I manage the Google Maps listings for two local Amish businesses, as well as send the occasional e-mail for them when a supplier or other business reason requires they use e-mail.

They offered to pay me for my time, but I refused as I'm happy to help my neighbors. They seemed pretty uncomfortable with me helping without anything in return, so they pay me back in discounted products or labor of their own.

I am not sure what is forbidden. There was a YT video about computer they were using for business. It was stripped down OS (windows xp?) that only had office apps, or something like that.

I am unable to find the video, but here is an interesting story: https://www.npr.org/sections/money/2013/02/25/172886170/a-co...

I'm not sure about "forbidden" per se but they definitely make accommodations for various things, e.g. riding as passengers in cars for long trips.

I'm not sure if payment is involved, but I've heard Orthodox Jews can and do seek non-Jewish help when they need e.g. light switches toggled on the Sabbath.

Yes. They pay folks to drive them around.
