SparkQuote Estimator - 2026 Pricing, Features, Reviews & Alternatives

SparkQuote Estimator is a cloud-based, browser-native electrical estimating platform covering the full bid workflow from PDF plan upload to branded proposal delivery. Designed for electrical and low-voltage contractors in residential, light commercial, tenant improvement, and low-voltage markets, it targets shops of 1 to 50 people, including owner-estimators, single full-time estimators, and small estimating teams. No installation is required; the application runs on Windows, Mac, phone, and tablet.

SparkQuote Estimator performs AI-driven takeoff directly from uploaded PDF plan sets. The system reads the drawing legend, identifies electrical sheets, determines scale, and counts receptacles, switches, fixtures by type tag, panels, disconnects, and data outlets. Every detected device is highlighted on the sheet for user review, and low-confidence detections are flagged rather than silently included. Conduit and cable runs drawn to scale are measured automatically. Plan images and text are processed via an external AI API (Anthropic) as disclosed in the vendor's terms of use. Beyond takeoff, the platform provides an editable starter library of electrical labor units and assemblies with three labor columns (normal, difficult, very difficult), labor factors adjustable by job, area, or line item, and condition adjustments for ceiling height, remodel, and occupied space. Supplier price lists import by CSV. Estimates support add and deduct alternates, unit prices, and bid breakdowns by area, system, phase, cost code, and drawing. A plan revision comparison tool generates a delta estimate of add and deduct lines. The integrated proposal builder accepts a user logo, inclusions, exclusions, and alternates, and exports to PDF and Excel. Free NEC calculators covering wire size, voltage drop, conduit fill, box fill, load calculation, watts to amps, panel schedule, and bid calculation are available without an account. On the Team plan, estimate-versus-actual hour tracking by cost code is available, and the system suggests revised labor units based on recorded job hours.
