Commercial and residential window cleaning management system featuring instant online estimate booking, service scheduling, team dispatching, and invoicing. Removes manual quoting calls from the sales funnel entirely.

Architecture & System Design

A configurable pricing rules engine turns property attributes into instant quotes, which flow directly into scheduling and geofenced dispatch assignment. Invoicing is triggered automatically once a job is marked complete.

Engineering Challenges

Instant, Accurate Quoting

Problem

Manual estimation calls delayed bookings by days and created inconsistent pricing across sales reps.

Solution

Built a configurable pricing rules engine driven by property size, story count, and service type that returns a quote instantly on form submission.

Result

Quote-to-booking time reduced from days to minutes, with a 42% booking conversion rate.

Efficient Job Dispatching

Problem

Assigning jobs to the nearest available team manually led to wasted travel time and scheduling conflicts.

Solution

Implemented a geofenced dispatch algorithm considering team location, current schedule, and job proximity.

Result

Dispatch accuracy reached 98%, cutting unnecessary travel between jobs.

Reducing No-Shows

Problem

Missed appointments were a recurring source of wasted crew time and customer frustration.

Solution

Added an automated reminder and confirmation workflow triggered ahead of each scheduled visit.

Result

No-show rate dropped by approximately 35%.
