A great loyalty program drives repeat visits, but vague rules can quietly burn margin. This playbook helps you write a clear, friendly, and abuse‑resistant policy for your digital Stamp program. You’ll set fair rewards, define issuance and redemption rules, configure safe welcome incentives, and use light operational controls in 7stamp—so customers love the value and your team can run it confidently without custom integrations.
Build a margin‑safe reward ladder
Start with reward economics. Estimate your gross margin on the item most customers buy to earn a Stamp. If a latte yields $2.00 margin and you offer the 6th free at a $5.00 retail value, the cost per completion is about $5.00 against five paid visits. Check whether that net cost fits your budget. Cafes often land on “6th coffee free,” while higher‑ticket services, like car washes, lean to “10th wash free.”
Keep it simple: pick a single ladder per Card. If you sell mixed categories, set the reward to a specific product or a clear discount cap. Aim for a completion target customers can reach within four to eight visits. Too short and you invite arbitrage; too long and engagement drops. Review the ladder quarterly and adjust only if your margin or basket mix changes meaningfully.
Issuance and redemption rules that prevent leakage
Issuance rules
Define exactly what earns a Stamp. Set a minimum spend (e.g., “one Stamp per visit on $6+ before tax”) and list eligible items. Exclude gift cards, third‑party delivery fees, and heavily discounted promos. Cap Stamps at one per customer per visit to block receipt splitting. Do not award Stamps on refunds or voids. For split checks, award based on the payer who presents the Card, not every guest at the table.
Redemption rules
Keep redemption clean and consistent. Limit to one reward per transaction. Black out premium add‑ons or limited seasonal items if their margin is tight, and state that taxes and tips are excluded from reward value. Ask the customer to show their Card in Apple Wallet or Google Wallet, then do a quick match to the name on the payment method or a simple verbal confirmation—fast, friendly, and enough to deter misuse.
Safe welcome incentives that don’t invite abuse
Welcome offers accelerate adoption but can be exploited if they’re reusable. In 7stamp, configure a single‑use Smart Voucher linked from your QR or link join flow using Zero Integration. Set a short expiry (7–14 days) and restrict it to first purchase. Alternatively, grant a first‑Stamp bonus on Card add, also with a short expiry. Avoid high‑value freebies; keep the incentive modest so it nudges trial without creating hunters.
Tie the voucher to eligible items and exclude gift cards. If you use Self‑Service Kiosk or Autopilot workflows, still gate the reward with Smart Vouchers so the first benefit is automatically controlled. For events, generate a limited batch of vouchers with a shared expiry window. Communicate “one per customer” clearly on signage and the Card description.
Operational controls to keep the program honest
At checkout, use Staff Scanner to validate Stamps quickly. This adds a lightweight human check and prevents self‑issued Stamps on ineligible purchases. For rewards, require a Redeem Code at the counter so staff must enter or scan it before the reward applies. Rotate Redeem Codes every 30–60 days or when staff or shifts change, and store codes where only authorized team members can access them.
Choose workflows that fit your control level: Staff Scanner and Receipt QR emphasize validation; Self‑Service Kiosk and Autopilot prioritize speed. You can also accelerate tap‑to‑present with Apple VAS and Google Smart Tap on compatible NFC readers, but they’re optional. If the network is down, log Stamps manually and apply them via Staff Scanner later—note the customer’s name and last four digits of their phone for reconciliation.
Refunds, exceptions, and multi‑location consistency
Document how you reverse Stamps fairly. On a full refund, remove the most recent Stamp tied to that visit or void the associated reward if it was redeemed. On exchanges, keep Stamps if value is equal or greater; otherwise, reverse one Stamp. For partial refunds, leave Stamps unless the minimum spend drops below eligibility—then remove one. Train staff to explain the why briefly and offer a polite make‑good only when store error caused confusion.
For multi‑location operators, publish the same policy across sites and keep scripts identical. Use location‑specific signage (address or store name) so customers know they’re in the right place, but don’t vary core rules by store unless pricing and margins differ significantly. Limit staff access to Redeem Codes by role, keep a shared policy doc, and align rotation dates so teams change codes at the same time.
Monitor, communicate, and train
Set a weekly 10‑minute review. Look for unusual spikes in Stamps issued by shift, outsized clusters of redemptions from the same device pattern, or many first‑day completions. Keep a simple incident log: date, store, what happened, action taken. If abuse appears, tighten rules (shorter voucher expiry, stricter item eligibility). When trends stabilize, consider loosening slightly for customer friendliness.
Keep customer messaging concise and visible. On the Card, include the ladder (“Get 1 Stamp per $6+, 6th coffee free”), core exclusions, and a link to the full policy. Add in‑store signage near the QR join point. Use multilingual mode to show the Card and messages in the customer’s preferred language—7stamp supports 54 languages—so rules are understood without staff translating on the spot.
- Invite: “Scan this QR to add your Card—no app, just Apple Wallet or Google Wallet.”
- Earn: “One Stamp today since your total is over $6, and it’s one Stamp per visit.”
- Redeem: “You’ve reached your free drink. I’ll enter our Redeem Code and apply it—tax and tip not included.”
- Edge case: “This voucher looks expired. I can still honor 10% off today, and you’ll start earning Stamps for next time.”
Refresh training quarterly. Role‑play quick ID checks, how to decline a second reward politely, and what to do if someone presents screenshots or a duplicated Card. Reinforce that consistency beats discretion—staff follow the script, managers handle exceptions. With clear rules, light controls, and friendly messaging, your Stamp program stays generous for loyal guests and sustainable for your margins.
