Yes, you can leave your salary in your UKKO account and pay it later to your own bank account.
In order to be able to accrue pay over a longer period of time and on more than one invoice, your payroll payment option should be selected to withdraw your salary yourself. So, if you want, you can accumulate the total amount of invoices and withdraw your salary later from several invoices at a time.
However, please note that the your salaries will be calculated as soon as the salary can be withdrawn, i.e. when your customer's payment has been logged into our system. This means, that UKKO.fi deducts and calculates your taxes and other mandatory expenses automatically when your customer's payment logs into our system. By delaying the salary payment to your own bank account, you cannot influence on the day when the taxes and other fees are calculated.
