Custom software for Belgian SMEs

Custom software is an ERP or internal tool built around the way your team works, for SMEs held back by off-the-shelf packages. At Winsol Brebo, one ERP for 3 branches replaces a system from the early 2000s. We build module by module, so your team can keep up.

In short

What

Price
Smaller tools from €1,500 per project. For an ERP we prepare a tailored quote, built up module by module.
Timeline

Winsol Brebo: one instance for 3 branches, a quote calculator with 5 pricing patterns for installation cost and Peppol invoicing via Billit.

01 · What we automate

What we build to measure

Custom software pays off when the way you work is your edge and no package can follow it. This is what we build:

  1. 01

    Custom ERP

    One system for sales, planning, execution and invoicing, with one file per customer and filters per branch or team.

  2. 02

    Quote calculators

    A calculator with your real pricing logic. At Winsol Brebo it works with five pricing patterns for installation cost and purchase rates per piece for subcontractors.

  3. 03

    Customer portals

    Customers follow their own quote, invoices and planning online, without calling your team.

  4. 04

    Integrations with Belgian tools

    Peppol invoicing via Billit, telephony via Telavox, two-way email on the file and messages via WhatsApp Business.

  5. 05

    Internal dashboards

    Overviews per branch, salesperson or project, built from the data already in the system.

  6. 06

    AI inside your own software

    AI triage of email, a website assistant that talks to your ERP or automatic summaries per file.

02 · Process

How we build your software

  1. Week 1

    Analysis of your operation

    We join sales, administration and field work and decide which module delivers the most.

  2. Weeks 2-3

    Building the first module

    We build in Laravel with Filament or on Supabase, with your real data and pricing rules.

  3. Week 4

    Testing and training

    Your team tests the module in daily work. We adjust and train the users.

  4. Then

    Module by module

    Next modules follow at the same pace. The system is monitored 24/7, with a response within the hour to critical incidents.

03 · Case · Winsol Brebo

A custom ERP for three branches

Winsol Brebo installs windows, doors, roller shutters and sun protection from Dilbeek, Sint-Pieters-Leeuw and Aartselaar. The existing system dated from the early 2000s, and 200 to 250 emails arrive every day across 17 to 19 mailboxes.

The new ERP runs on Laravel and Filament: one instance with filters per branch, one owner per file who gets the notifications, a quote calculator with five pricing patterns, purchase rates per piece for subcontractors, Peppol invoicing, caller lookup and two-way email on the file. We build it module by module, so the team can keep up.

  • 3 branches in one instance
  • 5 pricing patterns in the quote calculator
  • 17 to 19 mailboxes
  • 200 to 250 emails a day

When you have to bend your processes to fit the package, with double work, side spreadsheets or workarounds as a result. If a package such as Odoo works well for you, we would rather connect it. Also read AI agents versus SaaS tools.

That depends on the number of modules. We build in phases: your team tests the first module, then the next ones follow. You never go months without results.

Yes. At Winsol Brebo, invoicing runs through Billit over the Peppol network, which has been mandatory since 1 January 2026 for invoices between Belgian businesses.

We migrate the data you need to the new system. During the transition, both systems can run side by side.

Yes. Think of AI triage of incoming email, a website assistant that talks directly to the ERP or summaries of files. See also our AI agents.
