All of these will let you generate a professional invoice PDF without paying. The differences are: signup friction, watermarks, currency support, and whether the "free" version is actually free or a 14-day trial in disguise.

Mindie's tool is the simplest pure-static invoice generator. Fill the form, hit "Download PDF". No signup gate, no email harvesting, no watermark. Currencies: USD/EUR/GBP/TRY/CAD/AUD. Line items, tax %, custom notes. Saves nothing — everything runs in your browser.
EARLY10 = $1/mo): one-click checkoutInvoice Simple's web generator is solid free option. Their mobile app adds saved clients + history but freemium-gated. Web version covers most one-off needs.
Long-standing free invoice generator. Clean output, no frills. Add their email = save invoices to your account (freemium).
Zoho Invoice has a generous free tier (up to 1000 invoices/year). Full accounting workflow. Heavy if you just need 1 invoice; great if you want client management.
Wave is free for invoicing + accounting. They make money on payments (% fee). Excellent for freelancers who want a fully free stack.
FreshBooks calls itself "free" but it's a 30-day trial. After: $19/mo. Powerful for established freelancers; overkill for occasional invoicing.
Bonsai's main pitch is "all-in-one freelance OS" — contracts, proposals, time tracking, invoices. Trial only. Premium pricing.
Invoice Home has the most templates but free version has watermark. To remove: $5/mo. Reasonable if templates matter.
Indy is freelance-focused. Free tier exists but limited. Affordable jump to paid. Worth a look if you want bundled tooling.
Free invoice tools are great for one-offs. If you bill clients hourly every month, TimeChat logs each hour as you work (via Telegram), then auto-generates and emails the invoice end of month. $7/mo. EARLY10 = $1/mo first 2 months.
