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 — proven 34% repeat-visit lift vs 19% industry baseline (PEKO 2026).
• 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 — the PEKO 2026 dataset shows bubble tea chains hit 34% repeat-visit rate within 30 days (vs 19% industry baseline). 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.
