System of Accounting of Customer Registrations

Today completed the setting of the customer registration accounting system for the customer - implemented on Google tables.

What distinguishes me from other experts and professionals - I apply a creative approach and systemic thinking. I count future possible scenarios and customize business processes with these factors, as well as systematize all data flows for automation.
The main rule is less manual operations, one data should not be entered into the system several times in different places: only once, and then interconnections and algorithms are already working.
