Wedding Budget and Vendor Payment Schedule Tracker

Wedding Budget and Vendor Payment Schedule Tracker is an offline app (one HTML file in a zip) for a wedding planner or a couple. Each wedding has a total budget. Each budget line has an estimate, the agreed price once the vendor quotes, and a schedule of deposits and instalments. The app adds it all up and shows what is paid, what is due next and what is overdue.

The problem it removes: Budgets and deposits live across chat threads, a vendor is paid twice or not at all, and the final payment date is found out when the vendor calls. Nobody can say quickly whether the wedding is over budget now that three quotes have come in above the estimate.

What is inside:

• Weddings with a budget, event date and days to go, with planned total, remaining budget, paid so far, balance still to pay and overdue amount, all calculated
• Budget lines by category and vendor with an estimate, the agreed price, status and a count of what is paid and what is left
• Payment schedule per line: deposit, instalments, final payment and refunds received, each with a due date and a paid tick
• Today page: payments overdue, payments due soon with a WhatsApp reminder to the couple, weddings over budget and agreed prices with no payment dates yet
• Rules that stop mistakes: scheduled payments that add up to more than the agreed price, a booked line with no agreed price, marking a line paid in full when it is not
• Printable budget summary and payment schedule for a wedding, and a vendor statement across weddings
• 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: independent wedding planners, small planning studios and couples who plan with many vendors and pay in deposits, and want to see budget and payment dates in one place.

What it is NOT: It does not pay vendors, hold money or send reminders by itself. It is not a contract and does not hold vendor terms or cancellation rules: it records the amounts and dates you type. It has no guest list, seating or invitations. 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 (158 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 1501 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).
