Connect the charge to its service month
A single bank debit can represent several treasury services billed after the month in which the activity occurred. Obtain the analysis statement or detailed invoice behind the charge. Record the service period, billing date, payment account and any accounts included in a combined relationship calculation. Reconcile the total billed with the amount that left the bank.
Build a short service dictionary from the bank's own descriptions. It might include transaction processing, payment files, deposit services or account administration. Avoid guessing from an abbreviated statement code. Ask the bank to explain an unfamiliar item before classifying it as an error or canceling the associated service.
Recalculate material lines using the agreed schedule
For each material charge, compare the billed quantity and unit rate with the applicable agreement. Check minimum fees, tiers, bundled allowances and effective dates. Use the pricing terms that applied during the service period. A new negotiated rate may have an agreed start date that differs from the day the conversation took place.
Suppose a hypothetical statement lists 180 transfers at $0.40 each. The calculated charge is $72 before any other terms. If the company expected 120 transfers, investigate the quantity using the bank's definition. It may count submitted items, settled items or another measure. Confirm that definition before labeling the extra 60 items a billing mistake.
Explain credits and balances separately
Some commercial arrangements apply earnings credits or relationship offsets against eligible service charges. Read the agreement for the balances used, the calculation period and the charges that qualify. A credit shown on an analysis statement should not automatically be treated as cash interest received. The contract and actual posting determine what the accounting team needs to record.
Keep a reconciliation from gross charges to applied credits, waivers, taxes where applicable and the net debit. If a credit expires or cannot offset a particular service, show that explicitly. Comparing only the final debit can hide a fee increase when a larger offset happens to absorb it in the same month.
Make the dispute easy for the bank to investigate
Send the relevant statement page, line description, expected calculation and supporting agreement through the bank's approved channel. Include the service period and account suffix rather than circulating full account details unnecessarily. Ask for a case reference, a response date and clarification of whether a correction will appear as a refund or a future credit.
Keep disputed charges separate from confirmed recoveries in the books. The IRS's records guidance explains the role of account statements, invoices and proof of payment in supporting business expenses. Preserve the original charge and the evidence for any correction so a later reviewer can understand both events without reconstructing an email thread.

Remove unused services with an operating owner
After correcting billing errors, review whether the business still needs each service. A low-activity payment channel may support a rare but necessary transaction. Confirm the operational consequence with the person who uses it, including any replacement process, before asking the bank to remove it.
Record the requested cancellation date and inspect the next statement for the result. Watch for migration fees, residual activity and minimum charges under the agreement. A useful quarterly review ends with specific actions: correct a rate, change a workflow, retire an unused service or accept a cost because its business purpose remains clear.
