Hi peteconway-outlo,

Thanks for posting in the Community! We have MMC Convert our data migration supplier that help us migrate customer data over from other accounting software programs.

You can check it here the list of software that can be converted to QuickBooks Online: https://www.mmcconvert.com/order-free-conversion-to-qbo-australia.

To give you an overview, here's how does the data migration process work.

1. Sign up for QuickBooks Online (if you haven't already, sign up either Essentials or Plus).
2. Get your existing file up to date.
3. Reset your QuickBooks Account (if required).
4. Place a conversion request.
5. Once the conversion is complete, review and approve your data.

For more detailed information, you can check this article: Frequently asked questions about bringing your data to QuickBooks Online

Let me know if you have any other questions, I'll be around to help. Have a nice day!
