Why a bookkeeper should be used to migrate your accounting software

Changing from one accounting software package to another one sounds straightforward when you read about doing it online. Maybe you have been using MYOB for years or your accountant has suggested you move to Xero or maybe your current system simply cannot keep up with what your business requires in terms of functions or processes.

The most common action business owners take is to switch to another platform in the hope that everything improves. 

What most business owners discover — often too late — is that migration is one of the more technically demanding things you can ask of an accounting software system and the gap between a clean migration and a messy one comes down almost entirely to who is managing the process and how well they prepare it.

This is why it is important to consider using a bookkeeper to do it for you & below I outline;

• What a migration from one accounting package to another actually involves.
• The specific problems that arise when it is done without professional oversight
• Why engaging a bookkeeper to lead the process is almost always the right decision.

Why should a business change accounting software packages

Before I explain about how to migrate, it is worth understanding why most  businesses switch accounting software at all. The reasons for switching actually shape how a migration should be approached and the most common triggers in 2026 are;

Moving from desktop to cloud. Many businesses are still running MYOB on a local server or a single desktop machine. As those businesses grow, employ more staff, or need their bookkeeper to access the system remotely, a cloud-based platform becomes necessary. 

Migrating from MYOB to Xero has become a strategic move for many Australian businesses seeking more flexibility, real-time financial visibility, and the ability for multiple users to collaborate from any location without sharing files or maintaining hardware costs. 

The previous bookkeeper or accountant used a different platform. When a business changes bookkeeper or accountant, the incoming professional may work primarily on a different system. Rather than maintain a platform the new advisor does not know well, it makes sense to migrate to their preferred environment.

The current platform no longer fits the business. Outdated systems, overly complicated software, or a collection of spreadsheets can lead to confusion, low productivity, and costly mistakes. By switching to a more modern platform, businesses can often solve accounting problems without as much external intervention. 

Cost or feature changes. Pricing restructures by MYOB or Xero — including Xero’s 2024 removal and 2026 reinstatement of payroll in its lower-tier plans — have prompted many businesses to reassess whether they are on the right platform for their needs and budget.

Regardless of the reason, every migration involves the same fundamental challenge: moving financial data that is structured one way in the old system into a new system that structures it differently — without losing accuracy, breaking compliance, or creating a set of books that does not reconcile.

What a migration actually requires

A migration between accounting platforms is not a copy-and-paste exercise. It’s important not to assume that MYOB and Xero are identical until it is too late, MYOB might handle business-critical processes that Xero cannot and vice versa. 

Understanding what is actually involved explains why the process requires professional management.

Step 1: Cleaning your data

If you have bookkeeping mistakes in MYOB, you will have bookkeeping mistakes in Xero. Migrating dirty data means your new file will contain dirty data and it will be even more difficult to identify the original source of the problem when you are travelling across two accounting systems to understand what happened. 

Before any migration begins, a bookkeeper must review the existing file and address outstanding issues. This includes writing off old uncollectable debts, removing duplicate suppliers and customers, resolving any transactions that are sitting in incorrect accounts, and critically, ensuring that every bank account is fully reconciled up to the migration date. Partial transfers are among the most common migration mistakes found in financial audits. If bank accounts are not reconciled before migration, balances will not match once moved. 

Think of it like moving house, you do not take clutter with you, and you certainly do not leave important documents behind. A bookkeeper preparing a client for migration will spend considerable time on this cleaning phase before a single piece of data is exported.

Step 2: Chart of accounts 

MYOB and Xero organise accounts differently. QuickBooks Online has its own structure. Reckon uses another. Tax codes in MYOB rarely match those in Xero on a one-to-one basis, and incorrect mapping is a top source of hidden migration mistakes that often appear only during tax lodgement. Every account in the old system must be mapped to its equivalent in the new system before any data is transferred. Where a direct equivalent does not exist, a decision must be made and that decision has consequences for how transactions are reported going forward.

The chart of accounts mapping also determines the structure of every financial report the business will produce in the new system. Getting it wrong at this stage means reports that are structurally incorrect from day one, and correcting them retroactively is significantly more time-consuming than getting them right before migration.

Step 3: Deciding what history is important

Not all historical data needs to move. When clients are under a time crunch, you will need to ensure you have time to prepare by sorting through existing accounts, cleaning up trial balances, and mapping the new system. Data mapping can be incredibly complex when companies have many accounts or the data structure differs significantly between systems. 

