Digital stamp card for your business A card your customers carry. A dashboard that tells you who comes back.

Sella connects both sides: the stamp card in their phone's wallet and your business's charts.

The data you're missing

Six questions you can't answer today

Without a card, every sale is anonymous: the customer pays, leaves and nothing stays with you. With Sella, every answer is in your dashboard:

How many of your customers come back?Sella shows you how many return and how often, no guessing.
Who stopped coming?A customer who leaves doesn't tell you. Sella shows who hasn't been back in over 30 days, by name.
What day and time is your business empty?Your peak hours and slow days, from your customers' real visits.
Who are your best customers?How many times each one came, how close they are to their reward and when their birthday is.
Who do you message to bring them back?Without a name or contact you can't invite them. With Sella a notice reaches their phone.
Did your last promotion work?72 hours later you see how many came back and how much extra you sold.

What Sella does for you

It doesn't just keep stamps: it tells you what to do so they come back

A dashboard full of charts doesn't tell you what to do on Friday. Sella combines your data, what you told us about your business and the local calendar, and suggests one concrete action.

One recommendation at a time, with the why

Sella looks at who stopped coming, your slow days, paydays, holidays and even national-team matches. It suggests what to send, to whom and when; you review and schedule it.

  • The message comes written, in your business's tone
  • It never suggests what you said you don't do (like % discounts)
  • It goes out the day and time you choose
Results in money

72 hours later, you know if it worked

We compare with the same hours in previous weeks, so we don't count what would have happened anyway. You see how many came back and how much extra you sold.

  • How many invited customers came back
  • Visits vs. a normal week
  • What Sella brought you this month vs. what it costs
Bring a friend

Your customers bring you customers

Every card carries a link to invite a friend. Both get their stamp only when the friend actually buys at your register.

  • You choose the gift and the monthly cap
  • No cheating: no self-invites or repeated phones
  • We let the inviter know when their friend arrives
First steps

Ready in 10 minutes, no marketing skills needed

We guide you in order: tell us about your business, we suggest the reward based on what your customer spends, you print your QR and give yourself the first stamp.

  • We tell you what each reward costs you
  • If you prefer, we do it with you on WhatsApp
  • Your customers download nothing

What your customers see

A card with your brand, for every kind of business

You choose the reward, the number of stamps, the theme and the background. Here are some examples of how it looks in the wallet.

Your logo, 8 themes and photos for your type of business, included. With Premium: your counter and club name, illustrated stamps or your own icon, your photo and rewards along the way.

Features

Everything you need, nothing you don't

It lives in the wallet

Google Wallet, Samsung Wallet and Apple Wallet. Nothing to download or remember: the card is always at hand.

Bring a friend

Your customers invite friends with a link from their card; when the friend buys, both earn stamps. On every plan; you turn it on.

It notifies them for you

"1 stamp to go", "reward ready", "happy birthday": they arrive as wallet notifications.

Controlled stamping

Only your business gives stamps, by scanning the customer's card (or with a one-time delivery code). Everything is logged with date, time and location.

Analytics that mean something

Who comes back, who's cooling off, your peak hours and the effect of each promotion.

Locations and cashiers

Each location with its own QR, and cashiers who only see Register mode. On paid plans.

Rewards along the way

Up to 2 small rewards before the final one, with their text inside the stamp, so nobody drops the card. On paid plans.

Delivery orders count too

One-time codes to stick on each bag: the customer adds their stamp from the card. On paid plans.

More Google reviews

After redeeming a reward, the wallet asks for a review: everyone equally, no incentives, at most every 90 days. You just paste your Google link. On paid plans.

Your reward, your rules

You decide what to give and when

Set the reward from your dashboard and change it whenever you want. Some ideas that work:

Coffee shop or bakeryBuy 8 drinks, the 9th is free
Barbershop or salon5 cuts, the 6th half price
Restaurant10 visits and dessert is on the house
Store8 purchases and 20% off the next one
Giving away 1 in 9 coffees is about an 11% discount: cheaper than any advertising, and you only "pay" it once the customer has already bought from you 8 times.

How does the customer limit work? It counts the people with a card at your business. At the limit, your current customers keep stamping normally; new ones can join once you upgrade. We warn you from 80%. Paying quarterly or semiannually saves you 10% or 15%.

For business groups

Managing many stores?

Sella also works for shopping centers, food districts, merchant associations and trails of partner businesses.

Shopping centers

One card for the whole center. Every purchase at a store adds a verified visit, and you see who comes back, which stores they go to and what they combine.

  • Visitor, Regular and VIP tiers
  • Parking as a loyalty reward
  • Monthly AI report per store
See plans for shopping centers

Passports and trails

Bring the neighborhood's coffee shops or a district's restaurants together on one card: the customer visits each one and, on completing the trail, wins a big reward.

  • Each business keeps its own card
  • Everyone gets new customers
  • Ready in a week

FAQ

What people ask us most

What is a digital loyalty card?

It's the modern version of the cardboard punch card: it lives in your customers' phone wallet (Google Wallet, Samsung Wallet or Apple Wallet), never gets lost and is stamped by scanning a code. When it's complete, the customer sees "Reward ready" and gets a notification.

Do my customers need to download an app?

No. They scan your QR with their camera, enter their name and save the card to Google Wallet, Samsung Wallet or Apple Wallet. Alerts (new stamp, reward ready, promotions) arrive in the wallet.

Do I need to buy any equipment?

No. Everything works with the phone you already have: open the dashboard in your browser and scan the customer's card code to stamp. No terminals, no readers.

How does Sella prevent stamp fraud?

The printed QR is only for joining; stamps are given only by your business, by scanning the customer's card from your dashboard (or with a one-time delivery code you hand out). The same card can't be stamped twice within a few minutes, each reward is handed over only once (even if the button is tapped twice), and everything is logged with date, time and location.

What if my customer completes the card and doesn't claim the reward?

It's saved on their card as "Reward to claim" and they keep collecting stamps toward the next one. You decide whether it's given with the purchase that completes the card or on the next visit, and whether it expires.

Can I give a reward before the card is complete?

Yes, with Premium: up to 2 rewards along the way (for example, "20% OFF" at stamp 4 of 8). They show inside the card with a star and, when they reach that stamp, the customer earns it; at the register you apply it to that purchase or save it.

What happens when the 30-day trial ends?

You choose: pay for the plan you need or stay on Free, without losing your card or your customers (up to 100). We don't ask for a credit card for the trial, so there are no automatic charges.

I have several locations or cashiers. Does it work for me?

Yes. With Premium you create up to 5 locations (15 on Large business), each with its own QR, and cashier accounts that only see Register mode. You decide whether stamps are shared across locations or each location keeps its own card.

How long until it's up and running?

About 10 minutes: create your account, set the reward and number of stamps, print your QR and you're done. If you prefer, we'll walk you through it on WhatsApp at no cost.
