How to Set Up Payments and Apps for Your Booth
Accept cash, cards, and peer-to-peer apps the right way, with a card reader setup, signage, and a clean record of every sale.
Published April 2, 2026
Every payment method you do not accept is a sale you might lose. Modern shoppers carry less cash than ever, so a vendor who only takes bills leaves money on the table. Here is how to set up payments that capture every buyer while keeping your records clean.
Offer three ways to pay
Cover the full range of how people carry money so no shopper walks away over a payment hurdle.
- Cash, with a small float of bills and coins for quick change.
- A tap-to-pay card reader for cards and digital wallets.
- At least one peer-to-peer payment app for cashless buyers.
Set up your card reader the right way
Pick a reader with low per-transaction fees and same-day or next-day deposits so your cash flow stays healthy. Charge it the night before, pair it to a charged phone, and pack a power bank because a dead device means a dead checkout. Post a small sign listing the payment apps and cards you accept so shoppers know before they ask.
Keep clean records for taxes
Whatever methods you accept, log every sale so your bookkeeping and sales tax are accurate. Most card readers and payment apps export a tidy report, and matching that against your cash count at the end of the day gives you a true picture of each event. Clean records make tax time painless and reveal which items and price tiers actually drive your revenue.
Make paying you effortless, and you remove the last barrier between a browser and a sale.
