Identify the purpose before choosing an expense account
A withdrawal moves money out of the bank, but it does not establish what the business bought. Ask who received the cash, why it was withdrawn and what happened next. The money may replenish a float, fund an approved purchase, remain in a safe or represent an owner transaction. Each route needs its own accounting treatment.
IRS Publication 583 advises retaining evidence for cash business payments and making a contemporaneous explanation when a receipt cannot be obtained. Keep that evidence linked to the withdrawal and the later payment. A bank or ATM receipt establishes the withdrawal; it does not identify the goods or services eventually purchased.

Track custody until the cash is spent or returned
Record the amount, date, bank account, recipient and authorized purpose. Obtain acknowledgment when cash is handed to another person. If the money enters a petty cash or till fund, connect it to that fund's count and ledger. If an employee holds it temporarily, track the amount as an advance or other appropriate balance under the accountant's policy. Separate any bank withdrawal fee from the cash physically received so the custodian is accountable for the correct amount.
Require unused cash to be returned through the agreed process and document the amount. A purchase receipt smaller than the withdrawal leaves a balance to explain. Do not assume the difference is a fee or incidental expense without evidence.
For a hypothetical $600 withdrawal used for a $425 documented purchase, the remaining $175 must still be accounted for. It might be returned, held for another approved purpose or remain unresolved. The bank debit alone cannot support posting the entire $600 as the purchase expense.
Substantiate the underlying payment
Collect the supplier receipt or invoice, business purpose and proof that the cash was paid. Identify the payee and date clearly. Where the receipt lacks detail, obtain appropriate supporting information promptly. Follow the company's review process for missing evidence and ask the accountant about tax substantiation where relevant.
Separate purchases from owner withdrawals, employee reimbursements and loans. A descriptive memo should state the actual event. Avoid using miscellaneous expense as a holding place that later readers will mistake for a confirmed business cost.
Check whether the purchase is already recorded through accounts payable or an expense claim. If so, apply the cash payment to the existing record rather than creating another expense from the bank withdrawal. Retain the relationship between the withdrawal, cash custodian and final payment.
Review open cash advances at the close
List withdrawals that have not been fully supported, spent or returned. Include the remaining amount, person responsible and next follow-up date. Request a physical count where cash is still held. An old advance should not disappear from review because the original bank transaction has been reconciled.
Have an authorized reviewer assess unresolved balances and the appropriate next action. Apply employment, legal and accounting requirements before making deductions or reclassifying amounts owed by a person. The bookkeeping record should support the decision rather than substitute for the required approval.
For recurring withdrawals, consider whether a controlled payment method or a formal cash fund would make records clearer. Base that decision on the actual operating need. Continue to preserve the existing cash trail until all outstanding withdrawals have a supported destination and the corresponding ledger balances reconcile.
