Profit tracking
How to track profit for reselling
Profit tracking gets easier when every sale stays tied to the item, the payout, the fees, and the costs around it.
Quick take
- Start with sale price, but do not treat it as profit.
- Track item cost, marketplace fees, shipping, supplies, refunds, mileage, receipts, and other expenses before the details get stale.
- Use Resylr when you want profit tied to inventory, listings, orders, receipts, mileage, finance, and tax-ready records.
Steps
- 1
Start with the sold item
Connect every sale to the original inventory record, SKU, bin, source, purchase date, and item cost.
- 2
Record the full sale
Keep sale price, marketplace, order date, payout, buyer-paid shipping, seller-paid shipping, discounts, refunds, and order status together.
- 3
Subtract all selling costs
Track marketplace fees, payment fees, shipping labels, supplies, promotions, returns, mileage, and other business expenses that changed the real margin.
- 4
Review net profit by pattern
Compare profit by marketplace, category, source, item age, average sale price, and repeat cost so weak inventory is easier to spot.
- 5
Keep records exportable
Use organized records for review with bookkeeping, accounting, or a qualified tax professional.
Use this simple profit formula
For day-to-day resale decisions, start with sale price, subtract item cost, marketplace fees, shipping, supplies, refunds, mileage, and other expenses, then review the net profit left over. The exact tax treatment can depend on your facts, but this workflow keeps the business record cleaner.
Gross sales are only the top line
Marketplace dashboards can show what buyers paid, but that number does not explain what you kept. eBay says final value fees are based on the total sale amount plus a per-order fee. Poshmark's fee policy says sales under $15 have a flat fee and sales $15 and above use a percentage fee. Mercari says new or updated listings have a seller fee based on item price and buyer-paid shipping.
COGS and expenses are different records
The IRS small business guide discusses cost of goods sold and gross profit separately from other business expenses. For resellers, that means item cost, inventory value, shipping supplies, selling fees, mileage, and software should not be tossed into one vague bucket.
Track profit close to the sale
The best time to finish the profit record is when the order is still fresh. Waiting until month-end or tax season makes refunds, shipping discounts, promoted listing costs, missing receipts, and partial payouts harder to explain.
- Sale price, payout, marketplace, order date, and item status.
- Cost of goods, source, SKU, bin, and purchase proof.
- Marketplace fees, payment fees, shipping label cost, supplies, and refunds.
- Mileage, receipts, sourcing costs, storage, software, and other business expenses.
- Net profit by item, marketplace, category, source, and month.
Profit tracker apps can help, but context matters
Compare what happens after the listing goes live. They can help sellers see margin faster. Resylr fits when profit should stay tied to listing drafts, crosslisting, sync, inventory, orders, labels, receipts, mileage, finance, and tax-ready reports.
Where Resylr fits
Resylr keeps Profit Calculator, inventory, orders, labels, finance, receipts, mileage, consignment statements, and tax-ready reports close to the listing workflow. That makes profit tracking part of daily selling instead of a separate cleanup spreadsheet.
