Credit risk usually focuses on the financial health of a customer before a sale is made. We analyze credit reports, check references, and set limits. One of the most significant exposure points happens after the credit decision is made, right at the moment of delivery. For many distributors and manufacturers, the final exchange of goods for payment relies on a physical handoff. A driver drops off product and picks up a paper check. This looks like a secure transaction. The goods are delivered, and payment is in hand.

That piece of paper is not immediate funds. It creates a temporal gap, a blind spot that can last anywhere from two to four days. During this window, the customer has the product, but the supplier has not yet confirmed the validity of the payment. This delay is where fraud thrives.

The Disconnect Between Delivery and Deposit

When a driver accepts a check, they can't verify funds. The check travels in the truck cab, returns to the warehouse, and sits overnight if the clerk has left. Then it takes 2-3 days to clear.

Day 1: Driver delivers product, picks up check. Warehouse clerk already left.

Day 2: Check deposited.

Day 3-4: Check clears or bounces.

By the time the bank flags an NSF or closed account, the customer has had your inventory for 48-72 hours. If the check bounces, the product is gone and the "customer" has disappeared.

You possess a promise of payment that can't be verified for days. The customer possesses your inventory immediately.

Why The Gap Exists

To close this window, we have to understand why it remains open despite advancements in digital banking. The failure is a combination of legacy habits and process silos.

The Logistics-Finance Silo

Drivers operate in a physical world of routes, traffic, and loading docks. Finance teams operate in a digital world of ledgers and bank portals. The physical check is the only bridge between these two worlds, and it is a slow one. Drivers are not equipped with point-of-sale verification tools, so they cannot validate a check upon receipt. They accept it based on trust. The validation process is deferred until the check physically reaches a finance professional, which creates the time lag.

The "Friday Afternoon" Effect

Office hours vs. delivery hours creates a critical operational flaw. Warehouses and delivery fleets often operate 24/7 or late into the evening. Administrative offices typically close at 5:00 PM. If a check arrives at the branch at 5:30 PM, it sits in a safe or a desk drawer until the next morning. If this happens on a Friday, that check sits until Monday. The float extends to four or five days, giving a fraudster ample time to disappear.

ERPs Assume "Good Faith"

Most ERP systems record the payment as soon as the check is logged or applied. The customer's balance may technically show as "paid" or "pending," releasing up credit availability for new orders. The system assumes the check is good until proven bad. This default stance of trust allows repeat fraud, where a bad actor might place a second order quickly before the first check bounces.

Intentional Fraud vs. Cash Flow Gaps

There is a distinction between a customer who is simply poor at cash management and a bad actor.

  • Cash Flow Gaps: A legitimate business might write a check hoping sales from the delivered product will cover it by the time it clears. This is risky, but the intent is to pay.
  • Intentional Fraud: A bad actor opens a business, orders high-value, easily liquidated stock (like tires, electronics, or copper), pays with a check from a closed account, and vanishes.

The 72-hour blind spot serves both, but the latter is unrecoverable.

How Monrovia Nursery Eliminated the Check Window

For nearly a century, Monrovia Nursery Company built its success on craftsmanship, sustainability, and customer relationships. As their business accelerated and operations expanded, their traditional method of handling payments began to show its limitations. The process of receiving mailed checks and manually matching invoices was slowing the pace of business. While it was the industry standard, Monrovia recognized the need for change. They faced a dilemma: How could they modernize payment processing without compromising their exceptional customer service?

By implementing a digital payment portal that accepts credit cards and ACH, Monrovia eliminated the check fraud window entirely. Customers could make payments through verified digital methods, giving Monrovia confirmed funds before product left the nursery. The results were dramatic. Payments were collected 4x as fast, with a payment portal adoption rate exceeding 90%. According to Frank Van Straalan, CFO at Monrovia: "We collect money faster. Compared to last year, we are $10 million ahead, which is substantial in our business."

Processing disputes, which once took weeks or even several months, can now be completed in a single day. The shift from paper checks to digital payments not only eliminated fraud risk but accelerated their entire order-to-cash cycle.

Closing the Verification Gap

Eliminating this risk requires moving verification closer to the point of exchange. We cannot rely solely on the speed of the banking system. We must change the workflow of payment acceptance.

The "Good Funds" Policy

For new accounts or customers with a history of late payments, a "Good Funds" policy is essential. This means payment must be verified before product is released. This can be achieved through:

  • ACH/Wire transfers: Confirmed prior to the truck leaving the dock.
  • Certified Funds: Requiring cashier's checks for the first 90 days.
  • Credit Card Holds: Pre-authorizing the amount before delivery.

Digital Capture at Delivery

Modernize the driver's role without turning them into accountants. Instead of accepting a physical paper check to be transported back to the office, drivers can be equipped with mobile capture tools.

  • Mobile Deposit: The driver captures the check image at the delivery site.
  • Instant Verification: The system reads the MICR line (routing and account number) and pings a database to verify if the account exists and has a positive status.
  • Electronic Conversion: The check is converted to an ACH transaction immediately, cutting days off the clearing time.

Risk-Based Payment Terms

Not all customers should have the privilege of paying by physical check upon delivery. Segment your customer base:

  • Low Risk: Long-term partners with established credit. Checks accepted.
  • Medium Risk: New accounts (under 6 months). Digital payments only.
  • High Risk: Past NSF history or irregular ordering patterns. Cash in Advance (CIA) or verified wire only.

The "Chain of Custody" Audit

If you must accept physical checks, map the timeline of that check from the customer's hand to your bank account.

  • Who touches it?
  • Where does it sit overnight?
  • How many hours pass between receipt and deposit?

If the answer is more than 24 hours, the process is broken. Implement remote deposit capture (RDC) scanners at every branch or warehouse location so checks do not need to be physically mailed or couriered to a central finance office.

Strategic Impact of Modernizing Payments

Fixing the check acceptance workflow impacts the broader financial health of the organization.

Revenue Protection

When fraud occurs involving physical goods, you lose twice: you lose the cost of the goods sold (COGS) and the potential revenue. For low-margin distributors, making up for a single fraudulent order of $10,000 might require $100,000 in new sales. Closing the blind spot protects net income directly.

Safety and Liability

Asking drivers to carry checks (or worse, cash) creates a safety risk. It makes delivery vehicles targets. Moving payments to digital channels improves driver safety and reduces liability.

Operational Efficiency

Chasing a bounced check is expensive. It involves bank fees for the returned item, AR staff time to contact the customer, reversing the payment in the ERP, restricting the account, and potential legal fees or collections agency costs. Preventing the bad check at the source removes this entire workload from the credit department.

Conclusion: A Playbook for Safer Deliveries

The reliance on physical checks in B2B transactions is declining, but it hasn't disappeared. As long as drivers are accepting paper payments, the risk of the 72-hour blind spot remains. Credit managers must treat the logistics of payment as seriously as the credit application itself.

Actionable Takeaways:

  • Audit your gap: Measure the average time between a driver accepting a check and the bank receiving the deposit. If it exceeds 24 hours, investigate the delay.
  • Empower the warehouse: If drivers return after admin staff leaves, provide the warehouse manager with a remote deposit scanner or a secure drop safe that is cleared early the next morning.
  • Shift to digital: Actively campaign to move "check on delivery" customers to ACH or credit card portals. Offer small incentives if necessary to reduce the risk of paper.
  • Verify early: For new customers, do not release goods based on a check handoff. Require cleared funds before the truck is loaded.
