NAB Bookkeeper Closed: What Former Users Should Check

• Tax
• Small Business
• Accounting

NAB Bookkeeper is no longer available beyond April 2026. If you previously used it, the practical job now is to confirm that your historical records remain accessible, choose a replacement workflow, reconnect eligible bank accounts and make sure BAS work continues from complete records.

Thriday’s NAB Bookkeeper transition page

explains that the automated bookkeeping, tax and BAS features provided through NAB Bookkeeper have ceased. Former users may be able to continue with Thriday Accounting under a different service arrangement or move their bookkeeping elsewhere.

Treat the closure as a records handover, not only a software switch. Preserve the old evidence, reconcile the cutover date and confirm who will handle the next BAS before relying on a new system.

Quick answer

Former NAB Bookkeeper users should check four things first:

1. Which historical invoices, receipts, BAS records and reports they can still retrieve.
2. Whether the old bookkeeping period is reconciled to the bank.
3. Which balances and open transactions need to move into the replacement system.
4. Whether their accountant or BAS agent needs access before the next reporting deadline.

Gimbla is one replacement option for Australian small businesses. Its free Starter plan covers core accounting records, while the Plus plan adds features such as connected bank accounts and Australian BAS lodgment. Compare the current features and pricing against the work your business actually needs.

Key points

• NAB Bookkeeper’s April 2026 closure has passed, so migration language should now focus on record continuity.
• Keep source documents and tax evidence even if a software account is no longer active.
• Reconcile the final period before carrying balances into another accounting system.
• Compare bank feeds, invoicing, bills, GST, BAS, reports, data export and adviser access.
• A free plan is not useful if it cannot support the records your business needs.

Records to preserve after the closure

Do not assume a replacement platform will automatically contain every record from the old service. Gather what is still available from your files, adviser or former provider, including:

• customer and supplier details
• sales invoices, credit notes and payment records
• supplier bills, receipts and expense support
• bank statements and reconciliation reports
• GST and BAS working papers, lodged statements and ATO receipts
• chart of accounts and tax-code settings
• trial balance, Profit and Loss and balance sheet reports
• unpaid invoices, unpaid bills and other opening balances
• notes about assets, loans, owner drawings and unusual transactions

Australian businesses generally need to keep records that explain their transactions and tax position. If something is missing, ask your accountant or BAS agent what can be reconstructed before entering opening balances in a new system.

Choose a clean cutover date

A clear cutover date reduces duplicates and gaps. Many businesses choose the end of a month or BAS period, but the right date depends on how complete the records are.

Before the cutover:

1. Reconcile the old bank balance to the statement.
2. Review open customer invoices and supplier bills.
3. Save the final trial balance and key financial reports.
4. Confirm GST and BAS amounts still agree with the supporting transactions.
5. Record which items will be imported and which will be entered as opening balances.
6. Keep a copy of the old-to-new account mapping for your adviser.

The switching to Gimbla guide explains the local opening-balance workflow. Use it with accountant advice rather than treating migration as a simple data upload.

What to compare in a replacement

Start with the work that NAB Bookkeeper used to support, then test the replacement against your actual business:

• Can you create and retrieve invoices, bills, receipts and credit notes?
• Can you reconcile the bank without losing the source transaction?
• Does the software support Australian GST records and the reports behind a BAS?
• Can your accountant or bookkeeper review the file?
• Can you export reports and business data if you move again?
• Are bank feeds available for your bank, plan and business location?
• Which features are free, paid or subject to usage limits?

Do not choose only on the headline subscription price. A cheaper system can cost more in clean-up if it separates bank activity, tax records and financial reports.

How Gimbla fits

Gimbla’s free accounting software uses a free Starter plan rather than a 14-day trial. It supports core workflows such as invoices, bills, receipts, payments, bank reconciliation, GST tracking and financial reports.

For businesses that need more, the Plus plan includes connected bank accounts and Australian BAS workflows. The bank feeds page lists NAB alongside other supported Australian banks, while the BAS lodgment page explains direct lodgment through Gimbla. Check current plan limits and availability before deciding that the workflow fits.

Gimbla can organise the accounting trail, but it does not replace a registered tax or BAS agent. The business remains responsible for the accuracy of its records and lodgments.

Frequently asked questions

Is NAB Bookkeeper still available?

No. Thriday’s transition page says NAB Bookkeeper is no longer available beyond April 2026.

Can Gimbla connect to NAB bank accounts?

Gimbla’s bank feeds page lists NAB among the supported Australian banks. Check the current pricing and bank feeds pages for plan limits and availability.

Does Gimbla offer a 14-day trial?

Gimbla’s Starter plan is free rather than a time-limited trial. Businesses can move to Plus when they need paid features such as bank feeds or BAS lodgment.

Does Gimbla provide tax or BAS agent advice?

No. Gimbla provides accounting software and a lodgment platform. The business remains responsible for its records and filings and should use a registered adviser when needed.

In short

NAB Bookkeeper’s closure is now a record-continuity task. Preserve the old evidence, reconcile the final period, choose a cutover date and make sure the next BAS can be supported from complete records.

If Gimbla is on the shortlist, start with the free Starter plan and move to Plus only when the business needs bank feeds, BAS lodgment or other paid features.
