Inventory built for selling, not just collecting
MTG inventory software for Whatnot sellers
Track Magic singles, sealed boxes, booster packs, graded cards and accessories — plus Pokémon singles — with the metadata you need for pricing, shows, exports and reconciliation.
Exact printings
Multiple inventories
Needs-attention flags
Stock analytics
Inventory database
Track the stock that actually appears in your shows.
Toploader OS supports more than one kind of trading-card inventory, so your live-selling stock does not have to be forced into a card-only spreadsheet.
Single cards
Use Scryfall search to pick exact printings, finishes and foil treatments, then save card images and market metadata.
Sealed products
Track booster packs and sealed boxes with cost, packs per box, target margin and pack-level pricing.
Accessories and products
Add sleeves, deck boxes, playmats, toploaders, storage, dice, tokens, bundles, graded cards and other seller products.
Inventory profiles
Separate different stock collections into profile workspaces with their own inventory, sales, shows and export history.
Search and filters
Search by name, set code, collector number, artist, finish, type, rarity and other stored metadata.
Stock health checks
Surface missing images, missing prices, zero quantity, below-cost products and ready-for-Whatnot rows.
Why exact printings matter
Magic cards can vary by set, collector number, finish and special foil treatment. Toploader OS stores the exact data needed to list and price the card you actually hold.
Set name and set code for clearer listing titles.
Collector number for easier buyer verification.
Finish and special treatment labels for foil, etched and other treatments.
Saved image URLs and local image copies for previews and exports.
Inventory workflows

Bulk workflows
Use Pro bulk edits and market-percentage pricing to adjust many selected lines.
Analyse stock
Review total value, cost basis, estimated payout, estimated profit and attention flags.
FAQ
Inventory software FAQs
Can I import from ManaBox?
Yes. The ManaBox import workflow scans CSV rows, previews valid and failed entries, handles duplicates and can save import reports.
Can I track sealed boxes and packs?
Yes. Sealed Box and Booster Pack are core product types with their own cost and margin pricing flow.
Can I manage accessories?
Yes. The app includes product types for sleeves, deck boxes, playmats, storage, toploaders, card stands, dice, bundles and more.
Does changing stock reprice old inventory?
Quantity-only stock adjustments are designed not to touch saved cost, margin, VAT or sale price fields.
