“A coffee with a slice of cake—settled in one checkout.”

Coffee stores sell drinks by day and add light-food desserts in the afternoon; broad categories make separate checkout troublesome for both customers and staff.

The system unifies coffee, bakery and retail into one order, with cross-category points and coupons; mini-program self-order eases peaks.

After one-stop checkout, attach sales are easier and afternoon tea AOV clearly rises.
