Bookkeeping Cleanup Cost by Months Behind
A 12 month bookkeeping backlog with 300 transactions a month is modeled at $3,769 to $6,784 when labor costs $100 an hour. This is a modeled estimate from the GlacialBooks cleanup calculator, not measured customer data.
| Months behind | Monthly transactions | Modeled hours | Modeled cost |
|---|---|---|---|
| 3 months | 100 | 9.0 to 16.2 | $900 to $1,620 |
| 3 months | 300 | 12.4 to 22.3 | $1,238 to $2,228 |
| 3 months | 600 | 17.4 to 31.4 | $1,744 to $3,139 |
| 6 months | 100 | 14.1 to 25.3 | $1,406 to $2,531 |
| 6 months | 300 | 20.8 to 37.5 | $2,081 to $3,746 |
| 6 months | 600 | 30.9 to 55.7 | $3,094 to $5,569 |
| 12 months | 100 | 24.2 to 43.5 | $2,419 to $4,354 |
| 12 months | 300 | 37.7 to 67.8 | $3,769 to $6,784 |
| 12 months | 600 | 57.9 to 104.3 | $5,794 to $10,429 |
| 18 months | 100 | 34.3 to 61.8 | $3,431 to $6,176 |
| 18 months | 300 | 54.6 to 98.2 | $5,456 to $9,821 |
| 18 months | 600 | 84.9 to 152.9 | $8,494 to $15,289 |
Methodology
Each row runs the published GlacialBooks cleanup estimator with the months and transaction volume shown. The model separates source review, monthly close reconstruction, reconciliation setup, transaction review, missing statement recovery, payroll review, and unresolved balance investigation, then applies a range around the central work estimate.
- The business has three bank or card accounts and two unresolved balances.
- All statements are available, and payroll review is excluded so the table isolates months and transaction volume.
- Labor costs $100 an hour. The estimator lets a reader replace that amount with a local or quoted rate.
- The low estimate is 75 percent of modeled central hours, and the high estimate is 135 percent.
- Complex inventory, prior tax return changes, payroll corrections, litigation, and missing source records can add work beyond this model.
Questions about the benchmark
Are these measured GlacialBooks customer costs?
No. They are modeled estimates generated from the published cleanup estimator and the assumptions on this page.
Why does transaction volume change cleanup cost?
More transactions create more classification and review work, even when the number of months and accounts stays the same.
Can missing statements or payroll increase the estimate?
Yes. The interactive estimator includes both. This table sets them to zero so months and transaction volume remain easy to compare.
