Product Overview
QUOTIX is a complete, editable HTML, CSS, and JavaScript proposal builder built for freelancers, agencies, consultants, and small business teams who send quotes and proposals every week and are tired of clunky spreadsheets or paid subscription tools. You enter your business details, client information, scoped line items, a discount, a tax rate, and deposit terms, and QUOTIX instantly renders a clean, client-ready proposal you can print as a PDF, export as versioned JSON, or download as a CSV.
The build is local-first: it loads no remote assets, makes no default network request, and needs no account or server. Open Product/index.html in any current browser and you can start building proposals the same minute.
Key Features
- Integer-cent arithmetic for subtotal, discount, taxable amount, tax, and grand total, so rounding never drifts across a long proposal.
- Dynamic line items with quantity, unit price, and description, added or removed as the scope changes.
- Percentage or fixed discounts and deposits, calculated automatically and shown as separate lines on the client-facing document.
- Ten currency formats built in, so a proposal for a client in another region reads correctly without manual edits.
- Local browser save keeps a draft in place if you close the tab, without sending anything to a server.
- Versioned JSON import and export, so you can back up a proposal, hand it to a colleague, or re-open it later exactly as it was.
- Formula-safe CSV export for line items, ready to paste into a spreadsheet without formula-injection issues.
- Print-to-PDF layout tuned for a clean, single-document client handoff.
- Copy-summary shortcut for pasting a quick total into an email or chat.
- Zero runtime dependencies and zero default network requests, so the tool keeps working exactly as delivered.

- Full test suite included — the calculation vectors and unit/E2E test runners let you confirm the math after any customization.
- Documented to a professional standard — architecture, UI spec, security notes, and QA evidence are all included, not just the app.
