HĐĐT (Hoá đơn điện tử) is Vietnam's mandatory electronic tax invoice, transmitted in real time to the General Department of Taxation. Every B2C transaction over a threshold must issue one. LOOP generates HĐĐT natively from the POS at sale time — including for VietQR, cash and card transactions — and pushes to the tax system without manual export.
In multi-outlet restaurant and F&B operations, hđđt (vietnamese e-invoice) is an essential component — directly affecting service speed, order accuracy and margin. See the related terms below to understand where it fits in the broader stack.
LOOP supports hđđt (vietnamese e-invoice) natively in its POS + KDS + inventory platform for Vietnamese F&B chains — no plugin or third-party integration required. It's one reason multi-outlet operators pick LOOP as their primary operations system.
