The short answer: if you want the simplest path to a professional invoice you can email to a client — free, with no ads and no watermark — use Simple Invoice Generator (that's us, and yes, we'll give you the honest cons too). If you need full free accounting alongside invoicing, use Wave. If your clients already pay you through PayPal, use PayPal Invoicing and accept the fees. The right tool depends on what "free" needs to cover for you — here's the honest breakdown.
We build one of the tools on this list, so read this as an informed comparison, not a neutral one. To keep ourselves honest: every tool below includes real drawbacks, including our own.
What "free" actually means (read this first)
Free invoicing tools fall into three groups, and most disappointment comes from picking the wrong group:
- Instant generators (no account) — fill a form, download a PDF. Fast, but nothing is saved: no client list, no payment tracking, and often ads or watermarks.
- Freemium invoicing apps — a real account with saved clients and invoice tracking, free up to a limit (invoices, clients, or features).
- Free accounting suites — invoicing bundled inside bookkeeping software. Powerful, but heavier than most freelancers need.

1. Simple Invoice Generator — simplest way to send a real invoice free
Best for: freelancers and small businesses who want to create, send, and track invoices without learning accounting software.
Simple Invoice Generator is built around one idea: invoicing should take two minutes, not a tutorial. On the free plan you can create up to three invoices with no credit card: add your logo, line items, taxes and discounts, then export a clean PDF or email the invoice straight to your client with the PDF attached — a feature many free tools gate behind a paid plan. You can save clients for one-click reuse, track each invoice as draft, unpaid, paid, or overdue (overdue flips automatically when the due date passes), and set a different currency per invoice across 9 currencies (USD, EUR, GBP, CHF, CAD, AUD, JPY, INR, RSD). You can also fill in an invoice and download the PDF without creating an account.
The honest cons: the free plan is capped at three invoices total — enough to run a real project or two end-to-end, but if you invoice monthly you'll hit it and need Pro ($9/month or $79/year for unlimited). Free-plan PDFs also carry a small "Created with Simple Invoice Generator" line at the bottom, which Pro removes. And it's deliberately not an accounting suite: no bookkeeping, no expense tracking, no recurring invoices, and clients can't pay by card from the invoice. It does one job.
2. Wave — best if you want free accounting too
Best for: US/Canada freelancers who want invoicing and bookkeeping in one free tool.
Wave has been the reference "genuinely free" answer for years: unlimited invoices, client records, and basic accounting, funded by payment-processing fees rather than subscriptions. If you want your invoices to reconcile automatically against your books, nothing free comes close.
The honest cons: Wave has recently moved several formerly-free features to its paid plan — including automatic bank-transaction import and removing the Wave logo from your invoices. Its card-processing fees (2.9% + $0.60 on the free plan) are on the higher side. And outside the US and Canada, Wave no longer lets you email invoices or reminders at all, only share a PDF or link, and its payments and Pro plan aren't available. It's also an accounting platform first, so the invoicing flow carries more complexity than a pure invoice tool.
3. Zoho Invoice — most features on a genuinely free plan
Best for: freelancers who want maximum functionality free and don't mind a denser interface.
Zoho Invoice is free and unusually complete: invoices, quotes, recurring billing, automatic reminders, expenses, time tracking, a customer portal, and online payments through gateways like Stripe and PayPal. If you want the most capability without paying anything, it's the feature champion.
The honest cons: it feels like enterprise software scaled down — more menus and setup than a freelancer sending a handful of invoices needs. The free plan is capped at 500 invoices a year and two users, invoices carry "Powered by Zoho Invoice" branding, and you can only invoice in your base currency; for more, Zoho points you to its paid Zoho Billing.
4. Invoice Ninja — best for the technically inclined
Best for: tech-savvy freelancers, or anyone who wants to self-host their invoicing.
Invoice Ninja's hosted free plan gives you unlimited invoices, recurring invoices and multiple currencies for up to 5 clients, and the source code is available, so you can run it on your own server and own your data completely. Reviewers consistently rank its functionality-per-dollar near the top.
The honest cons: the same reviewers mention a steeper learning curve. On the hosted free plan, invoices carry "Created by Invoice Ninja" branding and automatic reminders need Pro ($14/month since January 2026). Self-hosting is free, but under the Elastic License rather than a true open-source licence, and it means running your own server.
5. PayPal Invoicing — best if your clients already use PayPal
Best for: freelancers whose clients pay by PayPal anyway.
Creating and sending invoices through PayPal is free, and the payment step is where it shines: clients click, pay by PayPal or card, done. If your money already flows through PayPal, it's the path of least resistance.
The honest cons: in the US, PayPal takes 3.49% + $0.49 of each invoice paid through PayPal (2.99% + $0.49 when the client pays by card; fees as of 1 October 2026), customization is minimal, and each invoice carries PayPal's branding rather than yours. You're renting their ecosystem, not building your own.
6. invoice-generator.com — fastest one-off invoice, nothing more
Best for: a single invoice, right now, with zero commitment.
No signup, instant PDF. For a one-time bill to a one-time client, it does the job in a minute.
The honest cons: independent reviews flag the ads and pop-ups, and there's no per-line tax handling. Most importantly, nothing is saved — no client list, no history, no "did they pay me?" tracking. Fine once; painful as a system.
7. Canva invoice templates — prettiest, most manual
Best for: designers who care about a distinctive invoice look.
Canva's invoice templates are the best-looking in this list, and free to customize.
The honest cons: they're static designs. Nothing calculates — you type every subtotal, tax, and total yourself, and a typo becomes a billing mistake. There's no client management or tracking. It's a design tool wearing an invoice costume.

Frequently asked questions
What's the catch with "free" invoice generators?
Usually one of four: ads/watermarks on your PDF, a cap on invoices or clients, essential features (like emailing invoices) gated behind paid plans, or payment-processing fees. Every tool above monetizes somewhere — the table shows where.
Can I send an invoice by email for free?
With Simple Invoice Generator, Zoho Invoice, Invoice Ninja, and PayPal — yes. With Wave, only if your business is in the US or Canada. With instant generators and Canva, you download the PDF and attach it to your own email.
Do free invoice generators work for international clients?
Check per-invoice currency switching. Simple Invoice Generator supports 9 currencies set per invoice; Wave and Invoice Ninja also handle multiple currencies; Zoho Invoice only invoices in your base currency. Instant generators vary, and some only set currency account-wide.
Is a Word or Excel invoice template good enough?
It works, but everything is manual: no auto-calculations, no tracking, easy to make totals errors. Any tool on this list is faster and more professional after your second invoice.
