It offers up to 25 isolated multi-currency workspaces, IndexedDB-based asset storage, dynamic payment QR codes (UPI, Stripe, PayPal), JSON backup/restore, offline vector PDF and PNG exports, and undo/redo editing history. The project is free to use without signup and is available on GitHub. ## Content Creating and sending professional invoices shouldn't require creating a 10th SaaS account, paying $20/month, or uploading your client's sensitive financial data to a third-party server. To solve this, I built [**Invoice Now**](https://invoicenow.ashutoshkrris.in/) - a fast, privacy-first, browser-native invoice builder engineered from the ground up to keep all your business data 100% local. ## ⚡ The Core Problem with Modern Invoicing Tools If you’ve ever tried to bill a client as a developer, creator, or agency founder, you’ve likely run into the same issues: 1. **Mandatory Signup Overhead**: Having to register, verify emails, and set up profiles just to create a simple $200 invoice. 2. **Data Privacy Risks**: Uploading private client addresses, hourly rates, and total earnings onto central cloud servers. 3. **Aggressive SaaS Paywalls**: Basic features like logo uploads, PDF exports, and multi-client management hidden behind monthly subscriptions. 4. **Context Switching**: Managing multiple brands or side projects requires logging in and out of different accounts or clearing browser state. ## 🛠️ How Invoice Now Solves It (Technical Highlights) Invoice Now takes a modern "local-first" approach. **There is no backend collecting your data.** Everything runs directly in the client's browser. Here is a quick look at what’s packed under the hood: - **🗂️ Isolated Multi-Workspaces (Up to 25 Profiles)**: Keep your freelance identity, side agency, and open-source project billing completely separate. Each workspace preserves its own currency, tax configurations, and client registries. - **⚡ High-Performance Asset Storage (IndexedDB)**: To keep state lightweight and fast, metadata lives in local state while heavy logos and graphics assets are stored locally via `IndexedDB`. - **💳 Dynamic Payment QR Codes**: Built-in dynamic payment QR code engine supporting pre-filled NPCI UPI payment links as well as custom payment gateway URLs (Stripe, PayPal, Buy Me a Coffee). - **📥 Universal JSON Data Portability**: Full backup and restore capabilities via a single `.json` file, built with cache-eviction safeguards so you never lose your data across devices. - **🖨️ Offline Vector PDF & High-Res PNG Exports**: Client-side vector PDF compilation ensuring clean, selectable text and page-slice protection algorithms so layout tables never break awkwardly across pages. - **🔄 State Engine with Chronological Undo/Redo**: Full `Ctrl+Z` / `Cmd+Z` history stack built straight into the editing canvas to revert accidental edits seamlessly. ## 📸 Feature Showcase & Tech Stack  ## 🚀 Try It Out & Get Involved Invoice Now is completely free, open-source, and ready to use without creating an account or entering a credit card. - 🌐 **Live Web App**: [https://invoicenow.ashutoshkrris.in/](https://invoicenow.ashutoshkrris.in/) - ⭐ **GitHub Repository**: [github.com/ashutoshkrris/invoice-now](https://github.com/ashutoshkrris/invoice-now) **💬 Let's discuss:** How do you currently handle client billing for your freelance or side projects? Are you using local tools, custom scripts, or SaaS platforms? I'd love to hear your feedback on the architecture! ## Similar posts on daily.dev - [How to Build a Simple PDF Invoice Generator with PHP](https://daily.dev/posts/how-to-build-a-simple-pdf-invoice-generator-with-php-ogjkch3ct) · SitePoint · 1 upvotes · 4 comments - [WorkLedger — Engineering Notebook](https://daily.dev/posts/workledger-engineering-notebook-pj2mrqvoh) · Lobsters · 0 upvotes · 0 comments - [Build an Invoice Verification App With ToolJet MCP](https://daily.dev/posts/build-an-invoice-verification-app-with-tooljet-mcp-311tjak9d) · DEV · 0 upvotes · 0 comments - [Modern and Flexible Accounting](https://daily.dev/posts/modern-and-flexible-accounting-lhvqrr3ir) · ElixirStatus · 41 upvotes · 0 comments --- Tags: [#webdev](https://daily.dev/tags/webdev), [#javascript](https://daily.dev/tags/javascript), [#open-source](https://daily.dev/tags/open-source), [#privacy](https://daily.dev/tags/privacy), [#local-first](https://daily.dev/tags/local-first) [View this post on daily.dev](https://daily.dev/posts/invoice-now-privacy-first-100-client-side-invoice-builder-h19tctwqr) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"DiscussionForumPosting","mainEntityOfPage":"https://daily.dev/posts/invoice-now-privacy-first-100-client-side-invoice-builder-h19tctwqr","headline":"Invoice Now: Privacy-First, 100% Client-Side Invoice Builder","text":"Invoice Now is a free, open-source, browser-native invoice builder that stores all data locally rather than on a server, avoiding SaaS accounts and subscription paywalls.
