Why invoice terms are essential for any business
As an attorney, I help business owners draft invoice general terms and conditions on a daily basis. This may seem like a formality at first glance, but in reality, well-drafted invoice terms are a powerful legal tool. Among other things, they determine your payment terms, your liability, the competent court in case of disputes and your penalty options in case of non-payment by the customer.
And yet these terms and conditions are often underestimated. Many entrepreneurs put general terms and conditions on their invoices without asking themselves whether they are valid and enforceable. Or worse, they copy conditions from a colleague or from an outdated model, with all the legal risks that entails.
What are general terms and conditions on invoice?
Invoice terms are standard provisions you add to your invoice that are designed to strengthen your contractual position. Consider:
- Payment terms (e.g., payment within 30 days)
- late payment interest
- damages or collection costs
- choice of law and choice of forum
- limitation of liability
Such terms and conditions are only enforceable if they are communicated to your customer correctly and in a timely manner. A crucial nuance: the mere fact that the general terms and conditions are on the invoice does not automatically mean that they are legally valid.
Are billing terms binding?
In principle, general terms and conditions must be communicated before or at the latest at the conclusion of the contract. If your customer only sees them on the invoice - which is only sent after delivery or performance - then there is a high risk that the terms and conditions will not be legally enforceable.
Nevertheless, Belgian case law accepts that a tacit acceptance of the invoice can also count as acceptance of the terms and conditions. That means: if your customer receives the invoice and pays it without protest, then the general terms and conditions mentioned can be binding. However, this applies mainly in B2B relationships. With consumers, the bar is much higher.
Consumers vs. businesses: a world of difference
Belgian law, and in particular the Code of Economic Law, protects consumers from unclear, onerous or abusive terms. When working with individuals, many invoice terms that are perfectly valid in a B2B context are simply not enforceable.
👉 This is why it is important to have two sets of conditions:
- One for professional customers (other companies) B2B
- one for consumers (individuals) B2C
This separation increases legal certainty AND shows that you are acting professionally.
How do you draft good billing terms?
1. Clarity and readability
Do not use fine print, incomprehensible language or vague clauses. Unclear clauses will be interpreted to the user's disadvantage, especially with consumers.
2. Reference on the front of your invoice
If you put terms and conditions on the back, make sure you refer to them clearly on the front of the invoice.
3. Publication on your website
Make sure your terms and conditions are easily accessible online. Add a hyperlink on your invoice or your email signature.
4. Distinction between parties
Differentiate between consumers and businesses. Do not refer to clauses that undermine mandatory consumer protection. Those are null and void.
5. Language
Belgium has strict language legislation. Your invoices (and therefore your invoice terms) must be drawn up in the language of the place of business. For international customers: provide translations and be alert to the language used in jurisdiction clauses.
Examples of useful clauses
Want inspiration for your own billing terms? These are clauses that strengthen your legal position:
- Notice and acceptance clause
"The customer declares to have read and agreed to the terms and conditions on the back of this invoice." - Powers clause
"All disputes are subject to the exclusive jurisdiction of the courts of [place name]." - Damages clause
"In case of non-payment within the stipulated period, a lump-sum indemnity of 10%, with a minimum of €150, shall be payable by right and without notice." - Liability limitation
"The company is not liable for indirect or consequential damages"
Have your billing terms professionally drafted
As an attorney, I make sure your terms and conditions are on invoice:
- be legally conclusive
- are tailored to your target audience
- comply with Belgian and European legislation
- taking into account language laws and the law of evidence
Whether you are self-employed, run an SME or are in e-commerce or services - well-drafted billing terms make the difference between certainty and discussion.
