An event budget that falls apart halfway through almost never fails on the big line item: it fails on the one you forgot to include. Building a realistic one means going line by line with real quotes—not rough estimates—and leaving a margin for what always shows up.
At SOMOS DER we build full budgets with real numbers. Here’s the structure.
The line items you can’t leave out
- Venue — renting the space and its conditions.
- Technical production — sound, screens, lighting, stage.
- Logistics — transport, transfers, accommodation.
- Lodging — if you have out-of-town guests or delegations.
- Catering / food — from coffee breaks to full food zones.
- Access control — system, scanners, staff.
- Security — personnel, plan, coordination.
- Streaming / content — if the event is broadcast or documented.
Every event adds or drops items, but this is the baseline. The most common mistake is budgeting only for what’s visible (stage, catering) and forgetting the invisible parts: access, permits, insurance. Those are exactly what show up later and break the number.
No estimates: quotes
The difference between a budget that works and one that doesn’t comes down to one word: real. A rough number gives you a false sense of control. A quote requested from an actual vendor gives you a number you can decide on.
That’s why we request quotes from multiple vendors per line item: to get a real price range, to compare and to negotiate. “The sound will run roughly X” is not the same as three real quotes on the table.
The margin for the unexpected
Every event has surprises. A vendor raising their price, an extra permit, a weather contingency. A realistic budget includes a margin for that. It’s not pessimism: it’s the difference between solving a surprise with your wallet or with a heart attack.
The budget as a decision-making tool
Built well, the budget isn’t a formality: it’s what tells you whether the event is viable. With all the real costs on the table, you can decide whether to move forward, adjust the scope or look for more sponsorship. Without it, you’re guessing.
