How it works
A guided tour of your booth
A short walkthrough covering everything you do at the fair, from check-in to ROI. Designed to be picked up in minutes, not hours.
-
01 · Catalog
FreeBuild your catalog once, find anything in seconds
Add products in three taps and search by name, language, set, EAN or grading slab. The A–Z scroll rail keeps the catalog usable even with thousands of items.
- Five product types: card, graded, sealed, merch, generic
- Photos, conditions, optional purchase price for analytics
- Live search + filters tuned for fair-floor speed
-
02 · Add product
FreeAdd a new product without leaving the till
A focused form with type-specific fields, barcode scan, photo capture and optional purchase price. Save and you’re back to the catalog ready to sell.
- Barcode scan auto-prefills the EAN — no typing
- Type-specific fields: language and condition for cards, grading slab for graded
- Optional purchase price kept private, used only for your margin
-
03 · Live POS
FreeSell with cash, card, trade credit — even mixed
Open a cash session, ring up sales, park carts when a customer says "I’ll be back with my card". Touch targets sized to be hit on the run, not at a desk.

- Mixed payments at checkout (cash + trade credit + card external)
- Parked carts and ghost items for bulk sales

04 · Trade-in

Show the customer two adjustable offers (cash and store credit) and apply the one they pick directly at the next checkout. No mental math, no "wait, can I see that again".
- Independent withhold sliders for cash vs. store credit
- Photo capture of the trade-in to prevent disputes
- C2C declaration PDF on Pro for cross-border fairs
