e-invoice.be Advisory

Practical Peppol
& e-invoicing advisory.

We run the access point, we process the invoices, we built the tooling. Vendor-neutral advisory for finance and IT leaders preparing for Peppol, EU ViDA, and country-specific e-invoicing mandates worldwide.

Why companies bring us in

E-invoicing looks simple on paper. The work happens between the mandate, the ERP, and the supplier base.

  1. 01

    Mandate deadlines are closing in

    Belgium went live in January 2026. France and Germany are rolling out staged mandates. EU ViDA targets 2030. Your team has to plan, scope, and execute while running the business.

  2. 02

    ERP integration is harder than the slide deck

    SAP, Oracle, Dynamics, NetSuite, Odoo. Every landscape has a unique chart of accounts, custom fields, and edge cases. The vendor docs cover the happy path. Your invoices live in the long tail.

  3. 03

    UBL and XML output rarely passes on the first try

    EN16931, Peppol BIS 3.0, country-specific extensions like XRechnung and Factur-X. Schematron rules reject invoices for reasons that look minor and block payment for reasons that are not.

  4. 04

    Your customers and suppliers are not ready

    Going live alone does not move the needle. You need to know which counterparties are reachable on Peppol today, which need onboarding, and which still require legacy formats during the transition.

Six advisory packages

Productised engagements with fixed scope. No open-ended hourly billing.

How an advisory engagement works

From the first call to a working system. Predictable, written, and accountable.

  1. 1

    Discovery call

    A 30-minute conversation with a co-founder or a senior e-invoicing expert. We listen, we ask, and we tell you whether we are the right fit. No sales theatre.

  2. 2

    Tailored proposal in 48 hours

    We send a written proposal with scope, deliverables, timeline, and pricing. Fixed-scope packages have a fixed price. Retainers have a clear monthly rate.

  3. 3

    Engagement starts

    We work directly with your finance, tax, and IT leads. Weekly checkpoints, written status updates, and a single point of contact who actually does the work.

  4. 4

    Go-live and beyond

    Most engagements end at a clean go-live. Some continue as Automation or Compliance & Tax retainers. There is no platform lock-in either way.

Frequently asked questions

Quick answers about scope, pricing, country coverage, and how we work.

How is Advisory different from your platform?
The platform is the Peppol Access Point and the SaaS that thousands of customers use day-to-day. Advisory is the human practice that helps mid-market and enterprise teams plan, scope, and execute their e-invoicing transition. Advisory is vendor-neutral. You do not have to commit to the e-invoice.be platform to engage us.
Why pick e-invoice.be Advisory over a Big 4 firm?
We operate a certified Peppol Access Point and process real invoices every day. We built the validators, the format converters, and the API. You work directly with the people who do the work, not a leverage pyramid. Pricing is transparent and proposals land within 48 hours.
Which countries do you support?
We engage on the global Peppol network and the EU ViDA roadmap. We have particularly deep experience with the Belgian, French, German, and Dutch mandates, and regularly work on cross-border setups well beyond the EU. Mention your country mix on the discovery call.
Do I have to switch to your platform?
No. Advisory engagements are vendor-neutral. Many clients keep their existing access point or ERP setup. In practice, some choose to migrate to the e-invoice.be platform after the engagement, but it is never a precondition.
How is pricing handled?
Three of the six packages are fixed scope at a fixed price: Readiness Assessment, UBL/XML Validation, and Implementation. Implementation has a day-rate overflow for out-of-scope work. The other three are retainers at a clear monthly rate: Automation, Compliance & Tax Advisory, and Operations Support. We tailor the proposal to your scope and send it within 48 hours of the discovery call.
Who will I be working with?
Discovery calls are with a co-founder or a senior e-invoicing expert. Engagements are delivered by senior practitioners. There is a single point of contact who actually does the work and who you can reach directly.
How long does an engagement take?
A Readiness Assessment is typically 2 to 4 weeks. A UBL/XML Validation engagement is typically 2 to 6 weeks depending on complexity. Implementation timelines depend on the ERP landscape and country scope, often in the 2 to 6 month range. Retainers run for as long as they keep adding value.
