The problem with waiting I've sat with people running their own thing who swear everything is fine right up until it isn't. They'll tell me their numbers look okay, their customers seem happy, they're still getting work. Then three months later they're scrambling because something fundamental shifted and they didn't see it coming. The brutal truth is this: by the time you feel the problem, you're usually already in it. I'm not talking about sudden crashes. Those are actually easier to spot. I'm talking about the slow erosion. The business model that worked brilliantly for two years but is now working less brilliantly, and you're too close to it to notice. You're too busy running the thing to observe it. What actually matters Forget revenue for a second. Revenue can stay flat or even grow while your model dies. I've seen it happen. A business owner in London I worked with through ALIRA had flat revenue for six months and thought things were stable. Turns out his customer acquisition cost had crept up 34% because his referral channels had dried up. He was replacing lost customers with expensive ones. The top line looked fine. The model was broken. So what do you actually need to watch? First, your unit economics. This is the cost to deliver one unit of whatever you sell versus what you make from it. Not profit margin on a sale. The actual cost to acquire that customer, serve them, keep them happy. If this number is getting worse, your model is degrading. Full stop. Second, your repeat customer rate. Or in B2B terms, your renewal rate. If this is declining, something in your offer or service has shifted. People don't suddenly stop coming back for no reason. They come back when they get value. When they stop, you've either changed what you deliver or the market has changed what it needs from you. Third, how much time you're spending on things that don't make money. I mean actual hours. Not a feeling. If you're spending 25% of your week on admin that didn't exist six months ago, your model has changed. You've added friction. That friction will compound. Fourth, your customer acquisition channels. Are they as efficient as they were? Can you still reach people the way you used to? This matters more than you think. I've watched good businesses die because they relied on one channel, that channel got saturated or changed algorithm, and they didn't build alternatives in time. The geopolitical angle (and why it matters to you) Look at what's happening in the news right now. Oil prices spiking, supply chain threats from Iran and pork industry disruptions in Spain, wage changes from the two-child benefit cap ending. These aren't just headlines. They're signals about what's about to change in operating costs, labour availability, and customer spending patterns. If you run a delivery business, fuel costs matter. If you hire, the benefits changes mean some of your potential workforce just got £4,100 a year more in household income. That changes hiring dynamics. If you work with manufacturers or food businesses, the pork industry disruption is a sign that import-dependent supply chains are fragile. The point is this: your business model doesn't exist in a vacuum. When external conditions shift quickly, your model can break before you realise the ground has moved. The people who spot this early do one thing. They watch the conditions outside their business as carefully as they watch what happens inside it. How to actually check Pick three metrics. Not ten. Three. For most small businesses, that's something like: customer acquisition cost, repeat purchase rate, and gross margin per customer. For service businesses, it might be: billable hours per week, client retention rate, and time spent on admin versus billable work. Measure these every month. Not quarterly. Monthly. You don't need fancy software. A spreadsheet works. What you need is the habit of looking. Then ask yourself one question each month: are these getting better, worse, or staying the same? If two of your three metrics are moving in the wrong direction, your model is changing. That's not a maybe. That's a fact you need to act on. Don't wait for revenue to drop. By then you're reacting instead of steering. The speed factor Here's what I've learned: the faster your business changes, the more frequently you need to check. If you run a seasonal business, monthly checks matter. If you're in a volatile market like energy trading right now (which is having a rough time with Middle East instability), you might need weekly checks on key metrics. If your model is stable and mature, monthly is fine. But the moment you feel uncertainty, increase the frequency. That feeling is real. Your gut is picking up on something your spreadsheet hasn't confirmed yet. What to do this week Monday morning, write down your three key metrics. The ones that would tell you if your model is actually working. If you're not sure what those are, use ALIRA's Decision Matrix tool to figure out which metrics matter most to your specific business. Then pull your numbers for the last three months. Yes, today. Not next week. Spend 20 minutes on this. See if they're moving the direction you want. If you don't have the numbers readily available, that's also a signal. Fix that this week. Finally, set a monthly check-in date. Same day each month. Thirty minutes. Numbers, three questions, done. Calendar it now so you actually do it.
