No card readers required, no account registration needed—just open the app on your phone and start using it. ------ Key Features ------ 【Visual Product Wall Checkout】 A photo-centric checkout interface that lets you find products at a glance, tap to add to cart, and complete transactions quickly. Layout density and image display can be adjusted to fit your on-site needs. 【Product Variations】 Create multiple variations per product (color, size, style…), each with its own price and stock. Pick a variation at checkout, and break down sales by variation. 【Bonus / Gift Display】 Mark items with "With Bonus" in the product settings. The bonus will be displayed directly in the item list during checkout, making it clear what the customer should receive so you never miss a giveaway. 【Discount Settings】 Supports spend-threshold gift reminders. Alerts automatically pop up when the total reaches the target, so you don't have to keep track of every promotion yourself—the system remembers it all. 【Change Assist】 Automatically calculates change during cash transactions. Stay focused on welcoming customers without needing mental math or worrying about giving the wrong change. 【Inventory Management】 See remaining stock levels at a glance with automatic low-stock alerts. No more guessing when to restock or remove an item on-site. 【Pre-order Registration】 Supports importing pre-order lists to verify pickup status on-site. Prevents missed orders and duplicate distributions. 【Display Settings】 Choose to gray out, move to back, or hide sold-out products. Customize stock numbers to show only low-stock alerts or all quantities, keeping your booth interface at your preferred pace. ------ Who It’s For ------ • Market, cultural, and craft stalls • Pop-up stores and limited-time events • Small sellers who don't want to carry a bulky cash register • Personal brands needing quick on-site product management ------ Design Philosophy ------ BOO-POS isn't designed for chain stores. It's built for those who run a stall alone, managing customers and handling payments simultaneously. Lightweight, fast, and highly intuitive.
