We have been running Connected Business for 10 years now (formally Interprise). We ran on V13 for quite a few years getting by, without making it work perfectly for us. We then decided to upgrade to V16, and then make some small customisations to really make this a smooth system. easier said than done!
$18K later, we didnt achieve much at all. The serious lack of standard built in reports is pathetic. anything from analysing sales by state, or by product group is all customisable. average of $1K per report...
Also, the interface hasnt improved at all from previous versions. only in an index/ text view - no graphs etc.
We ended up moving to Odoo. Same price - far better cloud based platform.
