Seller features

Everything a live MTG seller needs before, during and after a show.

Toploader OS brings the repetitive parts of live selling into one fast, seller-first desktop workflow.

Exact card print matching

Search Scryfall variants, save set codes, collector numbers, images, finishes and special foil treatments so the right version of each card is listed.

Foil treatment awareness

Handle foil, etched, surge, galaxy, textured, raised, neon ink and other treatments separately instead of flattening every shiny card into one generic foil bucket.

Market-percentage pricing

Set selected singles to a chosen percentage of saved market price for sellout streams while preserving the original reference market value.

Inventory profiles

Separate workspaces for different stock pools, with their own sales, images, shows, snapshots and export history.

Whatnot CSV exports

Prepare marketplace-ready titles, descriptions, quantities, prices, conditions, shipping profiles and public image URLs.

Sales analytics

Track gross revenue, payouts, net profit, items sold and stock snapshots after the show instead of guessing from disconnected files.

Break and event tools

Build pack breaks, surprise sets, bundles and event pools with Whatnot fee math baked into the target price.

Reconciliation memory

Map Whatnot sold item names back to your inventory, deduct stock and remember mappings for repeat shows.

Free and Pro modes

Let new sellers start free, then unlock advanced workflows with a Lemon Squeezy licence key when the business needs it.

FAQ

Questions sellers ask before installing.

Is this only for Magic: The Gathering?

Toploader OS is tuned for MTG singles because of Scryfall print data, but the inventory, sealed, accessories, show builder and seller tools can support broader trading-card workflows.

Does it connect directly to Whatnot?

The app prepares Whatnot-focused CSV exports and reconciliation workflows. You still control uploads, listings and sales activity in your Whatnot seller account.

How does Pro activation work?

Pro uses a Lemon Squeezy licence key. After purchase, customers activate the key inside the desktop app to unlock advanced workflows.

Can I keep using my own SEO plugin?

Yes. This theme outputs basic metadata only when a major SEO plugin is not detected, so Yoast, Rank Math or AIOSEO can take over cleanly.

Ready for your next show?

Spend less time preparing listings and more time selling cards.

Download the latest build, test the workflow, then unlock Pro when you are ready to run faster Whatnot shows.
