It really depends on the nature of your business and what tasks you wish to digitize.
Furthermore, depending on which part of the customers’ experience you want to prioritize, you might want to opt-out of automation for a few and automate the rest.
It’s not advisable to automate as much as you can (which is what most people do for efficiency), especially if you’re a small or medium-sized business. Hence, first and foremost, carefully determine what parts of your business:
a) can be automated
b) require automation
c) is not high enough in your list of priorities to be more hands-on on the task
Selecting the best tools that suit your business is step 2.
