Yes, you can change your business bank account, but the process takes planning because money and payments are tied to your old account number
Switching business bank accounts is possible and happens for many reasons — a bank's fees are too high, customer service is poor, you need different features, or you found a better rate elsewhere. The main challenge is not the switch itself but the timing and notification. Your customers, vendors, and payment systems all know your current account number. If you close the old account before everything moves over, payments will bounce and you could lose money.
The process typically takes two to four weeks from start to finish, depending on how many automatic payments and deposits you have. Most banks can help you move money between accounts, but you are responsible for telling everyone who sends you money or takes money from you that your account details have changed.
Key Takeaways
- You must notify customers, vendors, and any service that automatically withdraws from your account before you close the old account.
- Automatic deposits (like customer payments or payroll) need to be updated at the source — the payer's bank or payroll system — not at your bank.
- Keep your old account open for at least two to four weeks after opening the new one to catch any payments still coming to the old number.
- Your bank can transfer existing balances between accounts, but you handle the notification work yourself.
- Some businesses use both accounts temporarily during the transition to avoid missed payments.
What you need to do before closing the old account
Start by making a list of everyone and everything connected to your current account. This includes customers who pay you by automatic transfer, vendors you pay automatically, payroll services, loan payments, tax payments, insurance payments, and any subscription services that charge your account. Go through your bank statements from the last three months — every deposit and withdrawal tells you who needs to be notified.
For each automatic payment or deposit, you have two jobs: stop it at the source and restart it at your new bank. If a customer pays you automatically, they need to update your account number in their system — your bank cannot do this for them. If you pay a vendor automatically, you need to log into that vendor's system and change your account details there. This is the step most people underestimate. A single missed notification can mean a payment bounces, a service gets cut off, or a customer's payment fails and they think you refused it.
Contact your new bank and ask whether they offer a transition service. Some banks have tools that help you notify payees, or they can provide you with a list of what needs to change. Not all banks offer this, so ask directly.
How to move money from your old account to your new one
Your new bank can transfer your existing balance to your new account. This is usually free and takes one to three business days. Call your new bank's business service line and ask them to initiate an ACH transfer (a standard electronic money movement) from your old account to the new one. You will need to provide your old account number and routing number, which you can find on a check or your old bank's website.
Some banks let you do this online through their business portal. Others require a phone call or a visit to a branch. Ask your new bank which method they use and whether there are any limits on how much you can transfer at once.
Do not close your old account when ready after the transfer. Money can still arrive at the old account for weeks after you have opened the new one, especially if some payees have not yet updated their records.
Timing: when to open the new account and when to close the old one
Open your new account first, before you notify anyone of the change. This gives you a working account number to share. Once the new account is open and you have transferred your balance, begin notifying payees and payers. Give them at least one week's notice if possible, though some may need more time depending on their internal processes.
After you have notified everyone, wait at least two weeks before closing the old account. During this time, monitor both accounts. Watch for any payments that still arrive at the old account — these tell you that someone did not update their records. If you see a payment come in, contact that payer when ready and confirm they have your new details.
Some business owners keep the old account open for a full month as a safety net. This costs a little extra in fees but prevents the stress of a missed payment. Once you are confident all payments have switched over, you can close the old account. Call your old bank and ask them to close it. They will usually ask whether you want any remaining balance transferred to your new account.
What happens to checks and payment cards tied to the old account
If you have business checks printed with your old account number, you can still use them after you switch banks — they will not bounce. However, the money will come from your old account, not your new one. This is why you need to keep the old account open during the transition. Once you are ready to close it, order new checks from your new bank with the new account number.
Business debit cards and credit cards are separate from your bank account. If your card is tied to the old account, contact your bank about whether you need a new card or whether they can reissue it linked to the new account. Some banks do this automatically; others require you to request it.
Reasons to switch and what to consider first
Common reasons to change accounts include lower fees, better customer service, online tools that work better for your business, or a move to a bank that specializes in your industry. Before you switch, compare what you will actually save. Add up all the monthly fees at your current bank and compare them to the new bank's fees. Some banks waive fees for the first few months, so check whether the lower rate is permanent.
Also consider whether your current bank offers anything you would lose — a relationship with a loan officer, a line of credit you might need, or integration with accounting software you use. Switching is worth the effort if the new bank genuinely serves your business better, but not if you are chasing a promotional rate that expires in three months.
If something goes wrong during the switch
If a payment bounces because it arrived at your closed old account, contact that payer when ready and ask them to resubmit it to your new account. Most will do this without penalty. If a vendor stops service because a payment failed, call them and explain that you switched banks and provide your new account details. Most vendors are used to this and will restart service once the payment goes through.
If you accidentally closed your old account too soon and payments are still arriving, contact your old bank. Some banks can reopen a recently closed account or redirect incoming payments to your new account. The sooner you notice, the easier it is to fix.
Frequently Asked Questions
Can I keep my old account open while using the new one?
Yes, and you should. Keep both accounts open for at least two to four weeks after switching. This catches any payments that still arrive at the old account and prevents bounced checks or failed transfers. Once you confirm all payments have moved over, you can close the old account.
Do I need to tell my accountant or bookkeeper about the switch?
Yes. If someone else manages your books or tax filings, let them know the account number is changing. They may need to update their records or reconciliation process. Give them the old and new account numbers and the date of the switch.
What if a customer's automatic payment fails because they are still using my old account number?
Contact them when ready with your new account details and ask them to resubmit the payment. Most customers will do this right away. If the payment was time-sensitive (like a loan payment), contact your lender to explain the situation — many will waive late fees if you can show you switched banks.
How long does it take to switch banks completely?
The actual account opening takes one to three days. Transferring your balance takes one to three days. Notifying everyone and waiting for all payments to switch over takes two to four weeks. Plan for the full month to be safe.
Will switching banks affect my business credit?
No. Your business credit is tied to your tax ID and payment history, not to your bank account number. Switching accounts does not change your credit score or history.
