The cost of a QuickBooks cleanup depends mainly on how many account-months need to be reconciled and how much of the evidence is missing. An account-month is one bank or card account for one month. A file with one bank account that is three months behind is a small job. A file with six accounts, two years unreconciled and no statements on hand is a reconstruction. Whatever the price, it should buy the same set of deliverables: reconciled accounts with reports, a written record of what was changed, and a list of what could not be resolved. If a quote does not name those outputs, you cannot tell what you are paying for.
This post sets out the factors that drive the price, how fixed fees and hourly billing differ, and what to ask for before you agree to either.
The factors that drive the price
These are listed roughly in order of how much they move the effort.
- Months out of reconciliation. Every account has to be reconciled month by month, oldest first, because each month's closing balance is the next month's opening balance. Twelve months behind is roughly twelve times the reconciliation work of one, and old months take longer, because nobody remembers what the transactions were.
- Number of accounts. Count bank accounts, credit cards, loan accounts, payment processors and payroll clearing accounts. Each needs its own reconciliation, so the number of accounts multiplies the months.
- Transaction volume. Two hundred bank lines a month is a different job from two thousand. High volume from card sales or online payouts usually needs clearing-account work, not just categorisation.
- State of the evidence. Statements, invoices and receipts that can be downloaded quickly make work fast. Missing statements, paper records or a previous bookkeeper who cannot be reached make it slow, and some of the time goes into chasing documents rather than accounting.
- Payroll. Payroll entries need agreeing to payroll reports and tax filings. If payroll ran outside QuickBooks and was posted as lump sums, expect extra work to break it down.
- Sales tax or VAT. If returns have been filed, the books have to support them. Differences between the books and filed returns have to be explained, not just corrected.
- Inventory, multi-currency and integrations. Each adds its own layer: stock valuation, revaluation of foreign balances, and apps such as e-commerce platforms that post their own entries, sometimes duplicating bank feed transactions.
- Balance sheet leftovers. Undeposited Funds, Opening Balance Equity, suspense accounts and impossible receivable or payable balances. These are often where the real time goes, because each one has to be traced to its cause.
- Required standard. Books that are "tax-ready" for a return preparer differ from books that must stand up to an audit or a lender's review. The second needs more documentation per adjustment.
Fixed fee or hourly
Both are legitimate, and each puts the risk in a different place.
Hourly billing puts the risk on you. If the file is worse than expected, the cost rises. It suits work whose scope genuinely cannot be seen in advance, such as a file with no statements at all. Ask for a not-to-exceed figure and a check-in point before it is reached.
A fixed fee puts the risk on the provider. It can only be offered honestly after someone has looked at the file. A fixed quote given without access to the books is a guess, and the gap usually comes back later as change requests or quietly reduced scope.
The practical middle ground is a short review of one file, followed by a fixed quote for the cleanup with a written scope. The review should establish the months, accounts, volumes and known problem balances. Those are the factors above, and they make the quote checkable.
What a fixed fee should include
A written scope should state:
- The period, with a start and an end date, and which accounts are covered.
- The standard: reconciled and categorised, or reconciled with supporting documentation for adjustments.
- What is out of scope: for example payroll tax filings, prior-year tax returns, or rebuilding inventory.
- What you must provide, and by when. Statements, access and answers to questions are usually the biggest cause of delay.
- How unresolved items are handled. Some items cannot be resolved. The scope should say they will be listed, not forced.
The deliverables to insist on
Whatever the price, these should come back with the file.
- Reconciled accounts, with the reports. A completed reconciliation for every account and every month in scope, with the reconciliation report saved or exported. "Reconciled" without reports cannot be checked.
- A trial balance before and after. The trial balance at the end of the period as it was received and as it was returned, so the effect of the cleanup can be seen account by account.
- A memo of what changed. A list of adjustments: what was wrong, what was done, and the reason. Large or judgment-based entries should each be described, not grouped into one line.
- A list of what could not be resolved. Every item left open, with the amount and what is needed to close it. A cleanup that reports nothing unresolved on a badly behind file deserves a second look.
- Balance sheet accounts explained. Undeposited Funds, Opening Balance Equity and any suspense or clearing accounts either at zero or supported by a schedule.
- The books locked. A closing date set at the end of the cleaned period, with a password, so the work is not undone by the next edit.
Warning signs in a quote
- A price given without any access to the file or any questions about it.
- A promise to finish "however far behind you are" within a fixed number of days.
- No mention of reconciliation reports, an adjustment memo or unresolved items.
- A cleanup that ends with one large journal entry to bring balances into line. That moves the problem; it does not solve it.
How to reduce your own cost
The provider's time is only part of the cost. Delays on your side add to it. Download statements for every account and month in advance. Name one person to answer questions. Answer in batches, not one email at a time. Tell the provider at the start about anything unusual: owner payments, loans between related businesses, or a period when someone else kept the books.
