How to predict possible problems in the provision of technical support services?

Question

Business Informatics

Good afternoon. I work as a freelancer. Clients mainly come through word of mouth, or new tasks from old ones.
Not so long ago, an idea appeared - to provide technical support services on a subscription basis.
Transfer clients to your vds. Apart from hosting include several hours of work per month.
For me, the convenience is that everything is close, you don’t have to keep heaps of hosting accounts and swear with those support, and a more stable income.
Skills in web administration are available.
The clients themselves supported the idea and almost agreed on the price.

At the moment I'm trying to predict what pitfalls can expect me. So far, I only see a problem with domains, because. many clients have one service with hosting.
I ask the community to share their experience in supporting such projects or criticize the idea.

Answer 1

The biggest risk is that your wdska will fall.
And with it your clients, pain, blood, orgy will fall.
Keep production clients at their facilities, the problem with passwords/accounts is far-fetched.
Register your public key on the clients' machines and there are no problems.
Regarding domains - not a problem at all, change the A record and work on, even the mail will not fall off.
I do not advise hosting DNS - for the same reason that I described above.

Answer 2

It is useless to compete with the scale of hosting.
1. For your case, it is enough to transfer everything to one host. And contact his tech. support.
2. If you cannot predict possible problems, then you are not competent enough in this task. You can set prices offhand, just don't make these prices fixed forever, then adjust as experience comes.
3. Knowing how much hosting costs now since then. support - I strongly doubt that you can financially provide more favorable conditions for your customers. This can only be done profitably on a huge number of supported servers.
4. It's another matter if clients want to pay you many times more than those on the side. support- for example, for greater sensitivity and greater quality.

Answer 3

Typical problems of small hosts: mail flow problem, site hacks, DDoS, server crash on Friday at 23:59, software updates due to new vulnerabilities, keeping a reasonable amount of backups away from production. I would not contact - there will be no time left for the main activity. Just like hosters do not get involved in website development.
Take a fat tariff from some hoster and place it.
