What we like best about JET Commerce was that it's very easy to use with all of our products being in separate divisions within one system so there are no cross-divisional issues or problems when integrating data between them into their systems! The only thing I disliked at this time were some minor UI/UX changes which would be easily fixed if they made updates available via an update program rather than having us upgrade every year (this has been remedied by now).
We've had great success using jetcommerce as both sales channel management software but also have used its order fulfillment capabilities too - just recently started working through these features more fully ourselves though still early days yet!! So far everything looks good from what i can see visually however will continue monitoring closely over next few months until final rollout across whole business before making any conclusions regarding performance etc.
