E-Invoicing: How Does It Work in Practice?

Sending, Receiving, Attachments and Accounting Transfer with Hit-Online

As electronic invoicing becomes more widespread in Belgium, many construction companies are wondering:

  • How does it actually work?
  • Is it difficult to set up?
  • What are the real differences compared to sending a PDF via email?

In this article, we explain step by step how to manage an e-invoice in Hit-Online — whether you want to send it, receive it, attach documents, or forward it to your accountant.

Good news: everything is designed to save you time on a daily basis.

E-invoice flow

Creating an E-Invoice in Hit-Online

Five simple ways to create an invoice:

  • Manual invoicing: freely enter an invoice, with or without linking it to a project.
  • From an accepted quote/project: Hit-Online automatically converts your quote or project into an invoice.
  • From a site report form: Work recorded by your team (via smartphone/tablet) auto-generates cost lines, which are imported into the invoice.
  • Based on a progress statement: You can also invoice based on a progress statement.
  • From another invoice: Easily reuse lines from a previous invoice.

Each method helps you save time and ensures data consistency — no more manual copying, everything is ready to go.

Adding Attachments

When editing the invoice, you can attach supporting documents such as:

  • Purchase orders
  • Service details
  • Worksite photos
  • Reports
  • Certificates

These files are sent along with the invoice via the Peppol network, enabling clients to quickly understand and process the invoice.

  • One-click to validate and add to your invoice records

Project Assignment:

  • Click “Assign to projects”
  • Distribute the amount across one or multiple projects
  • Even possible to allocate by line, based on cost type

Result: Your projects stay up-to-date, costs are properly allocated, and no detail is missed.

One-Click Export to Accountant

All validated invoices can be exported via:

  • Structured accounting export: In seconds, Hit-Online generates a file ready for your accountant (compatible with standard accounting software)

Advantage: no input errors — everything is ready for accounting.

Why Are Attachments Strategic?

Attaching documents to e-invoices allows you to:

  • Speed up validation
  • Avoid disputes over unclear charges
  • Improve client trust through transparency

Example: Adding a photo report to a repair invoice helps the client immediately see the work done — accelerating approval.
