All say they integrate into multiple external suppliers, hold inventory, multi-channel etc…. and have good diagrams on their websites to highlight this.
I know though that underneath the covers they don’t, all are slightly different with functionality moulded over the years by their customers.
There is one common trait through them all though, and that is that the architecture structure of every system looks the same (well similar).
The common parts of the architecture consist of the following 3 layers…..
- Selling System Layer
- Business Rules Layer
- Aggregation Layer
All call their layers something different, but they all do the same thing as described above, so don’t get too confused when looking at the various products diagrams and say they haven’t got an “Business Rules Layer”
It is encouraging in some way that all the major providers are doing something similar and I would say technically logical.
The key thing though as I mentioned above, is that under the bonnet, deep in the engine functionality they definitely don’t all do the same thing, and so when looking for a technology product/partner you need to make sure you do lift the bonnet and do a full MOT.
