Decisions and troubleshooting.
Should contingency be applied to income as well as costs?
Use the intended budgeting rule explicitly. A cost reserve and an income forecast are different parts of the plan.
Why does the budget exceed the venue quote by more than expected?
Service charges, equipment, staffing or minimum catering commitments may be separate. Compare the quote's scope with every budget line.
