Ask a vendor how last Saturday's market went and you'll usually get a vibe, not a number: "it was busy," "kind of slow," "eh, it was fine." Vibes are not data. The vendors who build a real income from craft fairs and farmers markets are the ones who know, event by event, exactly what came in and what went out. Everyone else is guessing, and guessing means applying to the same underperforming markets year after year because they felt good, not because they paid.
This is the method for fixing that: what to track, how to track it without turning your Saturdays into spreadsheet homework, and how to use a season of your own numbers to stop applying to the wrong events. It also covers VendorsMap's My Markets tool, which was built to do this tracking for you, but the method works just as well with a notebook.
Why "it felt busy" is the wrong measurement
Foot traffic and revenue are correlated, not identical. A packed farmers market with families browsing for produce can easily out-traffic a smaller craft fair while under-earning it, because the crowd came for tomatoes, not $60 pottery. A market can feel dead by 11am and still be your best day of the month because the three people who did show up bought everything you had. The only way to know which is which is to write down what actually happened.
The four numbers that matter
You don't need complicated bookkeeping. Per market, per day, track:
- Booth fee. What you paid to be there, including any electricity or corner-spot upcharge.
- Gross sales. Everything that came in at the table, cash and card combined.
- Net. Gross minus booth fee. This is the number that actually tells you whether the day was worth it.
- Event type and location. Farmers market, craft fair, festival, or pop-up, plus the city or region. This is what lets you compare categories later, not just individual events.
Net here means gross minus booth fee, not gross minus every cost of doing business. It doesn't account for materials, gas, or your time, and for this purpose it doesn't need to. Full profit math, the kind that includes cost of goods and mileage, is worth doing occasionally, and we cover it in our breakeven guide. But booth-fee-adjusted net is the fastest apples-to-apples number for comparing one market against another, because booth fee is the cost that varies most between events and is entirely known in advance.
Log it the same day, not the same month
The single biggest reason vendors stop tracking is that they wait too long. Two weeks after an event, you remember "it was decent" but not the actual total. The habit that sticks: log the number before you leave the parking lot, or that night while you're unloading. Thirty seconds per event is the entire cost of this system. If you use My Markets, logging a market you already worked takes one short form: event name, date, location, booth fee, and gross sales. It computes net automatically, and it's the same 30 seconds whether you use a notebook or the app.
What the pattern looks like after a season
One market tells you almost nothing. Eight to twelve tell you a lot. After a season of logging, three views start to matter.
By event type
This is where most vendors get surprised. A vendor selling $30 to $60 handmade goods might find their craft fairs average $650 net while their farmers markets average $320 net, roughly two to one in favor of craft fairs, even though the farmers markets "felt" steadier week to week. The farmers markets weren't a bad use of time (a reliable $320 every Saturday adds up), but if booth space and application time are limited, the pattern tells you where to put your applications first.
By region
The same product can perform differently 40 minutes in one direction versus another, for reasons that have nothing to do with distance: income levels, whether the crowd skews tourist or local, whether three other vendors selling something similar to you are also regulars there. If your logged markets in one county average $500 net and a neighboring county averages $280 net at similar booth fees, that's worth knowing before you fill next year's calendar with the county that's actually underpaying you.
Best and worst, side by side
Once you have enough data, the honest question becomes: would you have applied to your worst-performing market if you'd known its number in advance? Usually not. Vendors keep booking events out of habit, loyalty to an organizer, or because it's the one they've always done, long after the numbers say to stop. Seeing your best and worst market side by side, with real net figures, makes that decision much easier to make without the guilt.
Turn the pattern into where you apply next
The point of tracking isn't the spreadsheet, it's the next booking decision. Once you know your top-earning event type and region, the useful move is to find more markets that match that pattern rather than more markets in general. If craft fairs in your region are your best net category, look specifically for more craft fairs in that radius rather than applying broadly to whatever shows up next. My Markets does this directly: once you've logged enough markets, it points you back to the map, already filtered to your best-performing event type and area, so your next application is aimed at the pattern that's already working instead of a guess. For the method behind setting up that kind of ongoing search, see how to find the right markets to sell at.
The honest catch
None of this works if you don't log the numbers. It's tempting to skip it on a slow day (nothing to be proud of) or a busy day (too tired to type numbers in). Both are exactly the days you need most, because slow days and busy days are the ones that actually move your averages. Pick one habit, whether that's a notes app, a spreadsheet, or My Markets, and commit to logging every market for a full season before you draw conclusions. Six data points is a hunch. Twelve is a pattern you can act on.
Once you have that pattern, use it. Apply less to your bottom half and more to markets that look like your top half.

Then start logging your own.
