Setting up a digital stamp card: how many stamps is optimal for your industry?

How many stamps should you put on your digital stamp card?

Setting up a digital stamp card takes about fifteen minutes. Deciding how many stamps a customer needs to earn a reward takes a bit more thought. Too few stamps and you are giving discounts to people who would have come back anyway. Too many stamps and customers lose interest before they ever see the reward.

The good news: there are practical rules of thumb for each industry. These are not based on theory but on how customer behaviour actually looks in practice. A regular at a hair salon visits on a different schedule than a regular at a coffee shop. That frequency largely determines how many stamps are realistic.

Below you will find a concrete starting point for each industry, along with the reasoning behind it. That way you can set up a loyalty programme that motivates customers without eating into your margin.

What makes a digital stamp card different from paper

A paper stamp card ends up in a drawer. A digital stamp card lives in your customer's Apple or Google Wallet. That makes a real difference in how customers actually use it.

With paper, customers forget to bring the card. With a digital loyalty card, the card is always in their phone. Customers scan more often, build up their balance faster, and are less likely to drop off. That means you can ask for slightly more stamps with a digital card than with paper, because the barrier to scanning is lower.

That said, the number of stamps is not the only variable. The value of the reward matters just as much. A free treatment worth 60 dollars justifies more stamps than a 5 dollar discount.

The basic formula: reward as a percentage of revenue

Before you pick a number, do a quick calculation first. A solid rule of thumb: the reward should be roughly 5 to 10 percent of the total revenue a customer generates to earn it. Below that range and the card feels worthless. Well above it and you are giving away too much.

Here is an example. Say a haircut at your salon costs 35 dollars and you give away a free haircut after 10 stamps. You are giving away 35 dollars on 350 dollars of revenue. That is 10 percent, which is on the high end but still defensible if the customer would otherwise not come back.

Want to make the reward less costly? Instead of a free treatment, offer a 10 dollar discount. That puts you at 2.9 percent of revenue. Sustainable, but the question is whether customers will find it compelling enough.

| Reward | Revenue at 10 stamps | Percentage | |---|---|---| | Free haircut (35 dollars) | 350 dollars | 10% | | 10 dollar discount | 350 dollars | 2.9% | | Free product (shampoo, 8 dollars) | 350 dollars | 2.3% |

A product as a reward costs you less than a free treatment. Yet it can feel just as attractive to the customer, especially if it is a branded product they would have bought themselves anyway.

Optimal number of stamps by industry

The right number depends on two things: how often a customer comes back and what an average visit is worth. Below are starting points for each industry.

Hair salon and barbershop

Regular clients visit on average every four to six weeks. That is eight to twelve visits a year. A card with 8 to 10 stamps means a customer can earn a reward within a year. That is fast enough to stay motivated.

If you go with 12 stamps, some customers will take more than a year to fill the card. That feels too far away. Eight stamps is a safe starting point for a hair salon.

Nail studio and beauty salon

Clients visit less frequently here than at a hair salon, on average once every three to six weeks depending on the treatment. A card with 8 to 10 stamps works well here too. Treatments are often more expensive, so the reward can be a little more generous.

A beauty salon offering facials at 80 dollars could give a 20 dollar discount after 8 stamps. That is 3.1 percent of revenue. Sustainable and still meaningful to the customer.

Coffee shop and restaurant

Visit frequency is much higher here. A regular at a coffee shop might come in twice a week. A 10 stamp card would be full within five weeks. That can work, but then the reward needs to be modest too, otherwise your margin adds up quickly.

A free coffee after 10 coffees is a classic example. The cost of a coffee is low, the customer feels rewarded, and the card fills up fast. For a restaurant with higher average bills, a card with 5 to 8 stamps and a discount off the next visit works well.

Clothing boutique and jeweller

Here it is less about frequency and more about purchase value. Customers might visit four to eight times a year. A points system works better here than a fixed number of stamps, but if you do use stamps, think about 5 to 6 stamps with a reward that matches the average purchase value.

A jeweller with an average bill of 150 dollars could offer a 25 dollar discount after 6 stamps. That is 2.8 percent of revenue, which is very manageable.

| Industry | Recommended stamps | Type of reward | |---|---|---| | Hair salon / barbershop | 8 to 10 | Free haircut or discount | | Nail studio / beauty salon | 8 to 10 | Discount or free product | | Coffee shop | 8 to 10 | Free drink | | Restaurant | 5 to 8 | Discount off the bill | | Clothing boutique | 5 to 6 | Discount voucher | | Jeweller | 5 to 6 | Discount voucher |

Setting up your stamp card: what else you need to decide

The number of stamps is one choice. There are a few other settings that determine whether your loyalty programme actually works.

An expiry date puts gentle pressure on customers to come back. If you set a card to expire after twelve months, you prevent customers from holding on to a half-filled card for years without returning. At the same time, you do not want loyal customers to lose stamps they have already earned because the window is too short.

A minimum spend per stamp is another option. This stops customers from collecting a stamp on a small purchase where your margin is thin. A coffee shop could set it so a stamp only counts on a purchase of at least 5 dollars.

Finally, make the reward visible. A loyalty card app in the Wallet lets customers see their progress at any time. That is motivating. Customers who know they are two stamps away from a reward are more likely to come back than customers who have no idea where they stand.

Loyalty programme costs: what does it actually cost you?

A digital stamp card has two types of costs. The platform costs, and the value of the rewards you give away.

Platform costs vary. At Beepify you pay a fixed monthly amount depending on the number of active cards. Check the pricing page to see what fits your situation.

You calculate reward costs the way described above. If you are giving away 10 percent of revenue, that only makes sense if customers would come back less often without the card. That is the core of the whole idea: a loyalty programme is not a discount for loyal customers. It is an investment in customers who might otherwise drift away.

A hair salon that loses 60 percent of new clients after a single visit gets more value from a stamp card than one where everyone comes back naturally. Know your own retention numbers and you will know how much a loyalty programme is worth spending on.

Frequently asked questions

How many stamps is a good starting point if I have never used a stamp card before?

Start with 8 stamps and a reward that is easy for you to give, such as a discount or a product. After three months, check how many customers have filled the card. If almost none have, lower the number. If almost everyone is reaching it, raise it.

Can I change the number of stamps partway through?

Yes, but be upfront with your customers about it. Customers with an active card keep their existing terms. New customers get the new setting. That way you avoid frustration.

Is a digital stamp card suitable for small businesses with few customers?

Yes. A digital stamp card works even with just a few dozen customers. You do not need a large database. The card lives in the customer's phone and you simply scan their QR code.

What if customers never redeem their reward?

That might sound like a good thing, but it is actually a sign that the card is not motivating anyone. Customers who never redeem a reward are also customers who are not taking the card seriously. Adjust the threshold or the reward to make it more appealing.

Can I offer more than one type of card, for example a stamp card and a points card?

With Beepify you can set up different card types. A stamp card for frequent visits and a points card for higher-value purchases can run side by side. That works well if you want to reward both regulars and occasional buyers.

Want to try it yourself?

Setting up a digital stamp card with Beepify takes about fifteen minutes. You choose the number of stamps, the reward, and the design. Customers scan a QR code and save the card to their Wallet.
