It's a big toolbox, like SAP. Everything is a "feature"

We had the luxury of 10 years of ecommerce storefront and inventory management on a proprietary, non-extensible system that was developed by a very forward thinking team in the early 2000s. It lacked some wiz-bang features, but offered order mgmt, inventory management, image management, promotions, etc.

The back-end interfaces, while needing a couple of features, did everything we needed to run a 100K / mo autoparts biz with over 15,000 SKUs, and had excellent, intuitive interfaces out of the box.

Sadly that system was end-of-lifed in 2015, and we looked at a development outfit ASPDNFSF as a replacement.

In a word, the system is simply a box full of tools that you use to build >everything< in your customer facing and back-end user experience. The default layouts for inventory management, order management are horrible from a usability perspective. It will function, but is klunky and kludgy.

The good news is that because it's a relatively open architecture, you can build whatever you want.

The bad news is that every single usability improvement is a "feature".

We compared the major features of our old system to what ASPDNF could provide, and it looked like just what we wanted. Little did we know all of the little "built-ins" that we assumed any competent system would have put into place for navigating / moving around in order mgmt, inventory mgmt, just were not there.

The customer facing check-out pages are klunky and awkward out of the box, so plan on customizing those too.

We will nearly double our initial development cost estimates by the time we are done on custom development on basic usability mods.

In the end our old system cost about $1000/month, charges based on revenue.

We have at least 6 months and $35K into this creation of a comparable ASPDNFSF implementation, having the luxury of our old system as a model, and are still lacking back-end functionality we enjoyed in the old system.

Biggest technical issues baked into the system?
Apple / MacOS browser shopping cart compatibility problems
and real time shipping rate calculator that will not return
dimensional rates! (custom fixes required for both of those).

Be careful, and look at key usability on the back-end before committing.
