Frequently asked questions
How much revenue do stockouts actually cost retailers?+
Industry research estimates stockouts cost retailers around 4% of annual revenue on average. For size-based products at popups, the impact is often higher.
How is this different from a 'notify me when back in stock' email?+
Back-in-stock emails capture interest after the customer leaves. Loost captures the sale while they are still in front of your product.
Does the customer need to download an app?+
No. Customers scan the QR code with their phone camera and complete checkout instantly — no app required.
What happens if the warehouse runs out too?+
Inventory sync ensures customers can only order available warehouse stock. If it's sold out everywhere, it won't appear.
Do I need to change my POS system?+
No. Loost works alongside your existing POS and only handles out-of-stock recovery orders.