There are three common approaches to historical data in a migration. 

1. 1. The first is a full transaction history transfer which means every invoice, bill, payment, and journal entry from the old system is imported into the new one. This gives the business a complete picture in one place but takes longer, is more technically complex, and carries higher risk of data integrity problems.

   2. The second approach is a summary opening balances transfer where the closing balances from the old system become the opening balances in the new one, and historical detail stays in the archived file. This is faster and cleaner, but means historical transaction detail is only available by opening the old system.

   3. The third is a hybrid which is bringing across a defined period of open transactions, such as unpaid invoices and bills, and using summary balances for everything prior.

Which approach is appropriate depends on the business’s industry, its reporting requirements, how long it has been operating, and how important historical transaction detail is to its ongoing operations. This is a judgement call that requires understanding both the business and the platforms — not something a business owner can readily make without guidance.

Step 4: Payroll migration

Of all the components of a migration, payroll is the one most likely to cause compliance problems when not handled correctly. Payroll is often one of the trickiest parts of a migration, especially for businesses with multiple employees. Errors here can cause compliance issues, unhappy staff, and unnecessary rework. 

Employee records, tax file number declarations, pay categories, leave balances, year-to-date figures, superannuation fund details, and STP reporting settings all need to be correctly established in the new system before a single pay run is processed. A missed leave balance means an employee’s entitlements are wrong from the first day in the new system. An incorrectly mapped pay category means STP reporting to the ATO is wrong — and correcting STP submissions after the fact is a time-consuming process that requires formal amended reports.

Before migration, it is essential to audit existing data like the payroll file and employee records, review open pay runs and close out draft entries, verify employee pay details, tax codes, and super fund numbers, and clean up leave balances to avoid carryover errors. Running a parallel pay run in both systems as in processing one pay cycle in the old platform and the new one simultaneously, can help verify that the numbers match. 

This is the most reliable way to confirm that the payroll migration is accurate before going live.

Step 5: Post-migration verification

Once data migration is complete, it is important to test imported data for accuracy to ensure that everything was properly transferred and nothing was lost in the process. This means running trial balances, profit and loss statements, and balance sheets in both the old and new systems and comparing them line by line. 

Bank accounts must reconcile in the new system to the same position they reconciled to in the old system at the migration date. GST settings must produce the correct results on a test transaction before any real transactions are processed.

This verification phase is not optional. It is the point at which errors introduced during the migration as mismatched tax codes, incorrectly mapped accounts, missing opening balances can be caught and corrected. Skipping it means those errors enter live data and begin compounding immediately.

The Common problems

The specific issues that arise in a DIY migration or a poorly managed migration follow a predictable pattern:

• Opening balances that do not match. The most fundamental problem. If the opening balances in the new system do not reconcile to the closing balances in the old system, every financial report produced in the new system will be wrong — and the discrepancy will be invisible until a bookkeeper specifically looks for it.

• GST codes applied incorrectly. Tax codes in MYOB rarely match those in Xero one-to-one, and incorrect mapping is a top source of hidden migration mistakes that often appear only during tax lodgement. A business that has been correctly reporting GST for years can find that its first BAS in the new system is wrong simply because the tax codes were not mapped carefully during migration.

• Duplicate contacts and messy supplier or customer lists. Old suppliers, inactive customers, or outdated invoices cause chaos once imported into the new system. Incomplete contacts like missing email addresses, phone numbers, and ABNs that can break invoice validation in the new platform. 

• Payroll year-to-date figures that are wrong. If a migration occurs mid-financial year, the year-to-date payroll figures must be entered as opening balances in the new system. If these are wrong, the end-of-year STP finalisation will be incorrect, and every employee’s payment summary which flows directly to their tax return and will reflect the wrong amount.

• Historical data that cannot be reconciled. When a business migrates without bringing across sufficient history, or when the history that is brought across is not verified against the source, the new system’s reports cannot be traced back to support evidence. This becomes a problem in an ATO audit, when a BAS is challenged, or simply when the business owner asks a question about a transaction from 18 months ago.

MYOB, Xero, QuickBooks and Reckon – how each platform handles migrations

Migrating to Xero

Xero is the most common migration destination for Australian businesses in 2026. Xero currently offers a complimentary migration service for MYOB users that pulls in two years of data including transactions, suppliers, customers, employees, and items, with a turnaround of approximately 24 to 48 hours for standard files. 

