Messy books rarely get fixed by "catching up on data entry." They get fixed by working in the right order, so each step builds on the last. This is the sequence we use on cleanup engagements at Lemoti.
Step 1: Lock down the accounts
- List every bank account, credit card, loan, and payment processor the business uses.
- Confirm every one of them is connected to your accounting file with live bank feeds.
- Close accounts that are no longer used — and mark them clearly in the chart of accounts.
Step 2: Reconcile before you categorize
Most owners start by re-coding transactions. Start with reconciliations instead — they tell you whether the data is even complete.
- Reconcile each bank and credit card account month by month, oldest first.
- Chase down missing months of statements now, not later.
- Flag unreconciled differences — duplicates, missing transactions, or manual entries that never cleared.
Step 3: Fix the coding
- Sort transactions by payee and re-code in bulk — one vendor at a time is far faster than one transaction at a time.
- Empty the "Uncategorized Expense" and "Ask My Accountant" accounts. Every dollar needs a real home.
- Separate owner draws and personal spending from business expenses. This is the most common (and most expensive) error we find.
Step 4: Clean the balance sheet
The P&L gets the attention, but the balance sheet is where old problems hide.
- Match loan balances to lender statements and split payments between principal and interest.
- Review accounts receivable and payable for stale items that were paid long ago or will never be collected.
- Verify opening balances — a wrong opening balance quietly corrupts every report after it.
- Reconcile payroll liabilities to your payroll provider's reports.
Step 5: Rebuild the structure
- Trim the chart of accounts to what you actually use — 40 useful accounts beat 200 confusing ones.
- Set a monthly close routine so the mess doesn't come back (see our Monthly Close Checklist).
How long does this take? A typical 6–12 month cleanup takes us two to four weeks. The books come back tax-ready, lender-ready, and — most importantly — trustworthy.
