Customers love digital receipts

Flux links directly to a customer's banking app so they can pay with their card and go. No more paper waste. A truly contactless transaction.

Amazing, they keep growing and growing, there were just 3 retailers when I joined, now they've got 13 and they've just announced Papa John's too! I use it with Starling with ease. I'm a big supporter of Flux and I'm really excited about their future — it's definitely time to digitse receipts, that's for sure.


Using Flux in conjunction with my Monzo account I have been very impressed with the speed and efficiency of transactions showing a detailed receipt without the need for unnecessary amounts of paper waste! The customer service is always top notch and although I have never had any problems, I have no doubt they would be quickly rectified should the situation ever arises.

Great service you don't even realise what it's doing, it's that simple it automatically attaches receipts has saved me many times I could not find the receipt but I was able to see it in the Monzo app life saver.
