The right choice depends on your budget and how complex your books are, because all three are strong tools built for different situations. Wave is the practical pick if you want to spend nothing, since its Starter plan handles unlimited invoicing and bookkeeping for free, with a $19 per month Pro tier for automated bank imports [4]. Xero tends to fit product businesses and multi-person teams best because every plan includes unlimited users, and its plans run $25, $55, and $90 per month as you add features like multi-currency and projects [3]. QuickBooks Online is the most widely used option and carries the deepest reporting and the largest accountant and app ecosystem, with plans from $38 to $275 per month, though it caps users by tier and raises prices most years [1][2]. For a freelancer the decision often comes down to Wave versus a low-cost QuickBooks tier, while a growing team with an outside accountant usually weighs Xero against QuickBooks Online [1][3][4].
