Sellsy is a French CRM platform designed for very small to medium-sized businesses, combining sales, invoicing, pre-accounting, treasury, and marketing in one secure interface. It streamlines customer relationship management, automates invoicing and payments, supports marketing campaigns, and offers real-time cash flow monitoring. With integrated AI and numerous third-party integrations, Sellsy helps businesses optimize operations, improve client relations, and manage financial tasks efficiently while ensuring data security and compliance.

Sellsy attempts to cover everything from CRM to invoicing and marketing, with strong French data sovereignty and a robust catalog and stock management suite. Its ability to create purchase orders from sales quotes streamlines procurement for project-driven teams, and integrations with tools like Google Workspace and Stripe make it versatile for daily operations. Businesses needing granular control over stock or those prioritizing local hosting will find value here.

However, navigation quickly becomes cluttered, and the absence of a centralized project view severely limits its usefulness for profitability analysis or complex project oversight. Progress invoicing is frustratingly unreliable, and key modules come as costly add-ons. Ultimately, Sellsy feels more like a patchwork of features than a seamless solution. For those seeking comprehensive project management or intuitive workflows, alternatives may serve you better.
