Yes, Wave’s accounting, invoice, and receipt-scanning features are completely free. You do have to pay a credit card processing fee for online payments you accept with Payments by Wave, but that’s a standard requirement for all online payments. Wave’s 1% fee for ACH payments and 2.9% + $0.30 fee for credit card charges meets the industry standard. And since Wave doesn’t charge a base fee, the transaction fee is all you’ll ever pay when you use Wave.
