## On Deck by MDC Description
On Deck by MDC is an inventory, sales, and show-prep platform built for trading card collectors, vendors, and hobby sellers.

Manage raw cards and graded slabs, organize collections, track cost and market value, prepare inventory for shows, build trades and bundles, and keep sold cards organized — all from one connected inventory.

Whether you collect, sell locally, vend at card shows, or sell online, On Deck gives you a faster way to manage your cards without relying on spreadsheets.

FEATURES

• RAW & GRADED INVENTORY
Track raw cards and graded slabs with card details, cost, market value, grading information, certification numbers, and collection data.

• COLLECTION MANAGEMENT
Create and organize collections while keeping your inventory searchable and easy to manage.

• ON DECK SHOW PREP
Move cards into your active selling lineup and quickly access the inventory you plan to bring to a show.

• VENDOR MODE
Prepare cards for in-person selling, manage show inventory, view pricing targets, and use customizable QR price labels.

• TRADE & BUNDLE TOOLS
Build multi-card deals and trades while viewing individual and combined market values.

• PRIVATE SALES
Create a shareable sales catalog from your inventory, add card images, receive buyer inquiries, and manage potential deals.

• EBAY MODE
Estimate selling fees, shipping costs, and expected take-home amounts before listing or accepting an offer.

• COST & MARKET TRACKING
Compare what you paid against current market values so you can better understand inventory value and margins.

• SOLD CARD TRACKING
Record sales while keeping transaction information connected to your inventory history.

• FAST SEARCH & FILTERING
Quickly find cards across your inventory and collections.

• QR & CAMERA WORKFLOWS
Use scanning tools to speed up inventory management and card access.

• CLOUD SYNC
Your inventory is connected to your account and available across supported devices.

On Deck by MDC was built around the actual workflow of collectors and card sellers — from adding a card to inventory to preparing for a show, making a trade, or completing a sale.

Spend less time managing spreadsheets and more time working with your collection.
