Self-Service Car Wash - Remote $$$ collection

[Kevin Kohler]

I am buying 2 self-service Car washes as a JV and my partner and I are looking at best practices for how to remotely operate the properties. There is a guy already that removes trash and moves coins around from machines etc, but the seller lives locally when it comes to taking the cash to the bank for deposits. What are the things we should be looking at to facilitate efficient and safe collection of the revenue and depositing it into the bank?

Also, what are some good resources to compare newer tech for potential equipment upgrades etc to get the equipment onsite converted more to cashless payment systems?  

Thanks in advance for any insights!
