Accounting Client Deadline Calendar and Risk List

Accounting Client Deadline Calendar and Risk List is an offline app (one HTML file in a zip) for an accounting or tax office with many clients. You enter every client's deadline with the date, the kind of work and whether you have the documents. The calendar shows the month, the Upcoming page ranks what is at risk, and one tap creates the next deadline of a repeating job after the previous one is filed.

The problem it removes: Filing dates for dozens of clients sit in several diaries, phone reminders and one partner's memory. A date is noticed when the client calls, the documents are found missing on the last day, and a recurring job is forgotten because nobody created the next one. This app puts every date you enter on one calendar and ranks them by what is actually at risk, not just by date.

What is inside:

• Month calendar of every deadline, coloured by work status, that becomes an agenda list on a phone
• Deadlines with client, kind of work, due date, documents received, work status, filed date and reference
• Risk flag per deadline: overdue, documents missing, behind on work, start now or on track, from your own settings
• Upcoming page with counts, the at risk list with WhatsApp messages to clients whose documents are missing, and dates on your weekend
• Roll forward: one tap creates the next monthly, quarterly or yearly deadline for every filed repeating job
• Printable client schedule of open deadlines and a printable deadline list
• 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: accounting and bookkeeping offices, tax agents and corporate service providers who keep many clients' filing and renewal dates and want one place to see them and the work behind them.

What it is NOT: It does not know any filing date or rule: every date is typed by you from your own sources, and it gives no legal or tax advice. It does not file anything, connect to any authority or send reminders by itself. Weekend days and the risk windows are settings you choose. 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.

Verified by us: scripted tests in Chromium (92 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 686 calculated values (25 randomised rows plus the example data) with 0 mismatches. Not tested: Safari and Firefox beyond what is stated here, and no real printer was used (print layouts were checked as PDF).
