MioMio went from a standing start in 2024 to opening ten new stores in the first half of 2026 alone. That pace is not a property of the store design — it is a property of everything behind it. A new MioMio franchisee receives a working, tax-compliant retail system on day one, not a laptop and a spreadsheet. Every MioMio store runs on Lemeng.
Figures marked as growth and store-economics data are as publicly reported by MioMio in its own 2026 half-year review (published 30 July 2026) and on its franchise page.
A company-operated chain grows by adding stores the head office controls. A franchise network grows by handing a store to someone who has never run one — and trusting that the economics still work on the other side. MioMio's franchise page states the promise plainly: VND 800 million to start, payback from 12 months, gross margin of 28–30%, and a store of at least 100 m² carrying more than 3,000 SKUs.
That promise creates four operational problems that a POS system either solves or makes worse.
MioMio's own training support covers operations, merchandising and store management, and the company describes transferring "standardised procedures that are easy to apply and replicate." That is a reasonable thing to promise — but procedure documents do not hold a store together at 7pm on a Saturday. If the cashier screen, the returns flow and the stock count all work differently in each store, the standardised procedure exists only on paper.
MioMio publishes a seven-step, 30-day path from first conversation to opening day: consultation, intent confirmation and deposit, site assessment and contract, handover and design, construction and fixture installation, recruitment, training and first stock order, then merchandising and opening.
Notice what is missing from that list: any slack. In a 30-day schedule, a two-week IT setup phase is not a minor delay — it is a third of the entire project. For the model to hold, the retail platform has to arrive already configured: product files loaded, prices set, tax rules applied, payment methods live.
MioMio's own reported store economics put average monthly revenue at roughly VND 500 million per store — several times the VND 1 billion annual threshold. In practice this means every MioMio store, franchised or not, has to issue tax-authority-connected invoices from the point of sale. A store that cannot do this is not a slow store; it is an exposed one.
The tension in every franchise network is the same. The franchisee wants autonomy over their own business. Head office wants consistency, brand control and a consolidated view. Resolve it with monthly spreadsheets and you get numbers that arrive three weeks late, in four different formats, with no way to catch a pricing error or a stock-out until it has already cost a month of sales.
MioMio runs its network on Lemeng. The design principle is that the same system has to feel simple at the counter and complete at head office — because those are two different users looking at the same data.
MioMio stores open with a retail point-of-sale screen built for high-volume, low-value transactions — the pattern that defines snack retail, where a customer may leave with eight items in one basket. Barcode scanning, category browsing and fast tender keep the queue moving at the roughly 300 customer visits a day that MioMio reports per store. New staff follow the same on-screen flow in every store, which is what makes MioMio's standardised training genuinely transferable rather than aspirational.
Snack retail lives and dies on shelf productivity. With more than 3,000 SKUs in a space that size, the questions that decide margin are narrow: which lines turn, which sit, which are about to expire, and what needs replenishing before the weekend. Lemeng inventory management keeps a single item master across the network, supports batch and expiry tracking, and turns the daily stock routine into a scan rather than a count. Because the item master is shared, a product set up once at head office is ready in every store — including the one opening next month.
Vietnamese shoppers pay the way they pay. Lemeng payments handles cash, card and QR-based transfer at the counter, and issues the e-invoice required by Decree 70/2025/ND-CP directly from the terminal, with data transmitted to the tax authority. This is the piece that international POS platforms consistently cannot deliver in Vietnam — and the piece that decides whether a franchise store is compliant on its first day of trading.
A snack purchase is habitual, and habits are worth capturing. Lemeng membership means a customer who joins at one MioMio store is recognised at any other — points, promotions and purchase history travel with them. In a franchise network this matters disproportionately: it converts a collection of independently owned shops into something that actually behaves like one brand from the customer's point of view.
This is the part that makes the model scale. Lemeng chain-store management separates head-office permissions from store-level permissions. A franchisee sees their own sales, stock, staff and shift data — and nothing belonging to anyone else. Head office sees the consolidated picture across every store, with the ability to push pricing, promotions and product files out to the whole network at once, and to spot a store that has gone quiet.
MioMio's published opening process is seven steps over 30 days. What follows is how the retail platform maps onto it — which is the practical answer to why a store can open in a month without a separate IT project.
| MioMio's opening step | What happens in the platform |
|---|---|
| 01 — Franchise consultation | Franchisee is shown the live system, not a brochure: this is the screen your staff will use. |
| 02 — Intent confirmation and deposit | Store account provisioned; head-office template assigned. |
| 03 — Site assessment and contract | Store profile created with location, format and approval rights. |
| 04 — Handover and store design | Catalogue, pricing and tax rules inherited from the network template — no data entry from zero. |
| 05 — Construction and fixtures | Hardware specified and pre-configured; terminals registered to the store account. |
| 06 — Recruitment, training and first stock order | Staff accounts created with role permissions; opening stock received against the shared item master. |
| 07 — Merchandising and opening | Store goes live. Day-one sales, payments and e-invoices flow to head office immediately. |
MioMio reported ten new stores opened in the first half of 2026, across Ho Chi Minh City, Binh Duong, Dong Nai and Binh Phuoc, and received more than 1,000 franchise enquiries in the same period at a conversion rate of 8–10%. Average monthly revenue per store is reported at approximately VND 500 million, with roughly 300 customer visits per day per store.
MioMio's expansion has so far moved through southern Vietnam. Every additional province adds a new set of operational questions — a new tax office relationship, a new payment mix, a new set of local suppliers — and the value of a standardised platform is that none of those questions require a new system.
For a franchise model at this stage, the next frontier is usually the same: giving prospective franchisees a way to evaluate the business in a language they read. MioMio already publishes a Chinese-language version of its site. An English-language edition of its franchise material would open the same conversation with a different pool of investors.
MioMio uses Lemeng as its retail POS platform across its franchise network in Vietnam. Lemeng covers point of sale, inventory management, payments and e-invoicing, membership, and multi-store management from head office.
MioMio opened 10 new stores in the first half of 2026 and operates across Ho Chi Minh City, Binh Duong, Dong Nai and Binh Phuoc. The brand was founded in 2024, carries more than 3,000 SKUs, and runs a store format of 100 m² and above.
Yes. Decree 70/2025/ND-CP requires household businesses and individual traders with annual revenue of VND 1 billion or more to issue e-invoices generated from cash registers connected to the tax authority. MioMio issues these invoices at the point of sale through Lemeng, with transaction data transmitted as required.
Yes — and it has to, or head office is flying blind. Lemeng separates head-office permissions from store-level permissions: a franchisee sees only their own store's sales, stock, staff and compliance status, while head office keeps a consolidated view of the entire network and can push pricing, promotions and product data out to every store at once.
