Special Feature Rating & Criticism Ideal for Sovereign French Cloud (GDPR compliant) with integrated e-invoicing. 4.2/5 stars. Praised for its range of functions; criticized for its learning curve and API stability. European SMEs (TPE/PME) that want to centralize sales and accounting.
Sellsy positions itself in 2026 as one of the leading European alternatives to US giants like HubSpot. The software solves the main problem for many small businesses: the fragmentation of data across different tools for sales, invoicing, and marketing. Sellsy offers a central platform that covers the entire cycle from lead to payment. The conclusion: A powerful, legally compliant solution for growing teams, but one that requires a certain amount of training.
In the modern workplace, companies use Sellsy to coordinate hybrid sales teams. A typical scenario is the automatic conversion of a won lead into a digital offer, which the customer pays for with a click, after which accounting immediately receives the correct invoice. This saves up to 25% of administrative time compared to isolated, standalone solutions.
