As answered by people managing JOBKORE and Sing App React Java.
JOBKORE's answer
Built by a licensed contractor who needed a simpler tool. Fully bilingual (English/Spanish), AI-powered estimate organization, change orders with separate approval workflows, and zero additional payment processing fees. Everything included for $19/mo — no per-user charges, no upsells.
JOBKORE's answer
$19/mo gets you everything — estimates, invoices, payments, QuickBooks sync, and AI. Competitors charge $39-199/mo and add extra fees for payments, QuickBooks, or additional users. Jobkore charges nothing on top of Stripe's standard rate. No other contractor software offers full Spanish support or AI estimate organization at this price.
JOBKORE's answer
Solo contractors, small crews, and service businesses in the trades — general contractors, painters, landscapers, plumbers, electricians, roofers, drywall installers, remodelers, and similar. Especially Spanish-speaking contractors in the US who are underserved by existing software.
JOBKORE's answer
Jobkore was built by Steve Reinhardt, a licensed contractor in Oregon. After years of overpaying for bloated software or stitching together spreadsheets and free tools, he built the estimating and invoicing tool he actually wanted to use — simple, affordable, and designed for how contractors actually work in the field.
JOBKORE's answer
React, TypeScript, Node.js, Express, PostgreSQL, Prisma, Stripe, Cloudflare R2, and Claude AI (Anthropic) for the Hank AI feature.
