Why Invoicing Matters More Than You Think
Most freelancers spend hours perfecting their work — then send a sloppy invoice as an afterthought. That's a mistake. Your invoice is the last thing your client sees before paying you. A professional invoice signals that you're a professional. A messy one signals the opposite.
Here's everything you need to know to invoice like you've been doing this for years.
What Every Invoice Must Include
A legally valid invoice (and one that actually gets paid) needs these elements:
- Your business name and contact info — name, email, address, phone
- Client's name and address — who you're billing
- Invoice number — unique identifier for your records and theirs
- Invoice date — when the invoice was issued
- Due date — when payment is expected
- Line items — description, quantity, rate, and amount for each service
- Subtotal, taxes, and total — clear breakdown of what they owe
Setting Payment Terms That Work
Your payment terms determine how quickly you get paid. Here's what the common ones actually mean:
- Net 7 — payment due 7 days from invoice date. Best for small projects.
- Net 15 — payment due 15 days. Good middle ground.
- Net 30 — payment due 30 days. Standard for larger companies.
- Due on receipt — payment expected immediately. Works when you have leverage.
New to freelancing? Start with Net 7 or Net 14. Don't let clients push you to Net 60 unless it's a large retainer and they've earned that trust.
How to Number Your Invoices
Use a consistent numbering system. The simplest: INV-001, INV-002, etc. If you work with multiple clients, consider prefixes: ACME-001 for Acme Corp, WIDGET-001 for Widget Co.
Never reuse invoice numbers. Ever. It creates accounting headaches for you and your clients.
What Currency to Invoice In
Invoice in your local currency whenever possible. It puts the exchange rate risk on your client, not you. If a client insists on their currency, add 5–10% to your rate to account for exchange fluctuations.
Following Up on Unpaid Invoices
Invoices go unpaid for two reasons: they were forgotten, or they're being ignored. Most are forgotten.
- Day 1 after due date: Send a friendly reminder. "Hi [Name], just checking in — invoice #INV-001 for $X was due yesterday."
- Day 7: Follow up again. Less friendly, more direct.
- Day 14: Phone call or escalate.
Add a late fee clause to your contracts (e.g., 1.5% per month on overdue balances). You may never enforce it, but it changes the psychology of slow-paying clients.
