What's The Difference?

Not All Messy Books Need the Same Fix

Bookkeeping clean up focuses on cleaning and reconciling transactions so your day-to-day books and reports are accurate.

Historical accounting clean up applies when prior-period balances need accounting-level corrections so your financials roll forward correctly.

Historical accounting clean up services

The real problem is in your history.

Historical accounting clean up services apply when the problem goes deeper than messy transactions usually when prior-period balances don’t make sense, roll forward incorrectly, or require accounting-level corrections.

Identifying the Problem

This can involve identifying which periods are impacted, isolating what's driving the mismatch (for example, timing issues or balance sheet items recorded inconsistently), and creating a clear path to correct the history so your financials are coherent and comparable period to period.

Which Service Do You Need?

In most cases it's one or the other: if your issue is mainly transaction hygiene and reconciliations, you're in bookkeeping clean up territory; if your prior-period balances are structurally wrong, you're likely looking at historical accounting clean up. Either way, the goal is the same—numbers you can trust and use.

Diagnostic & Review

  • Prior-period diagnostic to pinpoint which months or years are impacted

  • Balance sheet review to identify accounts that don't roll forward correctly

Corrections & Adjustments

  • Correction plan for accounting-level issues affecting historical financials

  • Targeted adjustments to align prior-period balances with supporting records

  • Documentation of what was changed and why (so the fix is maintainable)

Clean Output & Handoff

  • Updated financial statements for the affected period(s)

  • Clear handoff notes for ongoing bookkeeping so issues don't reappear

Ready to fix your books?

See what FlowFi can do for you

Also, if what you really need is getting fully current month-by-month, we offer catch up bookkeeping services as well.

Catch up is about bringing overdue months up to date; clean up is about fixing what’s incorrect or inconsistent often you need one or the other, and sometimes both, but we’ll help you quickly identify which applies.
