One thing that many miss is that using "processes" takes potential personality clash out of the equation.

Both on Linked-In and at a recent customer I was asked if they should employ a Sales Manager at a small MSP?

I have shared my response below.

I was recently asked input on what information an MSP should supply to their customer.  At one level it depends on just how technical the customer is; but either way, I don't believe that you should routinely overload the customer with too much information.  In the end they either ignore the volumes of data or ask questions about things they don' t really understand.  Today's PSA and RMM solutions are capable of producing volumes of information but still lack a good clear "Executive Summary" - they try, but not quite there.
Your job as a MSP is to make sure you adhere to the word "Managed" - so you had better manage.  Yes, this can be a little extra work on the surface, but I suggest by doing this you will not only save more time but have a happier customer.  This information will in the main be extracted from your PSA & RMM systems but you can then add some value around this. I have shown a screen shot of a basic report.

Of course, you can either provide or make available on request the fully detailed information; but this way you are being a better IT Manager for your client.
