Why Sella

Built for your business's day to day

Reward consistency

Every class or workout earns a stamp. Ten visits fill up in a few weeks if the member doesn't skip.

See who's drifting away

Anyone who hasn't come in for over 30 days shows up under At-risk customers, and you send a message to their wallet before they cancel.

Bring a friend

Your members invite friends with a link from their card; when the friend comes in, both earn stamps. On every plan.

Illustrative example

How a gym would use it

An example of what day to day could look like with Sella. Not data from a real business.

  1. 1

    The first class

    The member scans the QR code at the front desk and saves the card in Google Wallet, Samsung Wallet or Apple Wallet. On the way in, they get their first stamp.

  2. 2

    On the 5th class

    Their wallet lets them know their protein shake is on the gym.

  3. 3

    Bring a friend

    They share their link from the card; if the friend comes in, both earn a stamp.

  4. 4

    Missed a month

    They show up under At-risk customers and you send: "We saved your spot: your comeback class includes a shake."

Frequently asked questions

What gyms ask

Does it work if I charge a monthly membership?

Yes. The card doesn't replace the membership: it rewards attendance. Every visit earns a stamp and the reward can be a free week or a discount.

How is attendance stamped?

At the front desk, from Register mode: scan the member's card as they come in. There's a 3-minute wait between stamps on the same card to prevent mistakes.

Do my members have to download an app?

No. They scan your QR code with their camera, type their name, and the card is saved in Google Wallet, Samsung Wallet or Apple Wallet. New-stamp and reward-ready alerts arrive right in their wallet.

Does it work for yoga, Pilates or dance studios?

Yes. It works anywhere people come back for classes: you change the name of the stamps (classes, sessions) and the reward.

Can I sell visit passes or monthly memberships?

Yes, with Sella Plus: sell a "10-visit pass" as a pack or the "Monthly membership" as a club, and deduct each visit from Register mode. You charge at your register; Sella only records the balance and the uses.

How much does it cost?

Try Premium free for 30 days, no credit card. Then stay on the Free plan (up to 100 customers) or move to Premium at US$19 a month.

Does it work in my city?

Yes. Sella works in any city or country: everything is online, the card lives on your customers' phones and support is by WhatsApp. Outside Colombia, plans are priced in US dollars.
