Can You Charge Interest on Unpaid Service Invoices Without a Contract?
Imagine sending out an invoice for your consulting services, only to have the client drag their feet on payment. Frustrated, you consider adding interest to nudge them along. But can you legally charge interest on an unpaid invoice for services rendered when there is no written agreement to that effect? This is a common dilemma for freelancers, contractors, and service-based businesses.
In this post, we'll break down the legal landscape, primarily drawing from Malaysian case law, while touching on insights from other jurisdictions. Note: This is general information and not specific legal advice. Consult a qualified lawyer for your situation.
The Short Answer: Generally No, Without Proof or Agreement
Interest cannot be automatically charged on an unpaid invoice for services rendered solely based on customary market practice in the absence of a written agreement. This differs sharply from sales of goods, where such interest may be imposed via established custom evidenced in invoices or statements. For services, including construction work, any claim for interest requires specific proof of a similar custom through industry experts or must be pursued as for or via discretionary award under .
Key points to remember:- Default interest on unpaid goods sales is enforceable via custom without a contract, but this does not extend to services without proof.- Services claims for interest are restricted to traditional breach remedies or statutory discretion.- Invoices or statements alone do not suffice to impose interest on services absent further evidence or agreement.
: Goods vs. Services Distinction
The law draws a clear line between goods and services. For goods, courts have recognized that default interest stipulated in the invoice or monthly statement of accounts may be imposed and enforced on unpaid sale of goods transactions despite the absence of contractual provision because it is customary being a well established and accepted market practice.
However, This practice on imposition of interest cannot however be so assumed on unpaid construction work and services rendered without proof of such similar custom subsisting through construction industry experts.
This establishes that is not presumed for services; explicit evidence is mandatory. In contrast, cases involving goods often uphold invoice-based interest due to entrenched trade practices.

Alternative Remedies for Interest on Unpaid Services
Where custom is unproven, interest on unpaid services is not barred but channeled through standard remedies: Consequently, the claim for interest on unpaid construction work and services rendered is limited to proof by way of for in the usual way or discretionary interest pursuant to s 11 of the .
This limits recovery to judicial discretion or proven damages, preventing unilateral imposition via invoice alone. Courts may award under statutory provisions, but you can't preemptively charge it on your invoice without basis.

Exceptions and Limitations
While the rule is strict, exceptions exist:- Proven Custom: If industry experts substantiate a custom for services akin to goods, interest could apply despite no written agreement, though no document evidences such proof succeeding.
- Statutory Discretion: Section 11 Civil Law Act allows courts to award interest post-judgment, but this is not preemptive charging on invoices.- Goods Sales Only: The custom exception is confined to sale of goods transactions, explicitly excluding services.
- No unilateral interest on services invoices without bases; other references assume contractual support.
Limitations from other sources highlight evidence needs: Non-issuance of invoices meant no services rendered, barring claims.

Practical Recommendations for Service Providers
To protect your cash flow:- Avoid self-imposed interest on unpaid services invoices without agreement to prevent enforceability challenges; instead, sue for principal plus proven damages interest or seek s11 discretion.- Gather expert evidence of industry custom if claiming customary rates.- Ensure future invoices reference any interest terms explicitly to invoke contractual enforceability, as seen in upheld cases.
- Legal professionals should frame claims distinguishing goods/services and prioritize breach/damages arguments per prevailing authority.
Proactively include interest clauses in proposals or terms of service. Track payments diligently and send polite reminders before escalating.

- Rely on breach damages or statutory discretion for recovery.
