Made for the phone in the shopper's hand

Questions

Good to know

Is there a free trial?

Yes. Send us a request and we will create your login and set everything up for you. It covers both the JB One app and the web catalogue.

Which printers does the app work with?

Thermal label and receipt printers over Bluetooth LE, USB (OTG) or Wi-Fi/LAN, using the TSPL (TSC and similar) or ESC/POS protocols. Check that your printer supports Bluetooth LE. The standard jewellery tag size is 81 mm by 12 mm, and you can add your own sizes.

Can different staff see different things?

Yes. Each person is given only the modules they need, so a billing assistant can see just the calculator and the live rate while a tagging assistant sees only label printing.

Where does the gold rate come from?

From a public gold and silver rate page, refreshed every 15 minutes, and kept on the device if the network drops.

Can customers buy online from the catalogue?

Enquiry on WhatsApp is switched on by default. Customer accounts, cart and online purchase are optional features that we can turn on for a shop.

Is our data private?

JB One shows no ads and uses no third-party analytics or trackers. The online catalogue's dashboard only counts product views and wishlist adds, without identifying visitors. Read the privacy policy.
