What problem does it solve? Planning a conference or hackathon budget usually means guessing at costs, picking one break-even number, and discovering too late that deposits leave before sponsor money lands. This Skill builds a complete financial model for one edition of a technical event so every line is quoted or honestly labelled, and cash timing is visible before commitments are made. ## Core Features & Use Cases - Cost taxonomy with fixed/per-head split: Lists every cost line from the format's own taxonomy (conference or hackathon, never blended), classifies each as fixed, per-head, or per-speaker, and budgets quantities off the expected show-up number rather than registrations. - Good/Better/Best scope tiers: Costs three fully-priced versions of the event with a break-even each, so a revenue shortfall has a pre-decided downgrade ladder instead of a cancellation. - Contingency as a three-tool stack: Combines an absolute cash floor, a labelled pad on estimates, and the downgrade ladder, without quoting any percentage as an industry convention. - Dated cash-flow schedule: Places every outflow and inflow on its real date, identifies the lowest cash point, and routes tax questions to a fiscal host or accountant instead of answering them. - Use Case: A 250-person community conference has one venue quote and nothing else. The Skill interviews the organizer, carries the quote as dated, marks catering and AV as explicit placeholders, sets sponsorship and ticket targets for handoff to pricing skills, and delivers three costed tiers with a cash-flow trough. ## Quick Start Ask the assistant to build a budget for your event, stating the format, expected attendance, which quotes you already hold, and who holds the money.
