to Xero from Pastel, Sage Business Cloud, QuickBooks or a spreadsheet.

It starts with the question most vendors skip: whether you should move at all. Then it covers choosing a conversion date that does not split a VAT period, the documents to have ready (trial balance, debtors and creditors age analyses, stock valuation, fixed asset register, the last VAT reconciliation), and designing a chart of accounts around how your business actually earns rather than copying the old one across.

There is a realistic timeline showing where the calendar time genuinely goes — bank feed approval, not data conversion — and the five mistakes we see most often, including the one that causes the most damage: converting without reconciling opening balances to your last signed financial statements.

What each section covers

First, should you move at all?

Switching accounting systems is disruptive, and it is not always the right call. Be honest with these before going further.

Choose the conversion date

The cleanest date is the first day of a new financial year. Everything before it stays in the old system, everything after starts fresh. · The second cleanest is the first day of a new VAT period, so no VAT return is split across two systems. · Never convert mid-VAT-period unless you enjoy reconciling two sets of figures for one return.

What to prepare before the switch

The clean-up is the real work. Converting a messy ledger produces a messy Xero file, and then everyone blames the software.

Design the chart of accounts around your business

The single biggest missed opportunity in a migration is copying the old chart of accounts across unchanged. This is the one moment where restructuring costs nothing.

Connecting the plumbing

Apply for bank feeds early — the bank's approval is usually the longest wait in the whole project · Confirm which accounts feed automatically and which need statement imports · Set up your VAT settings to match your SARS category and registration date

A realistic timeline

A straightforward small business is usually working entirely in Xero within two to three weeks of starting.

The five mistakes we see most

Converting without reconciling the opening balances to the last signed statements. Every later difference becomes impossible to trace. · Bringing across years of transaction history that nobody will ever open, which slows the file and adds cost. · Copying the old chart of accounts unchanged and losing the one chance to fix the reporting.
