Sella turns every sale into a customer with a name: you know who comes back, who stopped coming and when to invite them. With stamp cards in Google Wallet and Apple Wallet, and no app for your customers to download.
Without a card, every sale is anonymous: the customer pays, leaves and nothing stays with you. With Sella, every answer is in your dashboard:
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.
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.
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.
Every card carries a link to invite a friend. Both get their stamp only when the friend actually buys at your register.
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.
It all happens between two phones: yours and your customer's. You use the dashboard in your browser; your customer uses their wallet.
With their phone camera. They enter their name and save your card to Google Wallet or Apple Wallet. It takes 30 seconds.
Open the dashboard on your phone and scan their card's code. The stamp shows up in their wallet instantly.
When the stamps are complete, the card shows "Reward ready" and they get a notification. They come back to redeem it, and almost always buy something else.
You choose the reward, the number of stamps and the colors. Here are some examples of how it looks in the wallet.
8 themes, 8 illustrated stamps and photos for your type of business, included. With Premium: your counter and club name, your own stamp icon, your photo and rewards along the way.
Google Wallet and Apple Wallet. Nothing to download or remember: the card is always at hand.
Every stamp shows up instantly on their card, with their progress and the reward.
"1 stamp to go", "reward ready", "happy birthday": they arrive as wallet notifications.
Only your business gives stamps, by scanning the customer's card. Everything is logged with date, time and location.
Who comes back, who's cooling off, your peak hours and the effect of each promotion.
Each location with its own QR, and cashiers who only see Register mode. On paid plans.
Set the reward from your dashboard and change it whenever you want. Some ideas that work:

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%.
Sella also works for shopping centers, food districts, merchant associations and trails of partner businesses.
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.
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.
It's the modern version of the cardboard punch card: it lives in your customers' phone wallet (Google 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.
No. They scan your QR with their camera, enter their name and save the card to Google Wallet or Apple Wallet. Alerts (new stamp, reward ready, promotions) arrive in the wallet.
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.
The printed QR is only for joining; stamps are given only by your business, by scanning the customer's card from your dashboard. 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.
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.
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.
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.
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.
Go to your dashboard to stamp, see your customers and send promotions. Your cashiers sign in with their own email.
Your card is in Google Wallet or Apple Wallet. Were you given a business code? Use it here to save your card.
Create your account, design your card with your logo and print your QR in 10 minutes. If you'd rather we do it with you, message us and we'll walk you through it at no cost.
