Stock Sorted

This was the simplest method I found to publish a product with multiple addon options while maintaining stock levels for everything. The developer was very helpful when I was setting up my store originally and recently responded very promptly (minutes) to a problem that showed up.

We process several thousand orders per hour during our high-volume product launches. Since this was our first time using Stock Sorted, we initially ran into a technical issue during a major traffic spike. However, Josef worked around the clock to address the problem immediately and fully resolved it. By our second launch, the system performed flawlessly with zero inventory discrepancies, allowing us to manage our drop with complete peace of mind. The developer's support is outstanding. Despite the time zone difference with Japan, he was always quick to respond and adjusted his availability to match our active business hours and live launch schedules. If your store struggles with managing shared stock for complex variants, this is hands-down the best app available. Highly recommended!
