Philipp Albrecht is the founder of Cash Flow Calendar. He spent years as a freelancer and built the app after missing a rent payment while waiting on client invoices — not because he didn't have the money, but because it hadn't landed yet. Everything on this blog comes from that problem: knowing what's coming in, what's going out, and on which day.
