An offline browser app for freelancers and small businesses to write quotes, issue invoices, record the payments actually received and see the recorded cash position. Opens in desktop Chrome or Edge, keeps data on your computer and comes with a fictional sample, sample PDFs and a JSON demo backup. One-time digital download.

The problem it solves

Quotes sit in one file, invoices in another and payments in your head, so it is hard to tell what has really been received and what is still outstanding.

Who it is for

Freelancers, studios and small service businesses that want a simple local tool for quotes, invoices and cash, without a subscription or an account.

What you get

• Create quotes and invoices with line items, entered tax rates, due dates and a live total preview
• Convert an unexpired quote into one linked invoice; the client and line items copy over
• Record each payment you actually receive: part payments update the remaining balance and overdue invoices stand out
• A cash position screen separates billed from banked: opening balance + received payments - paid expenses, for any date you choose
• Corrections stay visible: reverse a full entry with a reason instead of overwriting history
• Download invoice, quote and cash report PDFs, export the ledger as CSV and keep a complete JSON backup
