How to Switch Accounting Software Without Losing Your Data (or Your Mind)

Switching accounting software is one of those tasks that feels much harder than it actually is. The thought of moving years of financial data, reconnecting bank feeds, and learning a new system keeps a lot of business owners stuck on software they’ve outgrown — or software that’s outgrown them.

But the reality is that most migrations take a few hours of focused work, not weeks. And the cost of staying on the wrong platform — whether that’s rising subscription fees, lost productivity, or compliance headaches — almost always outweighs the short-term effort of switching.

Here’s how to do it properly.

When it’s time to switch

Not every frustration warrants a full migration. But there are clear signals that your current software has become a liability rather than an asset.

You’re paying significantly more than you were a year or two ago — for the same features. If your accounting software has hit you with repeated price increases without meaningful improvements, you’re subsidising someone else’s growth strategy. Some platforms have raised prices by 40% or more over just a few years, and that trend rarely reverses.

The interface has changed and your workflow is slower. Software updates should make things faster, not slower. If a recent redesign has added clicks, removed shortcuts, or broken processes that used to work smoothly, that’s a real productivity cost.

You’re paying for features you don’t use. Many platforms bundle features into expensive tiers. If you’re on a $70 or $90 per month plan but only use invoicing, bank feeds, and BAS reporting, you’re overpaying.

Support isn’t there when you need it. When something breaks — a bank feed stops working, a BAS calculation looks wrong — you need help quickly. If your current provider takes days to respond or hides behind chatbots, that’s a risk to your business.

If two or more of those sound familiar, it’s worth exploring your options. Our guide to choosing accounting software can help you evaluate what’s out there, and our comparison of Xero alternatives covers the main contenders for Australian businesses.

What data you need to migrate

You don’t need to move everything. In fact, trying to migrate your complete transaction history going back years is usually unnecessary and creates more problems than it solves. Here’s what actually matters.

Your chart of accounts. This is the backbone of your accounting structure — the categories and account codes you use to classify transactions. Export this from your current software and import it into the new one. Most platforms support CSV imports for this.

Contacts. Your customer and supplier list, including names, email addresses, payment terms, and any outstanding balances. You’ll need these for ongoing invoicing and bill management.

Outstanding invoices and bills. Anything that hasn’t been paid yet needs to be in the new system so you can track it to completion. Paid invoices from the past can stay in your old system — you don’t need them day-to-day.

Opening balances. This is the critical step most people worry about. You’ll need a balance sheet as at your switchover date showing account balances for all your asset, liability, and equity accounts. Your new software will have a way to enter these as opening balances. If you work with an accountant, this is the step to loop them in on.

Bank feed connections. You’ll set these up fresh in the new platform. Most Australian banks are supported by major accounting software, and connecting usually takes a few minutes per account.

Payroll data (if applicable). If you run payroll, you’ll need year-to-date figures for each employee — gross pay, tax withheld, super contributions, and leave balances. This matters for accurate reporting to the ATO, especially mid-financial year.

The step-by-step process

1. Pick your switchover date

The cleanest time to switch is at the start of a new financial year (1 July for most Australian businesses) or at the start of a new BAS quarter. This gives you a clean cutoff point and makes opening balances straightforward.

That said, you can switch at any time. It just means your opening balances need to be accurate as at whatever date you choose. A mid-quarter switch works fine — it’s just a bit more reconciliation work.

2. Export your data from the old system

Before you change anything, export everything you might need. Most accounting software lets you export your chart of accounts as CSV, your contact list as CSV, outstanding invoices and bills, a trial balance or balance sheet as at your switchover date, and a full transaction history (for reference, not necessarily for import).

Save these exports somewhere safe. Even if you don’t import everything into the new system, having the data on hand is important for reference and for your accountant.

3. Set up the new system

Create your account, configure your business details (ABN, GST registration, financial year), and import your chart of accounts. Then add your contacts — most platforms let you import these via CSV in bulk.

Spend some time getting the basics right before you start entering transactions. Set up your tax rates (if they’re not pre-configured for Australia), your invoice template, and your default payment terms. It’s easier to do this now than to fix it later.

