In this episode, Peter Kang and Sei-Wook Kim tackle one of the most critical yet misunderstood aspects of running an agency: cash flow management. They break down the dangerous gap between your P&L's accrual-based profitability and the real money in your bank account, explaining why even "profitable" agencies can face insolvency.
Peter and Sei-Wook share hard-earned lessons from their own journey, including how much cash reserve is ideal, when to use a line of credit, and the emotional calculus of using reserves to protect your team during a downturn.
