Run your shop on the same numbers your customers do.
The same source-honest comps your customers see, wired into your POS, share pages, and accounts. Sits next to the till — tells you what you should have asked for.
Cost basis per SKU. Sell-through by day, week, month. Weighted margin by set. A P&L that ties to your books. Export to CSV at month-end, hand it to your accountant, sleep.
All inventory operations flow through the existing OwnedCard model — no separate dealer schema. Your binder and your shop run on one ledger.
Shopify, Square, Zapier, n8n, your own back-office. Every spike, sell-candidate, and verdict fires as a signed webhook. Re-price automatically, flag in Slack, or roll up nightly into your warehouse.
Branded with your logo, served from your subdomain (lots.yourshop.com). Customers see your inventory at your prices. No "powered by" badge, no third-party chrome.

Letter from a dealer
“We were running three spreadsheets, two pricing tabs, and a paper notebook for grading queue. One of those was for VAT. Poketrax replaced all of it. The margin report alone has been worth the year.”
