Princess Nugget Shop review for NASP Connected Inventory

At first I was so excited about having found this app. It seemed to respond to my needs. But when things got real, the app completely failed me. I do flash sales which attract many buyers and thus many sales in a short time. I sell sheets from rolls so I have bundles for this as instructed by Connected Inventory. Followed their set-up instructions to the letter. And when I needed it, It sold a whole lot of stock that I didn't have. Their reply after my complaint: We noticed you had a lot of sales in a short period of time. This app is not suited for this. People need to be warned for this. I have a bunch of disappointed customers and a business i'm trying to build up. I lost clients due to this app. Be wary!!!!!!
