Millisave vs Sellsy: CRM, Quotes and Prospecting
Sellsy is a familiar name for French-speaking small businesses that want customer relations, quotes and invoices in one tool. Millisave is less a back-office tool and more an AI-powered platform that helps a company win customers and keep its buying costs in check. This page puts them side by side for teams in France and French-speaking markets.
What Sellsy is built for
Sellsy describes an all-in-one suite for CRM, invoicing, e-invoicing and payments, aimed at French-speaking SMEs, with programmes for accountants and resellers. The sales part covers contact management, quotes with e-signature and opportunity tracking. The invoicing part covers quotes and invoices, purchase orders and delivery notes, purchasing, pre-accounting, automatic payment reminders and online payment, and electronic invoicing through an accredited platform (Plateforme Agréée). Marketing tools include landing pages, email and SMS campaigns, automation and lead scoring. A cash management area offers bank synchronisation and forecasting, and an AI feature is called Sellsy IA.
The vendor says the software is designed, operated and hosted in France, with French-based support, and that it is now part of the TeamSystem group. Public sources place its registered headquarters in La Rochelle. The site is offered in French, English and Spanish.
Where Millisave starts
Millisave focuses on the sales cycle of companies that sell physical products to other businesses. Sales Engine finds and scores target companies, the CRM manages pipeline stages with probabilities and a forecast, and Sales & Marketing sends campaigns and quotes and shares an e-catalogue. Every AI result is explained, and a person decides what to do with it.

How the rest of the Millisave platform adds up
Because Millisave also runs the buying side, a quote and a supplier offer can be compared on the same product record. A distributor can see what a product costs through Source to Pay while quoting it through Sales & Marketing. Sales Engine proposes the right sectors and countries, CRM keeps the pipeline, and Pilotage & Gouvernance shows KPIs and pending approvals in one place. The platform is modular: you can start with prospecting and CRM and add purchasing later. Nothing the AI proposes bypasses approvals or budgets.
Fit for French teams
Sellsy has a strong France story: French hosting, French support and an accredited e-invoicing platform. Millisave offers a French interface and counts France among its markets, with budgets in euro, but it does not describe French e-invoicing in its public documentation. If you must send e-invoices from your sales tool, check that requirement first.
Who should choose which
Choose Sellsy if you are a French-speaking SME that wants quotes, invoicing, e-invoicing and cash tracking with your CRM. Choose Millisave if you are a mid-market B2B seller that needs help finding and ranking prospects, forecasting a pipeline, and keeping purchasing under control. A 30-minute Millisave demo will show whether it adds value next to your current invoicing tool.

Does Sellsy handle French e-invoicing?
