What to do when your business checking account has a problem

Most business checking account problems fall into a few categories: unauthorized transactions, missing deposits, frozen accounts, overdraft disputes, or errors on your statement. The speed of resolution depends on what went wrong and which bank you use, but you can move faster by reporting the issue to the right department immediately and providing documentation the first time you contact them.

Your bank has legal timelines for investigating certain problems—typically 10 business days for initial review and 45 calendar days for a full investigation on unauthorized transactions. However, many banks resolve routine issues in 2 to 5 business days if you report them correctly and have the supporting documents ready.

Key Takeaways

  • Report the problem to your bank's fraud or disputes department within 60 days of discovering it; waiting longer can forfeit your right to a refund.
  • Gather your statement, transaction records, and any communications with the other party before you call, so you do not have to call back.
  • Ask the bank representative for a case or reference number, the name of the investigator assigned, and the expected resolution date in writing.
  • If your account is frozen, ask whether it is a hold for investigation, a compliance freeze, or a security measure—the reason determines how long it lasts.
  • If the bank denies your dispute after investigation, you can escalate to your state banking regulator or the Consumer Financial Protection Bureau.

Unauthorized transactions and fraud claims

Call your bank's fraud department as soon as you notice a transaction you did not authorize. Do not wait for the statement to arrive. Most banks have a 24-hour fraud line separate from customer service; the number is usually on the back of your debit card or in your online banking portal under "Security" or "Report Fraud."

When you call, have your account number, the transaction date, the amount, and the merchant name ready. Tell the representative you want to dispute the charge as unauthorized. The bank will typically place a temporary credit in your account within one to three business days while they investigate, though this is not may provide—some banks investigate first and credit later.

The bank will contact the merchant's bank to request a chargeback. If the merchant's bank agrees the charge was unauthorized, you get the money back permanently. If they dispute the chargeback, the investigation can take up to 45 days. During this time, keep all documentation: emails, receipts, statements, and a written summary of what happened and when you reported it.

Missing or delayed deposits

If a deposit you made does not appear in your account within the expected timeframe, first check whether you deposited it correctly. Mobile deposits sometimes fail silently if the image is blurry, the check is damaged, or the amount does not match what you wrote. Log into your mobile banking app and look for a "pending" or "processing" status on the deposit.

If the deposit shows as processed but the money is not in your account, contact your bank's customer service line with the deposit date, amount, and method (mobile, ATM, or teller). Ask them to trace the deposit. This usually takes 2 to 5 business days. If the deposit came from another bank, the sending bank may also need to investigate on their end.

If a customer's check or wire transfer to your business is missing, ask the sender to verify they sent it to the correct account number and routing number. Many delays happen because the account number was transposed by one digit. Once you confirm the details are correct, your bank can file a trace request with the sending bank, which typically takes 5 to 10 business days.

Frozen or locked accounts

A frozen account means you cannot withdraw money or make transfers, though deposits may still post. Banks freeze accounts for three main reasons: fraud investigation, compliance review, or a security hold. The reason matters because it determines how long the freeze lasts and what you need to do to lift it.

Call your bank immediately and ask which type of freeze is in place. If it is a fraud investigation, the freeze typically lasts 10 to 45 days while the bank reviews transactions. If it is a compliance freeze, the bank is reviewing your account for suspicious activity patterns—these can last longer and may require you to provide documentation of your business, the source of large deposits, or the purpose of frequent transfers. A security hold is usually the shortest; it may lift within 24 hours once you verify your identity.

Ask the bank what documents they need to lift the freeze faster. For a business account, this might include your business license, articles of incorporation, recent bank statements, or tax returns. Providing these documents can reduce the freeze period from weeks to days. Get the name of the compliance officer handling your account and ask for a written timeline.

Overdraft disputes and NSF fees

If your account went negative and you were charged an overdraft or non-sufficient funds (NSF) fee, you can dispute it if the fee was applied in error or if you believe the bank's sequencing of transactions was unfair. Banks process transactions in different orders—some clear largest-to-smallest, others clear in the order received—and this can affect which transactions trigger an overdraft.

