What is proposed
Six small things that sit outside the dashboard and follow a dealer into the rest of their working week.
A verified badge for a dealer's own website, generated from their handle and checkable against Worldwatch. An email signature carrying the same mark. A provenance record for a sale, issued as a document the buyer keeps and anyone can verify afterwards. A printable buying form for purchases made away from the shop, at a fair or across a hotel lobby. A physical member kit posted to the shop. Wallpapers, which is the least useful of the six and the easiest to build.
The badge is the one worth doing first. Verification is the part of membership that a dealer's own customers can see the value of, and at the moment it is visible only to other dealers.
What ships today
The product itself, which is a larger claim than any of the above. Inventory, listings pushed to connected channels, orders, and the market. Features covers what the application does, and integrations covers the channels a dealer can connect: eBay, Shopify, WooCommerce, Wristler and Bezel.
If one of the six above would change your week, say which. It is a short list and the order is not fixed.
