Promotions for restaurants tend to have a side effect nobody intends: they lower the average spend instead of raising it. The fixed-price menu, the 2-for-1 on mains or the 20% discount do bring in tables, yes, but they also teach the customer to spend less and to come only when there's an offer. You fill the place on a Tuesday and empty the till.
The mistake is confusing promotion with discount. A discount cuts margin to win volume. A good restaurant promotion does the opposite: it uses an incentive to get the customer to order more, try something new, or come back, without touching the price of what they were already going to consume. The difference between the two is what separates a promotion that makes you money from one that eats it.
Why most promotions lower the margin
Before designing anything, it helps to understand what makes a promotion subtract rather than add. It's almost always one of these three faults.
It rewards what the customer was already going to order. If you discount the star dish, you're giving away margin on a sale you already had. The incentive only makes sense on what the customer wouldn't have ordered without it.
It trains the customer to wait for the offer. A recurring, predictable promotion teaches people to come only when there's a discount. You've turned your normal menu into "the expensive one."
It has no expiry date. Without urgency, the offer accelerates nothing. The customer postpones it, and a postponed promotion generates no extra sale.
Promotions that raise the average spend
These mechanics are built to increase spend per table, not to empty the bill.
The prize redeemed by ordering something more. The customer wins a free dessert or coffee, but only if they order a main. The incentive pushes the sale of the dish, and the cost of the gift is a fraction of what they've spent extra.
The upgrade instead of the discount. Rather than dropping the price of the glass of wine, you offer to move from the house glass to a reserve for the same price on a specific occasion. The customer perceives value, you keep the margin, and you show them a superior product they might repeat.
The suggested pairing or combo. You reward or run a draw among those who order the starter + main + drink combo. You raise the average spend by bundling, without it looking like you're selling more.
The second-round incentive. A mechanic active only above a certain spend —a draw, an instant prize— encourages ordering that dessert or last drink that would normally go unordered.
The prize for coming back, not for today. The customer wins something they can only redeem on their next visit. It costs you no margin today and guarantees one more visit, which is where the recurring business lives.
The draw among high bills. Every bill above a certain amount enters a weekly draw. You drop no price and yet you give a reason not to skimp on dessert or the second bottle, because every extra euro brings the prize closer.
The mistake of rewarding what already sells
The most expensive trap in restaurant promotions is rewarding base consumption. If you give something free for ordering what the customer was going to order anyway, you've turned a normal sale into a discounted one.
Always tie the prize to incremental spend. The incentive should push the customer one step above what they planned: an extra dish, a higher category, an additional visit. If there's no increment, there's no promotion, there's a giveaway.
Keep the cost of the incentive marginal. A coffee, a shot or a low-cost dessert have a very high perceived value and a low real cost. That asymmetry is exactly where a promotion becomes profitable.
How to measure whether the promotion works
A promotion without measurement is an expensive hunch. Decide beforehand which number you'll watch and compare it with your normal situation.
Average spend of the tables that took part. The metric that matters. If the promotion tables spend more than average, you're on track. If they spend the same or less, the promotion is subtracting.
Incremental redemption rate. How many customers ordered the extra dish to activate the prize. It measures whether the incentive is moving real consumption.
Repeat visit. Of those who played, how many came back. It's the metric that justifies promotions built for the next visit.
The mechanic that ties incentive to data
The ideal promotion for a restaurant raises the bill today, brings the customer back tomorrow, and leaves you a contact along the way. And all of that should happen with no friction, at the moment of payment.
With PrizeQR you set it up without asking the customer to install any app: they scan a QR on the table or receipt with their phone camera, instantly discover whether they've won a prize you've defined —a dessert redeemable today with a main, a drink for the next visit—, and the result appears on a live screen that gets the other tables going. You decide the prizes and their odds, you tie the redemption to the consumption you want, and every scan leaves you a contact to invite back. The promotion stops lowering the margin and starts pushing it up.
Design the promotion from the average spend, not the discount, and it will stop being a cost and become a sales lever.