This sounds convenient and for simple files it can be, but the automated tool does not clean your data before importing it, does not map tax codes intelligently, and does not verify that the opening balances reconcile after transfer. The tool moves data; a bookkeeper makes it accurate.

Before converting, businesses must ensure MYOB is set to the correct GST accounting basis, that accounts receivable, accounts payable, and GST accounts are not set up as bank accounts, and that all bank accounts are reconciled. Foreign currency files and MYOB Essentials files require manual conversion rather than automated tools. 

Migrating from Xero to MYOB

This direction of migration is less common but does occur, typically when a business finds that Xero’s payroll limitations or plan-based employee caps are no longer suitable as the business grows, or when a new bookkeeper or accountant works primarily in MYOB. 

MYOB offers an import function for chart of accounts and contacts, but historical transaction data requires either manual entry or a third-party conversion service. The cleaning and verification steps apply equally regardless of direction.

QuickBooks Online

Migrating to or from QuickBooks Online adds a layer of complexity because the platform has fewer Australian-specific migration tools than MYOB or Xero, and the practitioner community in Australia that works regularly with QuickBooks is smaller. Third-party services can convert QuickBooks Online files to Xero or Reckon, typically within three to five business days depending on complexity. 

For a business migrating away from QuickBooks to one of the more widely used Australian platforms, this is generally manageable, but it requires a bookkeeper who has experience working across both systems.

Reckon

Reckon is an Australian-developed platform with a loyal user base and a growing payroll product that is already confirmed as Payday Super ready for July 2026. Businesses migrating from older Reckon desktop products to Reckon’s cloud offering, or from Reckon to Xero or MYOB, can use third-party conversion services. As with all migrations, the quality of the data before migration determines the quality of the data after it.

Why a bookkeeper is the ideal choice for managing a migration

The case for having a bookkeeper manage a migration rather than attempting it as a business owner is straightforward.

• They know what to look for before the migration begins. A bookkeeper reviewing a file prior to migration will identify the unreconciled transactions, the duplicate contacts, the incorrectly coded historical entries, and the payroll discrepancies that will cause problems if they move to the new system uncorrected. A business owner reviewing the same file will likely not know what they are looking for.

• They understand both systems. Data migration consulting requires a deep understanding of the new and old software to facilitate a smooth transfer of data  including data structures, procedures, and all processes involved. A bookkeeper who works across MYOB, Xero, and other platforms regularly has the comparative knowledge to make mapping decisions that a single-platform user does not.

• They can advise on timing. The timing of a migration matters. Moving mid-financial year creates payroll year-to-date complications. Moving in the middle of a BAS period creates GST reconciliation challenges. Moving at year end avoids both but requires the new system to be ready before the new financial year begins. A bookkeeper advises on when to migrate based on the specific circumstances of the business and the compliance obligations on the immediate horizon.

• They verify the outcome. Once the migration is complete, a bookkeeper performs the reconciliation checks, runs the comparison reports, and confirms that the new system is producing accurate results before the business begins processing real transactions in it. This verification step is the difference between a migration that is done and a migration that is done correctly.

• They manage the transition period. For most businesses, there is a period immediately after migration during which the old system needs to remain accessible for reference, staff need to be familiar with the new system’s workflows, and the bookkeeper needs to be available to resolve issues as they arise. This transition management is part of what a bookkeeper provides and what a business owner managing their own migration simply cannot replicate.

So should you migrate from one accounting software to another?

Switching accounting software is not a decision to make lightly or a process to manage alone. 

The risks of inaccurate opening balances, broken GST reporting, incorrect payroll data, and an ATO compliance position that cannot be verified are very real, and they do not announce themselves immediately. They emerge gradually, in BAS discrepancies, in year-end reconciliation problems, and in audit questions that cannot be answered from the records in the new system.

A bookkeeper can manage the migration from start to finish which can include cleaning the data, mapping the accounts, verifying the payroll, confirming the balances, and supporting the transition thus eliminates many risks. 

The cost of professional migration management is modest compared to the cost of unwinding a migration that was not done correctly.

If you are considering a switch between accounting platforms, or if you have already switched and have doubts about the accuracy of the data that came across, the starting point is a conversation with a bookkeeper who has experience in both systems and a clear process for making sure the transition is clean.
