About
Your shop fits in your pocket.
An order comes in: your phone rings, even in your pocket. You see the customer, the amount, what they bought. You pack the parcel, print the label, and the customer gets their tracking. Without opening a computer.
Opustack is the app for ambitious brands running their online shop on Opustack.
YOUR DAY AT A GLANCE
Today's revenue, order count and average basket, compared with yesterday at the same time. Orders waiting to be packed, oldest first.
NEVER MISS AN ORDER
A notification for every new order, even when the app is closed, with the sound of your choice: coins, a bell, a chime or a till. Pick the one that carries in your space.
THE WHOLE ORDER ON ONE SCREEN
The customer, their items, payment and delivery. Emailing them or opening directions takes one tap.
SHIP FROM YOUR PHONE
Pick the items of a parcel, create the label, print it with AirPrint or share it. Confirm the parcel has left, with or without an email to the customer. Partial shipments are supported: the rest leaves when it arrives.
YOUR CATALOGUE AT HAND
Add a product with photos from the camera or your library. Change a price or a stock level in seconds. See at a glance what is still a draft or out of stock.
THE NUMBERS THAT MATTER
Sales over 7, 30 or 90 days, or any dates you choose, compared with the previous period. Visits, top pages and traffic sources, to know what brings your customers in.
BUILT FOR THE FLOOR
Dark mode, French and English, instant loading of what you have already opened, even on 3G. Your screens open on what is already there, then update.
WHAT YOU NEED
An Opustack account. You sign in with your email address and a code sent to it, then your password, which goes straight to your shop. No list of shops is ever shown: you only see your own.
We never sell data and use no advertising trackers. Notifications only contain your shop name, the order number and its amount.
Opustack is managed e-commerce infrastructure: we build, host and run your online shop. This app is its daily cockpit.
