Zoho Assist has been the remote support tool I keep coming back to because it handles the normal messy stuff well: quick on-demand sessions, unattended machines, screen sharing, file transfer, and customers who are behind whatever firewall or browser setup they forgot to mention. I care less about flashy dashboards and more about whether a session starts when a store manager is waiting, and this has been steady for us. The Zoho ecosystem helps too, especially if your tickets and customer notes already live there. It is not magic, you still need sensible permissions and a clean list of unattended devices or it gets cluttered fast, but setup is simple enough and the value is strong compared with the heavier remote tools we looked at. For day-to-day support work, it just saves time, which is the point.
