- QuickBooks Desktop, I started in a company this Jan of 2024, and came in as the Senior Accounting Manager, first cleaning up 2023 financials through QuickBooks Desktop Enterprise.

- The A/P dept merged some duplicate Credit Card Accounts together and lost years of all credit card reconciliations, from American Express C/C.

- These all had once been reconciled, and now back to 2015 to present are all gone.

I did need to reconcile 2023 for this new company I am at. I found out there were 2 to 3 different duplicate credit card accounts, with different varying transactions in each. I needed to take a moment to think what was best to be able to make move these 7 difference accounts back into the original 3 credit card accounts. Before decision was made, I just find out that those just were merged by the A/P Department. Now I see that all the reconciliations are lost back to 2015. I do not even have all the statements dating back to then.

The last known reconciliation that was correct was in September 2022 before the duplicates and merge. Can I actually enter the amount of that last known reconciliation and run it for all years past at the same time?

And if anything is different, can I adjust.? Or can I just restart from October of 20212, or just start a new from 2023, to complete for taxes?

One Big question I have is, what if there where duplicates in the other those accounts, as in you have 2 duplicate credit card accounts in QuickBooks, and then two of the same transactions where in both accounts, and this may have happened more than once, who do I fix this? 

Any suggestions are helpful!! I am waiting for more advice before I go the CFO and CEO to determine how we are going to go about fixing this, before I move forward with the rest of the 2023, cleanup/workup.
