The event budget that adds itself up — built by an event director, not a software company. Every cost line lives in one master table: block, category, supplier, quantity, price, status. From it, the app draws the overview your client actually asks for: total, by category, by event block, per participant. Change a price once. Every number follows.
One table. Every total draws from it. Nothing is copied anywhere, ever.
The event budget is the spreadsheet that decides whether the event happens. It is also the one where a typed-over formula costs real money. Budget Master keeps one master table — every cost line once — and computes everything else: block subtotals, category totals, cost per participant, how much is confirmed. This is the first working budget for client discussions, not an accounting system.
One row per cost line. Block, category, supplier, item, quantity, unit, unit price — the total computes itself, always. Line IDs (WEL-001…) assign themselves per block. Write European numbers the way you write them: 35,02 works. If a quantity or price isn't a number, the cell turns red — no silent zeros in a client budget.
⚙ Event set-up holds the event blocks (Welcome Dinner, Conference Day, Accommodation…) with a participant count per block, and the total participant count for the event. The blocks group the table; the participant counts drive cost per person — overall and per block.
Every line carries a cost category: A Accommodation, B Venue, C Catering, D Programme, E Production, F Purchases, G Transport, H Marketing, I Other. The overview sums them with one letter's discipline and none of the SUMIF. Rename them or add your own in ⚙ Event set-up.
Every line is an Estimate, an Offer, Booked, Confirmed or Cancelled. Cancelled lines stay visible, struck through, out of every total — the change log writes itself. The bar in the toolbar shows how much of the budget is committed money (booked + confirmed) versus guesses.
＋ column adds a column to the master table — invoice number, cost centre, VAT class, whatever your event needs. Your columns ride along in the CSV export and print. The built-in columns feed the overview; yours are for you.
Total budget, totals by category with shares, totals by block, cost per participant, commitment and top suppliers — drawn live from the master table. This is the page you put in front of the client. Prints A4 portrait. 🔗 Share includes a link that opens straight into this view.
▶ Present is the full-screen dark view for budget meetings: the total, cost per participant, category bars, block totals. Nobody reads a spreadsheet off a wall. This they read.
🗂 Line library holds the standard costs of a corporate event — venue hire, buffet menus, drink tickets, security, shuttle packages, hotel nights — each with the right category and unit, and an honest note from someone who has paid these invoices. Add one to a block and put your price in.
