Late payments and unpaid invoices are a growing challenge for businesses across France and Europe. More and more companies are looking to automate their collections process to protect their cash flow without spending hours chasing payments. Two solutions stand out in the French market: Billabex and Clearnox. These two tools take radically different approaches to collections automation.
On one side, Billabex leverages generative AI to create an autonomous agent that handles the entire reminder cycle with no human input required. On the other, Clearnox offers a collaborative SaaS credit management platform designed for teams that want to stay in control while benefiting from powerful automation.
Which one should you choose? The answer depends on your profile: company size, available resources, desired level of automation and budget. This article provides a detailed, objective comparison of both solutions.

Clearnox Overview
Clearnox is a French accounts receivable and credit management platform launched in 2017. Designed to support finance teams juggling client reminders, payment tracking and reporting, the platform has positioned itself as a collaborative tool accessible to businesses ranging from small companies to mid-market enterprises.
A team-centric collaborative platform
Clearnox’s philosophy is built around collaboration. The solution is designed for teams working together on accounts receivable: each user can see the full history of exchanges with a debtor, leave comments, assign tasks and track progress in real time. This collaborative dimension sets it apart from purely automated tools.
Key features
- Customizable reminder workflows: define collection scenarios tailored to each client segment — key accounts, SMEs, regular customers — with send options via email, SMS or postal letter.
- Advanced dashboards and reporting: real-time visibility on collections, DSO (Days Sales Outstanding), payment delays and client risk profiles. Data is refreshed automatically.
- Bad payer scoring: an automatic scoring module assesses the risk of late payment for each client, helping prioritize actions.
- Multi-currency support: Clearnox handles more than ten currencies with daily exchange rate updates — a real asset for export-oriented businesses.
- Online payment module: clients can pay directly from the reminder they receive, reducing friction and accelerating cash collection.
- Automatic late payment penalty calculation: the platform automatically calculates and incorporates legal penalties into communications.
Who Clearnox targets
Clearnox primarily targets SMEs and mid-market companies that have an accounting or finance team. It is especially well-suited to businesses with a significant client portfolio looking to structure their collections process with a professional tool.
Integrations
Clearnox integrates with the leading ERP and accounting platforms: Sage, Cegid, Microsoft Dynamics, SAP, Oracle. These native connectors automatically synchronize invoices and payments from your existing systems, eliminating manual data entry.
Pricing
Clearnox offers three subscription tiers:
- Start: from €149/month, for small companies with revenue under €2M
- Premium: around €299/month, for SMEs with higher volumes
- Gold: from €549/month, for mid-market businesses with advanced needs
Pricing varies by number of users, invoice volume and active features. Most companies that use Clearnox with a dedicated team land on Premium or Gold plans.
Billabex Overview
Billabex is a French solution born from the convergence of generative AI and accounts receivable management. Where traditional software automates human-configured workflows, Billabex creates an autonomous AI agent that manages the entire reminder cycle without you ever having to step in.
The AI agent: the core value proposition
Billabex’s founding concept is simple: you connect your invoices, set a few preferences, and the AI handles the rest. The agent analyzes each situation — invoice age, client’s payment history, amount at stake, commercial relationship — and writes personalized, context-aware messages in the right tone.
No static templates to fill in, no workflows to configure step by step: the AI understands the context and acts.
Key features
- Autonomous multichannel AI reminders: the agent sends emails, SMS and formal demand letters, adapting the message to each situation. Zero clicks on your end.
- Contextual personalization: the AI adapts its tone (friendly, professional, firm) based on the debtor’s profile, overdue duration and relationship history.
- Automatic escalation: if a reminder goes unanswered, the agent gradually increases pressure and can trigger a formal demand letter.
- Simplified dashboard: real-time view of your receivables, AI actions and payments received.
- Ultra-fast onboarding: connect your billing software and the AI takes over in under an hour.
- Native connectors: Billabex connects to Pennylane, Sage, Sellsy and others via an open API.
Who Billabex targets
Billabex is built for SMEs, freelancers, consultants and accounting firms that want to recover unpaid invoices without spending time on it. It is particularly effective for organizations without a dedicated credit team, looking for total automation with no complex setup or training required.
Pricing
Billabex starts at €49/month, with all AI features included. Plans scale with invoice volume. It is one of the most accessible solutions on the market for this level of automation.
Detailed Comparison
Reminder automation
This is where the two solutions differ most dramatically.
Billabex delivers total, autonomous automation. Once connected, the AI agent sends reminders, adapts messages, escalates cases and tracks responses — all without any intervention from you.
Clearnox offers powerful, configurable automation that still requires human oversight. You define the reminder scenarios, send rules and workflows. The tool executes them faithfully, but your team remains in control. Unexpected situations or complex client behavior still require a human touch.
Artificial intelligence
Billabex is an AI-native solution. Generative AI is at its core: it drafts each message based on context, learns from past behaviors and continuously adapts its approach.
Clearnox includes intelligent features — client scoring, prioritization rules, conditional automation — but does not rely on generative AI. Messages are based on templates that you write in advance.
Reminder personalization
Billabex automatically personalizes every message based on client behavior and profile. Personalization is dynamic and requires no manual input.
Clearnox enables advanced personalization through its templates and scenarios, but this personalization is manual: your team writes the templates and defines the send conditions.
Integrations
Billabex offers an open API and native connectors for the main billing and accounting tools used by French SMEs: Pennylane, Sage, Sellsy. New connectors are regularly added.
Clearnox integrates primarily with enterprise ERP and accounting systems: SAP, Oracle, Sage, Cegid, Microsoft Dynamics. Integrations are robust and designed for more complex IT environments.
Pricing
| Solution | Entry price | Typical SME plan |
|---|---|---|
| Billabex | €49/month | €49–€199/month |
| Clearnox | €149/month | €299–€549/month |
Ease of use
Billabex is designed to be operational in under an hour. No training required, no complex setup: connect your invoices and the AI takes over.
Clearnox requires a longer onboarding period, particularly to configure reminder scenarios, integrate data from your ERP and train your team.
Customer support
Both solutions offer quality support. Clearnox provides a more structured onboarding experience with dedicated implementation support. Billabex offers responsive email and chat support with thorough French-language documentation.
