Unless you want to use every aspect of DDI for your company, I would not recommend their program. We have been unable to integrate their system with outside systems and even our website without having to pay for a "work around". If you do consider using other aspects of their offerings, make sure to get a trial of things like their CRM capabilities, as I have found them to be quite outdated in comparison to other programs
This ERP is suited for products that do not require customizations or personalization. Ideally, if you are selling a product as is, then S2K will fit your needs. Make sure to have all of the requirements for each piece laid out. For instance, with products - know all of your attributes and functionality for product pages ahead of time. Include this in the presentation for ERP selection. Ask what functionality is out of the box, and what is a customization. Ask for quotes ahead of time. This may increase the overall cost of the ERP as well as the time it takes to launch. Example: Product reviews, cross sells, remarketing, abandoned cart integration, etc
If this is someone's first ERP implementation, I strongly suggest you ask for services to help implement. Ask for training on every aspect of the implementation. Make sure this is put into the overall ERP quote
