Collection Velocity Stack

Collection Velocity Stack treats invoicing as a three-layer system where each layer sets the ceiling for the next: how fast work becomes a billable artifact, how fast that artifact becomes a payable invoice, and how fast the invoice becomes cleared cash. Agencies usually optimize only the middle layer (chasing overdue invoices) while the real drag sits upstream, where tracked hours sit unconverted for a week or more. Harvest shortens layer one by turning timers and expenses directly into draft invoices, while Agicap attacks layer three by connecting bank and accounting data to forecast liquidity up to 13 weeks out. The stack matters because a retainer client who pays in 45 days instead of 15 forces the agency to fund delivery from reserves. Fix the slowest layer first; speeding up reminders on invoices that were never issued on time changes nothing.
