ProJobCalc — for journalists & analysts.

ProJobCalc is bid proposal software for independent contractors. The flagship feature is an AI bid proposal generator that writes a complete, professional proposal in under 30 seconds from a project description. Free tier includes 40+ trade calculators (HVAC, roofing, electrical, plumbing, painting, and more); Pro tier ($19/mo) unlocks the AI proposal generator, voice estimator, branded PDFs, unlimited saves, and a clearer integration surface for partner workflows.

ProJobCalc is an independent-contractor productivity tool built by Mitch Reise, an LA-based solo founder. It exists because most trades software is priced for companies with 10+ employees and assumes you have a dispatch board, a call center, and a marketing manager. ProJobCalc strips to the part contractors actually use — winning the bid — and costs $19/month for Pro. It pairs a free, ungated suite of 40+ trade-specific calculators with an AI Bid Proposal Generator and a hands-free voice estimator (“truck mode”) for quoting from the road. The platform now also publishes a public integrations page, JSON manifest, OpenAPI 3.1 contract, and AI-readable llms.txt files so partners and answer engines can evaluate the product without private access. Roughly 1/4 the price of Jobber for the same proposal workflow.

Mitch Reise is the founder and sole operator of ProJobCalc. Background in software engineering; built ProJobCalc after spending 18 months helping family members in trades navigate proposal-writing software that was either “too expensive” (ServiceTitan-class) or “too generic” (Microsoft Word + emailed PDF). The bet: a single-operator SaaS, priced transparently, that does the proposal layer extremely well and resists the temptation to grow into everything else.

Mitch also operates wisp.video (one-time-view encrypted video) and the hugin.studio Reddit scam scanner — same operator-pattern, different problem domains.

• The contractor-software pricing reset. Most field-service SaaS prices in the $50–$300/mo range per seat. ProJobCalc at $19/mo flat is a deliberate counter-position. (See /compare/jobber for the math.)
• Voice as the contractor interface. Truck mode (“Sage”) lets a contractor walk a site, narrate the scope, and have a structured estimate ready by the time they’re back in the truck. Adjacent to Twilio + Anthropic Claude.
• Single-operator SaaS as a business model. One person, no VC, transparent pricing, no growth gymnastics. Counter-narrative to the “every SaaS must scale to enterprise” default.
• Contractor software with open edges. ProJobCalc stays focused on proposals, estimates, and invoices while exposing a machine-readable integration contract for CRMs, accounting tools, automations, and partner workflows. See /integrations for the public launch surface.
• AI for working-class professional services. Most AI-productivity stories are about knowledge work (lawyers, marketers, programmers). The trades use it differently — narrate from the field, get structured output for someone else to act on. Different ergonomics.
