A reseller profit and loss statement should answer one question: after the item cost, selling fees, shipping, returns, supplies, and overhead, did the business actually make money?

That is harder than it sounds when eBay, Poshmark, Depop, Mercari, Etsy, Whatnot, and local sales all report payouts differently. Some payouts already remove platform fees. Some do not show your original item cost at all. None of them know what you spent on sourcing trips, storage bins, labels, tape, repairs, software, or receipts sitting outside the marketplace.

P&L rule for resellersDo not start with “what hit my bank account” and call it profit. Start with sold-item revenue, connect each sale to its item cost, then subtract the selling and operating costs that made the sale happen.

Simple reseller P&L structure

P&L lineWhat to includeReseller note
Gross salesItem sale price, buyer-paid shipping, bundle revenue, local cash salesKeep marketplace taxes separate when the platform collects and remits them.
Refunds and discountsReturns, partial refunds, offers, coupons, cancelled ordersTrack these against the item so bad buys are visible.
COGSCost basis for sold items, allocated lot cost, repair cost tied to an itemUnsold inventory is not the same as sold-item COGS.
Selling costsFinal value fees, commission, processing, promoted listings, labels, shipping adjustmentsSeparate marketplace fees from postage and supply costs when possible.
Operating expensesSupplies, storage, software, mileage, sourcing trips, cleaning, photography, subscriptionsThese costs can make a high-margin item less profitable than it looked.
Net profitGross sales minus refunds, COGS, selling costs, and expensesThis is the number to review by month, platform, source, and category.

Worked reseller P&L example

Imagine a clothing reseller sells 32 items in a month across eBay, Poshmark, and local pickup. The marketplace dashboards show revenue, but the P&L needs the full cost trail.

Gross sales$1,860.00
Refunds and discounts− $115.00
Sold-item COGS− $520.00
Marketplace fees and promoted listings− $278.40
Shipping labels and adjustments− $164.25
Supplies, storage, software, and sourcing mileage− $221.35
Net reseller profit$561.00

The useful part is not just the final $561. It is seeing which costs caused the change: refunds, COGS, promoted listings, shipping, and overhead are all separate enough to fix next month.

Reseller P&L FAQ

What is the difference between reseller revenue and profit?

Revenue is what buyers paid before the full cost stack is deducted. Profit is what remains after refunds, sold-item cost, marketplace fees, shipping, supplies, overhead, and other expenses.

How often should resellers review a P&L?

Monthly is a practical rhythm for most resellers because it catches fee, sourcing, shipping, and stale-inventory problems before tax time.

Is stokd tax filing software?

No. stokd helps organize the item, sale, fee, receipt, and expense records that support cleaner profit tracking. Ask a qualified tax professional how tax rules apply to your business.
