Latest / Solopreneur Sessions with Fexingo: One-Person Businesses, Freelancing, and Independent Work / How a Solopreneur Built a Business on One Recurring Invoice
Transcript
- Lucas: So there's this freelance designer I've been following for about a year — let's call her Maya. She started out doing logo projects, website mockups, the usual one-off stuff. Fifteen different clients a month, each paying somewhere between five hundred and two thousand dollars. She was busy all the time and barely clearing sixty thousand dollars a year. Luna: That sounds like the classic freelance treadmill. Lots of work, not much money. Lucas: Exactly. And then about eighteen months ago, she made a change that I think is worth unpacking. She dropped all but one client and replaced those fifteen invoices with a single monthly retainer. One invoice, one client, one hundred and twenty thousand dollars a year. Luna: Wait — one client? That sounds terrifying. What if that client leaves? Lucas: That's the obvious risk, and we'll get to it. But the math is interesting. Before, she had maybe a 70 percent utilization rate — the rest was admin, proposals, chasing payments. After, she had basically 100 percent billable time because the retainer covered a fixed set of deliverables each month. No scoping new projects, no negotiating rates, no overdue invoices. Luna: So how did she convince one client to pay that much? A hundred and twenty thousand dollars is a big commitment for a single freelancer. Lucas: She didn't sell them hours. She sold them access to her design system. She had built a library of reusable components — templates, color palettes, font pairings, icon sets — and the retainer gave the client unlimited use of that system plus two monthly design sprints. It was basically a productized service. The client got consistency and speed, and she got predictable revenue. Luna: So she shifted from selling time to selling outcomes. That's the playbook a lot of productized service businesses use. Lucas: Right. And the interesting thing is, she didn't need fancy tools. She used a simple Notion page to share the design system and set up a Stripe subscription for the monthly payment. The whole infrastructure cost maybe twenty dollars a month. Luna: But let's go back to the single-client risk. If that one client decides to pivot, or gets acquired, or just wants to take design in-house, she's back to zero overnight. Lucas: That's real. And Maya actually thought about that. Her solution was to have what she calls a 'two-retainer ceiling' — she'd never take a third retainer, but she'd always keep two. She started with one, but after six months she added a second client at a smaller retainer, about forty thousand a year. So now she's at a hundred and sixty thousand total, with the second client as a buffer. Luna: So the one-invoice model evolved into a two-invoice model. That's more diversified, but still pretty concentrated. Lucas: Which is exactly the trade-off. The solopreneur's real asset here isn't the client — it's the design system. That's what she owns. If one client leaves, she can take that system to another company. The retainer is just the delivery mechanism. Luna: That's a key distinction. The product isn't the client relationship, it's the intellectual property. I've seen a lot of freelancers confuse the two. Lucas: Yeah. And Maya built in something else that I think is smart — a 90-day exit clause. Either side can cancel with 90 days notice. That gives her time to find a replacement client, and it gives the client time to transition. It keeps the relationship from feeling like a trap. Luna: So she's not locked in, and neither are they. That probably makes the retainer feel safer for both sides. Lucas: Exactly. And I think that's the real lesson here. The one-invoice model isn't about being lazy or avoiding sales. It's about designing a business where your energy goes into the work, not into the process of getting work. Luna: Okay, but I want to push back a little. For every Maya, there are probably ten freelancers who tried the retainer model and failed because they didn't have a productized offering. They just tried to sell monthly blocks of time — which is basically a subscription to their availability. Lucas: That's a great point. A retainer for hours is just a different way to bill time. It doesn't change the economics. The shift only works if you're selling something that scales — like a design system, a content library, a monthly analytics report that gets easier to produce each time. Luna: So the productized service has to have a component that gets cheaper or faster to deliver over time. Otherwise you're just pre-selling hours at a discount. Lucas: Right. And that's where I think a lot of people get it wrong. They offer a retainer at a lower hourly rate than their project rate, and then they end up working more hours for less money. Maya's retainer was actually priced higher per hour than her project rate — because she was selling access, not time. Luna: That's counterintuitive. Most people think retainers mean a discount. Lucas: Most people think wrong. If you're giving up the flexibility to take other projects, you should be compensated for that. Maya's retainer worked out to about two hundred and fifty dollars an hour for the actual time she spent. Her project rate was a hundred and fifty. Luna: So she basically got a raise by simplifying her business. That's a powerful story. Lucas: It is. And I think it points to a broader principle for solopreneurs. The goal shouldn't be to get more clients. The goal should be to build a system that delivers enough value