Amp Back in Stock | PreOrder

This app is top notch not only for the functionality / price spectrum, ease of use to get up and running, but also because of amazing customer support.
Matt & Jack go beyond expectations and truly are helpful if a problem is to arise. We pay other software companies exponentially more money and they seem to just gloss over our issues.
Our company has a unique business model where things go in/out of stock regularly and Matt was nice enough to explain what was going on and come up with a solution to a rather complex problem.
Can't recommend enough.
