the account will be received the next day, and it will be transferred to next Monday every weekend, that is, the business expenses on Friday will be received on next Monday together with Saturday and Sunday, and the same is true for holidays. \xd\ Merchants with installed machines must keep the credit card transaction documents (keep them for one to two years).
