Sellsy

What Sellsy does

Sellsy is a French cloud-based SaaS provider of an integrated CRM and business management suite targeting small and medium enterprises (TPE/PME), independents, and accounting professionals (experts-comptables) across France and, increasingly, the Iberian Peninsula and broader European/Mediterranean region. Founded in 2009 in La Rochelle by Alain Mevellec and Frédéric Coulais (initially as MyFacture), the platform unifies four core modules — Vente (CRM/sales pipeline), Facturation (invoicing and pre-accounting), Marketing (campaigns, automation, lead scoring), and Trésorerie (treasury and cash management) — into a single environment with native integrations to Google Workspace, Microsoft 365, Stripe, PayPal, GoCardless, Pennylane, and Make, plus a public JavaScript SDK API. Sellsy holds France-specific regulatory assets including Plateforme Agréée status for mandatory electronic invoicing (September 2025) and ISO/IEC 27001:2022 certification (August 2025), with all data hosted on Scaleway infrastructure in France.

The company operates a hybrid go-to-market combining product-led growth (15-day free trial without credit card), sales-assisted enterprise demos, and a channel program anchored on experts-comptables resellers. It has scaled to 150+ employees (with R&D at roughly half of headcount), 50,000+ users, and 23,000+ paying clients, and has cumulatively facilitated €22 billion in invoicing since inception. Sellsy's revenue model is subscription-based SaaS with tiered plans segmented by company size (Indépendants, TPE 1-5, PME/ETI 6+) on monthly billing, with pricing not publicly disclosed for paid tiers. The company executed three acquisitions (RocketChart in March 2022 for treasury management, Quipu in November 2022 for Spanish market entry, and Sendethic in October 2023 for marketing automation) and raised €62M+ in funding across rounds including a €55M growth investment from PSG (Providence Strategic Growth) in January 2022. In 2025, Sellsy was acquired by TeamSystem (backed by Hellman & Friedman) to anchor a pan-European SME digital transformation platform spanning Europe and the Mediterranean.

Emerging players

• Brevo: French-origin marketing automation and CRM platform for SMBs. Competes with Sellsy's marketing module and overlaps in CRM and email/SMS campaign use cases for the same French buyer base.

Direct peers

• Pennylane: French fintech/accounting platform for TPEs/PMEs offering pre-accounting, treasury, and invoicing with strong product velocity. Directly overlaps with Sellsy's invoicing and treasury modules and competes head-to-head for the same French SME buyer, though Pennylane does not yet offer a full CRM suite.
• Odoo: Belgian-origin open-source ERP/CRM suite offering integrated CRM, invoicing, marketing, and inventory modules for SMEs globally. Competes directly with Sellsy's all-in-one positioning and is widely adopted across European SMEs, with significant traction in France.
• Zoho: Global all-in-one SaaS suite for SMBs covering CRM, invoicing, email marketing, and finance at competitive price points. Directly comparable to Sellsy's bundling strategy, frequently selected by TPEs/PMEs seeking an affordable integrated alternative.
• Pipedrive: SMB-focused CRM platform popular with European SMEs for sales pipeline management. Competes for the same PME/ETI buyer evaluating CRM-centric solutions, though it lacks Sellsy's invoicing and treasury modules.
• Divalto: French ERP/CRM vendor targeting French TPE/PME/ETI with integrated business management software. Directly comparable as a French alternative for SMEs seeking localized, sovereign business software suites.

Broad incumbents

• HubSpot: Global CRM and marketing platform with deep mid-market penetration, including France. While not a TPE-focused platform, HubSpot increasingly targets the same PME/ETI customer with a broader feature set and stronger brand recognition, posing an upgrade-path threat.
• Sage: UK-headquartered global provider of accounting, payroll, and ERP software with strong French SME presence (Sage Active). Overlaps significantly with Sellsy's invoicing and treasury modules and is the incumbent French TPE accounting software.
• Salesforce: Global enterprise CRM leader with growing mid-market and SMB offerings. While typically aimed at larger customers, Salesforce's brand and ecosystem pressure Sellsy's PME/ETI tier and influence accounting-partner recommendations.
• Microsoft Dynamics 365: Microsoft's enterprise/mid-market CRM and ERP suite, often adopted by PMEs/ETIs seeking integration with Microsoft 365 (a Sellsy partner). Competes at the upper end of Sellsy's PME/ETI segment.
