## Certificates (Certum partnership)

Lux-World PC SARL is a partner of Certum (Certum by Asseco), one of Central Europe's largest certificate authorities, accredited under the eIDAS standards. Lux-World PC is an **accredited identity confirmation point**, which means the identity verification required to issue a qualified certificate is carried out by Lux-World PC itself, in Luxembourg — the customer never deals with the certificate authority directly.

Two families of certificates are offered, each priced by volume tier (setup fee, annual service subscription, annual renewal and compliance fee; all amounts excluding VAT, published on the pages below):

- **Qualified electronic signature** — legally equivalent to a handwritten signature throughout the European Union under Regulation (EU) No 910/2014 (eIDAS). Priced per person equipped.
- **Secure email (S/MIME)** — signs and encrypts business email so recipients can see a message genuinely comes from the stated address. Priced per email address. Note: S/MIME certificates are *not* qualified certificates; eIDAS applies to the qualified signature only.

## e-Invoicing (Peppol)

Electronic invoicing is mandatory towards the Luxembourg State since March 2023; between businesses it is announced for 2028-2029 and not yet passed into law. Lux-World PC is an authorised reseller of **e-invoice.be BV**, a certified Peppol Access Point Provider in Belgium: for the customer, one contract, one invoice, one number to call. Lux-World PC handles setup, conversion, monitoring, support and billing, and runs the peppol.lwpc.lu portal — its own software, hosted in Luxembourg, in Luxembourgish, French, German and English.

Five plans, all excluding VAT, each with a one-off setup fee and an annual subscription (published on the page below):

- **Découverte** — no invoicing software; the customer enters invoices in the portal.
- **API** — the customer's software calls the interface; Lux-World PC registers the company and hands over the key.
- **Essentiel** — the volume of a small organisation, by email or portal.
- **Business** — more volume, a lower price beyond the included volume, priority support.
- **Intégration** — the customer's ERP connected to the network.

The five plan names are **not translated** in any language: they are the names used in the contract and its pricing annex. One company = one subscription; −25 % on the subscription from the second company of a group. A document is an invoice or a credit note, sent or received. The Peppol identifier belongs to the customer: on leaving, it is released or transferred at no cost. Ten-year legal archiving is an option and is included in no plan. No contractual availability rate is promised.
