Online Store & QR Menu · Free as your first app
Your own store. Your customers. No marketplace in between.
Publish a store for each branch in your name and colours, and use the same store as your QR menu. Orders arrive with real invoices, and stock is reserved the moment a customer checks out.
What you get
Your own store. Your customers. No marketplace in between.
Your look, your words
Pick one of three themes, set your accent colour, and write your own headline and announcement.
Draft, review, publish
Changes stay in draft until you review and publish them.
One store, two doors
The same store opens as a QR menu at its own link — one catalogue, one set of prices.
A real invoice for every order
Prices are checked by the system itself, and every order issues a real invoice.
Pay by link or order on WhatsApp
Customers pay through the payment account you connect, or send their order to you on WhatsApp.
A clear order queue
Received, accepted, preparing, ready, dispatched, completed — stock is reserved at checkout and taken at handover.

Good questions.
Is STAK a marketplace?
No. STAK is software for your business. The store is yours, and so are your customers.
Can I use it as a table menu?
Yes. The same store opens as a QR menu at its own link, with the same items and prices.
Your whole business. One stack.
