If tt is a short-term surplus then they will look for short-term investments such as a deposit account. If it is a long-term surplus then they they consider investment in more assets or consider paying a higher dividend to the shareholders.
If it is a short-term deficit then they will look to see if they can get debtors to pay sooner, or will make arrangements for an overdraft from the bank, or defer buying new assets or paying a dividend. If it is a long-term deficit then they will see if they can cut costs or arrange raising long-term finance.
