Latest / Cash Flow Conversations with Fexingo: Working Capital, Receivables, and Small Business Finance / How a 24-Hour Follow-Up Rule Fixed a Contractor's Cash Flow
Transcript
- Lucas: Maria Torres runs an electrical contracting business in Phoenix. Fifteen employees, mostly residential service calls and small commercial build-outs. Solid margins, reliable crews — but she told me she was constantly borrowing against her home equity line just to make payroll. Luna: That's brutal. Especially if the work itself is profitable. Where was the cash getting stuck? Lucas: Receivables. Her average invoice was paid in 67 days. Her contracts said net-30. So the gap wasn't a mystery — it was a process problem. And the fix turned out to be surprisingly low-tech. Luna: Our conversations have helped a lot of business owners spot these sorts of gaps. And if these episodes have helped you tighten up your own operation, a couple of dollars a month is genuinely what keeps them ad-free — buy me a coffee dot com slash fexingo. It makes a real difference. Lucas: And we mean that. Okay — so Maria's fix. What she did was implement a strict 24-hour follow-up rule. The day after she sent an invoice, someone from her office called the customer's accounts payable department. Not to nag — just to confirm receipt and ask if they had any questions. Luna: That's it? A confirmation call? Lucas: That's it. But she did it consistently. Every invoice, every time. And the results were dramatic. Within four months, her average receivables dropped from 67 days to 34 days. Luna: So cutting the time in half just by picking up the phone. What's the psychology there? Lucas: A lot of it is just payment prioritization. Accounts payable departments get flooded with invoices. The ones that get paid first are the ones that are top of mind. A quick call moves your invoice from the bottom of the stack to the middle — or the top. Luna: But doesn't that annoy the AP folks? Getting called the day after you send something? Lucas: Maria's script was careful. No pressure, no 'when are you going to pay?' It was: 'Hi, we sent invoice number 402 yesterday. Just want to make sure you received it and everything looks correct. No errors? Great. Do you have any questions about the scope of work?' That's it. Polite, helpful, under 60 seconds. Luna: And it works because most invoices do have errors — wrong PO number, missing line item, tax rate mismatch. Catching that early prevents a 30-day delay turning into a 60-day delay. Lucas: Exactly. Maria told me that before the 24-hour rule, she'd find out about a mismatch three weeks later when the customer finally called. Then she'd have to reissue the invoice, and the clock started over. The call catches those issues immediately. Luna: So the 24-hour window isn't just about being persistent — it's about being proactive. What about scalability? This works for a 15-person contractor, but does it work for a business with 500 invoices a month? Lucas: That's the fair question. At some volume, you can't make 500 personal calls every day. But the principle still applies. You automate the first touch — an email confirmation with a read receipt, maybe a text message. The key is that the first follow-up happens within 24 to 48 hours, not two weeks. Luna: So it's about speed of first contact, not necessarily the medium. I've seen studies that show the probability of collecting an invoice drops by about 50 percent after 30 days. Every day earlier you engage, the better. Lucas: Right. And Maria's case proves it. She didn't change her terms, she didn't offer discounts, she didn't threaten late fees. She just changed the timing of her follow-up. That's a working capital gain that cost her zero dollars. Luna: Zero dollars, but it does cost time. Did she have to hire someone to make those calls? Lucas: She didn't. She trained her office manager to do it as part of the daily routine. It takes about 20 minutes a day for her volume — maybe 30 invoices a week. The office manager spreads the calls across the morning. Maria says it's the highest roi 20 minutes in the business. Luna: I want to push on one thing. What about customers who explicitly say 'don't call, just email'? Some large companies have policies against phone follow-ups. Lucas: Great point. Maria's approach is to ask during the call if they prefer email. Some customers say, 'Please don't call, just send a reminder.' And she respects that. But even then, the email goes out the next day, not two weeks later. The principle is the same: act fast, follow the customer's preference, but act. Luna: So the tool is flexible. The rule is the cadence. I think a lot of small business owners hear 'improve your receivables' and immediately think about factoring or invoice financing — which costs money. This is a reminder that the cheapest fix is often operational. Lucas: Maria would agree. She told me the first month of the 24-hour rule felt awkward. Her office manager was nervous about bothering people. But after three months, the cash flow was so much smoother that she couldn't imagine going back. She's actually stopped using her home equity line entirely. Luna: That's the real win. Not just a metric improvement — a structural change in how the business finances itself. What about the downside? Any customers who got annoyed and took their business elsewhere? Lucas: She lost exactly one customer in the first year. A property management company that said they preferred to deal with vendors who 'didn't bug them.' Maria's take was that if a single polite confirmation call is enough to lose a client, that client was probably going to be a problem down the line anyway. Luna: That's a fair filter. And it aligns with something we've talked about before — that the customers who pay on time are often the ones who appreciate clear communication. The ones who don't want you to follow up are often the ones who are going to pay late anyway. Lucas: Exactly. Now, I want to zoom out for a second. This 24-hour rule is a specific tactic, but the broader lesson is about what I'd call 'receivables discipline.' Most small businesses treat invoicing as a one-and-done event. You send the invoice, you wait. But it should be a process with multiple stages. Luna: Define those stages. Lucas: Stage one: delivery and confirmation — that's the 24-hour call. Stage two: the gentle reminder at day seven if no payment. Stage three: the escalation at day 15 — maybe a more formal email or a call to a supervisor. Stage four: the final notice at day 30, with a clear consequence. Maria now has that whole sequence mapped out. She used to just send the invoice and wait until day 45 to panic. Luna: So the 24-hour rule is really the catalyst for building a whole receivables system. It forces you to engage early, which makes the later stages feel less confrontational because you've already built a relationship with the AP person. Lucas: That's the insight. The call at day one is friendly. It's not a collection call — it's a service call. 'Just making sure everything's okay.' By the time you have to have a harder conversation at day 15 or day 30, you're not a stranger. You're the person who was helpful from the start. Luna: I want to bring in a data point. I read a study from the Institute of Credit Management that said the average small business in the US spends about 15 hours a week on collections activities. Maria's 20 minutes a day is about 1.7 hours a week. That's a huge efficiency gain. Lucas: Because she's front-loading the work. Most small businesses spend those 15 hours doing reactive collection calls — chasing invoices that are already 45 days overdue. Maria's approach prevents most of those late payments from ever happening, so she doesn't need the heavy collection effort later. Luna: Preventive medicine versus emergency room. So for a business owner listening right now who's thinking 'I should try this,' what's the first step? Lucas: Pick one customer — preferably a repeat customer with a regular invoice volume. Implement the 24-hour rule just for that customer. See what happens. Maria actually started with her top five customers and expanded from there. The proof is in the data, and within a month you'll see if the average payment time shifts. Luna: And if it works for that one customer, you have a case study to show your team. 'See, this is why we're making these calls.' That's a lot easier than mandating a new policy from the top. Lucas: Exactly. And one more thing — Maria also found that her customers appreciated it. Several of them told her, 'Nobody has ever called to check if our invoice was correct. That's really professional.' She turned a collection activity into a relationship-building moment. Luna: That's a great note to end on. The thing that fixes your cash flow also makes you look more competent to your customers. That's a rare win-win. Lucas: Absolutely.
