Those Who Build America

Materials, accounting, payroll, safety, and field ops β€” all in one cloud platform. No more spreadsheets. No more Sage 100 headaches.

Problems Every Contractor Knows

Spreadsheet Chaos

POs in Excel, inventory in Google Sheets, payroll on paper. Nothing talks to each other. One mistake cascades everywhere.

Sage 100 Is Stuck in 2005

$5,000+ upfront, 4-8 weeks setup, no mobile app, no field access. Your crew can't use it from the jobsite.

Language Barriers

Your crew speaks English, Korean, and Spanish. Your software only speaks English. Miscommunication costs money.

No Field Visibility

Project managers in the office have no idea what's happening on-site. Photos, inventory, and schedules live in different apps.

Frequently Asked Questions

What is construction ERP software?

Construction ERP (Enterprise Resource Planning) software integrates all business operations β€” purchasing, inventory, accounting, payroll, safety, and project management β€” into one platform. Instead of managing 5-10 separate tools, everything lives in one system.

How is Gonsius Pro different from Sage 100 Contractor?

Gonsius Pro is cloud-native (no install), mobile-first (field app included), multi-language (EN/KO/ES), and starts at $24/user/month with no upfront cost. Sage 100 requires on-premise installation, has no mobile app, and costs $5,000+ upfront.

Can I try it before paying?

Yes. Gonsius Pro offers a 15-day free trial with full access to all features. No credit card required. Your account includes demo data so you can explore immediately.

Does it work on phones and tablets?

Yes. Gonsius Pro includes a dedicated mobile field app for site photos, inventory checks, GPS time clock, repair tracking, and crew schedules. It's a Progressive Web App (PWA) that works on any device.

Is my data secure?

Absolutely. Gonsius Pro uses Row-Level Security (RLS), AES-256 encryption, and AWS infrastructure. Your data is isolated per tenant β€” even our developers cannot access your data without authorization.
