I would like to congratulate you on your business. This time, having a creative and imaginative mind is something that a person needs in order to make his business be widely known and successful. We always have to look for innovation and other products or services that the clients need in order to be on the top of our game. We have to have an edge over other companies so that we could garner and have a larger market. And you, having an interest in bitcoin and utilizing it is a nice move for our community.

Having the initiative to make crypto involved in our businesses is a good thing to let people be aware of its existence as well as its benefits. You can help people be curious about it and let them research on their own which is beneficial on their end and could be beneficial to you as well. If you are still looking for suggestions, I suggest for you use the easy payment method through QR via the lightning network so that people would just have to scan and won't undergo the hassle of inputting so many things just to have their payment processed. You could use a static QR for your store in which would serve as the receiver wallet of each of your customers' payments. That way, there would be little to no hassle to both parties.
