Your decisions. Your numbers.
Run the day.
Read what happened.
Choose what to charge, how much to stock, who to schedule, and when to invest. Customers respond, costs arrive, equipment wears down, and the books reveal whether the plan worked.
A short guided lemonade stand introduces the basics. From there, businesses ranging from cafés and bookstores to gyms, repair shops, online retail, and service crews introduce new operating models and tradeoffs.
Watch the system respond.
See how demand, service, capacity, costs, cash flow, morale, and reputation interact over time.
Use the evidence.
Trace a weak result back to its cause, revise the plan, and discover why a profitable business can still run short of cash.

A handbook written by play
Learn it when
your choices reveal it.
The Business Handbook unlocks lessons when your own decisions cause the underlying business idea to appear. A stockout, a long line, a cash squeeze, or a successful price change makes the concept timely and concrete.
Lessons span pricing, profit, finance, customers, operations, staffing, and inventory. They explain ideas such as gross margin, cash runway, demand forecasting, bottlenecks, labor cost, reorder points, and many more.
