A professional service provider is losing productivity and mental focus due to a single client's frequent ad-hoc requests, and has no way to bill for the true cost of workflow disruption and after-hours coordination.

Hourly billing captures only direct task time, not the mental, workflow, or schedule disruption costs from unscheduled, urgent, and fragmented ad-hoc client communication. There is no tool to automatically quantify and invoice the true cost of interruptions and priority handling.

InterruptBill

InterruptBill is a smart billing platform designed for service professionals who deal with constant client interruptions. It automatically detects ad-hoc requests outside of scheduled work blocks, logs the context-switching time and urgency level, and adds a dynamic disruption surcharge to invoices. This makes the true cost of last-minute, unscheduled work transparent to clients, discouraging unnecessary interruptions or ensuring fair compensation.

Client dashboard showing real-time cost of ad-hoc requests, nudging them to use proper processes

Target Users: Solo consultants, accountants, designers, lawyers, and other hourly professionals with high-touch, ad-hoc clients
