One inventory. Every place you sell.
Lockstock is the control room behind your card business — online and at the table. Here's what it actually does.
Never oversell again
Sell the same card on eBay, TCGplayer, your storefront and in person off a single stock count. The second it sells anywhere, Lockstock pushes the new quantity to every other channel — or ends the listing — automatically.
- One canonical quantity behind every listing
- Sales pulled in by API and reconciled in seconds
- Out-of-stock or end-listing — your call, per channel
Run your booth from an iPad
Bring your inventory to a show without bringing a spreadsheet. Print QR labels, scan a card to ring it up, take payment, and your online stock drops before the next customer steps up.
- Configurable QR price labels (2×1 and up)
- Scan with a Bluetooth scanner or the camera
- Take Cash · Venmo · Cash App · PayPal · card
- Every in-person sale syncs to your channels
Stay at market, never below your floor
Lockstock prices each card to the live market so you don't have to babysit it — anchored to real data, with a floor you set so you're never undercut into a loss.
- Price to live market, automatically
- A hard floor that bakes in your costs
- Market Movers: see what's heating up before you restock
