As Wave is a free online accounting solution – except for the use of card payment options, the payroll feature and the live chat and phone support – there are no coupons or promotions offered whatsoever. However, if you own a business that has at least 11 but not more than 100 employees and you subscribe to the payroll services of Wave, you only have to pay $2 for each of your employee aside from the $15 base fee. Furthermore, if you want live chat and phone support for three months at a discounted price, pay $49 once, and you can save 15%.
