STOQ is very simple to use, yet quite powerful in function. We had a couple minor display adjustments that we needed fixed and Arnab helped me out and had the adjustments in place within just a few minutes. Very happy with my decision to use STOQ for Pre-Orders and Back In Stock notifications.

— Sheppy Cards

Just what we needed. A simple re-stock notification app. We only have their free plan active and only utilise the re-stock option - and that works just fine for us. There are far more options available if you're wanting them like the pre-sale options, etc. But I liked how you can pick and choose just what you need for your business from this app and make it work for you. There has only been one...

— MOD

STOQ is a must-have app. The revenue it generates is significant and after we had a bit of trouble with our new theme messing about we contacted their devs and they fixed the problem immediately.

Fantastic app backed by incredible tech support If you are looking for a reliable preorder and restock alert app, look no further than STOQ. Not only is the software highly effective, but their tech support is brilliant. They are fast, knowledgeable, and always available—they even resolved an issue for me on a Saturday without missing a beat. 5 stars all the way!

Does what it needs to and the customer support is fantastic

— Mon Cinq

The app can offer pre-orders in multi-markets. Notifyme also works well. Integration via Klaviyo is slightly a challenge and you can only customize the Klaviyo emails using HTML. But overall, good app for our needs. Customer support is also knowledgeable and able to fulfill our help requests.
