Late Fee Calculator for Small Businesses

For small businesses, late payments aren't just an inconvenience — they're an existential threat. 82% of small business failures involve cash flow problems, and late-paying customers are a primary driver. Even a single 60-day delay on a large invoice can cascade into missed payroll.

Late Payment Tips for Small Businesses

✓Clearly print late fee terms on every invoice — "1.5% monthly interest on balances over 30 days"
✓Set a threshold (e.g., 60 days) where you escalate to a collections process
✓Offer multiple payment methods (ACH, credit card, wire) to remove friction
✓Run credit checks on new B2B customers before extending net terms
✓Consider invoice factoring for chronically slow-paying clients (sell the invoice at a discount for immediate cash)
