HELP!!!!! upgraded my subscription from QBSE to simple start and my accounts/balances/invoices and transactions are all messed up and all over the place!!

Thanks for reaching out to us, Steven.

I would love to help you, but I just need bit more information about your concern. Can you tell me more what happened to your accounts, balances, invoices, and other transactions after migration?  Additionally, it would be greatly appreciated if you could provide a brief overview of the migration process you've undertaken.

With the additional context, I'll be able to  explore potential solutions to address your issues concerns. Please feel free to provide any further details or a screenshot that you think might be helpful in understanding your situation.
