Wasted hours
Each manual budget takes 8 to 20 hours. Multiply that by your yearly projects, and it's entire weeks spent on spreadsheets.
The AI that prevents budget errors,
not just drafts them
Budgets built on real data, real-time cost control and a focus on your margin.
Upload your plans and AI generates the budget. Manage subcontractors, invoices, and certifications in real time. Track every euro from the first line item to the last payment.
Free plan: 1 active project and 3 AI budgets per month. No card required.
Verified prices from real works. See where they come from.
Real-time cost controlSubcontractors & certifications
What does an inaccurate budget cost you?
The problem is global: slow payments cost US construction $280B in 2024 (14% of total construction spend), and 40% of construction projects in Spain end in financial disputes. The root cause is always the same: inaccurate budgets, untracked costs, and zero financial visibility.
Invisible overruns
Without real-time subcontractor and invoice tracking, cost overruns are discovered when it's too late to fix them.
Fragmented tools
Budgets in Excel, invoices somewhere else, certifications on paper. Every step is an opportunity for error.
Solution
One place to budget, control, and get paid
CostPact combines AI-generated budgets, subcontractor and invoice tracking, certification management, and a full financial dashboard. From the first estimate to the last payment, every euro is tracked.
AI that budgets from your documents
Upload plans, specifications, or site photos. The AI extracts the scope and generates a detailed budget cross-referenced with standardized work items from 13 years of completed projects.
Real-time cost control
Subcontractors, purchase orders, invoices, and certifications in a single panel. Committed vs. invoiced always visible. No side spreadsheets.
From renovation to development
A single €30K renovation or a €10M residential development. Typologies, units, per-unit modifications, and common areas. The same platform scales with you.
You never miss a line item
When you add a line item, the AI surfaces the dependent ones it usually pulls in. It catches omissions before they become an overrun on site.
A clean view for your client
The same budget in a simplified, jargon-free version, ready to present. You see every line item; your client sees what they need to decide.
