Jobkore is estimating, invoicing, and payment software for construction and field-service contractors. It is built for solo operators and small crews across 40 trades — general contracting, remodeling, electrical, plumbing, HVAC, roofing, painting, landscaping, and more. Quote a job from the truck, send it for e-signature, turn the accepted estimate into an invoice, and get paid by credit card or ACH bank transfer through Stripe. Jobkore adds zero markup on top of Stripe's standard processing rates. Hank AI, the assistant built into Jobkore, turns field notes — typed text, voice memos up to 15 minutes, photos, and PDFs — into organized, priced line items. It also edits any estimate, invoice, or change order live by chat: add a line, set a price, restructure a section, rewrite the scope. The contractor reviews and approves everything before it reaches a client. Beyond documents, Jobkore tracks projects (contract value, invoiced, collected, unbilled, and outstanding), handles change orders as their own approved and signed documents with AIA G701-style contract reconciliation, and keeps subcontractor balances so a contractor always knows what they owe. One-way sync to QuickBooks Online is included at no extra cost. The entire product — app, estimates, invoices, PDFs, and client emails — works in both English and Spanish. Jobkore is one plan at $29 per month or $290 per year. Every feature is included: no tiers, no per-seat pricing, and no add-on charges. Every account starts with a 14-day free trial that requires no credit card. Jobkore was built by Steve Reinhardt, a licensed general contractor in Oregon who spent 20 years in web development before starting his own construction company.
