Every copy has a condition, a cost, a price and a box it lives in. The listing is built from that, the sale writes back to it, and the profit report says how much of your shelf it actually covers.
Every copy with its own condition, cost, asking price and storage location, grouped by set with the photo you took of it. Quantity on hand and quantity reserved are separate numbers, so a card committed to a live listing cannot be sold twice. Sealed boxes, packs, supplies and memorabilia sit alongside the singles.
Not one card, one listing. Build a variation listing where every printing of a card is one page with a dropdown, or a mixed lot from whatever you select. Duplicates are combined for you as the draft is built, and each physical copy keeps its own storage location underneath, so when something sells you know which box to open.
Start price, an optional reserve, and a 3, 5, 7 or 10 day run, set on the draft here rather than on eBay afterwards. Best Offer with automatic accept and decline thresholds, as an amount or a percentage of the price.
Write a title and description template once, with variables for the card, set, number, condition, finish and grade, and every listing follows it. Or keep ours. A line whose variables are all empty for a given card is dropped rather than left hanging.
The front, the back, the two side by side, and a zoom of each corner — built from your own photographs, never from catalog art. A lot gets every card's photo, tiled into contact sheets when there are more than eBay's twelve.
Scan the label, take the money. Cash is recorded on the spot; for card payment the buyer scans a QR and pays on their own phone. The sale decrements stock and ends the matching eBay listing, so the same card cannot sell twice in one afternoon.
Price labels for your own stock: thermal rolls or Avery sheets, your own logo, and you choose which fields appear. The barcode and the QR encode the same value, so either one scans at checkout.
Build a packing list before the show, print labels from it, sell from it at the table, then see whether the table paid for itself, with the table cost and the travel included. That is the part most people leave out.
Market value, cost basis and unrealised profit, each printed with the share of your inventory it is actually based on. A partial total is labelled as one rather than passed off as complete.
Your own cards ranked by what grading would net after the fee, judged on the PSA 9 where the realistic outcome already pays and on the PSA 10 only where the gem is the sole thing paying. Those two are marked differently, because one is a decision and the other is a bet.
Players ranked by how many of their cards changed hands in the last 24 hours or seven days, and the median each one sold for. Completed sales, not listings, and the footnote says how big the sample was.
Follow a player, a card or a set over time. The window adapts to how fast the thing actually trades, so a slow vintage card is read over a longer stretch than a card selling fifty times a day.
What is coming and when, across trading cards and sports, so buying can be planned before a set lands rather than after. Add a release to your own calendar in one tap.
Your binder and your inventory out to a spreadsheet whenever you want them, and they open correctly in Excel including every accented name.
