Free invoice generators that don't make you sign up

“Free invoice generator” covers four quite different deals, and the difference only shows up after you have typed in a client’s address. Before comparing anything, it is worth separating them:

• Free to use, no account. You open a page, fill it in, download a PDF. Nothing is stored anywhere you have to log back into.
• Free with an account. Genuinely free, often unlimited, but you are creating a record with a company and your invoices live on their server.
• Free trial. Fourteen days, then a card. Usually described as “start for free” on the pricing page.
• Free tier with a cap. Free until the fourth invoice this month, then an upgrade prompt.

All four get marketed with the same word. Here is what each of the main options actually is.

The ones that need no account

invoice-generator.com does exactly what the name says. Its own page claims “Create and download invoice PDFs for free with no signup required” and “Generate unlimited invoices for free”. There is no account and no cap. The trade-off is that nothing persists: close the tab and the invoice is gone unless you saved the PDF, so there is no client list and no numbering sequence carried forward.

BidPaper — this site — is the other one. No account, no cap, and documents are saved in your browser rather than on a server, which means a client list and a running invoice number without anyone holding your data. The honest limits: it is new, there is no mobile app, and it does not take card payments. It is also built for the trades specifically, with line-item libraries per trade, which is useful if you are a plumber and irrelevant if you are a freelance designer.

The ones that are free but want an account

Wave has the most generous free tier in this list. The Starter plan covers “unlimited estimates, invoices, bills, and bookkeeping records” at no cost, with card payments at 2.9% + $0.60 per transaction. It is real accounting software underneath. You need an account, your data sits with them, and the Pro plan at $19/month adds bank imports, receipt capture and late-payment reminders.

Zoho Invoice advertises itself as free invoicing software for small businesses and asks you to sign up and verify an email address. Its homepage does not state what limits apply to the free plan, so check that before committing — we are not going to quote a number we could not find on their own page.

The one that is a trial, not a free tier

Invoice Simple is excellent software with a very good mobile app, and it is not free. The pricing page offers a 14-day trial, after which plans are metered by volume: $6.99/month allows up to 3 invoices a month, $14.99 allows up to 10, and unlimited costs $21.99. If you send two invoices a month that entry tier is cheap. If you send twelve, read the tier boundaries carefully before you subscribe.

Side by side

	Account needed	Invoice limit	Cost to start
invoice-generator.com	No	Unlimited	Free
BidPaper	No	Unlimited	Free
Wave	Yes	Unlimited	Free (Pro $19/mo)
Zoho Invoice	Yes	Not stated on their page	Free
Invoice Simple	Yes	3/mo at entry tier	14-day trial, then $6.99/mo

What actually bites people

The cap is usually monthly, not total. “Up to 3 invoices” sounds generous until a busy month. Check whether the limit resets and whether exceeding it blocks sending or just nags.

Watermarks are rarer than they used to be, but check the output. The place to look is the footer of the downloaded PDF, not the preview on screen. A small “made with” credit is normal; a diagonal stripe across the page is not something to send a customer.

Getting your data out matters more than getting it in. If invoices live on a server, find the export before you need it. Account-based tools generally let you download PDFs while you are subscribed — the problem arrives when the subscription lapses and the history goes with it. If your documents are stored locally instead, the opposite risk applies: clearing your browser data deletes them, so take a backup.

Free almost always means something. Ads on the content pages, a paid tier you are being walked towards, or payment processing fees. None of those are sinister, but it is worth knowing which one you are paying before you build a year of invoicing on it.

Which to pick

If you need one invoice today and will never think about it again, use invoice-generator.com — no account, no residue.

If you want bookkeeping, bank feeds and card payments in one place and do not mind an account, Wave’s free tier is the strongest offer here.

If you are a contractor who writes estimates as well as invoices, wants trade line items already loaded, and does not want an account, that is the specific gap BidPaper was built for. If you want card payments inside the tool, it is not — use one of the others.
