Why resellers who track their numbers make more money

April 7, 2025

Ask most resellers what their margin is and they'll give you a rough guess. Ask them which category is most profitable and they'll say "probably jackets." Ask them whether their last market day made money after the stall fee, and most can't tell you.

This isn't a criticism. Running a reselling business is operationally chaotic. You're buying, listing, shipping, sourcing, managing platforms, all at once. Tracking feels like overhead. But not tracking is costing you money in ways you can't see.

What actually changes when you track

You stop selling things at a loss. Platform fees, shipping labels, and packaging add up. A pair of jeans listed at $40 with a $6 shipping label, $4 in platform fees, and $3 in packaging nets you $27. If you paid $22, that's $5, not $18. Once you see the real numbers, you price differently.

You find out which categories actually perform. Most resellers have a category they think is their best and a category they're wrong about. The data is almost always surprising. Tracking forces the truth.

You know whether markets are worth doing. Stall fees, travel, time, and unsold inventory all factor in. Some market days are genuinely profitable. Others are a wash or worse. You can't optimise what you don't measure.

Tax season stops being painful. COGS, revenue, platform fees, and shipping costs, logged throughout the year, means your tax prep takes hours instead of weeks. Reselling is a business. Treat it like one.

The minimum you need to track

You don't need a complex system. At minimum: what you paid, what you sold for, the platform, and the date. That's enough to calculate real profit, identify trends, and make better sourcing decisions. Everything else builds on that foundation.

That's the entire premise behind Hauly. Start simple, get the data, make better decisions.
