Stamp Me vs FiveStars (SumUp Connect): Which Actually Fits an Independent Business?

SumUp Connect (FiveStars) is a loyalty layer built on top of SumUp's own POS and payments — Stamp Me runs independently of whatever POS you use. Neither is objectively better; it comes down to whether you want loyalty bundled with your payments vendor or kept separate.

TL;DR: SumUp Connect (FiveStars) is a VC-backed, multi-tenant marketing network acquired by SumUp in 2021 for $317 million. It's built to run on SumUp's own payments hardware, and in exchange for that dependency, it adds customer acquisition through a shared network — your business shows up on nearby customers' screens, not just your own. Stamp Me runs independently of your POS, with flat pricing from $49–$199/month and no shared network. If you already use, or want, SumUp for payments, Connect adds loyalty and network reach on top of that. If you're on a different POS, or don't want your loyalty program tied to your payments vendor, Stamp Me keeps the two separate.

Most "loyalty app comparison" posts stack two feature lists side by side and call it a day. That's not especially useful, because Stamp Me and SumUp Connect aren't really competing on features — they're built on two different business models.

That's the real fork in the road. Everything else in this comparison — pricing, hardware, setup, and customer experience — flows from that one structural difference. Here's how a digital loyalty program for small businesses plays out in practice, and which one actually fits yours.

The Core Difference: Network Marketing Tool vs. Owned Loyalty Program

Connect works like this: a shared touchscreen sits at your checkout counter. When a customer taps in, they're not just joining your loyalty program — they're joining the SumUp Connect network, which cross-promotes them to other (non-competing) local businesses using the same platform. Layered on top is AutoPilot, FiveStars' automated messaging tool that triggers SMS or email promotions such as first-time visits, birthdays, or periods of inactivity.

The upside is real: Connect can expose your business to customers who've never heard of you, because you're borrowing reach from the network. The trade-off is just as real — your reward now competes for attention inside the same app tile as every other business your customer has joined. You're one offer among many.

Stamp Me works the opposite way. It's a single-brand app and NFC/QR presence — customers see your business and only your business. In practice, that means a StampPod (a countertop tap-to-collect device), a Stamp Tag (the same tap-and-go tech, worn by staff for table-side or mobile use), or a join code (a scannable code that adds a customer to your program) — none of which need a POS. There's no competing offers. You get direct access to your own customer data, along with CRM integration and engagement features to act on it.

The honest framing for which independent business loyalty app would work for you: Connect is built for acquisition — bringing in customers you didn't already have. Stamp Me is built for retention — giving the customers who already found you a clear, uncluttered reason to keep coming back instead of drifting to a competitor.

Pricing and Contracts: What You're Actually Signing Up For

This is where the two platforms diverge sharply, and it's often the deciding factor for a small operator working with a fixed budget.

SumUp Connect (FiveStars) doesn't publish pricing — you have to request a demo, and SumUp quotes a custom rate based on hardware and business size. It's typically bundled with SumUp's payment processing (2.6% + 10¢ per in-person transaction) rather than sold standalone. Translation: no price without a sales call.

Stamp Me publishes flat pricing that doesn't move based on transaction volume, customer count, or anything else: $49–$199/month across its Lite, Pro, and Elite tiers, with no long-term contract requirement. Hardware is optional rather than mandatory — one free Stamp Tag is included per location on every plan, and Pro and Elite plans include one free StampPod™ per location (additional pods are $59 each).

For an independent business, that predictability matters as much as the number itself. You know exactly what you're paying for before you commit, and you're not locked into hardware you didn't ask for.

Contract length is the other piece worth knowing before you request that demo. Connect merchants commonly report being on rolling 12-month contracts that auto-renew unless you cancel before the renewal date — so a plan you signed up for a year ago can quietly lock in for another year if the cancellation window slips by. Stamp Me's no-contract structure means there's no renewal date to track in the first place.

The underlying question this section answers: SumUp Connect needs a certain transaction volume or marketing budget to pencil out. If you don't have that volume yet, you're paying network prices — and a network-style commitment — for local-shop economics.

Setup, Hardware, and POS Requirements

SumUp Connect is designed to integrate with your point-of-sale system, with a customer-facing touchscreen provided and installed at checkout. That's a smooth process if you already run a modern POS setup — but it's a real barrier if you don't.

Stamp Me requires none of that. It runs through an app and NFC-enabled devices (or a simple join code), which means it works for businesses without a formal POS system at all. You're not locked into a POS-dependent setup just to run a loyalty program.

In practice, this makes a bigger difference than it sounds like on paper. A small cafe, a pop-up shop, or a salon has a much lower lift getting Stamp Me running than trying to retrofit a Connect kiosk into a setup that was never built around one.

Marketing and Engagement Features: What Each Platform Automates

Connect leans heavily on AutoPilot, its automated marketing engine. Once it's set up, it handles welcome messages for new sign-ups, birthday offers, and win-back campaigns for customers who haven't visited in a while — delivered via app notifications, text, and email. You also get reporting on customer visit and spend behavior.

Stamp Me covers similar ground but keeps it tied to your own brand rather than a network. Rewards can be customized and triggered by a qualifying purchase, a birthday, signing up, a lapsed visit, or even set to trigger randomly as a surprise-and-delight. You get real-time visibility into customer activity, push notifications and SMS for your own promotions, and CRM/EDM integration if you want to run campaigns outside the app.

The practical difference: SumUp Connects' automation comes bundled with — and built around — its shared network. Stamp Me gives you a comparable set of automation tools, but every campaign, offer, and data point stays yours.

Who Each Platform Actually Fits

Rather than the generic "small business vs. enterprise" framing, here's how this plays out in real scenarios:

• A solo cafe, independent salon, or a small business with one or two locations and no dedicated marketing team → Stamp Me. Flat pricing, no POS dependency, and a loyalty experience customers see as yours alone.
• A multi-location retail or restaurant group with a dedicated marketing budget, looking for new-customer acquisition through network exposure → SumUp Connect. The shared network and AutoPilot automation are worth the custom pricing at that scale.

The Bottom Line

Pick SumUp Connect if you're running multiple locations, have a marketing budget to match custom pricing, and want the possibility of new customers through shared network exposure — plus automated marketing you don't have to build yourself.

Pick Stamp Me if you're an independent operator (or a small multi-location business) who wants predictable flat pricing, no POS lock-in, and a loyalty program that's unmistakably yours in the eyes of your customers.

The real choice here isn't retention versus acquisition — it's whether loyalty should live inside your payments provider or run on its own. If you'd rather keep it independent, Stamp Me is built for exactly that.
