Sorry I didn't see this one yesterday. I didn't get home from work until 10pm, and missed it.
Fiber NEVER goes down here, but electric can sometimes fail.
I wouldn't let that concern stand in your way from considering one of the cloud based products. Just about every smartphone has a (WIFI) MOBILE HOTSPOT button that you can turn on, in such an instance of a brief power failure or internet failure. This will turn your phone into an internet provider, that you can then access from your tablet or desktop, until either of those items come back on. (as long as the tablet is charged, or the desktop is on a battery backup)
Cloud is the future and where most popular apps are heading. (Microsoft, Adobe, Quicken/Intuit, Netflix, etc) It uses encryption, and you don't have to have a dedicated server or backups locally in your shop. If your computer dies, it isn't the nightmare it used to be. (You can just move to another device, log in, and be up again) The folks that run the server do your daily price updates and software updates.
We switched from Lifesaver Desktop to Lifesaver Cloud on January 1st of this year, and it has been fantastic so far. It came in very handy while we were closed multiple months due to Covid, to work from home. Since our phone system is also cloud based, we were able to take calls and give basic quotes from home -- just like we were here in the shop.
As I always suggest, kick the tires and give the major products a test drive to see which one works well, make sure they provide weekly price updates for all of your vendors, and try out their technical support with a question or two. This will give you the confidence to make the right decision.
That's my take, in any case. Good luck with the research and congratulations for making the decision to employ the many benefits of a pro point of sale system!
