The last item sold twice
Two customers want it at the same time, and you have to apologise to one of them.

Sound familiar?
Selling is easy. Keeping track of it all, much less so.
An order lost in the messages
Between messages, calls and notes, an order slips through the cracks.
A stock count that means nothing
The notebook says 5, the shelf says 2. Nobody knows what happened.
Stackwello solves all three.
Everything you need, nothing you don’t
Three simple tools that work together
Products
A clear catalogue, even with sizes and colours
Each product has its photos, its description and its variants, “Red / M”, “Blue / L”… each with its own price, compare-at price and reference.
- Up to 3 options per product
- Draft, active or archived
- Fast search, even without accents
Stock
Accurate stock, and you always know why
Stock never changes silently: every movement is kept with its reason, its date and who made it. It never goes below zero.
- Arrival, sale, return, loss, stocktake
- Alert when an item is almost sold out
- The last item can only be sold once
Orders
Every order followed, from “To handle” to “Delivered”
Prices come from your catalogue and the total is calculated for you. Stock goes down with the order and comes back if it is cancelled.
- To handle → Confirmed → Shipped → Delivered
- Paid or not, at a glance
- Your order numbers, your way
