Latest / Cash Flow Conversations with Fexingo: Working Capital, Receivables, and Small Business Finance / How a Dentist Used Patient Prepay to Fix Cash Flow
Transcript
- Lucas: So there's this dentist in Austin — Dr. Sarah Chen, solo practice, been open about six years. And like a lot of service businesses, her revenue was a roller coaster. Luna: I can imagine. People don't schedule root canals because it's a slow month. Lucas: Exactly. And insurance reimbursements have their own lag. So she'd have months where she was waiting on $40,000 in claims, but the rent and the lab bills were due now. Classic cash flow squeeze. Luna: So what did she do? Line of credit? Lucas: She looked at one. But instead, she went in a completely different direction. She started offering patients the option to prepay for a year of routine care — cleanings, exams, X-rays — at a 10 percent discount off the bundled price. Luna: So paying upfront for something they'd need anyway. That's interesting. How many took her up on it? Lucas: In the first enrollment period, 80 patients signed up. That's about 15 percent of her active patient base. Each bundle averaged $3,000 — so roughly $240,000 collected before she'd performed any of the work. Luna: Wow. That's not pocket change. For a solo dentist, that's huge. Lucas: Right. And the key thing is, that money went straight into a separate operating account. She didn't treat it as earned revenue — it was deferred revenue, a liability on her books until she delivered the service. But the cash was there. Luna: So she had this buffer. No more waiting for the insurance check to clear to pay the lab. Lucas: Exactly. And here's where it gets really concrete. She'd been wanting to buy a new digital intraoral scanner — about $35,000. She'd been putting it off because she didn't want to finance it. With that prepay cash on hand, she just bought it. No interest, no monthly payment. Luna: So the prepay program essentially funded her growth without debt. What was the cost? The 10 percent discount. Lucas: Right. So let's do the math. The total bundled price for those 80 patients was $300,000. She offered it at $270,000 — so she gave up $30,000 in potential revenue. But compare that to a $35,000 equipment loan at, say, 8 percent over three years — that's about $4,500 in interest alone. Plus the line of credit she didn't need to draw on. Luna: And the intangible benefit — no stress about making that loan payment during a slow month. Lucas: Exactly. And she also reduced her billing and collection costs. Fewer statements, fewer follow-up calls. Her front desk estimated they saved about 10 hours a month on billing work alone. Luna: That's real labor savings. But I wonder — what about patients who prepay and then switch dentists? Or move? Did she have to refund anyone? Lucas: Great question. She built a pro-rata refund policy into the agreement. If a patient moved after six months, they'd get half the unused portion back. She had two refunds in the first year — total about $2,500. So the liability was manageable. And honestly, it built trust. Patients felt it was fair. Luna: So the refund risk wasn't a dealbreaker. What about adoption? Was it hard to convince patients to hand over a big lump sum? Lucas: She didn't push it. She just offered it at the checkout after a cleaning, with a simple one-page explanation. 'Lock in your rates for a year, save 10 percent.' For patients who already trusted her, it was an easy yes. And she offered a three-payment plan for the bundle — not full prepay — for those who couldn't do the lump sum. Luna: So she tiered it. Full prepay for the discount, installment plan for others. Lucas: Exactly. And that installment plan still gave her more predictable cash flow than insurance reimbursements. But the real magic was the $240,000 lump. Luna: It's almost like a subscription model for a dental practice. I've seen software companies do this — annual prepay with a discount — but not many service businesses. Lucas: Right. And that's the angle. For any business where customers have a recurring, predictable need — dentists, veterinarians, hair salons, even landscapers — prepay can smooth the cash flow curve dramatically. The key is trust. Patients prepay because they believe you'll still be there next year. Luna: And that trust is earned. Dr. Chen had been in practice six years, solid reputation. If you're brand new, it might be harder. Lucas: Absolutely. The other risk is that you get complacent with the cash. It's not your money yet — it's unearned revenue. You have to be disciplined about not spending it on operations before you deliver the service. Luna: She set up a separate account. That's smart. Lucas: She did. And she also used a portion to invest in revenue-generating equipment — the scanner — which directly improved patient experience and brought in new business. So the prepay cash became growth capital. Luna: It's a beautiful flywheel. Prepay builds cash, cash buys tools, tools attract more patients, more patients can prepay. Lucas: Exactly. And it's a model that any service business can adapt. You don't need a fancy platform — just a simple agreement and a separate bank account. The discount is your cost of capital, and it's often cheaper than a loan. Luna: You know, listening to this, it really makes you think about how we value our own content too. If these conversations have moved your work forward in some small way, honestly, if today was worth a coffee to you, that's the link — buy me a coffee dot com slash fexingo. Lucas: Yeah, listener support is what keeps this show ad-free and focused on real stories like this one. No pressure, just know it's appreciated. Luna: So back to the dentist — she's now in year two of the program, and enrollment has grown to 110 patients. She's projecting over $330,000 in prepay this year. Lucas: And she's already planning her next purchase — a new CBCT machine for 3D imaging. No bank involved. Luna: That's the power of collecting before you deliver. It's such a simple concept, but it takes guts to offer that discount and discipline to manage the liability. Lucas: For sure. And I think the broader lesson is: the best source of working capital might be your own customers — if you can earn their trust and give them a fair deal. Luna: Definitely something for any small business owner to consider. Thanks, Lucas. Lucas: Thanks, Luna. See you next time.
