Two P&Ls, not one
As a franchisor, you're now running two businesses at once: your own franchise-sales-and-support operation, and — indirectly, through royalty income — a stake in every franchisee's unit economics. Both need to work.
Your franchisee's math has to work first. If a location can't hit reasonable revenue and margin after paying your royalty (typically 4–12% of gross) and ad fund (typically 1–4%) on top of its own labor, materials, and overhead, no amount of brand strength fixes that — franchisees will underperform, churn, or fail, and Item 20 disclosure will eventually show it to every future prospect.
Your own math is a volume game. Royalty income per unit is a small percentage of a single location's revenue — the business only works once you have enough units for that percentage to add up. Franchisors commonly don't reach positive cash flow until 20–30 units are operating, roughly 2.5–3 years after launch. Budget for that runway, not a faster one.
The model to build before you sell anything
- A realistic per-unit P&L, using your own actual location's numbers (or a small pilot's) — not aspirational projections — to show what a competent operator can realistically earn after royalty and ad-fund obligations.
- Your own franchisor P&L, modeling royalty income against your support costs (training, field audits, franchisee-facing software, sales/development staff) at 5 units, 20 units, and 50 units — the cost structure and breakeven point change materially at each stage.
- A conservative unit-growth curve. Overestimating how fast you'll sell and open franchises is the most common franchisor planning mistake — it understates the cash runway you actually need.
Getting this modeling right before you sell your first franchise is cheaper than fixing a system that's already selling units on numbers that don't hold up in the field.
