How to Track Coupon & Discount Redemption Rates in Your Restaurant

Why most restaurant discounts lose money

Flat 50% off attracts deal hunters who never return at full price. Without tracking redemption and repeat visits, you cannot tell a profitable promotion from a margin killer.

Indian restaurants running Zomato Gold, in-house coupons, and festival offers simultaneously often double-discount without realizing it.

• Never stack aggregator discounts with in-house coupons
• Set a maximum discount cap (20–30% for most outlets)
• Require minimum order value (e.g., ₹499+) on all coupons
• Limit one coupon per table per visit

How to track redemption rates

Assign unique codes per channel: SWIGGY20, INSTA15, WALKIN10. Log every redemption in your POS or a simple Google Sheet.

Track: codes issued, codes redeemed, average order value with vs without coupon, and repeat visit within 30 days.

• Use POS discount codes, not verbal discounts
• Train staff to enter codes before applying discount
• Review redemption data weekly during active campaigns
• Compare AOV: coupon orders vs full-price orders

Calculating ROI on restaurant coupons

ROI = (Incremental revenue − discount cost − campaign cost) ÷ campaign cost. Incremental revenue means sales you would NOT have got without the coupon.

Example: 100 redemptions × ₹600 AOV = ₹60,000 gross. Minus 20% discount (₹12,000) and ₹2,000 ad spend = ₹46,000 net incremental. ROI = 23:1 if baseline was zero — but adjust for customers who would have come anyway.

• Conservative estimate: 40% of coupon users would have visited anyway
• Track repeat rate at 30 and 60 days post-coupon
• Include staff time and packaging in campaign cost
• Kill campaigns with ROI below 2:1 after 2 weeks

Promotions that actually build loyalty

Birthday offers, "5th visit free appetizer," and referral codes outperform blanket discounts. They reward behaviour you want to repeat.

Promote these on your QR menu footer — DineCard lets you update promotional banners without reprinting.

• Birthday month: 15% off (not 50%) with ID check
• Referral: give ₹100 off to both referrer and friend
• Off-peak: Tuesday lunch 20% off to fill empty seats
• Loyalty punch card: 6th meal free (costs you one dish, not 50% off everything)

Tools for tracking without expensive software

A Google Sheet with date, code, order value, and customer phone is enough for most independent restaurants. Upgrade to POS-integrated loyalty when you exceed 100 coupons/month.

DineCard's digital menu can display current offers — update them in real time when a campaign ends.

• Google Sheet template: 5 columns, review weekly
• WhatsApp broadcast for exclusive codes to regulars
• QR menu banner for active promotions via DineCard
• Monthly ROI review on the 1st of each month
