The Silent Killer of Restaurant Margins: Comps and Discounts

Discounts are one of the easiest costs for a restaurant to lose track of, precisely because they never show up as a separate line item on any individual guest's experience. A staff discount here, a happy hour markdown there, a birthday freebie, a loyalty reward, none of it looks dramatic on its own. Reviewed as a monthly total, discounting frequently turns out to be one of the largest, least examined expenses in the entire operation.
Why Discounts Are Different From Other Costs
Unlike rent or food cost, discounting is almost entirely self-inflicted and almost entirely adjustable, which makes it both the easiest cost to control and the easiest to ignore, since nobody's forcing the restaurant to give a specific discount the way a landlord forces a rent payment. That flexibility means discipline has to be internal, and without a system tracking it, discounting tends to creep upward gradually rather than announce itself.
Categorizing Where Discounts Actually Go
A useful audit separates discounts into categories: employee meals and shift drinks, loyalty program redemptions, service recovery comps for something that went wrong, promotional discounts like happy hour pricing, and informal "manager's discretion" comps that don't fit neatly anywhere else. That last category is usually where the real leakage hides, because it's the least structured and the least reviewed.
- Track total discount dollars as a percentage of gross revenue, not just as an absolute number
- Break the percentage down by category to see which type of discounting is actually driving the total
- Set a threshold, even an informal one, for what a healthy discount percentage looks like for your concept, and investigate months that exceed it
- Require a reason code on every discount applied through the POS, the same way voids and comps should be coded

The Manager Discretion Problem
Giving managers the ability to comp or discount on the spot is genuinely valuable, it lets real problems get resolved immediately without a guest waiting for corporate approval. But discretion without any tracking or review tends to drift over time, especially with multiple managers whose personal generosity thresholds vary widely. A manager who comps liberally isn't necessarily doing anything wrong, but if their discount rate is triple another manager's with no clear operational reason, that gap is worth understanding.
Setting Guardrails Without Removing Judgment
The goal isn't eliminating manager discretion, it's putting reasonable limits and visibility around it. A tiered approval structure, where a manager can comp up to a certain dollar amount independently but anything larger needs a second sign-off or a documented reason, preserves the ability to fix real problems on the spot while catching the pattern before it becomes a significant unplanned expense.
Reviewing Discount Trends the Same Way You Review Food Cost
Most restaurants review food cost percentage religiously every month but never build the same habit around discount percentage, despite it often being a comparable or larger drag on margin. Adding a discount review to the same monthly financial routine used for food and labor cost turns an invisible leak into a number that gets the same scrutiny as every other major expense on the P&L, which is usually all it takes to bring it back under control.
