Sellsy
The 100% French CRM, invoicing and cash flow suite for SMEs who want to centralize everything
Overview
Sellsy is a SaaS platform founded in La Rochelle that brings together CRM, quotes, electronic invoicing, cash flow tracking and pre-accounting in a single tool, a rarity on the French market. Over 19,000 SMEs use it to avoid fragmentation between a CRM (HubSpot), an invoicing tool (Pennylane) and a cash flow spreadsheet. The solution is an accredited platform (Plateforme Agréée) for the 2026 electronic invoicing reform in France.
Sellsy AI handles automatic categorization of receipts and bank-invoice matching. Standard Invoicing plans start at €39/user/month (or €29 the first year until June 2026); Sales+Invoicing suites reach €49-119/user/month. The per-seat model can quickly strain budgets for teams of 5+ people.
Our verdict
The best all-in-one French tool for a commercial SME (5 to 50 employees) that invoices in France and wants to merge CRM and financial management without multiplying subscriptions. Ideal for sales teams with long cycles (quotes, follow-ups, collections). Avoid if you do not need CRM: Pennylane or Tiime are more affordable for accounting alone.
