The subscription was what got me interested. 40 members in the first six weeks. The regulars loved it. But honestly the stamp card caught me off guard too. Works better than I expected.

My customers used to forget their stamp card constantly. Now it's on their phone. That's basically it. They come back more.

I didn't know how many clients weren't coming back until I could actually see it. That was a bit of a wake up call if I'm honest. It's better now.

Furniture isn't something people buy every month so I wasn't sure this made sense for us. But I had a customer come back for a second purchase and she said the message reminded her. That was enough for me.

Nothing frustrated me more than losing clients between appointments and not knowing why. This just keeps me in front of them without me having to do much. Retention is better. I stopped discounting.

People forget you exist between cleans. I use it to stay on their radar. Getting more repeat bookings and a few referrals too which I wasn't expecting.

No. A punch-card app gives a customer a card and stops there. MSTRMND tracks every visit and spend in a live database, rewards customers automatically, and lets you reach the ones who go quiet by push and SMS, or full WhatsApp campaigns once you add Flann. The card is the start. The system is what brings them back.
Never. The loyalty card lives in Apple Wallet or Google Wallet. Customers scan one QR code and add it in under 30 seconds. Nothing to download, nothing to log into.
Flann is your optional AI agent. Once your loyalty system is live, Flann can analyse visit and spend patterns, draft campaigns in your brand voice, and queue them for delivery. You approve with one reply on WhatsApp. The platform runs perfectly without it; Flann just makes it hands-off.
When a customer comes within 100 metres of your location, they get a gentle push on their phone: a nudge to come in, redeem points, or check an offer. (iOS.)
Yes. Upgrade any time; downgrade at your next billing cycle.
You start with a 14-day free trial, full done-for-you setup included, and you're not charged until it ends. If it's not right for you, cancel anytime before day 14 and you won't pay a penny. No forms, no fuss.
No lock-in contract. Cancel any time in your dashboard, or email moe@mstrmnd.co.uk and we do it for you within one working day. On monthly plans your access continues to the end of the current cycle; on annual, to the end of the paid year. No cancellation fees, no exit interviews.
Business plan includes direct Toast POS integration. Any plan works alongside your existing till without integration — staff scan the customer's wallet card with our free scanner app, so nothing about your POS setup needs to change. Square, Clover and Stripe Terminal integrations are on the Q4 roadmap; other POS on request via the Business plan.
We do. Every annual plan includes a 30-minute onboarding call where we design your card, create your first campaign, and train one staff member. You go live within 24 hours of that call. On monthly plans, you can either self-serve using the setup guide (about 20 minutes) or book paid onboarding as a one-off.
You own your customer data. On cancellation you get a full export (CSV) of every customer record, visit, spend, campaign response and consent status — usable in any other CRM or loyalty tool. We keep the data for 30 days after cancellation in case you come back, then permanently delete it. GDPR-compliant, EU-hosted throughout.
No — Flann runs on your existing business WhatsApp number, so customers still see your familiar name. Flann drafts replies and campaigns in your voice; you approve with one tap before anything sends. If you don't have a business WhatsApp yet, we help you provision one during onboarding (free).
