Integrated Crypto Payments Feature

Some companies are already accepting crypto payments against the background of fast crypto adoption around the globe. But mutual crypto settlements can be complicated to implement.

The second vital point here is the anonymous nature of crypto transactions, which is good for sure, but it may go against accounting regulations.

However, the question of how one can directly link blockchain transactions to a real deal will arise soon enough. This is where Kassa joins in, because our platform connects crypto transactions and the entire transaction documentation.

The price can significantly vary in sync with the number of features you want to have, so any figure without studying your specifics may be misleading.