Request a detailed transaction log from the bank showing the exact order in which transactions posted on the day you went negative. Compare this to the order they were initiated. If the bank reordered transactions in a way that created an overdraft when one would not have occurred otherwise, you have grounds to dispute the fee.

Call the bank and ask to speak with a supervisor in the disputes department. Explain the sequencing issue and provide your transaction log. Many banks will reverse one overdraft fee per year as a courtesy, especially if you have been a customer for a while. If they refuse, you can escalate the complaint to your state banking regulator.

Statement errors and duplicate charges

Review your business checking statement line by line each month. If you see a duplicate charge, a charge from an unfamiliar merchant, or an amount that does not match your receipt, report it within 60 days of the statement date. After 60 days, the bank is not required to investigate.

Gather your receipt or invoice for the transaction in question. Call the bank's disputes department and provide the transaction date, amount, merchant name, and a brief explanation of why it is wrong. If it is a duplicate, explain when the correct charge posted and when the duplicate appeared. If the amount is wrong, provide your receipt showing the correct amount.

The bank will typically credit your account temporarily while they investigate. They will contact the merchant to request documentation of the transaction. If the merchant cannot prove the charge was legitimate, the credit becomes permanent. If the merchant provides proof, the bank will debit your account again and notify you of the outcome.

Escalating a dispute after the bank says no

If your bank investigates and denies your dispute, you have the right to escalate. Ask the bank for a written explanation of their decision, including the evidence they reviewed and why they concluded the charge was valid. This document is important for your next step.

File a complaint with your state banking regulator. Each state has a banking commissioner or department of financial regulation. You can find the correct office by searching "[your state] banking regulator" or by visiting the Conference of State Bank Supervisors website. Include the bank's written decision, your documentation, and a clear explanation of why you disagree.

You can also file a complaint with the Consumer Financial Protection Bureau (CFPB) at consumerfinance.gov. The CFPB forwards complaints to the bank and tracks patterns of complaints. While they cannot force the bank to refund you, a complaint on record can pressure the bank to reconsider, and it creates a public record if other customers have had similar issues with that bank.

Preventing future account problems

Set up account alerts through your bank's online portal. Most banks allow you to receive notifications when your balance drops below a certain amount, when a large transaction posts, or when a transfer is initiated. These alerts can help you catch fraud or errors within hours instead of days.

Reconcile your business checking account monthly against your bank statement. This means comparing every deposit and withdrawal in your records to the statement. Many accounting software programs do this automatically, but you should review the results. Catching errors early makes them easier to resolve.

Keep receipts and invoices for at least one year, organized by date. If you need to dispute a charge, you will have proof of what you paid for and when. For wire transfers and ACH payments, save confirmation emails or screenshots showing the amount, recipient, and date sent.

Frequently Asked Questions

How long does a bank have to investigate a disputed transaction?

The bank must complete an initial review within 10 business days and a full investigation within 45 calendar days. They must notify you of the outcome in writing. Some banks resolve disputes faster, but 45 days is the legal maximum.

Can I get my money back while the bank investigates?

For unauthorized transactions, many banks place a temporary credit in your account within one to three business days. For other disputes, it depends on the bank's policy. Ask the representative whether a provisional credit is available while they investigate.

What if the bank freezes my account and I need to pay employees or vendors?

Contact the bank immediately and explain the business impact. Ask whether they can lift the freeze on deposits or allow transfers up to a certain amount while the investigation continues. Some banks will grant limited access if you can demonstrate the funds are needed for payroll or critical expenses.

Do I lose my right to dispute if I wait too long?

Yes. You must report unauthorized transactions within 60 days of the statement date. After 60 days, the bank is not required to investigate. For other errors, the timeline varies by bank and transaction type, but reporting within 30 days is safest.

What should I do if my bank refuses to reverse a fee I think is wrong?

Ask for the decision in writing and the name of the supervisor who made it. Then file a complaint with your state banking regulator or the Consumer Financial Protection Bureau. Include the bank's written decision and your documentation of why you believe the fee was incorrect.
