QuickBooks Online (QBO) depends on the data and how MMC Convert migrates it to the application, Kieran7.
To correct the report after migration, ensure that the VAT configuration in your current plan matches the requirements of your business.
Then, verify that all entries have been imported and categorized correctly.
After that, manually adjust any incorrect VAT-eligible transactions.
Once you've made the adjustments, generate the VAT report again to confirm that everything has been posted accurately.
Moving forward, you can file your VAT return and record VAT payments to avoid late returns and extra fees.
