Backlog Bookkeeping From Bank Statements

I need help get my records back to date following a divorce. I can supply complete bank statements in FIVE different accounts, with money coming in and out as well as transfers FROM one of these FIVE accounts to the other 4 plus 4 other basic accounts, and I want every transaction entered, categorised, and above all I need to know how much money was transferred from one account to another as a total, how much money was supplied to certain suppliers, and how much money was spent. Please build the ledgers in whichever professional tool you prefer—QuickBooks, Xero, Wave, or a clean spreadsheet that shows the flow of money are all fine with me—as long as the final file can be handed over and opened on my end without extra cost. Accuracy and a clear audit trail are essential; transactions should tie back to the original statement balances. Additionally, I would like detailed interrogation of the financial data. This includes showing how much money moved between specific accounts (e.g., Account A to Account B), total income, total expenses, categorized expense ledgers, and all data compiled into a master Excel file. Deliverables: • Clean, reconciled books covering the entire backlog period • Summary of how much money went in TOTAL, how much money left (e.g., Account 2 to Account 3), etc. • Categorized expense ledgers • Master Excel file containing all data
