Faits clés
- Late fees are penalties charged when a customer pays an invoice after its due date — designed to incentivize timely payment and compensate for collection effort.
- The most common B2B late-fee structure is 1.5% per month (18% APR) on the unpaid balance, enforceable in most U.S. states with prior contract notice.
- Many jurisdictions cap maximum allowable late fees (often 18-24% APR) and require that the rate be disclosed in the contract or on the invoice before the work began.
- U.S. federal contracts use 'prompt payment interest' rules (per the Prompt Payment Act) that vary based on Treasury rates, currently around 4-6% APR.
- EU late-payment directive (2011/7/EU) sets a statutory minimum of 8 percentage points above the European Central Bank reference rate plus a €40 fixed administrative fee per invoice.
Comment cela se traduit en pratique
A boutique accounting firm bills clients $4,500/month on net-15 terms with a 1.5%/month late-fee clause. When a client pays 32 days late, the firm charges $67.50 (1.5% × $4,500) plus a $25 administrative fee for the past-due processing. The client pays the next month with the late fee included; the policy reduces chronic late-payers within 6 months because clients prioritize the firm's invoices.
Erreurs courantes
- Charging late fees without prior contract or invoice notice — usually unenforceable.
- Setting late-fee rates above state or jurisdiction maximums — risks the entire fee being voided.
- Forgetting to actually charge the late fee on subsequent invoices — signals to chronic late-payers that the policy isn't enforced.
- Charging fixed fees ($25) instead of percentages on small invoices — can make the fee feel disproportionately punitive.
- Applying late fees inconsistently across customers — creates discrimination risk and damages relationships.
Questions fréquentes
What's a typical late-fee rate?
1.5% per month (18% APR) is the most common B2B rate in the U.S. and is enforceable in most states. Some businesses use a flat $25–$50 fee for small invoices and switch to percentage for larger ones.
Can I charge a late fee if I didn't mention it in the contract?
Generally no — late fees require prior notice. If your contract is silent, including the late-fee policy on the invoice itself before the due date can sometimes establish notice for future invoices, but enforcement varies by state.
Are late fees enforceable in court?
Yes if (1) properly disclosed in the contract or invoice, (2) within state usury limits, and (3) reasonable in amount. Excessive fees ('liquidated damages') can be voided as punitive. Most small-claims courts uphold reasonable late-fee provisions.
Should I waive late fees for good clients?
It's a relationship judgment call. Common practice: waive the first late fee with a friendly note, charge subsequent ones. This signals you're reasonable but enforce the policy. Never waive without acknowledgment — it teaches clients to ignore the policy.
What about late-fee enforcement internationally?
Varies widely. The EU has statutory rates (ECB rate + 8% + €40) that apply by default to B2B trade. UK has similar Late Payment of Commercial Debts rules. Asia and Latin America rely more heavily on contract-defined terms. Always verify local enforceability.
