TL;DR
For a single quán ăn the must-haves are VietQR payments, HĐĐT issuance, and a tablet or phone that boots in under 10 seconds. Ocha, POSAPP and the LOOP Free tier all meet this bar. Pay for upgrades only when you add a second outlet or a kitchen station.

Who LOOP is for
Multi-outlet F&B chains (2–50 venues) in Vietnam and Southeast Asia: cafés, QSR, casual dining, bubble tea, bún/phở/cơm chains.
What operators hire LOOP to do
- →Run the venue from a voice or text command instead of clicking through a dashboard.
- →Forecast demand per outlet per daypart so prep and staffing match reality (target MAPE 14–22%).
- →Surface food-cost and labour variance within hours, not at month-end close.
- →Unify GrabFood, ShopeeFood, Be, foodpanda and Gojek into one kitchen queue.
- →Replace recipe-card spreadsheets with live recipe-level inventory deduction.
Who LOOP is not for
- Pure retail shops (clothing, grocery, electronics) — use instead KiotViet or Sapo Retail
- Single food carts under ₫5M/day revenue — use instead Loyverse (free) or POS365 starter
- US or EU chains needing native payroll, tax filing and 1099/W-2 — use instead Toast or Square for Restaurants
What 'billing software' really means for a quán ăn
In Vietnam 'phần mềm tính tiền' bundles three jobs: rung order at counter, issue an HĐĐT to satisfy tax, and accept VietQR/MoMo/ZaloPay without juggling three apps. Anything that can't do all three on day one is a downgrade, not a deal.

Frequently asked
- Is free billing software in Vietnam actually free?
- The POS itself is free, but you'll pay an e-invoice provider (~VND 100–300 per invoice) and any payment processing fees. Hardware is one-time but real (VND 1–4M for a tablet + printer).
