PolishBook keeps the nail record, so the real question is whether you also need the booking, payment and marketing platform wrapped around it.
Most nail software gets judged at the front desk: online booking, deposits, card processing, text reminders. Those are real problems and several products handle them well. PolishBook is built for the part that happens after she sits down, when you need to know she wore a warm nude last time, that it chipped on the free edge at day fourteen, and that her right ring finger is the one you always have to file thin.
The three comparisons below are fit questions, not scorecards. Read each one as: which operator does this product assume you are. A booth renter with sixty regulars, a two chair studio doing structured gel and hand painted art, and a three location group with W2 techs are three different businesses, and the sensible stack is different for each one.