4. Enter opening balances

This is the step that scares people, but it’s more methodical than difficult. Take the balance sheet from your switchover date and enter each account balance into the new system. Your new software will have a dedicated setup wizard or opening balance entry screen for this.

If the numbers don’t balance on first entry, don’t panic. Check for rounding differences, make sure you haven’t missed an account, and verify that debits and credits are on the correct side. If you’re unsure, your accountant can review this in twenty minutes.

5. Connect your bank feeds

Link your bank accounts in the new system. Transactions will start flowing in from the connection date. For the period between your switchover date and when the bank feed starts, you may need to import a bank statement manually (most platforms support this via CSV or OFX files).

6. Enter outstanding invoices and bills

Any unpaid invoices you’ve sent and any bills you haven’t yet paid need to be entered in the new system. This ensures your accounts receivable and accounts payable are accurate from day one.

You don’t need to re-enter every line item. Many businesses enter these as single-line summary entries with the correct total, due date, and contact. The detailed breakdown lives in your old system if you ever need it.

7. Run parallel for one BAS period

This is optional but strongly recommended, especially if you’re switching mid-financial year. Keep your old system accessible (most let you retain read-only access on a free or reduced plan) and run your new system as the primary for one full BAS quarter.

At the end of the quarter, compare your BAS figures between the two systems. They should match. If they don’t, you’ve got a clear window to find and fix the discrepancy before it becomes a bigger problem.

Common mistakes to avoid

Trying to import your entire history. It’s tempting but usually counterproductive. Historical transactions don’t reconcile cleanly across different software because account structures, tax treatments, and rounding rules differ. Use opening balances instead and keep your old system available for historical reference.

Not checking bank feed compatibility first. Before committing to a new platform, verify that your bank accounts are supported. Most major Australian banks work with most accounting software, but smaller banks, credit unions, or specialist accounts sometimes don’t.

Switching in the middle of a BAS period without a plan. If you switch mid-quarter without clear opening balances, your BAS figures will be wrong. Either time your switch to align with a quarter boundary or be very precise about your cutoff date and balances.

Forgetting about payroll year-to-date figures. If you switch payroll systems mid-financial year and don’t bring across year-to-date amounts, your PAYG summaries and super reporting will be wrong at EOFY. Get these numbers right from the start.

Not involving your accountant. If you work with an accountant or bookkeeper, tell them before you switch — not after. They’ll likely have preferences about chart of accounts structure, they can verify your opening balances, and they may need to set up their own access to your new platform. Most accountants have done this before and can save you time.

How long does it actually take?

For a typical small business — sole trader or small company with one or two bank accounts, a straightforward chart of accounts, and no payroll — the core migration can be done in an afternoon. Setting up the new system, importing contacts, entering opening balances, and connecting bank feeds takes two to four hours of focused work.

Businesses with employees, multiple bank accounts, or more complex structures should allow a full day, plus time for their accountant to review opening balances.

The ongoing adjustment period — getting used to the new interface, finding where things live, building new muscle memory — takes a week or two. After that, most people wonder why they didn’t switch sooner.

The cost of not switching

Here’s the thing people don’t calculate: the ongoing cost of staying on the wrong software.

If your current platform costs $70 per month and a better alternative costs $19 per month, that’s $612 saved in the first year alone. Over three years, it’s over $1,800 — and that assumes your current provider doesn’t raise prices again (they probably will).

But the bigger cost is the time. If a clunky interface adds ten minutes to your daily workflow, that’s over 40 hours a year spent fighting your software instead of running your business. Your time has a value, and it’s almost certainly more than zero.

Making the move

The best time to switch accounting software was before the last price increase. The second best time is now. The process is more straightforward than most people expect, and the tools available today — including Treldy — are designed to make migration as painless as possible.

If you’re on the fence, start by signing up for a free trial of the platform you’re considering. Spend an hour exploring the interface with real data. If it feels better than what you’re using now, the migration effort will pay for itself within weeks.

Your accounting software should be saving you time and money, not costing you both. If that’s no longer the case, it’s time to switch.
