Which expenses eat into profits the most—and how can I minimize them?
Strong sales can still end in weak take-home pay if the biggest costs stay hidden, so the goal is to spotlight the heaviest expense buckets and shrink them on purpose.
The Narrative (Left Column)
The Empathy
Market day ends with a full cash box and a phone buzzing with card deposits, but once you add up the booth fee, materials, gas, and that last-minute run to the supply store, the profit feels tiny. It's frustrating because the sales looked great on the surface, yet the real payout doesn't match the effort. When expenses live on scattered receipts, it's easy to miss the biggest leaks.
The Education
The largest expense categories usually fall into five buckets: inventory and materials (cost of goods), market fees and commissions, payment processing charges, travel and setup costs, and labor time (including your own hours). Inventory and materials can quietly spike when you buy small quantities or toss damaged goods. Booth fees and commissions shrink every sale before you even start. Card fees and app charges add up across dozens of small transactions. Travel, parking, and setup supplies chip away at each event. And if you ignore the value of your time, it's easy to think you're profiting when you're really working for less than minimum wage.
The Solution
A simple tracking routine makes the biggest costs obvious. Break expenses into those five buckets after each event so you can see which category is climbing. To reduce inventory costs, batch-produce best sellers, buy supplies in bulk with trusted vendors, and trim slow-moving SKUs. To lower fees, compare markets by net profit per hour and skip the ones that require high commissions for low traffic. To limit payment charges, encourage cash or low-fee options on small purchases and negotiate rates once your volume grows. To manage travel and setup costs, carpool with vendors, pack reusable signage, and plan inventory so you aren't making emergency supply runs. Finally, protect your time by setting realistic prep hours and baking a labor target into pricing. When you see expenses by category, you can choose the changes that turn busy sales days into real profit.