to a small number of clients that they're happy to pay a premium for predictability. Luna: And that system — the design system, the Notion template, the recurring deliverable — that's the real business. The client is just the customer. Lucas: Exactly. And I think that's a mindset shift that a lot of freelancers never make. They stay in the project model because it feels safer to have many clients. But the data shows that the most profitable solopreneurs often have the fewest clients. Luna: Do you have any numbers on that? I'd love to see the data. Lucas: There's a survey from Indie Hackers a couple years back that looked at solo founders making over a hundred thousand dollars a year. About 40 percent of them had three or fewer clients. And the ones with a single client had the highest profit margins — because their overhead was basically zero. Luna: That's fascinating. But it also means those businesses are fragile. One bad quarter and they're done. Lucas: True. But fragility isn't the same as risk. A business with one client and a six-month runway is actually less fragile than a business with ten clients and a two-week runway. You have to look at the whole picture. Luna: That's a fair point. And Maya's exit clause gives her a three-month buffer. Plus she has the second retainer now. So she's built in some redundancy. Lucas: Right. And she's also got a waiting list of companies that want access to her design system. She just doesn't take them on because she wants to keep her workload manageable. That's a good position to be in. Luna: So for someone listening who wants to try this — what's the first step? They're currently doing project work and they want to move to a retainer model. Lucas: First, they need to identify what they can productize. It's not just about packaging hours. It's about finding a repeatable outcome they can deliver efficiently. For a writer, that might be a monthly content audit and strategy document. For a social media manager, it might be a weekly set of ten posts with analytics. Luna: So the deliverable has to be something that gets faster with repetition. The first month might take twenty hours, but by month six it's down to ten. Lucas: Exactly. And then they need to price it not based on hours, but on the value to the client. If that content audit saves the client two thousand dollars in ad spend, you can charge five hundred dollars for it. The hours don't matter. Luna: That's easier said than done. A lot of freelancers struggle with value-based pricing because they don't know what their work is actually worth to the client. Lucas: That's why Maya started with one client she already had a good relationship with. She didn't pitch a cold prospect on a retainer. She went to her best client and said, 'I want to give you more consistent support, and I want to build a system that makes your life easier. Here's what it would look like.' Luna: So she started with a warm lead. That makes sense. And the client already knew her quality, so they were more willing to take a chance on a new model. Lucas: Exactly. And she offered a three-month trial at a slightly lower rate to prove the model. After three months, the client saw the consistency and speed, and they agreed to the full price. Luna: I like that. A trial period reduces the risk for both sides. If it doesn't work, they go back to project work. Lucas: And that's the beauty of the solopreneur model. You can experiment. You can try a retainer for three months and if it's not working, you pivot. The overhead is so low that you can afford to be wrong. Luna: That's a good note to end on. Experiment, iterate, and don't be afraid to simplify. Lucas: If these conversations have moved your work forward in some small way, a handful of listeners chip in monthly through buy me a coffee dot com slash fexingo, and that's literally what funds making this many of these. It keeps the show ad-free and lets us dig into stories like Maya's without worrying about sponsors. Luna: Yeah, and it's a small group that makes it possible. We're grateful for every person who does that. Lucas: So back to Maya — she's now at eighteen months with her first retainer client and twelve with the second. She's thinking about adding a third, but she's hesitant because she doesn't want to hire. And that's the real constraint for solopreneurs: how much can you scale without adding headcount? Luna: That's the million-dollar question. And I think the answer is: you scale by building better systems, not by adding more clients. Lucas: Exactly. Maya's design system is her leverage. Every time she adds a new component to the library, she makes future work faster. Eventually, she could license that system to multiple clients without doing much additional work. That's the dream. Luna: So the one-invoice model might just be a stepping stone to a product business. First you productize your service, then you productize your product. Lucas: That's a great way to put it. And I think that's the trajectory for a lot of successful solopreneurs. They start with project work, move to retainers, and then eventually create a digital product that generates revenue while they sleep. Luna: Maya's not there yet, but she's on the path. And the retainer gives her the stability to work on that product without worrying about where next month's rent is coming from. Lucas: Exactly. So if you're a freelancer feeling the burnout of constant client churn, maybe consider: what if you only had one invoice? What would that business look like? Luna: That's a good question to leave listeners with. Thanks, Lucas. Lucas: Thanks, Luna. See you next time.
