My view is for a care home that full security on emails, business software needs to be massively secure and instant traceability with full instant back up of everything and this with 365 & google is automatically done, and the user can jump on any computer and they are in. I would not be comfortable with smaller web companies offering the trimmed down versions of office products, and in a world of online meetings - 365 will have full ‘teams’ in place which is massively used.
If the worker has to self isolate at home - 365 and google, they just log in and whole of there office is at home. Maybe this is the same with the other platforms offered, but I would be unsure.
This also needs to be future proof in my opinion. I would as @casey1823 has said offer them the top packages for 365 or google who are top if their game. As a great web designer as you are @flashman I would not want the burden of this over my head as you will end up being the one who will be acting as support all the time. That’s why I love Google’s business package - 1 click and support is either online or call then free.
I would offer them your website services, and then links to the top 2 and let them choose.
To be fair you did the best thing by showing them 365, that’s as standard as searching online with google!
Good kick though - sounds like a nice project.
