Restaurants sit awkwardly in commercial finance. They collect cash instantly, which sounds like an advantage, and it removes the asset that most working capital lending is built on. A six-unit operator with strong margins can find itself with fewer financing options than a distributor half its size.
Why is restaurant financing structurally different?
Because there are no receivables. Card settlements arrive within days, so at any moment the balance sheet holds almost no accounts receivable, modest food inventory, and a large amount of leasehold improvement that cannot be sold.
Asset-based lending needs assets that convert to cash independently of the business. A restaurant’s value is almost entirely in its going concern: the location, the lease, the brand, and the operator. Those are real, and none of them is collateral in the sense a borrowing base requires.
What do lenders look at instead?
Unit economics, and specifically four-wall margin. Four-wall margin is the profit a single location produces after all costs controllable at that location, before corporate overhead, and it is the number that tells a lender whether opening another unit creates value or repeats a mistake.
| Metric | What it measures |
|---|---|
| Average unit volume (AUV) | Annual sales per location |
| Four-wall margin | Unit-level profit before corporate overhead |
| Occupancy as a share of sales | Lease burden, the hardest cost to change |
| Prime cost (food plus labour) | Operating discipline |
| Sales per square foot | Format efficiency |
A worked example
A six-unit group:
| Line | Amount |
|---|---|
| Average unit volume | $1,400,000 |
| Four-wall margin, 15% | $210,000 per unit |
| Six units | $1,260,000 |
| Corporate overhead | ($450,000) |
| Company EBITDA | $810,000 |
Two things follow from that table. Overhead consumes 36% of the four-wall profit, so the seventh unit is worth far more than the average unit, because its margin lands almost entirely at the bottom line. And a single underperforming location at 5% four-wall margin costs the company $140,000 against the average, which is 17% of total EBITDA.
Lenders read the unit-level distribution, not the average. Ask any operator for four-wall margin by unit for 24 months, and the answer separates the well-run groups from the rest immediately.
What actually funds expansion?
Four sources, each fitting a different piece.
- Equipment finance for the kitchen package, secured by identifiable equipment with a resale market.
- SBA lending for build-out, acquisition of an existing location, and real estate. The timeline and requirements are covered in SBA 7(a) requirements and the real timeline.
- Sale-leaseback, where units are owned rather than leased, which converts the property into build-out capital as described in sale-leaseback.
- Landlord tenant improvement allowances, which are financing in everything but name and are negotiated rather than applied for.
Notably absent from that list is a conventional working capital revolver, because there is little to advance against.
Why do restaurants end up in expensive short-term capital?
Because the build-out is a large upfront cost against a location with no operating history, and the traditional sources above are slow. An operator with a signed lease, a contractor scheduled, and an opening date is under a timetable that a 60 to 90 day credit process does not fit.
That timing mismatch, rather than credit quality, is what routes healthy restaurant groups into daily-remittance products whose real annualised cost is set out in revenue-based financing. Recognising the mismatch early is what avoids it: the financing decision belongs before the lease is signed, not after.
What does the lease do to financeability?
More than almost anything else. Occupancy cost is effectively fixed for the term, so a lease signed at an aggressive rent permanently caps the unit’s margin. Lenders read the rent as a share of sales and treat a high ratio as a structural constraint rather than a temporary one.
Two lease provisions matter for financing specifically: whether the lease is assignable on a sale of the business, and whether the landlord will sign a waiver allowing a lender access to equipment on the premises. A lender that cannot get to the collateral will discount it heavily.
How is a multi-unit group valued?
On a multiple of EBITDA, with the multiple driven by unit count, consistency across units, and whether the concept has demonstrated it transfers to new locations. The gap between a group whose units perform consistently and one carrying two weak locations is wider in the multiple than in the earnings, and the reasons are the same ones set out in why serial acquirers command a higher multiple.
Fixing or closing the weakest unit before a sale process is usually worth more than the unit’s own contribution.
The short version
Restaurants have cash and no collateral, so financing runs on unit economics rather than a borrowing base. Four-wall margin by unit, occupancy as a share of sales, and the lease terms decide what is available. Line up the capital before the lease is signed, because the timetable, not the credit, is what pushes good operators into bad money.
