I have been using this app for restock notifications for some time now. I am very grateful for the prompt and courteous assistance provided by the representative whenever any issues arose.

Excellent service and highly recommend. Leslie did a tremendous job providing personalized support and documentation regarding a new feature that’s being released so that we can be ahead of the curve. Very grateful and really appreciate the service continually being updated and approved. Keep up the good work!

Great app! We've used them for years.
— PEAX Equipment
Great customer service! Very helpful and the app is great. I love how you can keep up with customers and refer them to different comparable products if the item they are waiting for isn't coming back. Also love using this app to see where demand is and what we should invest and continue producing.

App glitches when customers trying to sign up for a notification. Requested a refund for one months subscription. No follow up after 35 days.

stop charging me I'm no longer using this app i send a email thank you if you can fix that that would be great!

Whatever you do, don't even think about downloading this app. You can't manage anything on your own; you need a customer representative for everything, but there aren't even any to contact. I send emails, and they only respond after three days. It's truly awful. Please don't waste your time using this app.
— REVEA
I've been using Back in Stock for 7 years and it's been a real money maker AND time saver for me. The tech support is very responsive.

Back in Stock is invaluable to our business. It gives our customers priority when we restock inventory and delivers alerts into their inbox immediately. Ultimately this yields more conversion for us. We love this app!
