Checks seem a pretty mundane bit of banking, but when they say “Do not convert to ACH,” that means the payer doesn’t want the funds transferred electronically. Rather, they are requesting manual processing.
Here, learn more about the implications of these five little words on a check.
ACH System 101
First, understand what ACH is. It stands for Automated Clearing House, which is an electronic system that transfers funds throughout the United States. This network allows individuals and businesses to move money from one financial institution to another, quickly and securely.
Every time you set up automatic bill pay or receive your paycheck by direct deposit or write an eCheck, that’s ACH at work. Apps such as PayPal and Venmo also use the ACH network to send and receive money.

How Does ACH Work?
ACH transfers are initiated by either making a withdrawal or deposit into an account. You can send money to another account on a one-time basis — such as through an ACH debit to a utilities company or transferring money to a friend for your share of a restaurant meal — or opt into recurring payments. For example, some companies allow you to make automatic payments, such as for subscription services. In either case, you give permission for the receiver to initiate a withdrawal from your account.
You can also get money via an ACH credit. This happens when people receive a direct deposit of their paycheck or Social Security.
Once you or someone else initiates a transfer, the request will be processed first by your financial institution, usually by the next business day. You may be able to expedite the request, as well as schedule a transfer for a future date.
Typically, ACH transfers are faster than other types of transactions, though a potential downside is that it’s only available for transfers within the U.S. (That’s one of the distinctions between an ACH vs. wire transfer, incidentally; the latter has global reach.)
What Is Check Conversion?
Check conversion refers to the process of transforming a check payment into an electronic payment. This usually happens at one of these three points:
• Point of Purchase (POP), meaning when a purchase is made, say, at a store
• Accounts Receivable Conversion (ARC), when a business receives a check by mail and then processes it electronically
• Back Office Conversion (BOC), or when a check is processed electronically after acceptance at, say, the office of a retail location
What Does Conversion to ACH Mean?
ACH conversion describes the fact that a paper check will be converted to a payment that’s processed through the ACH network. In other words, even though a paper check was written and used as payment, it will become an electronic ACH transfer.

Why Might a Check Be Converted to ACH?
The main reason why a check may be converted is to save time and money when processing payments. Plus, converting a check payment to ACH could be more efficient, as it can help financial institutions detect potential bank fraud earlier, make fewer mistakes, and even result in fewer returned payments. The service of ACH transfers is typically free to consumers.

Can a Check Be Converted to ACH?
A check can be converted to ACH in many cases (unless it says “do not convert to ACH”) to help it move swiftly and securely; there’s no check to get lost or be forged, for instance.
How the conversion usually happens: When the check gets deposited in a checking account, the payment details are captured from the check. Then, the check itself will be stored securely by the financial institution — unless you have the physical check and are making a mobile deposit. If the check is converted in person, then the original check will be voided and given back to the payer.
If the check was converted for ACH, it will typically appear on a bank statement as a direct payment (or withdrawal) in the same section as ATM withdrawals or other forms of electronic payments. It could also appear as a check payment — some banks include a scanned image of the check or include the payment details.

What Does It Mean When a Check Says ‘Do Not Convert to ACH’?
When a check says “do not convert to ACH,” it means that the payer does not want to make a payment electronically. Instead, the payment needs to be processed manually from one financial institution to another through the check collection system.
More specifically, it means the financial institution will contact the other financial institution to request the funds, which are then delivered through a local clearinghouse exchange or other form organization like the Federal Reserve Bank.
It’s rare to receive a check that says this on it, but if you do, there’s not much to be done to alter the payer’s request.
What Is the Benefit to the Drawee if a Check Says ‘Do Not Convert to ACH’?
Checks that say “Do not convert to ACH” may sometimes be printed when a payer is issuing multiple checks; for example, if a class action suit is being paid out. In this case, perhaps the check issuer does not want the much faster electronic processing of their checks. Perhaps it suits them to have a slower payment process.
What Is the Difference Between ACH and a Check?
The difference between ACH and check payments is the network by which they’re processed. ACH payments are processed electronically through the ACH network, whereas non-converted paper checks are processed manually. In many cases, ACH transfers are processed faster than paper checks, since you may have to wait for a check to clear.
The Takeaway
When it comes to getting paid, converting a check to ACH is most likely the fastest, safest way. Unfortunately, there’s not much you can do if the check you receive says “Do not convert to ACH,” however rare they may be. You’ll probably need to deposit it and allow the extra time required for it to become available cash.

FAQ
Can an ACH payment be declined?
Yes, an ACH payment may be declined or rejected for a few reasons, the most common one being that the payer doesn’t have enough funds in their account for the transfer. Other reasons include the account was closed by the time the transfer took place, the funds have been frozen, or the payer has stopped the payment request.
What does “ineligible for conversion” mean on a check?
If a check says “ineligible for conversion,” it means the check can’t be converted to an ACH payment. This may be due to the paper the check was printed on. The payee needs to either cash or deposit the actual check at a local branch.
Why would a bank reject a check?
There are several reasons a bank would reject a check, including:
• You don’t have an account at the bank where you want to cash the check
• You don’t have proper identification to show to the bank
• The amount may be too large for the financial institution to process
• The check is void (for example, the check is old and the payment is no longer valid)
• The signature on the check doesn’t match what the bank has on file

