I’ll chime in on this thread to assist you further, gesenvsys.
Fiat Lux – ASIA is correct about utilizing an exporter tool to back up your QuickBooks Online (QBO) data. Since QBO India will no longer be supported and access in any form is unavailable after 30th April 2023. Exporting tool would be a great option.
Additionally, here is a helpful reference to learn more about the discontinuation: Discontinuation of QuickBooks in India. You can find information there if you want to switch to a new accounting or financial management system.
Please let me know if there is anything else you need assistance with, and I'll get back to you as soon as I can. Have a good one!
