Plain-English reseller terms

The eBay reseller glossary you can actually use.

Pricing, fees, inventory, lots, shipping, and profit terminology explained around the decisions sellers make every day.

A working draft

Reselling from A to Z

These definitions match how Strooply organizes research, listings, costs, and financial results.

Research and pricing

Active listings
Comparable items currently offered for sale. They show competition and asking prices, but not what buyers actually paid.
Average sold price
The average price paid across a set of relevant sold listings. It is most useful when poor matches and unusual outliers are removed.
Market research
The process of identifying an item, reviewing active competition and sold results, then deciding whether the expected price and sales speed justify buying or listing it.
Sales velocity
How quickly comparable inventory sells. Strooply uses recent market activity to help distinguish a fast mover from an item that may sit for months.
Sell-through rate
A demand signal comparing sold results with available listings. A higher rate generally means stronger demand, but the quality of the matches still matters.
Sold comps
Recently sold listings for the same or a closely comparable item. Condition, model, size, completeness, and quantity should be considered before treating a result as comparable.

eBay listings

Condition notes
A factual description of wear, damage, missing parts, testing, and other condition details that a buyer should know before purchasing.
Draft listing
A listing being prepared but not yet published. In Strooply, AI can fill a draft, but the seller reviews and confirms it before anything goes live.
Item specifics
Structured eBay fields such as brand, model, size, color, material, and type. Accurate specifics help buyers find and filter a listing.
Listing title
The searchable headline for an eBay listing. Strong titles prioritize exact product identity and useful attributes instead of filler words.
SKU
A seller-defined stock keeping unit used to identify and locate inventory. A SKU can encode a bin, shelf, category, or another system that works for the seller.
UPC, EAN, or ISBN
Standard product identifiers that can make identification and category matching more reliable when they are present and accurate.

Costs, fees, and profit

Buyer-paid shipping
The amount charged to the buyer for shipping. It contributes to gross revenue, while the shipping label is a separate expense.
COGS
Cost of goods sold: the purchase cost assigned to the inventory that actually sold. For a lot, the cost may need to be allocated across its units.
eBay payout
The amount eBay sends after marketplace deductions. Strooply uses the actual payout when available rather than continuing to rely on fee estimates.
Gross revenue
Sale price multiplied by quantity, plus shipping paid by the buyer. It is the top-line amount before costs and fees are deducted.
Lot cost allocation
Dividing a bulk purchase cost across the sellable units it produced. If six items cost $60, the starting allocated cost is $10 per item.
Net profit
Proceeds remaining after COGS, shipping labels, promoted listing charges, other fees, refunds, and return shipping are deducted.
Profit margin
Net profit divided by gross revenue. It answers: how much of each revenue dollar remained as profit?
Promoted listing fee
An advertising charge associated with an eBay sale attributed to a promoted listing campaign. It is separate from standard transaction fees.
Return on cost
Net profit divided by COGS. Resellers often call this ROI, though it specifically measures return against inventory cost.
Shipping label cost
The actual postage purchased to send the order. It should not be confused with the amount charged to the buyer.
Transaction fees
Marketplace charges associated with processing the sale. Rates vary, so settled order data is more reliable than a universal percentage estimate.
Refund and return cost
Money returned to the buyer plus any return shipping expense. Both can change the lifetime profit of an item that is later relisted and sold again.

Sourcing and operations

Consignment split
The agreed percentage or amount owed to an inventory owner after a sale. The split should be applied to a clearly defined profit or proceeds base.
Inventory location
The physical place where an item is stored, such as a shelf, bin, room, or warehouse area.
Lot
A group of items purchased together for one combined price. Items may later be listed separately, bundled, or sold in different quantities.
Receipt allocation
Connecting a receipt line to the item or lot it purchased so the correct acquisition cost flows into inventory and profit reporting.
Sourcing trip
A buying trip that can group stops, inventory acquisitions, mileage, and receipts into one operational record.
Stock quantity
The number of sellable units held. Quantity sold and quantity remaining must be separated for accurate cost and inventory tracking.

Turn the terms into a repeatable workflow.

Research an item, save a draft, assign its real cost, publish to eBay, and see what remained after the sale.
