Phase0

What Is Phase0?

Phase0, formerly known as Compa, is an AI-powered platform for architecture and engineering firms. It covers cost planning and tendering (AVA), fee management and time tracking (HOAI), and construction site documentation, helping planners manage their projects in one place. It is built specifically for the AEC industry and aligns with German standards (VOB, HOAI, DIN 276).

What Is Phase0 Best For?

The software is best known for its AVA module, which combines cost estimation, tendering, and invoice correction into a single workflow. It supports construction teams in creating DIN-aligned project budgets and managing bids, reducing manual calculation errors and improving financial clarity. It particularly helps with accurate cost breakdowns, maintaining consistency across projects through precise invoicing.

Phase0 Use Cases

Based on our analysis of Phase0's current capabilities, we have identified key scenarios where the software is a good fit for engineers and architects:

Interior Design Firms Seeking An All-In-One Construction System

Interior designers use Phase0 to manage the transition from creative concept to technical construction. The browser-based environment lets designers oversee cost tracking and site progress in one place. For a lead architect, this centralization frees up time to focus on translating design intent into buildable plans while keeping control over project timelines and resource allocation.

Architectural Firms Looking to Streamline The Tendering Process

Architectural firms adopt Phase0 to simplify the often fragmented process of soliciting and evaluating contractor bids. The platform allows architects to distribute digital tender documents and compare incoming offers within a standardized framework. This structured approach helps project managers identify qualified contractors more quickly and supports a transparent procurement phase.

Planning Officers Managing Cost Plans

Public and private planning officers use Phase0 to maintain oversight of project budgets, from the initial estimate through final billing. The system enables detailed cost breakdowns, allowing officers to track expenditures against original projections in real time. This financial visibility helps construction managers spot potential overruns early and adjust before they escalate.

Lone Architects Handling Administrative Workload

Lone architects often use Phase0 to take some of the load off repetitive documentation and reporting tasks that pull time away from design work. The software supports the generation of site logs, meeting minutes, and compliance records aligned with legal and professional standards. For solo practitioners, this means more transparent, audit-ready records and fewer hours spent on administrative work.

Is Phase0 Right For You?

Construction teams often struggle with scattered documentation, delayed reporting, and inconsistent cost tracking across project stages, which leads to coordination gaps and budget inefficiencies. Phase0 addresses these challenges through AI-driven reporting, structured cost estimation, and project control functionality, bringing the office and the site into a shared view.

Trusted by 800+ architecture offices, the platform is GDPR-compliant and supports secure project execution.
