Marcos Dayan
@marcosdayan
O2C billing and collections leader driving SOX-compliant cash forecasting and automation.
What I'm looking for
I’m a Finance and Order-to-Cash professional with 7+ years in billing, collections, and accounts receivable management. I currently lead the global O2C process, ensuring SOX compliance while improving day-to-day execution across billing, collections, and accounts receivable.
I built an Accounts Receivable Forecast model from scratch—projecting monthly, quarterly, and annual AR performance—and it’s now the standard reference used by FP&A and senior management for cash-flow planning and revenue projections. I also drive automation initiatives using Excel and VBA to streamline invoice generation, aging reports, and data reconciliation, reducing manual effort and processing errors; I’m recognized with the company-wide Bailey Award (2024) for “Act with Urgency.”
