Restaurant Group CFO: Prime Cost, Unit Economics, and When to Bring One In

One restaurant can be run on instinct and a good bookkeeper. Three or more usually can't. Once a group has multiple locations, the owner needs to know which units carry the others, what prime cost looks like by store, and whether the next lease will make money. That is the point where a restaurant group CFO, often on a fractional basis, starts paying for itself.

Prime cost is the number to manage weekly

Prime cost is cost of goods sold plus total labor, including payroll taxes and benefits, as a percentage of sales. Industry guidance commonly targets prime cost in the low-to-mid 60s as a share of sales for full-service concepts, with quick-service running lower. The exact target matters less than seeing it weekly, by location, while there is still time to adjust schedules and ordering.

What a fractional restaurant CFO builds

• A location-level P&L with consistent account mapping, so store managers are compared on the same basis.
• A weekly flash report covering sales, prime cost, labor hours and cash, delivered by Tuesday.
• A 13-week cash flow that accounts for rent, sales tax, payroll cycles, and vendor terms.
• Unit economics for growth. Build-out cost, ramp period, payback and cash-on-cash return for each new location before the lease is signed.
• Systems that scale. Many groups move to a restaurant-specific platform such as Restaurant365 to tie POS, inventory, AP and the general ledger together. A CFO plans the conversion so history isn't lost.

When to bring one in

Common triggers are opening a third or fourth location, taking on investors or a bank loan, a location that is losing money with no clear reason why, or an owner who is still approving every invoice personally. Our guide to outsourced CFO services for hospitality goes deeper on scope and cost.

Common questions

What is a good prime cost for a restaurant?

Targets vary by concept; full-service operators often aim for the low-to-mid 60s as a share of sales. Track it weekly by location.

Do restaurants need a CFO or a controller?

Most groups need clean, timely books first. A fractional CFO adds forecasting, unit economics and capital decisions once the close is reliable.
