I’m represented by an agency that handles marketing, customer vetting, legal/contract, billing and payments, etc. I communicate with my customers by email or phone call unless they have a system they ask me to use (Slack, Jira et al). Most of my customers have told me the last freelancer/shop they worked with stopped communicating, or took days to answer emails, or tried to force them to use some ticketing system. So I always answer calls and emails right away. No big secret, just show some respect for the customer.