SoFi members with Eligible Direct Deposit activity can earn 3.80% annual percentage yield (APY) on savings balances (including Vaults) and 0.50% APY on checking balances. Eligible Direct Deposit means a recurring deposit of regular income to an account holder’s SoFi Checking or Savings account, including payroll, pension, or government benefit payments (e.g., Social Security), made by the account holder’s employer, payroll or benefits provider or government agency (“Eligible Direct Deposit”) via the Automated Clearing House (“ACH”) Network during a 30-day Evaluation Period (as defined below).
Although we do our best to recognize all Eligible Direct Deposits, a small number of employers, payroll providers, benefits providers, or government agencies do not designate payments as direct deposit. To ensure you're earning 3.80% APY, we encourage you to check your APY Details page the day after your Eligible Direct Deposit arrives. If your APY is not showing as 3.80%, contact us at 855-456-7634 with the details of your Eligible Direct Deposit. As long as SoFi Bank can validate those details, you will start earning 3.80% APY from the date you contact SoFi for the rest of the current 30-day Evaluation Period. You will also be eligible for 3.80% APY on future Eligible Direct Deposits, as long as SoFi Bank can validate them.
Deposits that are not from an employer, payroll, or benefits provider or government agency, including but not limited to check deposits, peer-to-peer transfers (e.g., transfers from PayPal, Venmo, etc.), merchant transactions (e.g., transactions from PayPal, Stripe, Square, etc.), and bank ACH funds transfers and wire transfers from external accounts, or are non-recurring in nature (e.g., IRS tax refunds), do not constitute Eligible Direct Deposit activity. There is no minimum Eligible Direct Deposit amount required to qualify for the stated interest rate. SoFi members with Eligible Direct Deposit are eligible for other SoFi Plus benefits.
As an alternative to Direct Deposit, SoFi members with Qualifying Deposits can earn 3.80% APY on savings balances (including Vaults) and 0.50% APY on checking balances. Qualifying Deposits means one or more deposits that, in the aggregate, are equal to or greater than $5,000 to an account holder’s SoFi Checking and Savings account (“Qualifying Deposits”) during a 30-day Evaluation Period (as defined below). Qualifying Deposits only include those deposits from the following eligible sources: (i) ACH transfers, (ii) inbound wire transfers, (iii) peer-to-peer transfers (i.e., external transfers from PayPal, Venmo, etc. and internal peer-to-peer transfers from a SoFi account belonging to another account holder), (iv) check deposits, (v) instant funding to your SoFi Bank Debit Card, (vi) push payments to your SoFi Bank Debit Card, and (vii) cash deposits. Qualifying Deposits do not include: (i) transfers between an account holder’s Checking account, Savings account, and/or Vaults; (ii) interest payments; (iii) bonuses issued by SoFi Bank or its affiliates; or (iv) credits, reversals, and refunds from SoFi Bank, N.A. (“SoFi Bank”) or from a merchant. SoFi members with Qualifying Deposits are not eligible for other SoFi Plus benefits.
SoFi Bank shall, in its sole discretion, assess each account holder’s Eligible Direct Deposit activity and Qualifying Deposits throughout each 30-Day Evaluation Period to determine the applicability of rates and may request additional documentation for verification of eligibility. The 30-Day Evaluation Period refers to the “Start Date” and “End Date” set forth on the APY Details page of your account, which comprises a period of 30 calendar days (the “30-Day Evaluation Period”). You can access the APY Details page at any time by logging into your SoFi account on the SoFi mobile app or SoFi website and selecting either (i) Banking > Savings > Current APY or (ii) Banking > Checking > Current APY. Upon receiving an Eligible Direct Deposit or receipt of $5,000 in Qualifying Deposits to your account, you will begin earning 3.80% APY on savings balances (including Vaults) and 0.50% on checking balances on or before the following calendar day. You will continue to earn these APYs for (i) the remainder of the current 30-Day Evaluation Period and through the end of the subsequent 30-Day Evaluation Period and (ii) any following 30-day Evaluation Periods during which SoFi Bank determines you to have Eligible Direct Deposit activity or $5,000 in Qualifying Deposits without interruption.
SoFi Bank reserves the right to grant a grace period to account holders following a change in Eligible Direct Deposit activity or Qualifying Deposits activity before adjusting rates. If SoFi Bank grants you a grace period, the dates for such grace period will be reflected on the APY Details page of your account. If SoFi Bank determines that you did not have Eligible Direct Deposit activity or $5,000 in Qualifying Deposits during the current 30-day Evaluation Period and, if applicable, the grace period, then you will begin earning the rates earned by account holders without either Eligible Direct Deposit or Qualifying Deposits until SoFi Bank recognizes Eligible Direct Deposit activity or receives $5,000 in Qualifying Deposits in a subsequent 30-Day Evaluation Period. For the avoidance of doubt, an account holder with both Eligible Direct Deposit activity and Qualifying Deposits will earn the rates earned by account holders with Eligible Direct Deposit.
Separately, SoFi members who enroll in SoFi Plus by paying the SoFi Plus Subscription Fee every 30 days can also earn 3.80% APY on savings balances (including Vaults) and 0.50% APY on checking balances. For additional details, see the SoFi Plus Terms and Conditions at https://www.sofi.com/terms-of-use/#plus.
Members without either Eligible Direct Deposit activity or Qualifying Deposits, as determined by SoFi Bank, during a 30-Day Evaluation Period and, if applicable, the grace period, or who do not enroll in SoFi Plus by paying the SoFi Plus Subscription Fee every 30 days, will earn 1.00% APY on savings balances (including Vaults) and 0.50% APY on checking balances.
Interest rates are variable and subject to change at any time. These rates are current as of 1/24/25. There is no minimum balance requirement. Additional information can be found at http://www.sofi.com/legal/banking-rate-sheet.
