Net 15: Payment due in 15 days
Due on Receipt: Immediate payment expected
2/10 Net 30: 2% discount if paid within 10 days

3. Be Specific with Descriptions

❌ Bad: "Services rendered" ✅ Good: "Website design - 5 pages including homepage, about, services, blog, contact"

4. Send Invoices Promptly

Send immediately upon completion
For ongoing work, invoice monthly
Set recurring reminders

5. Include Late Payment Terms

"Accounts not paid within 30 days are subject to a 1.5% monthly interest charge"

Common Invoice Mistakes to Avoid

❌ Mistake #1: No Invoice Number

Without unique numbers, tracking becomes impossible.

❌ Mistake #2: Vague Descriptions

"Consulting services" doesn't tell the client what they're paying for.

❌ Mistake #3: Missing Payment Instructions

Always specify HOW to pay you.

❌ Mistake #4: No Due Date

Without a deadline, payment gets postponed indefinitely.

❌ Mistake #5: Math Errors

Double-check calculations or use automated tools.
