Event Package Quote Builder with Add-ons and Confirmed Dates

Event Package Quote Builder with Add-ons and Confirmed Dates is an offline app (one HTML file in a zip) for a planner, caterer or venue that sells events as packages. You list your packages and add-ons once with their prices. For each enquiry you pick the package, enter the guest count and tick the add-ons, and the app works out the extra guest charge, the add-on total, the discount, VAT, the total and the deposit. When the client says yes the event goes on the calendar.

The problem it removes: Package pricing is worked out again for every enquiry on a calculator or an old spreadsheet. The extra guests are forgotten, a per guest add-on is priced as a flat fee, the discount drifts, and a date is promised to two clients because nobody looked at the calendar. This app prices every quote the same way from your own price list, prints it with the same layout, and refuses to confirm a date that is already taken.

What is inside:

• Packages with a base price, included guests and a price for each extra guest, so the quote follows the guest count
• Add-ons priced per event, per guest or per hour, with an optional price for one quote only
• Quote with discount percentage, a limit you set for the discount that flags quotes above it, VAT from Settings, deposit percentage and amount, and a valid until date
• Quote states Draft, Sent, Accepted and Declined, with Expired shown for quotes that were not answered in time
• Calendar of accepted events, a rule that stops more confirmed events on a date than you allow, and a warning on other quotes for a date already taken
• Today page with quotes to chase (with WhatsApp links), deposits not yet received, events in the next 30 days and a printable quote and event confirmation
• 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: event planners, wedding and party organisers, caterers and venue managers who sell fixed packages with optional extras and answer enquiries by phone and chat.

What it is NOT: It does not send quotes, take payments or hold contracts. It has no supplier cost, margin or staff scheduling, no guest list or seating and no online booking page. It does not decide what VAT applies: you enter the rate. Cancellation and refund terms are your own text on the printed quote. 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 (147 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 1945 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).
