The temptation is always there You're running something that works. Clients are happy. Money's coming in. Then someone asks if you do X, or you spot a gap in the market, or you think "well, we could easily offer Y as well." I've watched this happen dozens of times. The logic seems sound. You've got the team, the trust, the infrastructure. Why not stretch into the adjacent space? The answer is usually: because you'll break something. What I've actually seen happen I worked with a service business in London last year. They offered project management consulting. Good at it. Profitable. Then they started offering training programmes "to help clients do it themselves." The thinking was sound on paper. But within six months, the training was cannibalising the consulting revenue. More importantly, it split their attention. The founder was designing curricula instead of landing £30,000 contracts. The team was confused about which work mattered more. Both offerings suffered. They eventually killed the training division. Took them three months to recover the momentum they'd lost. I see this pattern everywhere. People building their own thing add a new service because they can, not because they should. The difference matters. The real questions to ask Before you extend what you offer, you need to know three things clearly. First: will this cannibalise your existing revenue or just add on top? Be honest here. If a client can buy the new service instead of your core offering, you've got a problem. If they'd buy it alongside, that's different. The difference between "this brings in new money" and "this redistributes money I'm already getting" is everything. Second: does this require a different type of person or skill? If your core service relies on deep expertise in one area and this new thing requires something completely different, you're now running two businesses. You'll either hire two teams or you'll have one stretched team doing neither thing well. I've seen people lose their best people because they got bored doing diluted work. Third: who actually wants this? Not "who would find it useful if they knew about it," but who's already asking for it. Demand that's sitting in your inbox is different from demand you're manufacturing. One requires you to sell it. One's already there. Pay attention to that gap. The cost of distraction is real Here's something nobody talks about: extending your service offering costs focus. Not just money. Not just time. Focus. You've got maybe three things you're genuinely brilliant at. Everything else is competent at best. When you add a fourth, something from that original three gets worse. It has to. There's only so much attention and energy in a day. I've seen people running their own thing add services and watch their core offering slide from "best in class" to "good enough." That's when clients start looking elsewhere. You don't notice it immediately. It's slow. But it happens. There's also the operational stuff. New service means new pricing, new contracts, new delivery process, new risks. It means training someone or doing it yourself. It means new marketing copy, new case studies, potentially new tools. If you're already stretched, this is the moment you break. When extension actually makes sense It's not never. I'm not saying never expand. I'm saying expand when it's strategic, not when it's convenient. Extension makes sense when: your existing clients are actively asking for it and you have capacity to deliver it without compromising what made them hire you in the first place. When the new service requires the exact same expertise, just applied differently. When demand is genuinely there, not imagined. I've seen people do this well. They offer service A, clients consistently ask for service B, it uses the same skills, they hire one person specifically for it, and suddenly they've got two revenue streams from one core competency. That works. Because they didn't dilute anything. They compounded it. The other scenario that works: you've genuinely outgrown your original service and you're looking for something that scales differently. But that's restructuring, not extension. That's different. What to do this week If you're sitting on a decision about extending what you offer, do three things before you commit to anything. First, spend 20 minutes writing down every enquiry you've had in the past six months that you turned down because it wasn't your core service. Look for patterns. Are the same types of requests coming in repeatedly? Or is it just noise? If it's pattern, you might have something. If it's noise, you probably don't. Second, ask three of your best current clients directly: "If we offered X, would you buy it from us?" Not "would you find it useful." Would they actually buy it. Write down their exact words. Not what you think they meant. What they said. Third, if you're seriously considering this, use a Decision Matrix to score it properly. I use this with people at ALIRA all the time. Map it against your capacity, your expertise, your client demand, and your profit margins. Don't guess. Actual scoring. Then you'll see whether this is a real opportunity or just shiny distraction. Then make a call. But make it based on data, not intuition.
