Counterfeit or Altered Business Checks

Counterfeit or Altered Business Checks

Check fraud continues to evolve, but businesses that combine good internal controls with daily account monitoring can significantly reduce their risk.

September 01, 2026

Paper checks remain an important payment method for many businesses, but they also continue to be a favorite target for criminals.

Today’s fraudsters don’t rely on obvious forgeries. With access to stolen account information, high-quality printers, and digital editing tools, counterfeit and altered checks can closely resemble legitimate business payments.

The good news is that check fraud is often preventable.

The businesses that experience the fewest losses aren’t necessarily those with the most sophisticated technology. They’re the ones with strong internal procedures, employees who recognize warning signs, and business owners who regularly monitor their accounts.

Key Highlights

  • Check fraud continues to evolve alongside new technology.

  • Criminals often target businesses with weak payment controls.

  • Daily account monitoring can help detect fraud before losses grow.

  • Layering technology with sound internal procedures provides the strongest protection.

  • Your Business Banker can help identify fraud prevention tools that fit your business.

How Check Fraud Happens

Most counterfeit or altered check fraud begins long before a fraudulent check is presented for payment.

Criminals first obtain legitimate account information. That may happen through stolen mail, compromised mailboxes, data breaches, phishing scams, or even checks that were improperly discarded.

Once they have account and routing numbers, they may create counterfeit checks or alter legitimate ones by changing the payee or dollar amount.

Because today’s counterfeit checks often look authentic, businesses can’t rely on appearance alone to detect fraud.

Warning Signs You Shouldn’t Ignore

Fraud is often discovered because something simply doesn’t look right.

Pay close attention if you notice:

  • Missing checks or unexpected gaps in check numbers.

  • Checks clearing for unfamiliar vendors.

  • Payments that don’t match your records.

  • Unusual dollar amounts or payment activity.

  • Employees or vendors reporting checks that never arrived.

No single warning sign confirms fraud, but unusual activity should always be investigated promptly.

Strengthen Your Internal Controls

One of the most effective ways to reduce fraud is by making it more difficult for criminals to succeed.

Simple practices can make a significant difference, including:

  • Store blank checks in a secure location.

  • Limit who can issue or approve payments.

  • Separate payment preparation from payment approval whenever possible.

  • Reconcile bank accounts promptly.

  • Shred outdated financial documents instead of discarding them.

  • Consider electronic payments for recurring vendors when appropriate.

Fraud often succeeds when multiple small weaknesses exist. Strengthening each step in the payment process helps close those gaps.

Make Account Monitoring Part of Your Routine

One of the simplest fraud prevention habits is also one of the most effective.

Review your business accounts every business day.

The sooner suspicious activity is identified, the more options you may have to limit financial losses and work with your bank to respond.

Many businesses also benefit from account alerts that notify designated employees of large transactions or unusual activity.

Routine monitoring often detects problems before they become much larger ones.

Use the Fraud Prevention Tools Available to You

Technology has become one of the strongest defenses against check fraud.

Services such as Positive Pay compare checks presented for payment against the checks your business has actually issued. If something doesn’t match, the item can be flagged for review before payment is processed.

Depending on your payment volume, additional treasury management services and fraud prevention tools may also help strengthen your overall security.

The right solution depends on the size of your business, the number of checks you issue, and how your payment process is managed.

How First Bank of Berne Helps

Protecting your business from fraud involves more than responding after something goes wrong.

Our Business Bankers work with customers to review payment processes, discuss fraud prevention strategies, and recommend treasury management services that fit the way each business operates. Whether it’s implementing Positive Pay, improving payment controls, or evaluating account monitoring tools, we help businesses build practical safeguards that reduce risk without disrupting day-to-day operations.

Fraud continues to evolve, and your fraud prevention strategy should evolve with it.

Closing Perspective

Criminals continue to find new ways to target businesses, but the fundamentals of fraud prevention remain remarkably consistent.

Strong internal controls, informed employees, routine account monitoring, and the right banking tools work together to create multiple layers of protection.

No business can eliminate fraud risk entirely. But businesses that stay alert, review their payment processes regularly, and work closely with trusted financial partners are often in a much stronger position to detect suspicious activity early and minimize potential losses.

A few minutes spent reviewing your payment procedures today could help prevent a much larger problem tomorrow.
