Payment Terms Guide

Term	Meaning	Best For
Due on receipt	Pay immediately	Small one-time jobs
Net 15	Pay within 15 days	Ongoing freelance work
Net 30	Pay within 30 days	Corporate clients (industry standard)
Net 60	Pay within 60 days	Large enterprises (avoid if possible)
50% upfront	Half before, half after	Large projects ($5,000+)

Pro tip: Always use Net 15 or shorter for new clients. You can extend to Net 30 after they've proven reliable. Never accept Net 60+ unless the project value justifies it.

Tracking Payments

Sending an invoice is only half the job. You need to track what's been paid, what's outstanding, and what's overdue.

Mark invoices as paid the moment payment clears — don't wait.
Follow up on Day 1 past due. A polite "Just checking in on invoice #X" works better than waiting weeks.
Charge late fees. Include late fee terms on every invoice (1.5% per month is standard). You don't have to enforce it every time, but having it on the invoice gives you leverage.
Export monthly reports. Know your outstanding receivables at all times.

Invoice Records for Tax Time

The IRS requires you to keep financial records for at least 3 years. Good invoicing practices make tax season painless:

Export all invoices to CSV at year-end. One file with every invoice, amount, date, and payment status.
Separate business and personal. Use a dedicated business bank account.
Track by quarter. Estimated taxes are due quarterly — know your revenue each quarter.
Save PDF copies. Keep a digital copy of every invoice sent, organized by year and client.

FAQ

Do I need an LLC to send invoices?

No. Sole proprietors can invoice under their personal name. An LLC provides liability protection but isn't required for invoicing. Use your legal name or DBA (doing business as) name.

Should I charge sales tax on services?

It depends on your state and the type of service. Most states don't tax services, but some (like Texas, Hawaii, and New Mexico) do. Check your state's rules or consult a tax professional.

What if a client doesn't pay?

Send 3 follow-up reminders (Day 1, Day 7, Day 14 past due). If still unpaid after 30 days, send a formal demand letter. After 90 days, consider a collection agency or small claims court for amounts over $1,000.
