The core of the platform

Everything a modern construction company needs

Not a generic ERP — it speaks the language of construction. Tenders, contracts, performance certificates, deductions, partner scoring, leave, fleet, invoicing — all in one place.

Cloud

Cloud-based

Accessible anywhere, zero install. iPad on site, laptop in the office, phone in the car — same experience.

Big Data

Big data & reports

Suggestions and company-wide reports built on years of tender and contract data. No more hunting through Excel files.

Audit trail

Full traceability

Every certificate, every signature, every document — audit-grade. Who approved what, when? One click.

Documents

Automated document generation

Contracts, purchase orders, performance certificates from templates based on real data. 20 minutes of paperwork → 20 seconds.

AI chat assistant

Ask what last year's budget was broken down per subcontractor — the system answers in your language in seconds.

AI on demand

Delegate tasks to the AI: "compare these two offers", "draft a reminder to the project manager". For every action.

ATMOSCollective intelligence

Your company's knowledge
at your fingertips.

ATMOS AI is not a bolted-on chatbot. It has real-time access to project data, contracts, offers, yesterday's meeting minutes.

Years of experience, data from hundreds of projects — available in a single question. That's collective intelligence. That's what makes your company smarter every year.

Client Stargate

Your clients see project status, deductions, and documents live.

Leave management

Multi-level approvals, calendar, balances, Hungarian holidays built in.

Fleet & inventory

Custom development

Need something specific? We build it. No workarounds — we adapt to you.

Why not the usual solution?

Construction is not retail, not a call center, not pharma. A construction ERP speaks the language of construction — certificates, tenders, retention, deductions. Others don't.

Generic ERP

"Does everything, costs everything."

  • Yearly license fees in the millions, per user
  • Months of customization with consultants, hourly rates
  • Generic ERP — construction specifics are your problem
  • Updates often break your customization

Generic CRM

"Good for notes — until there's a contract."

  • No tender / certificate / contract flow
  • No construction document templates
  • No subcontractor Stargate
  • Can't handle financial deductions or partner scoring

ATMOS ERP

"Built for construction, from day one."

  • Construction-specific certificates, tenders, deductions, scoring
  • Subcontractor and client Stargate included
  • AI assistant with access to the entire company dataset
  • Customizable with real development — Hungarian team

About

Construction ERP — Hungarian-tailored business management

ATMOS is a cloud construction ERP and business management system built for Hungarian contractors, general contractors and subcontractors. The goal: manage the entire tender → contract → performance certificate → invoicing flow in one system, eliminating the spreadsheet sprawl and parallel databases.

Construction-specific features — reverse VAT, subcontractor portal (Stargate), performance-certificate templates, warranty tracking, bank-guarantee registry — are core, not add-ons. Unlike generic ERPs, no months-long customization project is needed: ATMOS works on day one for a Hungarian construction company.

A built-in AI assistant helps daily work: the Claude-based chat knows your data, fills contract templates with one click, compares tenders apple-to-apple, and writes executive summaries. SaaS model: every update is in the monthly fee, no separate rollout project, always up-to-date.

Projects and tenders

Tenders in one interface: RFQ, bid intake, apple-to-apple comparison, decision, contract generation — every step logged. Subcontractors see their tasks on the Stargate portal.

Contracts with Hungarian templates

Parametric templates (PPP, civil, reverse VAT) — one click to a signable contract. Every version is logged, magic-link signed, fully audit-trailed.

Invoicing and accounting export

Billingo and Számlázz.hu integration. One click from TIG to invoice. NAV-compliant XML / Excel export, supported by every popular Hungarian accounting program.

AI reports and cash flow

Executive dashboard, cash-flow view, partner ratings, warranty tracking. Monthly AI-written summary of the numbers, highlighting risks.

Simple, +_<]^_-}#_\ pricing.

0 HUF setup fee, no lock-in, 14-day free trial.

Bank-grade protection

FAQ

Frequently asked questions

Construction ERP, business management, AI — everything you need to know.

A construction ERP is a business management system tailored to contractors, general contractors and subcontractors: tender management, contracts, performance certificates, completion notices, reverse-VAT invoicing, partner ratings and warranty tracking. A generic ERP (SAP, Dynamics, MiniCRM) can only do these after heavy customization, often at 100x the cost.
