Your busiest Saturday in July puts $3,200 in the drawer. Your quietest Tuesday in January puts $120 in the same drawer and $400 in labor. The course didn't change — the season did — and your books must make a July that pays for a January.
Mini golf course bookkeeping is seasonal hospitality bookkeeping. Admissions, birthday parties, group events, and a small food and beverage add-on peak between May and September, while rent, insurance, and landscape maintenance run year-round.
Smoothing Six Months Into Twelve
Start with a monthly cash flow map built from the prior two years of bank deposits, then express each month as a percentage of annual revenue. Many outdoor courses see 55–70% of annual revenue in June–August, 15–20% in May and September, and the rest spread across the remaining seven months.
The monthly nut: Sum every cost that runs in off-season — rent, insurance, base utilities, loan on the course build, and the minimum staffing you keep to stay open. Divide by 12. If off-season fixed costs are $9,000 per month and peak-season contribution is $18,000 per month for five months, you need to reserve $45,000 — about 50% of peak contribution — for the shoulder season.
The reserve rule: Each week in peak season, sweep a fixed percentage of collections to a separate "Off-Season Reserve" savings account. Book the sweep as a cash transfer, not an expense. The expense hits when you pay January rent from the reserve.
Admissions vs. Parties vs. F&B: Three P&Ls in One
Admissions: Walk-up tickets, per round, with peak and twilight pricing. Revenue recognized at play, not at online prepaid ticket sale — prepaid until redemption is deferred revenue.
Birthday parties and groups: A party package at $249 for 10 kids plus $12 per extra is not just admissions — it is facility time, party host labor, and a food add-on. Split the package in your ledger: Revenue — Admissions (party), Revenue — Party Host Labor Recovery, Revenue — F&B. That split tells you whether the party is profitable or whether the F&B add-on is.
Food and beverage: Often 20–35% of revenue for courses with a snack bar. Track F&B as a separate stream with its own COGS, labor, and waste. A 62% F&B margin that looks good in aggregate can hide a beverage margin of 78% and a food margin of 42% that needs a menu fix.
The Resurfacing and Refresh Budget
Mini golf assets depreciate visibly. Turf, obstacles, signage, and play equipment need replacement on a cycle, not as an emergency.
- Course surfacing: Every 5–7 years, $15,000–$30,000 depending on size and material. Accrue monthly: $22,000 / 60 months = $367 per month to a reserve.
- Props and theming: 8–12% of initial build cost annually for paint, repair, and refresh.
- POS and course management software: A fixed monthly cost, but the team that uses it turns over. Training hours are a real cost of the system.
Keep Your Finances Organized From Day One
A mini golf course is a summer business that pays winter rent. Cash flow smoothing, deferred revenue on prepaid play, and a resurfacing reserve turn a season that feels like a windfall into a year that actually profits.
Beancount.io keeps each revenue stream and each season as a version-controlled report — admissions, parties, and F&B as separate streams, and the reserve as a transfer you can audit. Get started for free and make the off-season a planned drawdown, not a scramble.
