Quotes in a spreadsheet, invoices in another application, customers in an inbox, stock on paper: many Belgian SMEs work with five or six tools that do not talk to each other. An ERP promises to bring everything together. This guide explains what an ERP is, when a small business really needs one, what e-invoicing changes in Belgium, and how to choose without buying an overly complex system.

What is an ERP?

An ERP (Enterprise Resource Planning system) is software that brings a business's management functions into a single database: customers, quotes, invoices, purchasing, stock, scheduling, projects and sometimes accounting. Each piece of information is entered once and used everywhere: a signed quote becomes an invoice, and a sale updates stock.

This single database is what sets it apart from a collection of separate tools. Without it, you copy the customer's name from the quote to the invoice and the invoice total into your tracking spreadsheet, with errors creeping in each time.

ERP or CRM: what's the difference?

A CRM manages customer relationships: contacts, enquiries, appointments, follow-ups and ongoing sales. An ERP covers all business management, including customer relationships, invoicing, stock, purchasing and projects. For an SME, the CRM is often the first module; the ERP comes in when quotes, invoices and stock need to follow.

In practice, the boundary is blurred: many tools sold as CRMs add quotes, and many modular ERPs start with the CRM. Focus instead on scope: what do you want to stop copying manually? For CRM alone, read our CRM guide for SMEs.

Does an SME need an ERP?

An SME needs an ERP when separate tools cost more time than they save: information copied between files, forgotten invoices, inaccurate stock and nobody knowing where a customer stands. As long as a spreadsheet and invoicing software do the job without re-entering data, a full ERP is premature.

The most common signs:

  • You copy data. The same customer is entered in the website form, the quote, the invoice and the tracking spreadsheet.
  • You lose sales. An enquiry received on Friday evening gets a call back on Tuesday, or never.
  • Your stock figures are wrong. A product sold online has already been sold at the counter.
  • You do not know what is profitable. Nobody knows how many hours a project actually took.
  • Your team is growing. Two or three people work with the same customers, each with their own version of the file.

What must an ERP do in Belgium in 2026?

In Belgium, an ERP must first be able to send structured electronic invoices: since 1 January 2026, invoices between VAT-registered businesses established in Belgium must use this format, usually through the Peppol network. It must also handle Belgian VAT rates, French and Dutch, and export data cleanly to your accountant.

The obligation comes from the FPS Finance: structured electronic invoices between businesses have been mandatory since 2026 (efacture.belgium.be, consulted in September 2026). A PDF sent by email is no longer enough between businesses. You must also be able to receive structured invoices from your suppliers: our Peppol guide for Belgium explains the obligation, exceptions and solutions.

Other points to check:

  • Belgian VAT: rates per line (21 %, 12 %, 6 %), mandatory invoice information.
  • Languages: quotes and invoices in French and Dutch if you work in both regions.
  • The link to your accountant: regular exports or a connection to their accounting software.
  • Your data: a full export of your customers and invoices, so you are never locked into one application.

How much does an ERP cost for an SME?

An ERP's price depends on the number of users, modules and setup. Major vendors usually charge per user per month, with setup (configuration, data migration, training) billed separately. For an SME, setup often drives the budget more than the licence.

Three things affect the bill:

  • The pricing model. Per user: costs rise with each new hire. Per module or website: costs follow the features you use, not your team size.
  • Setup. Configuring workflows, importing your customers and products, training the team: an integrator charges consultancy days for this work.
  • Bespoke work. Every custom development costs money when it is built, then again with each software update.

Always ask for the total cost over three years, including setup, for both your current and target number of users.

How do you choose an ERP for a small business?

Choose an ERP based on what you want to stop doing by hand, not the longest feature list. List your workflows (enquiry, quote, invoice, payment, stock), check that the tool covers them without re-entering data and sends invoices through Peppol, then compare the total cost over three years, including setup.

Questions to ask every vendor:

  1. Who handles setup? You, an integrator charging by the day, or the vendor?
  2. How long before you send your first invoice? Weeks of project work or a few days?
  3. Does the price follow your user count or your needs?
  4. Is the tool connected to your website? Website enquiries, orders and appointments should arrive in the tool automatically.
  5. What happens if you leave? Data exports, commitment period, notice period.

A modular ERP connected to your website: how does Eazyclick work?

Eazyclick offers modular management connected to your website: activate only the modules you need (CRM, Peppol quotes and invoices, scheduling, projects, point of sale, shop), set up by a project manager. Every website enquiry, order or appointment goes into the same customer record, without re-entering data. Pricing is per website, not per user.

A few modules and their prices, excl. VAT:

  • CRM Pro: €190 setup fee, then €44/month over 12 months or €35/month over 24 months, for your whole team.
  • Quotes & invoices: from €35/month over 24 months (€44 over 12 months), plus a one-off €190 setup fee; a quote signed online becomes an invoice in one click, sent through Peppol, with a monthly export for your accountant.
  • Team scheduling: €290 setup fee, then €59/month, with unlimited members.
  • Projects & time tracking: from €19/month, to track hours by project and invoice them.
  • Full e-commerce (€1,490 then €99/month) and Point of sale (€290 then €59/month) share a single stock between your online shop and your counter.

These modules can be added to an Eazyclick website (packages from €69/month, see the Packages page), and several also work without a website. Your project manager activates the first module within 48 hours. For an overview, see our all-in-one business management software.

When is a traditional ERP still the best choice?

A traditional ERP remains the best choice if you manufacture (bills of materials, production orders), manage multiple warehouses or complex logistics, want full accounting in the same software, or already have an integrator who has adapted the tool to your processes. Eazyclick does not handle accounting, payroll or production.

In that case, keep your ERP and integrator. Eazyclick can remain your website and enquiry management tool, and your project manager can explore a connection to your accounting software with you, quoted separately. Unsure?
