No the big question is have you tried it? it's smart to question but it's disingenuous to knock a product that could be helpful to a lot of people and a revenue booster for the dealer and then promote your own services . Most companies hosting Sage charge $50 per user per month, or more. TSPlus is a one time $490 and an annual maintenance of $83. NO CITRIX OR MICROSOFT REMOTE DESKTOP LICENSES NEEDED - just an internet connection. For an Owner or traveling salesperson who wants to check his Customers records, check inventory levels or even place a Sales Order in real time or run reports, this is a bargain. And you can log into any other program on the computer; you are not limited to just Sage.
Not too long ago, a number of dealers were looking for ways to make Sage 100 backward compatible with older servers. We all know that many of us installed Sage 100 on Customer's Windows 10 workstations long before Windows 10 was certified by Sage. And Thousands of Users, I would think, already use Remote Desktop to access their Sage 100 from home, remote office or hotel. Sage doesn't care. With TSPlus you can do the same thing from a device.
Try it or not, in two days on Black Friday there are going to be a lot of retail Customers placing orders and price lookups on iPads, Android and Surface tablets as they work the aisles trying to accommodate the mob.
