Design Look:
https://walletbit.com/pos/walletSomething about orange is throwing me off. Green is the color of money. Orange is like a pumpkin. The buttons could be okay but that giant orange bar at the bottom plays tricks on my eyes.
Page addition:
Would strongly recommend adding at least to the bottom of every page in your footer an "about us" page and "contact us" page.
This.
But still the design is delicious.
