Viaco - Once For All

What Viaco - Once For All does

Viaco is a brand of the Once For All group (OFA Group SAS), a B2B SaaS platform focused on supplier compliance and construction site digitalization for the French BTP (construction) sector. The platform's core offering consists of two integrated solutions: an online pre-qualification questionnaire for third-party suppliers covering ethics and RSE/ESG (Corporate Social Responsibility) criteria with automatic attestation generation, and the Totem connected construction site panel, which replaces traditional sticker-based site displays with a real-time digital panel showing workers present on site. These solutions are designed to address French regulatory mandates including mandatory site display requirements and anti-hidden work legislation, as well as Loi Sapin 2, CS3D, and CSRD compliance obligations for main contractors.

The underlying technology is a multi-tenant SaaS platform accessible via app.viaco.fr and integrated into the broader Once For All client portal, with self-service workflows and dedicated phone support. The platform sits within a broader group ecosystem of eight retained brands covering legal attestations (Attestation Légale), subcontractor compliance (Actradis), worker authorizations (Hiveo, Sywa), marketplace (Bâtisseur de Relations/Marketplace), legal declarations (Déclarations Légales), and administrative document management (Batis). The group has incorporated AI capabilities through the 2024 acquisition of Bidwork Software Ltd, an AI-based tendering tool.

Revenue is generated through subscription-based SaaS access to platform features, with a freemium model for the standardized pre-qualification questionnaire and paid tiers for full platform access. The customer base is a two-sided market comprising main contractors (Donneurs d'ordres) who need to pre-qualify subcontractors and suppliers, and subcontractors/suppliers who complete compliance documentation and source new projects. The Once For All group serves 350,000+ B2B clients across 12 countries in Europe and Latin America, with 950+ employees globally (180+ in France), and processes 140,000+ data points covering competencies, compliance, and risk status. The group is owned by Fortius Bidco Group Limited, a UK-incorporated holding entity.

Regional players

• Mezzoteam: French collaborative document-management and approval-workflow platform purpose-built for construction project compliance (incl. procédure d'agrément). Directly comparable to Once For All's PanDA approval module and Batis document management.
• Alobees: French construction-site management SaaS focused on mobile site tracking, worker presence, and project reporting. Regional peer operating in the same French BTP market and addressing overlapping on-site compliance workflows.

Direct peers

• Altius: UK vendor assessment and compliance platform, also part of the Fortius group alongside Constructionline. Closely comparable in core activity — supplier compliance verification for construction and related sectors.
• Alcumus: UK vendor risk management and compliance certification platform serving construction, facilities management, and rail — directly comparable to Viaco's supplier pre-qualification and compliance document verification.
• Constructionline: UK-based construction supplier pre-qualification platform, a sister brand of Viaco within the Fortius/Once For All group. Operates the same supplier-compliance model in the UK market, making it the most directly comparable peer.
• Builder's Profile: UK supply-chain SaaS for construction pre-qualification, acquired by Fortius in 2020. Sister brand within Once For All with overlapping supplier-qualification and risk-scoring functionality.

Broad incumbents

• Coupa Software: Cloud-based business spend management platform with supplier qualification and contract compliance capabilities. Adjacent competitor that could push down into vertical-specific BTP compliance.
• SAP Ariba: Global leader in procurement and supplier-management SaaS, including supplier qualification and risk modules. Represents the upper bound of competition for any B2B supplier-compliance platform.
• Procore Technologies: Largest publicly-traded construction management SaaS platform, covering project management, quality/safety, and tendering. A broader incumbent whose pre-qualification and project-bidding modules overlap with Viaco's RFP and compliance offerings.
• Ivalua: French-headquartered source-to-pay SaaS platform covering supplier qualification, contract management, and procurement. Comparable at the procurement-compliance layer, though much broader in scope than Viaco.
