What is the best performance management software for a small business?

It depends on what you are actually buying. Effy AI fits teams that want reviews and goals live within a week with no seat minimum and no contract, from $3 per seat per month and free up to 5 users. BambooHR makes sense if you are replacing a whole HR stack, though performance requires the Pro tier at $17 per employee per month. Zoho People is the cheapest credible option outside the US at $3.50 per user per month. Check the vendor minimum before the per-seat price — below 50 people it is the number that decides affordability.
