I freelanced for three years before I made a proper invoice. The first year, I sent clients a text message saying "hey can you send me $800 for the website." The second year, I upgraded to a Google Doc that vaguely resembled an invoice. The third year, a client asked for a "proper invoice with a number and tax breakdown" and I panicked.
Most invoice tools want $10-20/month. Wave is free but makes you create an account and then tries to sell you payroll services. FreshBooks gives you 5 free invoices and then locks you out. For someone who sends 2-3 invoices a month, paying for invoicing software feels ridiculous.
This tool does the job. Fill in the fields, add your line items, hit print, save as PDF. No account. No monthly fee. Your data isn't stored anywhere — close the tab and it's gone.
What Goes on a Proper Invoice?
If you've never sent an invoice before, here's what should be on it. Not because it looks nice — because clients, accountants, and sometimes tax authorities expect this stuff.
- Your name or business name. Obvious, but I've seen invoices where the sender forgot to put their own name.
- Client's name or company. "Bill To" section. Their accountant needs to know who the invoice is addressed to.
- Invoice number. Sequential. INV-001, INV-002, etc. This matters for bookkeeping. If you don't number your invoices, you look unprofessional and it creates a headache during tax season.
- Date and due date. When you sent it and when you expect payment. "Net 30" (due in 30 days) is standard. Some freelancers do Net 15 or even due on receipt.
- Line items. What you did, how many units, what rate. Be specific. "Web development services" is okay. "Homepage redesign — 20 hours @ $75/hr" is better. Specific line items reduce questions and payment delays.
- Tax if applicable. If you charge sales tax or VAT, include it. This tool calculates it for you.
- Total amount. Big, clear, impossible to miss.
- Payment instructions. Bank details, PayPal email, Wise link — whatever you accept. Put it in the notes field. Make it easy for them to pay you.
Freelancer Invoicing Mistakes That Cost You Money
I made most of these. Learn from my pain.
Not Invoicing Fast Enough
You finish a project on Friday. You tell yourself you'll send the invoice Monday. Monday you're busy. Two weeks pass. The client has moved on to other things and your invoice is now low priority in their queue. Invoice the same day you deliver. Same hour if possible. The closer the invoice is to the delivery, the faster you get paid.
Vague Line Items
"Consulting services — $3,000." What does that mean? The client's bookkeeper has no context. Their manager who approves payments has no context. Vague invoices get stuck in approval limbo. Instead: "Brand strategy workshop — 2 sessions × $1,500" or "SEO audit report — 1 × $3,000." Specific enough that anyone at the company can understand what they're paying for.
No Due Date
An invoice without a due date is a suggestion. "Pay whenever you feel like it" is what the client reads. Always include a due date. Net 30 is the safest default — it's what most businesses expect. If you have a good relationship with the client and need faster payment, Net 15 or "Due on receipt" are fine too. Just make it explicit.
Not Including Payment Details
The invoice says "$2,500 due" but doesn't say how to pay. The client has to email you asking for your bank details. That's another back-and-forth, another delay. Put your payment information right on the invoice: bank account + routing number, PayPal email, Wise link, Stripe payment link — whatever you use.
Not Numbering Invoices
"invoice_final_v2.pdf" is not an invoice number. Use sequential numbers: INV-001, INV-002, etc. Or date-based: INV-2025-001. Your accountant will thank you during tax season. The IRS (or your local tax authority) definitely expects numbered invoices if you're ever audited.
How to Save Your Invoice as PDF
Click "Print / Save as PDF." When the print dialog opens, change the destination from your printer to "Save as PDF" (or "Microsoft Print to PDF" on Windows). Hit save. You now have a clean, professional PDF you can email to clients.
This works in every modern browser — Chrome, Firefox, Edge, Safari. The output looks exactly like the preview. No watermarks, no "generated by XYZ tool" branding at the bottom.
When to Use This vs. Invoicing Software
Be honest about where you are:
- Sending 1-5 invoices per month, solo freelancer? This tool is all you need. Generate, save as PDF, email it. Done.
- Sending 10+ invoices/month, tracking payments, need recurring invoices? You probably want software like Wave (free), Zoho Invoice (free tier), or FreshBooks ($17/month). They track what's paid vs. outstanding and send reminders automatically.
- Running a business with employees and complex accounting? You need QuickBooks, Xero, or similar. That's a different league.
This tool sits in the sweet spot for freelancers and small operators who don't want to pay for software and don't need payment tracking. You make the invoice, you send it, you follow up manually. For most people starting out, that's enough.
Currencies We Support
The tool supports 13 currencies: US Dollar ($), Euro (€), British Pound (£), Swiss Franc (CHF), Canadian Dollar (CA$), Australian Dollar (A$), Indian Rupee (₹), Pakistani Rupee (₨), Japanese Yen (¥), Polish Zloty (zł), Czech Koruna (Kč), Swedish Krona (kr), and Turkish Lira (₺).
The currency symbol shows up automatically on the invoice. If you need a currency we don't have yet, the notes field is always there — just mention the currency and amount in your payment instructions.
Frequently Asked Questions
Is this really free? What's the catch?
No catch. No account, no limits, no watermarks. We make money from other tools and ads on the site. The invoice generator is free because it gets people to the site and they discover our other tools.
Is my invoice data stored somewhere?
No. Everything runs in your browser. We have zero access to what you type. Close the tab and all data disappears. If you need to edit later, you'll have to re-enter the information.
Can I add my logo?
Not yet — logo upload is on the roadmap. For now, the clean professional template works well without one. Many freelancers don't use a logo on invoices anyway.
How do I save it as PDF?
Click "Print / Save as PDF." In the dialog that opens, change the printer destination to "Save as PDF" or "Microsoft Print to PDF." Works in Chrome, Firefox, Edge, and Safari.
Do I need to charge tax?
Depends on where you live and what you sell. In the US, most services aren't subject to sales tax (but some states tax digital services). In the EU, VAT usually applies. Consult an accountant for your specific situation — this tool lets you add any tax rate you need.
What invoice number format should I use?
Whatever is consistent and sequential. INV-001, INV-002 is simple and works. Some people prefer date-based: INV-2025-001. The important thing is each invoice has a unique number. Gaps in numbering are fine — regulators care about uniqueness, not perfect sequences.
