KPIs for makers: how to tell whether a workshop is really working

Many makers run their workshops 'by gut feeling': this one seems to be doing fine, that one maybe less so. Gut feeling is precious, but on its own it deceives you. A few simple numbers, looked at regularly, tell you things instinct can't see: which workshop is worth pushing, which one is quietly losing money, where people stop short of booking. You don't need complicated spreadsheets or analyst skills: a handful of clear, honest indicators (KPIs, key performance indicators) is enough.

The goal isn't to turn you into an accountant, but to give you a compass. Measuring a few of the right things helps you make better decisions and stop relying on the impression of the moment.

The fill rate

This is perhaps the most important number: how many seats you sell out of those available. A workshop with 8 seats that fills an average of 3 has a low fill rate, and that changes everything — your earnings per session, but also the atmosphere (a group that's too small can sometimes 'kill' the experience). Keeping an eye on the average fill rate of your workshops tells you which ones are genuinely in demand and which aren't, regardless of how much you like them. A consistently low fill rate is a signal: maybe the price, the time slot, the description or the demand aren't aligned.

Real earnings per session

Not the ticket price, but what you actually keep after costs (materials, any fees, your time). A workshop that takes in more but costs a lot in materials can earn you less than a more 'modest' but efficient one. Working out your real earnings per session, even roughly, lets you compare your workshops on honest grounds and discover that your favourite might not be the most profitable — valuable information for deciding what to focus on.

The clients who come back and recommend you

How many of your participants come back for a second workshop? How many show up because someone sent them your way? These two numbers tell the deep health of your business. A high return and word-of-mouth rate means the experience is genuinely good and you're building something solid; low figures, even with plenty of new bookings, are a warning sign: you're filling a leaky bucket, forever having to find new clients because the old ones don't come back.

Where people drop off (the conversion rate)

If lots of people look at your workshop page but few book, the problem isn't demand: it's something in the listing, the price or the trust. Even without sophisticated tools, you can spot signals: do you get lots of questions but few bookings? do people stop at the payment step? Understanding where the journey breaks down tells you where to act, instead of changing everything at random.

From numbers to decisions

KPIs are little use if they don't turn into action. Low fill rate on a workshop? Try changing the time slot, price or description before scrapping it. Disappointing real earnings? Review your material costs or the price. Few returning clients? Work on the experience and the post-workshop relationship. Lots of visits but few bookings? Fix the listing. The numbers aren't a verdict on your worth: they're clues that tell you where to act in order to grow.
