The person who prepares a bank reconciliation should be independent of anyone who handles cash, signs checks, or approves payments. That independence matters more than accounting credentials, because it is what prevents the same person from both moving money and hiding the movement. In practice, who fills the role depends on your size: a sole proprietor does it themselves, a small business assigns a bookkeeper or office manager who is walled off from payments, a mid-sized company uses a staff accountant outside the AP and AR teams, and larger organizations run it through a dedicated internal audit function.
Why Independence Is the Real Qualification
Bank reconciliation is one of the simplest fraud-prevention tools a business has. It compares your internal records against what the bank reports, and any mismatch gets investigated. That protection collapses if the person doing the comparison is the same person who moved the money. Someone who handles deposits and also reconciles can pocket cash and then adjust the books to hide it. Someone who signs checks and reconciles can write unauthorized payments and mark them as legitimate expenses.
The principle is called segregation of duties. It splits financial responsibilities across multiple people so no single employee controls every step of a transaction. For reconciliation, the preparer should be walled off from three categories of work: custody of funds, authorization of payments, and recording of day-to-day transactions. When one person handles all three plus the reconciliation, the control is gone.
Duties That Disqualify Someone From Preparing the Reconciliation
Knowing the principle is useful. Knowing which specific tasks disqualify a candidate is more useful. The person reconciling your bank account should not:
- Handle deposits or have safe access. If they can touch incoming cash, they can skim funds before deposit and then adjust the reconciliation to cover the shortage.
- Process payroll or accounts payable. Combining payment processing with reconciliation makes it easy to create fictitious vendors or ghost employees and then suppress the evidence during review.
- Initiate wire transfers or electronic payments. Someone who can move money electronically and also reconcile can authorize payments to themselves and ensure those transactions never get flagged.
- Sign checks or authorize withdrawals. An authorized signer who also reconciles can write checks to personal accounts and mark them as business expenses.
The pattern is simple. If a task lets someone move money in or out of the account, that person should not also be the one verifying the account’s accuracy.
Who Does It at Each Business Size
Who actually sits down and reconciles depends on how many people you have to work with.
Sole Proprietors and Solo Operations
In a one-person business, the owner does it. There is no way around this and no point pretending otherwise. The owner handles deposits, signs checks, and reconciles the account. That lack of separation is an inherent risk of solo businesses, but the alternative of not reconciling at all is worse. Even without segregation of duties, the process still catches bank errors, forgotten charges, and unauthorized third-party transactions.
Small Businesses With a Few Employees
Small businesses typically assign reconciliation to a bookkeeper or office manager who does not handle cash or process payments. If your bookkeeper already enters invoices and cuts checks, they are the wrong person for this task. A better setup has the bookkeeper handle day-to-day entries while the owner or a separate employee reconciles monthly. Even that minimal separation goes a long way.
Mid-Sized Companies
Mid-sized companies usually assign a staff accountant or senior accountant who sits outside the accounts payable and accounts receivable teams. The accountant has read-only access to the bank portal, downloads statements, and compares them against the general ledger. A controller or accounting manager then reviews the finished reconciliation before it gets filed.
Large and Publicly Traded Companies
Large organizations build reconciliation into formal internal audit programs. A dedicated team handles the comparison, a separate team investigates exceptions, and management reviews the results.
For public companies, this is a legal requirement rather than a preference. The Sarbanes-Oxley Act requires every issuer to maintain adequate internal controls over financial reporting and requires management to assess those controls annually. An independent auditor then reviews that assessment. Reconciliation staffing is part of that legally mandated control environment.1Office of the Law Revision Counsel. 15 US Code 7262 – Management Assessment of Internal Controls
When You Cannot Fully Separate Duties
Most small businesses cannot afford to hire enough people to fully segregate every financial function. That is normal, and it does not mean you should skip reconciliation. It means you need compensating controls, meaning extra layers of review that reduce the risk created by overlapping roles.
The most effective compensating control is direct owner review. Even if an employee prepares the reconciliation, the owner should independently log in to the bank portal with their own read-only credentials and review the statement. Look at every check that cleared, confirm the payees match your records, and verify that deposit amounts correspond to actual sales. This takes 15 to 30 minutes a month for most small businesses and catches the kinds of discrepancies that an employee with conflicting duties might suppress.
Other compensating controls include requiring dual signatures on checks above a set dollar threshold, using accounting software that logs every edit with a timestamp and username, and rotating reconciliation duties among employees periodically. None of these fully replaces proper segregation, but stacking several of them narrows the window for undetected fraud.
How Automation Affects Who You Need
Modern accounting software can automatically match bank transactions against ledger entries, flagging only the exceptions that need human attention. This shifts the reconciliation role from line-by-line comparison to exception review. Someone still has to evaluate the flagged items, approve adjustments, and sign off on the final reconciliation, and the independence requirement applies to that person just as much as it would in a manual process.
What automation changes is the skill level and time commitment required. A process that once took a trained accountant several hours can often be completed in a fraction of the time. For growing businesses, this also means you do not have to hire additional accounting staff every time transaction volume climbs, so the person you assign today can usually keep the role as you scale.
The Second Person: Reviewer
The reconciliation is not complete when the preparer signs off. A second person, ideally at a supervisory level, should review the finished document before it gets filed. The reviewer confirms that the reconciliation was actually performed rather than rubber-stamped, that adjusting entries have adequate documentation, and that outstanding items from prior months are being resolved rather than carried forward indefinitely.
If your business is too small for a formal supervisor, the owner fills this role. What matters is that a different person reviews the work than prepared it. The reviewer should have independent access to bank statements, either through their own online login or by receiving statements directly from the bank. That access prevents the preparer from altering the statement before the review. Document the review with a signature and date so the audit trail shows the control was actually exercised.
The reconciliation is a detection tool, but only if the person performing it investigates discrepancies rather than forcing the numbers to match. That is where the independence of both the preparer and the reviewer pays off. Someone with no stake in the outcome is more likely to ask uncomfortable questions about an unexplained variance, and that willingness is what turns the reconciliation from paperwork into a control.
