What Inpact does

INPACT is a privately held French software and services company founded in 1979 in Lyon, specializing in payroll management and HR information systems (SIRH) for small and medium-sized French enterprises. The company serves more than 500 active clients and processes over 20,000 pay slips per month across the quick-service restaurant, hospitality, and general business sectors. INPACT's core product is the INPACT+ SaaS platform, which was launched in 2025 as a unified ecosystem for payroll, HR management, document handling, electronic signature, employee onboarding, and workforce analytics. The platform is built on top of Silae, the leading French SaaS payroll engine processing more than 8 million pay slips per month, with INPACT operating as a certified integrator and Alliance Top-tier partner. INPACT has also developed proprietary modules including the Tableau de Main d'Œuvre (TMO), a workforce analytics dashboard purpose-built for the quick-service restaurant vertical.

The company's revenue model is anchored in recurring SaaS subscriptions sold under two principal commercial offerings. The first, Mise à Disposition (MAD), gives clients licensed access to the Silae payroll software to operate autonomously while INPACT provides expert support and compliance assurance on a subscription basis. The second, Externalisation, is a full-service payroll outsourcing model in which INPACT experts handle data entry, calculation, declarations, and production for higher recurring fees. Pricing is quote-based, tiered by employee count (from 5-person TPEs up to 2,500+ employee enterprises), and billed annually. INPACT also generates ancillary revenue from QUALIOPI-certified training services (Silae Level 1 and 2 training and thematic workshops) eligible for OPCO funding, as well as from custom ecosystem build-outs for multi-establishment clients.

INPACT distributes exclusively through a direct sales and inside sales motion with no reseller or partner channels for client delivery. The company is led by three associates: François BIZOT as Président Directeur Général, Karla BIZOT as Directrice Service Client & RH, and Serge MARCHANT as Directeur Technique. Geographic focus is exclusively domestic, with all operations and customers in France. The company is a private SAS (Société par Actions Simplifiée), is founder/management-owned with no disclosed external funding, and operates from B Corp-certified offices at Newton Offices in Lyon.

Revenue model

1. SaaS Subscription — Payroll & HRIS Platform: INPACT generates recurring subscription revenue from its INPACT+ SaaS platform. Pricing is based on the number of employees (number of staff), selected modules, and the level of service accompaniment desired (Mise à Disposition vs Full Outsourcing). The company offers a personalized quote within 24 hours. Subscriptions include platform access, automatic regulatory updates, security compliance, and ongoing support.
2. Mise à Disposition (MAD) — Managed Software Access: The Mise à Disposition (MAD) service provides clients with licensed access to the Silae payroll software, which they operate autonomously under INPACT's expert guidance. Clients retain control of data entry and bulletin validation while INPACT provides ongoing expert support and compliance assurance. This is a recurring subscription model with tiered pricing based on employee count and module selection.
3. Full Payroll Outsourcing: Complete delegation of payroll processing — INPACT experts handle data entry, calculation, declarations, and production. Clients deposit data via the secure platform, INPACT processes everything in Silae with guaranteed compliance, and clients validate pre-bulletins. This full-service model commands higher recurring fees than MAD, with pricing based on employee volume and complexity.
4. Training Services: INPACT provides certified training programs (QUALIOPI-certified) including Level 1 & 2 Silae training, thematic workshops (DSN, absences, sector-specific topics), and customized documentation. Training is eligible for OPCO funding, adding a professional services revenue stream on top of subscriptions.

Recent moves12 records

Expansion highlights5 records

Direct peers

• PayFit: French payroll and HRIS SaaS company serving the same SME buyer (typically 5–2,500 employees) with a self-serve, PLG-led motion. PayFit competes head-to-head for the modern French SME payroll customer and represents INPACT's most direct PLG challenger.
• Nibelis: French HR and payroll SaaS provider offering payroll, HRIS, and time management for SMEs and mid-market. Nibelis operates as another top-tier Silae ecosystem peer serving overlapping customer segments with comparable subscription + service monetization.
• HR Path: French HR and payroll consulting/implementation firm that partners with multiple payroll vendors (including Silae, Workday, SAP SuccessFactors). HR Path overlaps with INPACT in the SME/mid-market implementation and managed-services segment.
• Talentia Software: French provider of HR and payroll software for mid-market companies, offering HRIS, payroll, and talent management modules. Talentia is a comparable French HR/payroll SaaS peer competing for similar buyer profiles.

Broad incumbents

• Sage (France): Global accounting and payroll incumbent with strong French market presence. Sage serves the same SME payroll buyer with both SaaS and on-premise offerings and competes on price/scale against INPACT's boutique expert model.
• Cegid: Major French ERP and HR/payroll software incumbent serving mid-market and enterprise. Cegid competes in French payroll at greater scale, with a broader product portfolio, and represents the dominant incumbent in the same customer base INPACT targets.
• SD Worx: European payroll and HR services provider active across multiple countries including France. SD Worx combines payroll software with managed services and competes with INPACT for mid-market French accounts seeking pan-European capabilities.
• Sopra HR: HR software division of the Sopra Steria group, providing HR/payroll solutions to mid-market and large French enterprises. Sopra HR competes with INPACT at the larger end of INPACT's addressable market with greater enterprise IT integration capabilities.
• ADP (France): Global payroll and HR services giant with French operations. ADP competes primarily in the larger end of the SME and mid-market segment where INPACT also plays, offering a combination of SaaS technology and managed services similar to INPACT's Externalisation offering.

Others

• Silae: The underlying payroll SaaS platform on which INPACT is built. Silae both enables INPACT's go-to-market (as Alliance Top partner) and represents a channel conflict risk, since Silae also sells directly to large accounts and recruits competing integrators within the same Top 100 network.
