Invoice Chase Desk

Invoice Chase Desk is an offline app: one HTML file in a zip that opens by double-click, with no installation, internet or subscription.

The problem it removes: Most small UAE businesses chase invoices from memory: someone remembers a customer owes money, sends a message when they have time, and nobody knows who was already chased last week or who promised to pay on the fifteenth. Promises are forgotten, polite customers get chased three times and slow payers not at all, and the money you are owed sits a month longer than it should.

What is inside:

• Import your unpaid invoices from a CSV export (customer, invoice number, dates, outstanding amount, optional phone and email), with a column-mapping step; importing again updates the amount of invoices already there
• A Chase today list: customers who are overdue, have no promise pending and have not been chased inside the number of days you set, biggest overdue first
• Reminder wording for WhatsApp and email with the customer name, invoices and amounts filled in, chosen by how late the oldest invoice is; you edit the wording and copy it. The app does not send anything
• A chase log: how you chased, what happened, the promised date and amount; a broken promise shows in red on the dashboard
• Ageing by customer in buckets you define, counted from the due date or from the invoice date
• Printable statement per customer, or all customers at once
• Record payments against an invoice, add invoices by hand, CSV export of invoices and the chase log
• Example data and an example open-invoices CSV, JSON backup and restore, Clear everything

In the zip: index.html (the app), README.txt (quick start, how it calculates, limits) and EXAMPLE-DATA with a made-up example you can restore, plus 1 example CSV file in the layout the importer expects. Start in 10 minutes: open index.html, press Load example data, look around, press Clear everything and enter your own settings.

Rules are settings, not built in. Bucket limits, the number of days before the same customer is chased again, the default payment terms used for imports without a due date and the reminder wording are all settings. The reminder wording is a starting point, not legal advice.

Who it is for: owners, sales administrators and accounts staff of businesses that invoice on credit and want a simple, repeatable weekly chase routine.

What it is NOT: accounting software and it does not read your books: the balances are what you import or type, so keep them in step with your accounts. It does not send messages, and it is not legal advice on threatening action or reporting a debtor. Receivables Ageing and Chase Tracker is an Excel workbook; this is a separate offline app with CSV import, a chase list driven by rules, promise tracking and ready message wording. It does not set credit limits: Customer Credit Limits and Statements does that.

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

Verified by us: 58 scripted checks through the real screens in Chromium, run at 1280 px and at 375 px, with an independent Python calculation of the ageing buckets and the chase list compared with what the app shows, plus a CSV import with semicolons, month-name dates and deliberately bad rows (skipped with reasons). The statement was rendered to PDF in Chromium and looked at. The example CSV shipped in the zip was imported through the real Import screen with no rows skipped. Not tested in Firefox or Safari (neither could be launched in our test environment), in Edge, on a real phone, on a real printer, or with real bank or accounting exports; layout checked at 375 px and 1280 px.
