Half-price vouchers can fill otherwise empty capacity, but they can also pay a platform to discount customers who already intended to visit. Historical US merchant studies found mixed results: many businesses reported making money, while full-price return visits were uncommon. The lesson for a UAE merchant is not “never discount deeply”; it is to calculate the first-visit loss, the share of buyers who are genuinely new, and the full-price returns needed to recover it.

What did merchants actually report?

In a 2011 survey of 324 US businesses, about 56% said their daily deal made money, 27% said it lost money and 18% broke even, with rounding. About 20% of deal customers returned at full price. Restaurants and bars were less willing than the overall sample to run another deal. A separate Cornell study of US restaurant-deal users found that 44% were already frequent customers of the restaurant, not first-timers.

These are self-reports and consumer research from the US daily-deal boom more than a decade ago—not measured outcomes for UAE merchants today. They do, however, identify what to tag in your own booking and POS data: first visit, prior customer, spend beyond voucher and later full-price visit.

How can a half-price voucher lose money on the first visit?

Use a deliberately illustrative, before-VAT example, not a statement about UAE voucher tax. A Dubai restaurant's normal dinner for two is AED 200 before VAT. A customer buys a voucher for half that amount: AED 100. Suppose a platform retains half of the voucher proceeds—a historical US model discussed in research on Groupon's economics. The restaurant receives AED 50, while food and other per-visit costs are AED 60. It loses AED 10 on the first visit. The same dinner at full price contributes AED 140.

If every voucher buyer is new and comes during otherwise empty capacity, just over 7% would need one later full-price visit to cover those first-visit losses. If 20% are existing customers who would have paid full price, the required full-price return rate among the new buyers rises to about 34%. Those regulars cost the restaurant the AED 140 it would have earned, plus the AED 10 first-visit loss. Additional spend during the voucher visit could improve the result; a full house, extra labour or more regulars could worsen it. The VAT and accounting treatment of real vouchers require advice specific to the offer.

What else did the daily-deal era reveal?

The offer is also an operations test. In research covering US Groupon deals, reviews mentioning Groupon had lower average ratings than other reviews. That finding does not prove the discount caused every poor review, but it warns against releasing more vouchers than staff can serve well. More customers are not valuable if the experience damages repeat business.

An inexpensive channel is not automatically a better one. The economic model of daily-deal platforms cautions that lower platform fees may come with less customer discovery. The same test applies to any platform, DiscGo included: did it deliver customers who would not otherwise have come, and what did those customers contribute?

Decision rule: Cap voucher volume, use it when capacity would otherwise be unsold, tag every buyer as new or existing, and measure spend above the voucher and full-price returns within a defined window. Repeat a deep deal only when the measured extra contribution covers the first-visit loss and discounts taken by existing customers. The historical US results set questions to ask, not UAE benchmarks to copy.
