About Easy Stock Buffer

Set a minimum stock level for each product variant at each location, or apply rules by collection. When online stock drops to that number, the add-to-cart button is blocked so the last units stay reserved for in-store customers, wholesale orders, or as a buffer against inventory sync delays. Get email alerts before you run out, either instantly or as a daily, weekly, or monthly report. The customer-facing message is fully editable. 5-minute setup, no code, no theme edits.

We were looking for a way to identify sold out items in our store and reached out to see what options were possible. Gustav was quick to respond and even customized a solution to our need. He tested and pushed the update overnight! We appreciate Gustav's willingness to go the extra mile!

his app worked perfectly for what we needed, and when I had an idea for an additional feature, Gustav went above and beyond by building it for us. Outstanding customer service and a fantastic app. Stop researching and install this app, you won't regret it!
