For a year and a half, I ran a small dropshipping beauty brand on Shopify and paid TrueProfit every month to tell me whether I was making money. I trusted the number it gave me. That was the mistake.
The first thing that broke my trust was chargebacks. When I was using TrueProfit through 2024, my bank was charging me $15 every time a customer disputed a charge — even when I won the dispute and got the money back. The dashboard didn't surface those fees as a cost line, and it didn't track whether a given dispute had been won or lost; as far as it was concerned, a chargeback was a refund, full stop. I'd close out a month thinking I'd cleared a healthy margin and find an extra few hundred dollars of fees sitting on my Shopify Payments statement that no P&L had shown me.
The second thing was bundles. I sold beauty products in three-item kits. My supplier shipped them together — one box, one shipping fee. The math was simple: $4.20 to ship a single product, $6.80 to ship a three-pack. TrueProfit added up the COGS of each item correctly, but it billed shipping per line item — so my P&L was charged $4.20 × 3 = $12.60 in shipping for an order that actually cost me $6.80. That's $5.80 of phantom cost on every three-pack I sold. Multiplied across the bundles I moved in a month, it was the difference between a healthy line and a marginal one.
