Legal Basis

The debtor is in default when:

• The payment deadline has passed
• The invoice was due
• A reminder has been received (except with calendar-specific due dates)

Important: Without an agreed payment term, 30 days after invoice receipt = automatic default.

Default Damages Entitle You To:

• Late payment interest: Variable based on jurisdiction
• Collection fees: Reasonable amounts ($2-5 per notice)
• Fixed costs: Administrative costs (B2B only)

Calculating Late Interest

Formula:

Late Interest = Invoice Amount × Interest Rate × (Days Overdue / 365)

Example:

• Invoice Amount: $1,000
• Days Overdue: 30 days
• Interest Rate: 9% (B2B typical)

$1,000 × 9% × (30 / 365) = $7.40 Late Interest

Tip: Check your local jurisdiction for applicable interest rates. They vary by country and may change periodically.

---

Collection Fees: What's Allowed?

Principle:

Collection costs must be reasonable. Courts typically accept:

• $2.50 per notice (postage + effort)
• Maximum $5 for elaborate notices
• Fixed fees only in B2B transactions

Common Collection Mistakes

❌ Too Emotional

Bad: "It's outrageous that you haven't paid!" Better: "Unfortunately, payment has not yet been received."

❌ Threats Without Legal Basis

Bad: "We will publicly shame you!" Better: "We will transfer the debt to a collection agency."

❌ Unrealistic Deadlines

Bad: "Pay immediately!" (no deadline) Better: "Please transfer by January 15, 2025."

❌ Missing Information

Every notice needs:

• Invoice number and date
• Original amount
• Collection fees (if charged)
• Late interest (from 2nd notice)
• Bank details
