Every single one had a catch:</p> <ul> <li> <strong>Watermarks</strong> on the PDF unless you pay</li> <li> <strong>"Free" = 3 invoices</strong>, then a paywall pops up</li> <li> <strong>Forced signup</strong> just to download a PDF you just created</li> <li> <strong>Ugly templates</strong> that look nothing like the screenshots</li> </ul> <p>So I built <a href="https://www.invoicelark.com" rel="noopener noreferrer">InvoiceLark</a> — a completely free, no-signup invoice generator.</p> <h2> What it does </h2> <ul> <li> <strong>Truly free</strong> — no signup, no watermark, no invoice limits</li> <li> <strong>No logo? Auto-generate one</strong> — type your business name and it creates a letter-badge logo instantly</li> <li> <strong>6 templates</strong> (Modern, Classic, Minimal, Compact, Bold, Clean) and 6 currencies</li> <li> <strong>Built-in hourly rate calculator</strong> — handy for freelancers who bill by the hour</li> <li> <strong>Payment QR codes</strong> — add a PayPal link and a scannable QR code prints on the PDF</li> <li> <strong>Save clients &amp; items</strong> — local storage, no data ever uploaded</li> <li> <strong>JSON/CSV export</strong> — your data is yours, always</li> </ul> <h2> Why I built it </h2> <p>I got tired of invoice tools that feel like they're designed to trap you into a subscription. It's a form + a PDF generator — it shouldn't need a backend or a login.</p> <p>Everything runs in the browser. No server, no database, your invoice data stays on your device.</p> <h2> What I learned </h2> <ul> <li> <strong>Free tools can be genuinely good.</strong> You don't need Stripe integration or a SaaS backend if your goal is simple: fill form, download PDF, done.</li> <li> <strong>The "no logo" problem.</strong> Most invoice generators assume you have a logo file ready. A lot of freelancers don't. Auto-generating one was the most appreciated feature.</li> </ul> <p>Built with vanilla JS and a lot of coffee. Would love your feedback! What features would make invoicing suck less for you?</p> freelance productivity showdev sideprojects
