TL;DR: An industrial cleaning company in Detroit had $340K sitting in receivables over 60 days. Average days to payment was 58—nearly double their Net 30 terms. The problem wasn't bad customers. It was that nobody was systematically following up. We built an agent that monitors receivables daily, sends tiered follow-up communications, and escalates when human touch is needed. Average payment dropped to 34 days. Over-60-day receivables fell to $85K. Most customers just needed a reminder.
The Aging Report Horror
Marcus pulled the AR aging report on a Thursday afternoon. He'd been avoiding it.
$340,000 over 60 days. $180,000 over 90 days.
This wasn't a collections problem. This was a cash flow crisis hiding in plain sight.
His industrial cleaning company was doing fine by most measures. 52 employees. Contracts ranging from $2K to $50K monthly. Manufacturing plants, commercial facilities, steady work across Wayne, Oakland, and Macomb counties.
But the money wasn't coming in.
Net 30 terms. Average actual payment: 58 days. Some invoices sitting at 120 days. A few at 180.
"We're essentially financing our customers' cash flow," Marcus said. "Except we didn't agree to that."
Why Nobody Was Calling
Here's the uncomfortable truth about collections at most small businesses: nobody wants to do it.
The office manager doesn't want to be the person who nags clients. The owner is busy running operations. The bookkeeper sends invoices but considers follow-up outside their role.
So it becomes a thing that happens "when there's time." Quarterly, maybe. When cash gets tight enough that someone finally sits down with the aging report.
Marcus had tried assigning collections to his office manager. She lasted two weeks before the awkwardness overwhelmed her. "I can't call these people every day. They're our clients."
He tried doing it himself. Made a list of overdue accounts, started calling, got pulled into an emergency at one of the plants, never finished the list. The list sat on his desk until the next crisis made him look at AR again.
Nobody wanted to be the collections person. So nobody was.
The customers weren't trying to stiff them. Most of them had just... forgotten. Or deprioritized. Or the invoice was sitting in someone's inbox waiting for approval that never came.
The companies that got paid on time were the ones that asked. Professionally. Consistently. That's all it took.
The Real Cost
Let's be specific about what $340K in aging receivables actually costs.
Opportunity cost: That $340K isn't earning interest. It isn't funding growth. It isn't covering payroll without a credit line.
Borrowing cost: Marcus had a $150K line of credit he tapped regularly to cover the gap between receivables and payables. Interest: 8.5%. That's real money leaving the business because customers weren't paying on time.
Write-off risk: The longer an invoice ages, the less likely it gets paid. Industry average: 10% of invoices over 90 days eventually get written off. That's $18K of Marcus's $180K that might never arrive.
Mental overhead: The anxiety of knowing money is out there but not knowing when—or if—it's coming back.
