Sellsy manages your CRM and invoicing. Cleavr recovers your unpaid invoices.
Sellsy is the all-in-one French platform combining CRM, invoicing, accounting and sales management. Adopted by thousands of French SMEs, it centralises quotes, invoices and clients in a single tool. But like most billing tools, Sellsy does not do active collections when a client doesn’t pay.
Cleavr takes over where Sellsy stops.
What the Sellsy x Cleavr Integration Solves
Sellsy users have the advantage of CRM and invoicing in the same tool, but when a Sellsy invoice falls overdue, tracking becomes manual again. Email reminders from Sellsy, unlogged calls, tracking spreadsheets: collections remain manual even with a good management tool.
According to the Intrum 2024 European Payment Report, 86% of European companies experience late payments. For SMEs using Sellsy without a dedicated finance team, every unpaid invoice not chased quickly directly degrades cash flow.
The Cleavr x Sellsy integration automates the entire process.
What the Integration Lets You Do
- Automatically synchronise your Sellsy invoices and clients into Cleavr
- Trigger personalised multichannel reminders the moment a due date is passed
- Leverage Sellsy CRM data to contextualise reminders based on the commercial relationship
- Automatically reconcile collections in Sellsy
- Monitor in real time DSO, aging report and collections efficiency
The Sellsy x Cleavr Advantage for European SMEs

If a client doesn’t respond, Cleavr escalates progressively: through to formal notice and litigation with our partner bailiffs and lawyers, without your team having to intervene.
