If your business is behind on bookkeeping, you are not alone. Many business owners fall behind because they are focused on running the business, managing cash flow, handling staffing issues, or trying to keep
operations moving during difficult periods.
At OneBooks, we specialize in catch-up bookkeeping and QuickBooks cleanup for businesses that are months — and sometimes years — behind.
Most OneBooks catch-up projects fall between $300 and $9,000, with simple engagements starting near $300 and backlogs of more than three years are quoted on request. A straightforward project involving only a few missing months may start near $300, while longer or more complicated backlogs generally cost more.
The final price depends on the number of months involved, transaction volume, the number of bank and credit-card accounts, payroll activity, missing records, and the condition of the existing QuickBooks Online file.
Backlogs of more than three years vary significantly and are quoted individually. Every client receives a fixed price before work begins. For most OneBooks catch-up and cleanup projects, 50% is due to start and the remaining 50% is due at completion.
| Backlog | Clean-Up Price Range | Estimated Timeline |
| 1–3 months | $300–$750 | Several weeks |
| 4–6 months | $750–$1,500 | Several weeks |
| 7–12 months | $1,500–$3,000 | Several weeks |
| 1-2 years | $3,000–$6,000 | 1–2 months |
| 2-3 years | $6,000–$9,000 | 2–3 months |
| More than 3 years | Request a quote | Timeline provided after review |
These ranges represent typical OneBooks engagements and are not guaranteed quotes. Transaction volume, account complexity, payroll, ecommerce integrations, missing documentation, and the condition of the existing books can affect both price and completion time. OneBooks provides a fixed quote after reviewing the project.
Major cost drivers include:
Most business owners do not intentionally neglect bookkeeping. Businesses commonly fall behind due to:
Review bank accounts, payroll systems, QuickBooks files, and financial records.
Gather statements and rebuild missing financial activity month-by-month.
Reconcile accounts, correct mappings, fix duplicate entries, and repair balance sheet issues.
Deliver Profit & Loss Statements, Balance Sheets, and CPA-ready reporting.
Maintain accurate books moving forward to avoid future backlog problems.
A business came to OneBooks more than four years behind on bookkeeping with approximately 24,000 missing transactions. The business also had unresolved sales tax filings and missing documentation. OneBooks reconstructed the books, rebuilt historical liabilities, and delivered CPA-ready financial statements that allowed the business to move forward with tax filings and payment negotiations.
