CAS-TX · Software studio
Software the trades
actually needed — and a few things beyond.
CAS-TX builds practical tools for contractors and small businesses: estimating, field capture, timekeeping, books, phone systems, and more. Some are live today, some are open source, all built to actually get used.
The portfolio
Projects
Everything the studio is building — live products, open source, and works in progress.
Walk the job, talk it through, get a scope of work + bill of materials.
Field-capture app for contractors: talk your way through a site walk and spoken part specs stream into a priced bill of materials, matched to your catalog.
Estimating and bidding that actually fits how contractors work.
The estimating and bidding platform at the center of the suite — products, pricing, and proposals in one place.
An AI-native business phone system you own outright.
Open-source, self-hosted phone system — a modern replacement for 3CX with a real-time AI receptionist, built on Asterisk with a full TypeScript control plane.
AI takeoff you can trust — count devices off the drawings.
A tiled AI takeoff engine that reads plan sets and produces trustworthy device counts (electrical, data/telecom, security, fire alarm).
GPS proof-of-presence timekeeping + certified payroll.
Technician time tracking with geofenced GPS punches, anti-fraud, offline punch queue, job costing, and WH-347 certified payroll.
Contractor-native double-entry books — the money half of the Crew suite.
Double-entry accounting built for contractors: invoicing, cash + accrual P&L, purchase orders, Stripe payments, and per-job profit synced from CrewClock.
Turn footage into a book, screenplay, or animation.
Ingest videos and research, then let a top-tier model write a chaptered book, a screenplay, or an animation script — with exports to DOCX, PDF, Fountain, and more.
A low-fee marketplace where creators keep more.
A creator marketplace with branded shops and a shared storefront, a seller dashboard, and cart/checkout — designed around low fees.
Warehouse and project inventory with barcodes.
Track warehouse and per-project inventories with barcode scanning and generation, behind a simple login.
Open source
Take it and run it.
The open-source projects are yours to self-host, inspect, and modify — no per-seat fees, no lock-in. Grab the code, run it on your own hardware, own it outright.
An AI-native business phone system you own outright.
Open-source, self-hosted phone system — a modern replacement for 3CX with a real-time AI receptionist, built on Asterisk with a full TypeScript control plane.
More projects open up over time as they mature.
