To write a business check, fill in six fields in order using a pen with dark, permanent ink: the date, the payee’s full legal name, the numeric dollar amount, the written-out amount, an optional memo, and the signature of an authorized signer on the account. Then record the check in your register before it leaves your desk. Knowing how to write a business check well is mostly about avoiding the small openings, like blank space on the amount line or the wrong pen, that let a routine payment turn into a fraud claim.
Before You Pick Up the Pen
Confirm two things first: the recipient’s full legal name or exact business name as it appears on their bank account, and the precise dollar-and-cent amount you owe. Match the name to the invoice, not to a nickname or an abbreviation.
Use a pen with dark, permanent ink. Ballpoints work. Gel pens with pigment-based ink soak deeper into the paper and resist chemical tampering better than a standard ballpoint. Never use a pencil or a felt-tip marker, and never use erasable ink.
The Six Fields, In Order
Every business check has the same layout. Work through it top to bottom.
Date. Write the current date in the upper-right corner. Post-dating a check does not legally prevent the bank from cashing it early, so only date it for the day you actually issue it.
Pay to the Order Of. Write the recipient’s full legal or business name on this line. Start at the far-left edge of the line so no one can squeeze an extra name in front of yours. Use the name on the invoice.
Numeric amount. Enter the exact figure in the small box next to the dollar sign (sometimes called the courtesy box). Write it snugly against the dollar sign so no digit can be inserted before your number. For example: $1,250.00, not $ 1,250.00.
Written amount. Spell out the same amount in words on the long line below the payee’s name. Write cents as a fraction over 100. For $1,250.00, you would write “One thousand two hundred fifty and 00/100.” Draw a horizontal line through any remaining blank space out to the printed word “Dollars” at the end of the line. That line is your defense against someone inserting words to inflate the amount.
Memo. This field is optional but useful. Note the invoice number, account number, or a short description of what the payment covers. It helps your bookkeeper and the recipient match the check to the right transaction.
Signature. Sign on the line at the bottom right. Only someone the bank has on file as an authorized signer should sign here.
Why the Written Amount Line Wins
If the number in the box and the words on the line disagree, the bank goes with the written words. The Uniform Commercial Code states this directly: words prevail over numbers.1Cornell Law School / Legal Information Institute (LII). Uniform Commercial Code 3-114 – Contradictory Terms of Instrument That is exactly why the written-out line has to be filled in carefully and why any leftover blank space has to be closed off with a line.
Who Can Legally Sign
Only people the bank has on file as authorized signatories can sign checks on the account. Under the UCC, if someone without signing authority puts their name on a business check, that signature is treated as unauthorized and the check is not properly payable from the account.2Cornell Law School / Legal Information Institute (LII). Uniform Commercial Code 3-403 – Unauthorized Signature The bank can reject the check, and the person who signed it could face personal liability.
Many businesses require two signatures on checks above a certain dollar amount as an internal control. There is a catch worth knowing. Banks process checks through automated systems that typically do not verify the number of signatures. A dual-signature check can go through with only one signature and get paid. The UCC treats a check missing a required signature as unauthorized, which technically leaves the bank on the hook to re-credit your account. But many bank account agreements include language shifting that risk back to the customer, saying any dual-signature policy is an internal matter the bank will not monitor. Read your account agreement. The protection you think a two-signature rule gives you may not work the way you expect.
Record the Check Immediately
Every check you write should be recorded the moment you write it, either on the checkbook stub, in a paper ledger, or in your accounting software. Capture four things: the check number, the date, the payee, and the exact dollar amount. This is basic. The businesses that get in trouble are not the ones who record badly, but the ones who plan to catch up later and never do.
Those records feed your monthly bank reconciliation, where you match cleared checks against your internal register. Discrepancies during reconciliation are how you catch unauthorized transactions, duplicate payments, and processing errors. Most account agreements give you a limited window to dispute an error, so speed matters. Consistent records also give you a clean paper trail for deductible business expenses at tax time.
From the payer’s side, the money typically leaves your account within one to two business days after the recipient deposits the check. Make sure the funds are there before you hand the check over, not on the day you assume it will be deposited.
Voiding a Check You Wrote Incorrectly
If you make a mistake while writing a check, or if the payment falls through before you deliver it, void the check instead of tearing it up. Write “VOID” in large capital letters across the front in permanent ink. Make the letters large enough to cover most of the check face, but leave the account and routing numbers at the bottom legible. Do not sign a voided check.
Record the voided check in your register with the check number, the date, and a note that it was voided. That prevents confusion during reconciliation when a check number in your sequence has no matching bank transaction. Some businesses use a rubber stamp for consistency, which also helps if you void checks often for payroll or direct deposit setups.
Stopping Payment After the Check Is Gone
If a check is lost, stolen, or issued in error and has already left your possession, you can place a stop payment order with your bank. Under the UCC, any authorized signer on the account can issue a stop payment, and it takes effect as long as the bank receives it in time to act before the check clears.3Cornell Law School / Legal Information Institute (LII). Uniform Commercial Code 4-403 – Customers Right to Stop Payment; Burden of Proof of Loss
A stop payment order lasts six months. If you give the order verbally over the phone, it expires after 14 calendar days unless you follow up with written confirmation. You can renew the order for additional six-month periods as long as you do so in writing before the current one lapses.3Cornell Law School / Legal Information Institute (LII). Uniform Commercial Code 4-403 – Customers Right to Stop Payment; Burden of Proof of Loss
Expect a fee for each request. Fees at major banks typically run around $30 per order, though some institutions charge less for requests submitted online, and some premium business account packages waive the fee entirely. Call your bank before you assume the cost, especially if you need to stop multiple checks at once.
The Six-Month Expiration Is Not Automatic
A bank has no obligation to honor a check presented more than six months after its date. Certified checks are the exception and stay valid beyond that window. The rule says the bank is not required to pay a stale check, not that the bank cannot pay it. A bank that pays an old check in good faith is allowed to charge your account for it.4Cornell Law School / Legal Information Institute (LII). Uniform Commercial Code 4-404 – Bank Not Obliged to Pay Check More Than Six Months Old
That creates a practical problem. If you wrote a check eight months ago and the money is still in your account, the payee could deposit it and your bank might process it. If you know a check has been outstanding past six months, either contact the payee to reissue it or place a stop payment. Do not assume the bank will catch it.
