Positive pay is a bank service in which a business sends the bank a list of the checks it has issued, and the bank pays only checks that match the list. Mismatches are flagged for you to approve or reject. It is worth asking about if you write many or large checks, or have been a fraud target.
This guide explains how positive pay works, what you send the bank, which businesses tend to use it and what to ask before you sign up. Availability, features and fees differ from bank to bank, so your bank is the place to confirm the details.
How does positive pay work?
The idea is simple. You know exactly which checks you wrote, for how much and to whom. The bank only knows what shows up for payment. Positive pay lets the bank compare those two lists before it releases your money.
- You write or print your checks as usual and record each one: number, date, amount and, in some systems, the payee.
- You send the bank that list, called an issue file, by uploading a file or typing the checks into the bank's online portal.
- When a check is presented for payment at a branch or through the clearing system, the bank compares it with your list.
- If it matches, the bank pays it.
- If it does not match, or is not on the list at all, the bank flags it as an exception and tells you.
- You review the exception, usually through online banking, and tell the bank to pay or return it before the bank's deadline.
A mismatch can mean fraud, such as a counterfeit check with your account number or a changed amount. It can also mean an honest mistake, like a check you forgot to add to the list. Positive pay catches both, and you decide what to do.
What are the types of positive pay?
| Type | What gets compared | Who does the matching |
|---|---|---|
| Positive pay | Check number and amount against your issue file | The bank, with exceptions sent to you |
| Payee positive pay | Check number, amount and payee name | The bank, with exceptions sent to you |
| Reverse positive pay | A list of checks the bank received, against your own records | You, by reviewing the bank's daily list |
| ACH positive pay or debit block | Electronic debits against approved sources | The bank, with your approval list |
Not every bank offers every version. Payee positive pay is the stronger one against altered checks, since changing the payee name on a stolen check is a common trick. Reverse positive pay needs more daily effort from you but needs no issue file.
Who offers positive pay?
Many banks offer positive pay on business checking accounts, usually as part of their online business banking or treasury tools. Some smaller banks and credit unions offer a lighter version or none at all. It is generally a business product, so a personal checking account is unlikely to have it.
Fees vary. Some banks charge a monthly fee, some a per-item fee, and some include it with certain account packages. Ask for the pricing in writing, along with any setup or minimum requirements.
What do you need to send the bank?
- The check number of every check you issue.
- The amount, to the cent.
- The issue date.
- The payee name, if you use payee positive pay.
- Voided checks, so the bank knows not to pay them.
Timing matters. You usually have to send the list before the checks are likely to be deposited, often the same day you issue them. Late or missing entries cause exceptions, which means extra work and sometimes a rejected legitimate check.
What happens at an exception?
You get an alert by email, text or the banking portal, along with the check image. You compare it with the invoice or your register, then choose pay or return. The bank sets a decision window, often a few hours or the next morning, and many banks have a default for what happens if you do not respond, either pay or return.
Ask your bank what the default is and who in your business receives alerts. If the person who gets the alerts is away, an unanswered exception can cause a valid check to bounce or a bad one to be paid.
When is positive pay worth asking about?
- You issue a large number of checks each month.
- You write checks for large amounts, such as rent, tuition or supplier payments.
- Your business or a similar one has already been hit by a counterfeit, altered or stolen check.
- Blank check stock is handled by several people or stored in more than one place.
- A lender, insurer or investor expects strong payment controls.
It may be unnecessary for a very small business that writes a handful of checks a month, keeps blank stock locked up and reconciles weekly. In that case free controls, described in check fraud prevention for small business, may be enough. It is still a sensible question to put to your banker.
What does positive pay not cover?
Positive pay protects against checks that do not match your records. It does not help if a fraudster tricks you into writing a real check to the wrong person, for example by pretending to be a vendor with new bank details. That kind of scam needs a human control, such as calling the vendor on a known number. See how to avoid check printing scams.
How do you prepare to use positive pay?
Good records make positive pay easy. Keep a register that lists every check number you issue with its date, amount and payee, and update it the day you print or write each check. If you also number checks in order, a gap in the sequence is easy to spot and explain.
Decide who sends the list and who answers alerts, and name a backup for both. Then run a small test with your bank for a week or two before relying on it, so you learn how exceptions look and how fast you need to respond.
What questions should you ask your bank?
- Do you offer positive pay or payee positive pay for my account type?
- What does it cost, including setup and per-item charges?
- How do I send the issue file, and what formats work?
- What is the daily cutoff for sending the list and for answering exceptions?
- What happens if I do not respond: pay or return?
- Can more than one person receive alerts?
- Do you offer protection for electronic debits as well?

Next steps
Start by counting how many checks you write each month and how much blank stock sits in your office. Then call your bank, use the question list above, and compare the fee with the risk you are covering. Keep a reliable record either way, as described in how to keep a digital record of printed checks.
