Everything you need to know about B2B debt collection

What is AI-powered debt collection software?

AI-driven debt collection software automates all actions aimed at obtaining payment of an unpaid invoice without resorting to the courts. This collection software combines multi-channel reminders for unpaid invoices (email, SMS, phone calls) with precise tracking of the debtor’s journey, in strict compliance with the Commercial Relations Code and the GDPR.

According to the Payment Delays Observatory, late payments account for a major portion of business failures in France. A well-configured customer reminder software, or AI-powered collection agent, reduces DSO by an average of 15 to 25 days and increases the collection rate from 60% (manual reminders) to 85% (AI-automated reminders).

The 4 steps of amicable debt collection

  • Amicable reminder. Polite email on Day 3, reminder text message on Day 7, AI call on Day 14. Tone tailored to the debtor’s profile and the quality of the business relationship.
  • Formal notice. Registered letter with return receipt in accordance with Article 1344 of the Civil Code, marking the legal starting point for late payment interest.
  • Preparation for litigation. Compilation of the case file (invoices, purchase orders, correspondence) in preparation for a payment order or legal proceedings.
  • Payment plan. A payment schedule negotiated with the debtor in financial difficulty, in compliance with legal deadlines. Often more cost-effective than a lengthy legal dispute.

Why automate reminders for unpaid invoices

4 concrete reasons to automate collections rather than continue manual follow-ups.

  • Protected cash flow. An SME loses an average of 8% of its revenue to uncollected receivables. AI-powered debt collection software reduces this loss to under 2% and clears arrears in less than 90 days through continuous reminders for unpaid invoices.
  • Time saved. Manual follow-ups on unpaid invoices take 3 to 5 hours per week for a manager or accountant. Automating follow-ups with AI-powered customer follow-up software reduces this time to 20 minutes per day of supervision, or 12 to 18 hours per month.
  • GDPR and Consumer Code compliance. Automatic legal notices, individual opt-out options, compliance with time limits, and 5-year archiving. No risk of CNIL complaints or aggressive business practices with this collection software.
  • Collection rate: 85% vs. 62% manually. Collection rate observed for receivables under 90 days: 85% with AI-automated collection vs. 62% manually (source: Agensio pilot studies February–April 2026, n=12 French SMEs with 10–50 employees).

How the AI collection agent works

How to automate reminders for unpaid invoices in 3 steps, configurable in 10 minutes from your collection software dashboard.

  • 1. Accounting integration. Connect your invoicing software (Pennylane, Sage, Cegid, Stripe, QuickBooks France) or import a CSV file. The AI collection agent automatically retrieves overdue invoices, balances, and payment history for each customer.
  • 2. Automatic 24/7 monitoring. The AI agent in this software scans for overdue invoices every 4 hours. As soon as an invoice becomes overdue, the collection scenario for the unpaid invoice is triggered based on the debtor’s profile (good payer, chronic late payer, dispute, high risk). Tone, frequency, and channel are adapted by artificial intelligence.
  • 3. Multi-channel email, SMS, and phone calls. Polite email on Day 3, firm email on Day 7, SMS on Day 14, AI-powered French-voice call on Day 21, formal notice on Day 30: automate reminders from start to finish. Each message includes a Stripe and GoCardless link for one-click payment. You can take over at any time.

Frequently Asked Questions

Everything you want to know about this AI agent.

Is automated debt collection legal in France?

Yes, it is perfectly legal as long as the debtor is informed about the processing of their data (GDPR notice in every email), the contact times are reasonable, and the messages are neither threatening nor harassing. Our agent complies with these requirements by default.

How long before I see the first payments?

The first payments arrive within 7 to 14 days of activation. The agent processes your initial backlog of unpaid bills in less than 24 hours. Full ROI measurable within 60 to 90 days.

What happens if the debtor doesn’t pay?

After 4 unresponsive friendly reminders, the agent escalates to a formal demand letter with return receipt requested. If there is no response within 8 days, you are notified to decide: payment order, bailiff, or writing off the debt.

Will my clients know it’s AI?

No, the reminders are signed with your name and look exactly like a human-written email. The AI customizes the tone based on the customer’s history. The GDPR notice does not explicitly mention AI, only automated processing.

How can I automate reminders for unpaid invoices?

To automate reminders for unpaid invoices, connect your invoicing software to an AI-powered debt collection software like Agensio. The AI collection agent detects each unpaid invoice as soon as it becomes overdue and triggers a multi-channel scenario (email, SMS, AI call, formal notice). You retain control to stop, adjust, or add a payment plan.

What software is best for debt collection?

The right debt collection software for a French SME combines accounting integration, automatic multi-channel reminders for unpaid invoices, AI-powered calls in French, formal notices compliant with Article 1344, and DSO reporting. Agensio meets all these criteria at €82.50/month (excl. tax), whereas Sage Recouvrement, Eloficash, or Dunforce start at €200–500/month.

Customer reminder software: how to choose?

When choosing customer reminder software, check for 5 criteria: native integration with your accounting system, the ability to automate multi-channel reminders (email, SMS, AI calls), compliance with GDPR and the Consumer Code, transparent pricing (subscription + performance-based commission), and the quality of French-language support. An AI debt collection software like Agensio checks all 5 boxes.

Does the AI debt collection agent replace a bailiff?

No. The AI debt collection agent handles the amicable phase (Day 3 to Day 60): it automates reminders for unpaid invoices via email, SMS, and AI calls, then sends the formal notice of default. If the debtor still does not pay, you escalate the matter to a bailiff for service of process and enforcement. AI-powered debt collection recovers 80 to 85% of debts before a bailiff is needed.

How does integration with my accounting software work?

Less than 10 minutes: OAuth connection to your invoicing software (Stripe, Pennylane, Sage, Cegid, QuickBooks), automatic import, configuration of business rules, activation. No technical expertise required.

How much will I pay in commission?

Declining commission: 15% (Starter), 10% (Growth), 6% (Suite). Calculated only on the amount actually recovered. Compare this to traditional collection agencies (20–30%) or a lawyer (flat fee + 15–20%).
