Monthly retainer billing should run on autopilot. Taskade Genesis generates retainer invoices that clearly show hours consumed, remaining balance, and any rollover terms — then sends them on schedule without you touching a thing.
What Is an AI Retainer Invoice Generator?
A Taskade Genesis app that manages recurring retainer billing. It tracks monthly hours against the retainer cap, calculates overage charges, and auto-generates a formatted invoice at the start of each cycle — all from your initial setup prompt.
