Selling at a flea market, convention, or pop-up is fast, loud, and unpredictable. A little setup before the weekend makes it much easier to keep your inventory accurate across the table and your online store — and to spend your energy on customers instead of spreadsheets.
Before the show
Pick what’s going to the table and check current market prices
Keep a count of every box you pack
Charge your phone or tablet and bring a backup battery
Decide your trade rates ahead of time in case buyers bring items
At the table
Ring up sales and trades on your phone or tablet. Take cash, card, or store credit, and let regulars earn rewards just like they would in a store.
When the Wi-Fi drops
Event Wi-Fi is famously unreliable. GameSnapPOS is cloud-based, but if your connection drops briefly you can keep recording transactions — they sync automatically once you’re back online. Keep a mobile hotspot handy for longer outages.
After the show
What sold comes off your online listings, and what didn’t is already counted for next weekend. Take a few minutes to review the day:
Which categories sold best
What you took in on trades
Which items you should bring more — or less — of next time
