Cash flow issues represent one of the biggest threats facing small-to-medium enterprises (SMEs) globally. With late payments becoming the new norm, late fees and interest on overdue balances provide great motivation for prompt payment.

But depending on where your business is based, different restrictions may apply. In this article, we’ll offer some guidance on how much interest you can charge in different parts of the world and how this can be translated into your payment terms.  

When determining how much interest you can charge on overdue invoices, keep in mind that the figure you settle on should be fair and reasonable.

Late fees are there to serve as a deterrent and shouldn’t be a source of profit. Remember too that while your country may allow you to charge interest, your customer must have agreed to your payment terms for it to be enforceable.

Can I charge late fees if my customer is in a different country?

Yes, but the applicable law depends on your contract terms. Most international contracts specify which country's laws govern the agreement. If not specified, it's typically the supplier's country law that applies. Always include a "governing law" clause in your international contracts to avoid confusion.

What's the difference between statutory and contractual late fees?

Statutory late fees are set by law and apply automatically (common in EU countries). Contractual late fees are negotiated between parties and must be agreed in writing (common in US, Canada, Australia). Even in countries with statutory rates, you can often agree to different rates by contract, subject to reasonableness limits.

Do I need to send a reminder before charging late fees?

In most jurisdictions, no reminder is legally required if your contract clearly states late fees apply automatically. However, best practice is to send at least one reminder before applying fees. Automated reminders through Paidnice can handle this professionally while maintaining good customer relationships.

Can I charge compound interest on late payments?

This varies by country and contract terms:

• Allowed with clear terms: US, Canada, Australia (if specified in contract).
• Generally simple interest only: Most EU countries.
• Prohibited or restricted: Some jurisdictions limit compounding.

Always specify whether interest is simple or compound in your payment terms.

What if my country doesn't have a statutory late fee rate?

If there's no statutory rate (like in Australia, New Zealand, or most US states), you must:

1. Include late fee terms in your contract/invoice.
2. Ensure fees are reasonable (typically 1-2% monthly).
3. Apply fees consistently to all customers.
4. Consider industry standards in your sector

Without written agreement, you typically cannot charge any late fees.

Are there any industries where late fees are restricted?

Yes, several industries face special restrictions:

• Consumer lending: Subject to strict usury laws in most countries.
• Healthcare: Many jurisdictions limit medical debt interest.
• Residential rentals: Often capped at lower rates than commercial.
• Government contracts: May have specific prompt payment rules.

Always check industry-specific regulations in your sector.

How do I enforce late fees internationally?

International enforcement can be challenging but these steps help:

1. Clear contracts: Include specific late fee terms and governing law clauses.
2. Professional invoicing: Use automated AR tools for consistent application.
3. Local collection partners: Work with agencies familiar with the debtor's jurisdiction.
4. Consider arbitration: Include arbitration clauses for faster resolution than courts.

What's the best late fee structure for my business?

The optimal structure depends on your business model:

• High-value B2B invoices: Use percentage-based interest (statutory rate or 1.5-2% monthly).
• Small invoices (<$500): Fixed fees work better ($25-75 depending on amount)
• Mixed client base: Create different fee structures for different customer segments.
• International sales: Consider using the most restrictive rate across all jurisdictions for simplicity.
