For markets and fairs

Fill the booths. Check the papers. Open the gate.

Markets and fairs live on vendors: signing them up, placing them, checking their permits, and getting them through the gate on the morning. Karsenics handles that loop, and the books behind it.

Built for the organizers behind farmers markets, holiday markets, craft fairs, county and community fairs, night markets, and the vendor markets that run alongside a Pride or heritage festival.

The season as it actually goes

The vendor list is never quite right.

A market runs on the same list of vendors, over and over, and the list drifts every week. A booth gets double-booked. A license expired last month. A new vendor paid but never got a space. Karsenics keeps the list, the map, and the money in the same record.

  • Vendors apply by email, pay by check, and get a booth number by text
  • Business licenses and health permits are collected once and never checked again
  • The map is a drawing on someone's laptop, and it is wrong by the second week
  • Gate staff work from a printed list with a pen
  • The treasurer reconciles booth fees against the bank statement by hand
From the product

The gate, on the morning.

Check-in runs on a phone at the vendor gate. Every vendor shows with a booth number, the equipment they are due, and a flag if payment or a document is still outstanding, so the conversation happens at the gate and not at the booth.

The Check-In screen on the Vendor Gate station, 0 of 80 arrived, listing vendors with booth numbers, equipment delivered counts for tents and table sets, flags for payment outstanding and documents missing, and a Check in button on each
