Quick answer: OneBooks is a Wyckoff-based bookkeeping firm serving Bergen County businesses that need QuickBooks Online cleanup. We fix unreconciled accounts, duplicate or miscoded transactions, and unreliable balance-sheet accounts. Cleanup is quoted at a fixed price after file review, typically $750 to $6,000, and every cleanup is reviewed and delivered by a Certified QuickBooks ProAdvisor.
A QuickBooks file can contain months or years of transactions and still produce unreliable financial statements. Cleanup focuses on correcting the bookkeeping already in the file so the business can move forward with reconciled, understandable records.
We investigate reconciliation differences and correct bookkeeping issues so the accounts can be brought into agreement with the underlying statements.
We identify duplicate bank-feed activity and transactions recorded to inappropriate income, expense, asset, liability or equity accounts.
We review Uncategorized Income, Uncategorized Expense and similar holding accounts and classify transactions using the available records and business information.
Old balances can result from customer payments, deposits or bank-feed transactions being recorded incorrectly. We trace the activity and correct the bookkeeping.
We review old invoices, customer payments, vendor bills, credits and payments that may be creating inaccurate receivable or payable balances.
We review bookkeeping balances against available payroll reports, sales-tax returns and payment records. For New Jersey businesses, relevant records may include New Jersey sales-tax returns and payroll filings such as NJ-927 and WR-30. OneBooks provides bookkeeping services, not tax-return preparation or legal advice.
We review loans, credit cards, clearing accounts, fixed assets, owner activity and unexplained historical balances that affect the reliability of the financial statements.
| Service | Typical situation | Primary work |
|---|---|---|
| QuickBooks Cleanup | The activity exists, but some bookkeeping is wrong. | Diagnose, correct and reconcile. |
| Catch-Up Bookkeeping | Months or years of bookkeeping were never completed. | Reconstruct missing bookkeeping. |
| Cleanup + Catch-Up | Some work is missing and some existing work is wrong. | Reconstruct and correct. |
Typical fixed-price ranges are shown below. Every engagement is quoted individually after the QuickBooks file is reviewed and the cleanup scope is defined. For the full statewide scope, see QuickBooks cleanup services in New Jersey.
