Retreat budgets almost never blow up on the obvious things. It's the airport transfers, the extra night someone needed, the AV rental nobody scoped — a dozen small lines that quietly add up to a nasty surprise at invoice time.

This tracker keeps every cost visible from the first deposit to the final settlement. Category tabs, automatic per-person and per-day maths, and a plan-versus-actual view so you catch overruns while you can still do something about them.

• Cost category tabs: venue, travel, F&B, activities, production
• Automatic per-person and per-day calculations
• Deposit and payment schedule with due-date tracking
• Plan vs. actual comparison to catch overruns early
