Customer orders and pays the receipt
Customer orders anything from your menu — business as usual. The loyalty program kicks in at payment, when the total receipt amount is known.

Restaurant loyalty program:
$5 = 1 stamp, 5 stamps = bonus
Every $5 in the receipt earns one stamp on the customer’s card. A $25 receipt instantly credits 5 stamps and unlocks the bonus; a $4.50 receipt earns zero. Customer sees the card fill up from real spending — not a dry «$24 of $100» bar.
Built for businesses with variable ticket sizes — restaurants and bistros, bookstores, beauty salons, repair shops. Set the threshold (e.g., $5 per stamp) and the program automatically computes how many stamps to issue for each receipt.

How it works · Stamp collection
How customers collect stamps
Six simple steps — from a receipt to credited stamps. Key difference from classic 5+1: customers can earn multiple stamps in a single scan, depending on the amount.
2
Barista enters amount and generates QR
On their tablet, the barista (or waiter) enters the receipt total — e.g., $12.50. Taps "QR" — the program automatically computes: $12.50 ÷ $5 = 2 stamps (rounded down). A QR appears.
3
Customer scans with camera
Any smartphone camera — Android or iPhone, doesn’t matter. No app to install, no registration required.
4
Returning customer — N stamps instantly
If the customer used your card or any other Costless card before — stamps are credited immediately. Big receipt $25 = +5 stamps, small receipt $4 = 0 stamps (below threshold).
5
New customer — in 10 seconds
First time — customer enters email and instantly gets a magic link. Tap the link — they’re on their card with stamps already credited for this receipt. No forms, no passwords.
6
Card updates live
If the receipt is big and the customer crossed the threshold — they see "Bonus available" immediately. If the amount didn’t reach one stamp (e.g., $3 with $5 threshold) — no stamp credited. The remainder doesn’t accumulate between scans — a deliberate product decision so the math is clear from first glance.
How it works · Bonus redemption
How customers redeem bonuses
Five steps from "I have a bonus!" to "bonus delivered". In simple mode without tiers, the barista just confirms — same as classic 5+1.
1
Customer opens the card with bonus
Customer sees the "Bonus available" indicator on their card, a 4-digit PIN, and a QR. Both valid for one minute or one use. Customer shows the screen to the barista — or just says the PIN.
2
Barista scans the code
On their panel, the barista taps "Issue bonus" and scans the customer’s QR (tablet camera) or enters the 4-digit PIN. In simple mode there’s no tier choice — the barista issues a dish from your menu by the customer’s choice.
3
Screen shows — bonus request
Barista’s screen: "Customer wants the bonus. Confirm or deny?" Quick, no extra detail.
4
Barista confirms
One tap — bonus issued. Customer’s card updates to "Bonus delivered", accumulated stamps are spent on this bonus — and the customer can start collecting the next card immediately.
5
Customer sees confirmation
A second after confirmation — customer sees "Bonus delivered ✓" and a fresh card ready for the next collection. No paper receipts, no waiting.

Who’s already using spend-per-stamp mode
Three verticals with variable ticket sizes where $-per-stamp earns fairer than classic 5+1: customers with bigger receipts earn multiple stamps at once instead of having to come back 5 times.

Flexibility
What you can configure
$-per-stamp mode isn’t a fixed template. Here are 8 key settings you adapt to your average ticket and audience.
| Amount per stamp | The mode’s primary parameter: how much the customer must spend on the receipt to earn one stamp. $5 — typical for a bistro with $10–25 average ticket. $10 — for a bookstore. $15 — for a salon. The bigger the threshold, the fewer stamps per receipt, but each stamp weighs more. |
| Stamps per scan | Receipt amount divides by the stamp threshold, rounded down. Receipt $12 with $5 threshold → 2 stamps. Receipt $4 → 0 stamps (below threshold). The remainder doesn’t accumulate between scans — a deliberate product decision to keep the math clear. |
| Threshold for bonus | 5 stamps — the most popular value. Can be set from 1 to 50: 3+1 for premium items, 10+1 for mass-market. Threshold changes don’t affect already-earned stamps — only new collection. |
| Cap "max stamps per single scan" | Protection against abuse on huge receipts. Receipt $1000 with $5 threshold would theoretically yield 200 stamps — the cap (e.g., 5 per scan) limits it. A single large purchase doesn’t deliver 40 bonuses at once — the customer still has to come back. |
| Anti-fraud protection | Every QR is single-use and lives for a minute. The server recomputes the math from the receipt amount on every scan — even if the customer tries to tamper with the stamp count in the token, they get only what was actually earned by the amount. |
| Single card across the network | If you have multiple branches — customers collect stamps everywhere on a single card. No need for a separate card per location, no manual data transfer. |
| Boosters: birthday + streak | Toggle in campaign settings — no extra tier, no mode switch, no separate campaign. Details in the two sections below. |
| Analytics and export | How many stamps issued, how many bonuses redeemed, average ticket per scan, which customers are most active. CSV export — to share with your manager or accountant. |

Common questions
What people ask before launch
Everything worth knowing about $-per-stamp mode — how to pick a threshold, how it differs from other spend models, rounding behavior.
How does the "$5 = 1 stamp" model work?
You set the threshold — the spend amount per stamp (e.g., $5). At payment, barista enters the receipt total and generates a QR. The program computes automatically: amount divides by threshold, rounded down. Receipt $12.50 ÷ $5 → 2 stamps. Receipt $30 → 5 stamps (or less, if the cap kicks in). Receipt $4 → 0 stamps.
How is this different from plain 5+1 "one visit = one stamp"?
In classic 5+1, one visit always equals one stamp regardless of receipt. A customer with $5 and one with $50 earn equally. With $-per-stamp, a customer with a bigger receipt earns more stamps at once — fairer for businesses with variable ticket sizes (restaurants, bookstores, salons).
How is this different from "cumulative spend" model?
In the cumulative-spend model, the customer sees progress in money: «$50 of $100 to bonus». In «stamp per amount», the customer sees a card with stamps: «3 / 5 stamps». Psychologically the card is stronger — filling-up is visible at a glance, and each stamp is a small win. The business economics of both models are equivalent — the only difference is how it looks to the customer.
How to pick the threshold (amount per stamp)?
Rule of thumb: average ticket ÷ 1.5. If average is $7.50 — optimal threshold ≈ $5 (typical receipt earns 1 stamp, a big $15 receipt earns three). If average is 700 UAH — threshold ≈ 500 UAH.
Does the "Max stamps per single scan" cap apply?
Yes. The cap is applied before crediting. If a customer brings a $200 receipt with $5 threshold — theoretically 40 stamps — but the cap (e.g., 5 per scan) limits it. This protects against abuse on banquet orders.
What about rounding?
Round down. Receipt $9 with $5 threshold → 1 stamp (not 1.8). The remaining $4 doesn’t accumulate between scans — a deliberate product decision to keep the math clear from first glance. No sad messages like "you fell 80¢ short of a stamp".
Can I set $0.50 per stamp?
Technically yes — minimum threshold $0.50. But this makes the program closer to a "discount" than a "loyalty" one. Small thresholds ($1-2) suit businesses with low-margin tickets ($5-10). Big thresholds ($10-50) — for salons, bookstores, restaurants.
