Find the Last Reliable Period
Ask which month was last completed and reconciled. A file containing transactions is not necessarily a file with accurate balances. Check statements, prior reports, and unresolved questions before choosing the starting date.
Make a list of the periods that need work and the accounts involved. That turns an undefined problem into a scope you can review.
Collect the Records for Every Missing Month
Gather complete bank and credit card statements, invoices, receipts, supplier bills, loan records, and processor reports where relevant. Save them by account and period. Record which documents are still missing so you can request them once, with a clear list.
Work Through the Backlog in Order
Review the oldest affected period first. Organize the activity, address missing or duplicate records, and reconcile the relevant accounts. Carry a reliable starting point into the next month rather than jumping between periods without resolving the earlier balances.
Keep questions together. A transaction list with dates, amounts, and short explanations is easier for an owner to answer than a collection of unrelated messages.
Review the Reports and Remaining Questions
Once a period is completed, review the reports for unusual amounts and missing context. Separate finished work from items awaiting records or a tax professional’s input. An unresolved question should have an owner and a next step.
Define the Work Before Hiring Help
A useful cleanup quote identifies the period covered, accounts, known issues, expected deliverables, and what documents you must provide. The condition of the records matters as much as the number of months.
For example, three months with complete statements and clear transactions may be more straightforward than one month with missing opening balances and duplicated activity.
Build a Monthly Routine Afterward
Decide how records will be collected, who answers questions, and when reports are reviewed. A modest routine followed every month is more useful than a complicated process nobody maintains. Lighthouse provides cleanup and ongoing bookkeeping for suitable clients nationwide.
