What you get

Built for shops moving thousands of unique cards a week.

The tools we wish we had when we were running the back room of a card shop. Four pillars, designed to replace the spreadsheets and the stitched-together tools that most retailers still rely on.

01

Unify multi-game SKU management

Pokémon, Magic, Yu-Gi-Oh!, Disney Lorcana, One Piece, Riftbound, and sports — one canonical catalog, one identifier system, no parallel spreadsheets.

02

Pricing grounded in recent sale comps

AI-assisted pricing suggestions reference the last 14 days of comps across marketplaces, weighted by condition, language, and channel-specific fees.

03

Cross-channel inventory in minutes

A card scanned at the back-room bench can be live on eBay, TCGplayer, Shopify, and Cardmarket — with one source of truth and conflict resolution.

04

Reorder analytics & liquidation routing

Slow-moving sets get routed to the channel with the highest realized margin. Restock suggestions drop automatically when sell-through crosses the threshold you set.

How it works

From catalog import to live listings in three steps.

Most retailers are running Stackwise inside a week of onboarding. The bottleneck is usually your data quality, not the tooling.

Book an onboarding call
  1. 01

    Connect your catalog and channels

    Import from spreadsheets, POS exports, or directly from TCGplayer / Shopify APIs. Stackwise dedupes and reconciles condition, edition, and language in one pass.

  2. 02

    Scan, list, price in one motion

    Bench scans create draft listings with AI-suggested prices grounded in sale comps. Approve, edit, or auto-publish — your call, per game or per SKU class.

  3. 03

    Watch velocity, route liquidity

    The dashboard surfaces sell-through drift, reorder signals, and dead stock before it eats margin. Liquidation is a routing decision, not a panic move.
