When you start a new payment, you can charge a custom amount or sell products from your catalogue. Most Pebl Pay businesses enter an amount, so that's where the app starts — but it remembers whichever tab you used last.
Charge a custom amount (the usual way)
Tap New payment — you'll land on the Amount tab.
Type the amount and tap Confirm amount.
Sell products
Tap New payment and switch to the Products tab.
Search or browse your products and tap to add them. Use the + to change quantity.
Tap Checkout to review the cart, then Create payment.
Your catalogue is managed in the Dashboard — see Getting started with products. If a product's missing, add it there and it'll appear in the app.
Then choose how the customer wants to pay.
