Since 1 September 2026, French businesses have been rebuilding their invoice flows to meet the e-invoicing reform. Germany and the UK are next, each with its own timeline and model. For companies operating across these markets, compliance is now a multi-country project. But a compliant e-invoice doesn't guarantee that the bank details on it belong to your supplier.

Fraudsters know this. Fake supplier change requests and altered bank details work because the documents look legitimate. A major process change, with busy teams and new workflows, gives them the opening they need. A single fraudulent transfer can cost more than the whole e-invoicing project, and that money is rarely recovered.

In this webinar, Comarch and Sis ID, an Eftsure company, show how to close that gap without launching a second project.

Agenda

✔️France: lessons learnt from the mandate

What the first weeks of the mandate have looked like in practice: working with Plateformes Agréées, the supplier directory, data quality issues and invoice rejections. We’ll look at what companies underestimated, and at how fraudsters are using the reform as cover, from fake calls about Chorus Pro or the platforms to bank details slipped in during supplier re-onboarding.

✔️Germany and the UK: what to expect

Germany is introducing its issuing obligation in phases, with XRechnung, ZUGFeRD and Peppol at the center of the picture. The UK is preparing its own mandate. We’ll cover the timelines and the expected models, and explain why re-collecting supplier data for each new mandate is also the right moment to verify bank details. For international groups, the fraud risk applies in every country at the same time.

✔️Securing the payment behind the e-invoice

How fake-supplier and bank-detail-change fraud works, and how to stop it. Sis ID explains real-time bank account ownership verification in more than 200 countries, the financial guarantee that comes with it, and where these checks fit in a Comarch-based process: supplier onboarding, bank detail changes and the moment before payment.
