Latest / Cash Flow Conversations with Fexingo: Working Capital, Receivables, and Small Business Finance / How a Payment Calendar Helped a Plumbing Firm Avoid Collapse
Transcript
- Lucas: Today, I want to talk about a plumbing company in Phoenix that was literally weeks from shutting down — even though they had more than enough revenue coming in the door. Or at least, revenue that was supposed to come in. Luna: That's almost harder to stomach than a business that's just not selling. The money is there, it's just... stuck. Lucas: Exactly. This was a fifteen-person operation called Apex Plumbing Solutions. They'd been around for about seven years, doing residential and light commercial work. By early 2025, they were billing about three hundred thousand dollars a month, but their bank account was consistently below ten thousand dollars. Luna: So they're profitable on paper, but in practice they can't make payroll. That's a receivables crisis wearing a revenue mask. Lucas: That's exactly what it was. And the owner, a guy named Dan, came to me through a mutual contact — he was considering a merchant cash advance, which would have been an absolute disaster at their margins. So we sat down and looked at the numbers. The first thing that jumped out was the average time to payment: fifty-three days. Luna: Fifty-three days. For a service business. That's brutal. Most plumbing invoices should clear within two to three weeks. Lucas: Right. And part of the problem was that Dan had no real system for following up. He'd send an invoice by email after the job, maybe text the customer a week later if he remembered. But there was no calendar, no escalation, no way to see which accounts were drifting toward sixty or ninety days. So the first tool we built was a payment calendar. Luna: Can you describe what that actually looks like? Because 'payment calendar' sounds simple, but I'm guessing there's more to it than just writing due dates on a wall calendar. Lucas: Much more. We created a spreadsheet — color-coded by customer, not by invoice. Each row is a customer, each column is a week. The cell is green if they're current, yellow if they're between due date and thirty days overdue, orange at thirty to sixty, red at sixty plus. Dan updates it every Monday morning. It takes ten minutes. Luna: So instead of chasing individual invoices, he's managing customer relationships. That's smart — because the root cause of late payment is often the customer's own cash flow or their payment habits. Lucas: Exactly. And once Dan had that map, patterns jumped out. He noticed that about forty percent of his overdue dollars came from just eight customers, and those customers all shared one thing: they were always invoiced on the same day — the day the job finished — and they always paid between the twenty-fifth and the thirty-first of the month. Luna: So the issue wasn't that they couldn't pay. It was that their internal payment runs happened at month-end, and Dan's invoices often arrived after that window closed. Lucas: Bingo. So we didn't change the payment terms. We just changed when he sent the invoice. For those eight customers, he started invoicing on the twenty-second of the month, even if the job wasn't finished until the thirtieth. He'd send a preliminary invoice with a note: 'Work completed, final amount will be confirmed, but please schedule for this month's payment run.' Luna: And that worked? Lucas: Within two months, those eight customers went from averaging fifty-one days to pay to eleven days. Dan's overall average collection time dropped from fifty-three to thirty-two days. His cash balance went from under ten thousand to over sixty thousand in three months. Luna: That's a huge swing. And it didn't require any discounting, any factoring, any loans. Just a calendar and a bit of customer psychology. Lucas: Right. And that's the thing — most cash flow crises are actually receivables crises in disguise. The revenue is real, the customers are good, but the timing is broken. A payment calendar fixes the timing. It's the single highest-leverage tool for a small business that's profitable but cash-poor. Luna: I want to push back a little, though. Not every small business owner is a spreadsheet person. Dan clearly was willing to do the ten-minute update, but some folks I've worked with freeze up when you hand them a color-coded grid. Lucas: Totally fair. And for those owners, there are simpler versions. You can do it with sticky notes on a wall — green, yellow, orange, red. Move the note when payment arrives. Or you can use a CRM that has a receivables dashboard. The tool doesn't matter. What matters is the weekly ritual of looking at your receivables by customer, not by invoice. Luna: And I'd add that the ritual forces you to have the conversation. Because the hardest part is picking up the phone. I've seen owners who would rather take out a high-interest loan than call a customer and say 'Your payment is late.' Lucas: Right. And the payment calendar makes that call less awkward, because you're calling based on a system, not on a whim. You can say 'My system shows your invoice is in the orange zone, and I want to make sure we're on the same page.' That's very different from 'Uh, hey, you owe me money.' Luna: Yeah. It depersonalizes the ask, which helps both sides. And it also helps you prioritize — you're not calling every late customer, you're calling the ones who matter most. Lucas: Exactly. In Dan's case, we identified that his top five overdue customers represented fifty-seven percent of his total receivables. Those were the only people he called in the first week. And three of them paid within forty-eight hours of that call. Luna: Because they just needed a nudge. And the nudge came at the right time, with the right context. Lucas: Precisely. And that's the beauty of the payment calendar — it turns an abstract problem into a visible, actionable one. You stop feeling like your business is out of control and start seeing exactly where the leverage points are. Luna: Speaking of leverage, I want to ask about the longer term. Dan fixed the immediate crisis, but what happens when he grows? Does the calendar scale? Lucas: It scales if you build in automation. Once Dan had about forty regular customers, the manual calendar became a bit unwieldy. So we migrated him to a simple online tool — basically a Kanban board for receivables. Same logic, but it auto-sends reminders and flags accounts that cross thresholds. He still does a weekly review, but the system handles the daily follow-up. Luna: So the weekly review becomes a strategic check rather than a data entry chore. That's where you want to be. Lucas: Exactly. And that's what I'd recommend for any business that's doing over, say, a hundred thousand a month in revenue. Start manual, build the habit, then graduate to a tool that keeps the habit alive. Luna: Dan's story is really encouraging. It's rare to see such a clear turnaround with such simple tools. I hope more owners hear it and realize they don't need a bank loan or a factoring agreement — they just need a calendar and a bit of discipline. Lucas: Yeah, and honestly, if this episode helped you think about your own receivables in a new way, that's exactly why we do this show. We try to keep Cash Flow Conversations ad-free and focused on practical stories like Dan's. So if today's conversation was worth a coffee to you, you know where to find us — buy me a coffee dot com slash fexingo. It's a small gesture that keeps the show independent and free for everyone. Luna: And it genuinely helps. We don't have a big production budget — it's just the two of us and a lot of research. So every bit of listener support makes a difference. Lucas: Alright, back to the plumbing business. So after Dan stabilized his cash flow, he had a new problem — he started getting asked to do larger commercial jobs that required longer payment terms, sometimes net sixty. Luna: That's the classic growth trap. Your cash flow is finally healthy, and then a bigger opportunity comes along that requires you to stretch again. Lucas: Right. So we used the same calendar logic to set up a pre-qualification process. Before Dan would quote a net-sixty job, he'd ask the customer for their typical payment cycle and then map it onto his calendar. If the customer's payment run fell after the thirtieth day, he'd build in a small discount for payment within fifteen days. He didn't offer it to everyone — just the ones where the calendar showed a potential gap. Luna: So he used the calendar prospectively, not just reactively. That's a great next step — turning a diagnostic tool into a planning tool. Lucas: Exactly. By the end of 2025, Dan's average collection time was down to twenty-two days, and he had a cash reserve of about four months of operating expenses. The same business that was weeks from closing twelve months earlier. Luna: And he never took that merchant cash advance. Lucas: No, he didn't. And he's now a vocal advocate against them. He tells other owners: 'Before you borrow, look at your receivables. The money is probably already there — you just have to time it.' Luna: That's a good note to end on. Thanks, Lucas. Lucas: Thanks, Luna. See you next time.
