POS for Bubble Tea (Trà Sữa) — Recipes, Toppings & Aggregators Under Control

What we hear from operators

• Sugar levels (30/50/70/100%) and topping combos vary between staff — cup cost swings 12–18% for the 'same' drink.
• GrabFood lists a drink as 'Trà Sữa Truyền Thống M', ShopeeFood as 'Milk Tea Classic M' — the POS treats them as two SKUs, inventory and reports both wrong.
• KOL campaigns run 'mua 2 tặng 1' bundles but the POS discounts the wrong item, eating margin on the wrong SKU.
• Peak-hour queues at 15:00 lose 1 in 4 walk-ins because staff can't see queue length across the delivery hatch.

Why LOOP fits this segment

• Recipe-level inventory deducts sugar, tea base and each topping in millilitres/grams per sugar level and cup size — daily variance under 1%.
• Aggregator name-normalisation maps GrabFood, ShopeeFood, Be and dine-in variants to the same recipe so inventory and demand forecast see one SKU.
• Campaign engine enforces which items a promo discounts — 'mua 2 tặng 1' always discounts the cheapest cup, never a topping-heavy one.
• Peak-hour queue dashboard shows dine-in + delivery ticket count in real time, with AI staffing recommendation for the next 60 minutes.

What you get

• Sub-3-second order entry with sugar/ice/topping modifier shortcuts.
• Native HĐĐT (Vietnamese e-invoice) on every receipt, including delivery.
• Zalo Mini App loyalty with stamp + points hybrid.
• Batch prep list generated from AI demand forecast the night before (tea base, syrups, pearl batches).
• Multi-outlet central-recipe control so every branch's Matcha Latte uses the same 12g matcha and 220ml milk.

Frequently asked

Does LOOP handle Vietnamese sugar-level modifiers (30/50/70/100%)?

Yes, natively. Each sugar level maps to a different syrup weight in the recipe, and inventory deducts accordingly. Reports break down by sugar level so you can spot preference drift.

Can LOOP consolidate GrabFood + ShopeeFood + Be into one queue?

Yes. All three aggregators feed a single kitchen queue with name-normalisation, so 'Milk Tea Classic M' and 'Trà Sữa Truyền Thống M' deduct from the same recipe and appear as one SKU in reports.

How does LOOP handle 'mua 2 tặng 1' promo bundles?

The promo engine automatically discounts the cheapest eligible cup, never a topping-heavy one, so margin stays predictable. Promos can be scoped to specific hours, SKUs, or KOL codes.

Does the Zalo loyalty stamp system work for bubble tea?

Yes. Stamps unlock bonus toppings; points redeem for a full cup.

What hardware do bubble tea shops typically need?

One Android tablet for the till, one 80mm thermal printer for receipts, and a second printer at the prep station for delivery labels. Optional: a queue-status monitor visible from the counter.
