AI Invoice Follow-Up Agent: say goodbye to chronic late payments

You know the scene: a pile of unpaid invoices, a client who "will pay next week", follow-up emails sitting in your drafts folder. In France, invoices are paid 13 days late on average. Behind those delays are small business owners losing several hours every week chasing, writing, insisting.

That's exactly why we built our AI agent "Invoice Pilot". It handles the paperwork for you: sorting invoices, drafting follow-ups in your own style, and scheduling reminders automatically. You keep the final say (one click to approve the send) — and above all, you get your time back, and your peace of mind.

Why automate invoice follow-ups in 2025?

1. Fragile cash flow

Every day of delay is cash flow sitting somewhere else. For a small business, that can quickly add up to thousands of euros missing to pay salaries, invest, or simply breathe.

2. Less wasted time

Chasing payments is tedious: finding the invoice, digging up the client's email, rephrasing, softening or hardening the tone... With AI, all of that is prepared in the background. Result: 30% less administrative time.

3. Electronic invoicing is coming

Electronic invoicing between businesses will soon become mandatory in France. Setting up an agent to manage this flow now means getting ahead of it instead of scrambling later.

Our solution: "Invoice Pilot" by Mister Anderson

What the agent actually does

• It reads your documents (Excel, ERP, PDF, and any other format) and extracts the key details without errors.
• It sounds like you: it learns your writing style from your existing emails.
• It follows up progressively: a friendly message first, then firmer, then formal if needed.
• It gives you a clear view: a dashboard of overdue invoices and cash-flow forecasts.
• It archives properly: compliant with French standards, data stored in France.

Up and running in 4 simple steps

1. We connect your tools or import your invoices via CSV.
2. You set your rules: deadlines, tone, penalties.
3. We test it on 10 invoices to fine-tune it.
4. You switch to "autopilot" with a weekly check-in.
