Shared Rewards App vs Your Own Loyalty Program: How to Choose

By Alva Chew · Updated 2026-11-06

In short A coalition loyalty program, the model behind most shared rewards apps, can bring you customers who already hold the app, but you share the rules, the data and the reward cost with other businesses. Your own points program costs you more effort to promote, yet you keep the customer list, set the earn rate and answer to nobody. For a single shop or a small group of outlets, run your own points program first and join a shared app only if the terms are written down.

What is a shared rewards app, and how does it differ from your own program?

A shared rewards app is a coalition loyalty program. Several businesses with different owners join one points scheme, and a customer earns at any partner and spends at any other. The coalition loyalty program entry covers the definition in full.

Your own program is run by you, for your own customers, under your own rules. If you have several outlets, the same balance can work across all of them, which our guide to a loyalty program for multiple outlets explains.

Question	Shared rewards app	Your own program
Who sets the earn rate and reward value	The operator, often with partner input	You
Who pays for a reward	Shared by agreement with the operator	You
Who holds the customer list	Set by the agreement	You
Where customers can spend points	Every partner	Your outlets
Who promotes it	The operator and every partner	You
What happens if the operator changes the rules	You adapt or leave	Not applicable

How big do shared rewards schemes get?

The largest example I could verify is Payback in Germany. The company lists the figures below on its own facts page, so treat them as self-reported.

Payback figure	Value
Active Payback customers in Germany	35 million
Active app users	18 million
Partners, offline, online and mobile	About 700
Incentivized annual revenue across partners, FY 2025	46 billion euro
Collected points redeemed	95%

The scale is the argument for joining a shared app. A customer who already holds the app has a reason to walk into your shop. The scale also has a cost. A coalition of that size is run for its operator and its large partners, and a single café is one of about 700.

What happens when a partner leaves?

Partners can and do leave. In its release on 2025 changes, Payback says the partnership with REWE and Penny came to an end at the end of 2024, and that Edeka and its subsidiary Netto Marken-Discount began partnering with Payback in January 2025.

For a large retailer, leaving means starting a program of its own. A small shop has the same choice in miniature. If a shared app is your only loyalty channel and the operator changes the terms, your customers hold points you no longer control.

What does the research say about coalition programs?

The academic evidence is mixed in a useful way. It supports the idea that coalitions can work and warns that the design decides who benefits.

Paper	Finding	Scope
Shirai, Journal of Services Marketing, 2023	Consumers commonly preferred a coalition program to a single-firm program, more so when the firm was utilitarian-dominant	Two online experiments
Gardete and Lattin, Stanford GSB working paper, 2018	A coalition can benefit every partner if rewards pay more for cross-shopping and cost shares reflect each firm’s contribution	Theoretical model
Stourm and Bradlow, International Journal of Research in Marketing, 2023	Shared points encourage customers to be “promiscuous” across partner stores, and the effect depends on store affinity	Model of multi-store purchases

Two points follow for an owner. Gardete and Lattin’s result depends on cost shares that match each partner’s contribution, and you should ask to see how a shared app splits the bill. Stourm and Bradlow’s word “promiscuous” describes the aim of a coalition, which is to move customers between businesses. That helps you when customers move toward you and costs you when they move away.

What should you ask before joining a shared app?

Get answers in writing for each of these.

What does a reward cost you per US$100 of sales, and who decides when that rate changes?
Do you receive customer names and contact details, or only counts?
Can you leave, and what happens to points customers already hold at your shop?
Is there a monthly fee, a per-transaction fee or a minimum term?
Who else is a partner in your area, and could a competitor sit beside you?

If the operator cannot answer the first two, you are funding rewards for customers you cannot contact.

When does your own program make more sense?

Your own program makes more sense when most of your sales come from repeat customers you can reach yourself. It also fits when your outlets share one owner, because one balance across your branches gives customers the cross-shopping benefit without partners. The first-party data entry explains why a list you collect yourself holds up better than one you rent.

Simplicity matters too. KPMG’s 2019 survey of 18,000 or more consumers in 20 countries found 60% say programs are too hard to join or earn in. Source: KPMG via PR Newswire, 2019. A shared app adds a second set of rules, because customers must learn which partners count and how each rewards them. Our case for points only sets out why one rule, spend and earn, is the easier one to run. Before you commit to either, the guide on whether a loyalty program is worth it shows how to test the numbers for your shop.

Can you use both?

You can, and a few shops do. Treat the shared app as an acquisition channel and your own program as the place where regulars live. Keep the two apart in your books so you can see what each costs per sale. If the shared app’s reward rate is higher than your own, regulars will use it, and you will pay the higher rate on customers you already had.

How Gimify fits

Gimify runs a points program for one business rather than a coalition, with one balance across all your outlets, and customers join by scanning a QR code. The Free plan covers one outlet with unlimited members, and the Unlimited outlets plan is US$99 a month with no per-member or per-location fees.

Questions owners ask

What is a shared rewards app?

It is an app or card that many unrelated businesses join. A customer earns points at one partner and can spend them at another. Researchers call this a coalition loyalty program. A program you run for your own outlets is different, because you are the only owner.

Is a shared rewards app better than my own loyalty program?

It depends on who your customers are. A shared app can introduce you to people who already use it. Your own program gives you control of the rules, the reward cost and the customer list. If you have one shop or a few outlets, your own points program is the simpler place to start.

Who owns the customer data in a shared rewards app?

That is set by the agreement with the operator, so ask before you sign. In your own program, the customer list belongs to your business. Our glossary entry on first-party data explains why that matters.

Can I join a shared app and run my own program?

Yes, nothing stops both, but customers then learn two sets of rules and you pay for rewards in two places. If you try it, decide in advance which program handles which customers and what each one costs per sale.

Do customers prefer coalition programs?

In two online experiments reported by Shirai in 2023, consumers commonly preferred a coalition program to a single-firm program. The abstract gives no sample sizes, and the experiments were not run on small shops.

What happens if a big partner leaves a coalition?

Customers lose places to earn and spend, and the remaining partners lose reach. In Germany, REWE and Penny left the Payback coalition at the end of 2024 and Edeka and Netto joined in January 2025, according to Payback.
