It is not catching up on data entry. The sequence is oldest period first: establish verified opening balances, reconcile every account month by month, resolve the balance sheet, then close each period so the corrections stop moving.
People picture cleanup as a large amount of categorizing. Some of it is. But the categorizing is the easy part, and doing it first is how cleanups go wrong.
Here is the actual sequence.
1. Establish where the last good ground is
Before touching anything, find the most recent period that was genuinely reconciled and closed — every account matched to its statement, no forced entries.
That date is the foundation. Everything after it gets rebuilt. Everything before it is left alone unless there is specific evidence of a problem, because reopening closed periods without reason creates more work than it solves.
Sometimes the answer is "never." That is a different and larger job, and it is better to know at the start.
2. Fix the structure before the transactions
If the chart of accounts is wrong, categorizing two years of transactions into it produces two years of well-organized nonsense.
So the structure gets repaired first: accounts that duplicate each other merged, missing accounts created, the cost-of-goods-sold versus operating-expenses split corrected. Then the transactions have somewhere sensible to go.
This is also where the opening balance gets verified. If Opening Balance Equity is carrying an unexplained figure, that is a setup error, and every period since inherits it.
3. Work forward, oldest first
This is the part people find counterintuitive. Why not start with the most recent month, which matters most?
Because each period's closing balance is the next period's opening balance. Reconcile March before January and you are reconciling against an opening figure you have not verified. When January turns out to contain an error, March has to be redone.
Oldest first means each period closes on ground that has already been established. It feels slower and it is dramatically faster.
4. Separate what should never have been mixed
Usually the largest single chunk of the work: personal spending on business cards, owner draws recorded as expenses, another entity's costs paid from this one's account.
Each of these is a judgment call requiring someone who was there. This is why cleanups involve questions — a good cleanup generates a list of "what was this?" items rather than guessing, and the client answering them quickly is the single biggest factor in how long the job takes.
5. Reconcile, properly
Every account, every period, matched to the actual statement. No plug entries. Where a difference cannot be resolved, it gets documented as an open item rather than buried.
That last part matters. A cleanup that ends with three unexplained differences, clearly documented, is more useful than one that ends with a suspiciously clean set of books and a $4,100 adjusting entry nobody can account for.
6. Produce corrected statements and hand over
Restated financials for each closed period, a summary of what changed and why, and a list of anything still open. If prior returns were filed from the old figures, that summary is what your CPA needs to decide whether anything requires amending — their call, not ours.
What determines the size
Not the number of months, which is what everyone assumes. Four things, roughly in order of impact:
- Whether anything was ever reconciled. Books that were reconciled but not categorized are far quicker than the reverse.
- Commingling. Every mixed transaction is a decision, and decisions do not scale.
- Number of accounts and entities. Multi-entity work multiplies rather than adds, because intercompany transactions have to agree on both sides.
- Record availability. Missing statements mean reconstruction from whatever exists.
That is why we look before quoting, and why the quote is a fixed price rather than an hourly estimate. Cleanup starts at $1,000, with the most complex multi-year and multi-entity work quoted individually — because the jobs at either end are genuinely different. The pricing page sets out the three tiers, and the review itself carries no obligation.
Why opening balances come first
Everything downstream rests on them. If the starting cash, receivables, payables, loans and equity are wrong, every month reconciled afterwards reconciles to a wrong base and the file remains unreliable no matter how much work goes into it.
Establishing them means agreeing cash to a statement, loans to lender balances, and equity to the last filed return. Where a prior return exists, it is usually the most reliable anchor available.
What gets found along the way
Duplicated transactions from feed re-imports. Payroll liabilities that never cleared because payments were coded to expense. Personal spending recorded as business expense. Deposits recorded net of fees. Sales tax collected and sitting in revenue.
Each is ordinary and each changes the numbers materially. A cleanup is as much investigation as data entry, which is why it is priced differently from ongoing bookkeeping.
Where it stops
A cleanup produces reconciled books and a defensible balance sheet. It does not amend prior returns, and it does not take tax positions — those are your CPA’s, informed by what the cleanup found.
Where corrected numbers change a filed year materially, that becomes a conversation with the CPA about whether an amendment is warranted. It is a separate decision with its own considerations.
Closing behind it
The last step is locking each cleaned period so corrections stop moving. Without that, a later entry silently changes a month someone already signed off, and the cleanup starts undoing itself.
Common questions
- What does a bookkeeping cleanup involve?
- Establishing verified opening balances, reconciling each account month by month from the oldest period forward, resolving balance sheet errors, then closing each period.
- Why does it run oldest first?
- Because each period’s closing balances are the next period’s opening. Correcting a later period first means redoing it when an earlier fix lands.
- How long does a cleanup take?
- It depends on the number of periods and how available the evidence is. Recent years move quickly; older ones are slowed by missing statements.
- Is cleanup the same as catch-up?
- Catch-up is recording work never done. Cleanup is correcting work done wrong. Most engagements are some of both.
- What do I need to provide?
- Bank and credit statements for every month, loan statements, payroll reports and any filed returns. Those anchor the reconciliation.
