Freelancer Quote, Invoice and Time Tracker

Freelancer Quote, Invoice and Time Tracker is an offline app (one HTML file in a zip) for a one-person studio or small consultancy. You log hours against clients, write quotes with line items, raise invoices, record payments and see at a glance what is unbilled, what is unpaid and what is overdue. Quotes and invoices print as clean A4 pages.

The problem it removes: Hours are written in a notebook, quotes live in a word processor, invoices in a spreadsheet and payments in a chat thread. Nobody can say how much time is still unbilled or which invoice is two weeks late. This app keeps the whole chain, from hours to quote to invoice to payment, in one place.

What is inside:

• Client list with unbilled time, invoiced total and what each client still owes
• Time log with hours, an optional special rate, a billable tick and the invoice it was billed on
• Quotes with line items, a validity date and a status from Draft to Accepted
• Invoices with line items, discount, VAT at the rate you enter, due date, payments and balance
• Overdue list with a ready WhatsApp reminder, and unbilled time per client
• Printable quote, invoice and timesheet pages with your payment details
• Example data you can load in one click, a Start here guide and an Honest limits panel
• JSON backup and restore, CSV export, and CSV import with a check of every row before anything is added

Who it is for: freelancers, designers, developers, photographers, consultants, tutors and small studios who price by the hour or by the job and want to see unbilled and unpaid money at a glance.

What it is NOT: It does not file tax returns, and the invoice layout is not a promise that it meets the invoice rules that apply to you. Check the wording and the VAT rate with your accountant. It does not send messages or take online payments, and it keeps data only on this device, so back it up. It is not legal, tax or accounting advice, it is not connected to any government system, bank or messaging service, and it does not file or send anything by itself. UAE e-invoicing is not part of it.

Your data stays on this device in your browser. Back it up with Export; clearing browser data loses it otherwise.

Verified by us: scripted tests in Chromium (180 checks through the real screens: adding, editing and deleting records in every table, required-field messages, backup then clear then restore, CSV export then import, keyboard order, print layouts rendered to PDF, no horizontal scrolling at 375 and 1280 pixels, no network requests) and an independent recalculation by a separately written Python evaluator of 1649 calculated values (25 randomised rows plus the example data) with 0 mismatches. Safari engine (WebKit): smoke test passed; Firefox: could not be launched. Not tested: Firefox beyond what is stated here, and no real printer was used (print layouts were checked as PDF).
