How the Wave vs Stripe calculator works, and how the two compare
Wave is free accounting and invoicing software for small businesses, with pay-per-use payment processing on invoices. Wave's accounting and invoicing are free (Pro plan $19 per month); online invoice payments cost 2.9% + $0.60 per card transaction and 1% for ACH (minimum $1). Stripe is a developer-focused online payments infrastructure company that also sells Terminal card readers for in-person sales. Stripe charges 2.9% + $0.30 for online card payments and 2.7% + $0.05 in person via Stripe Terminal (Reader M2 $59), with no monthly fee and volume discounts on request.
How they are similar: Where they overlap: both Wave and Stripe cover selling online, which is what this calculator compares. Neither requires a monthly subscription on the plans compared here, so your cost scales purely with sales. In both cases the bill is driven by a percentage of each sale plus any fixed per-transaction fee, which is why your average transaction size changes the effective rate as much as the headline percentage does.
How they differ: Only Stripe offers in-person card readers, so that side of the business is not part of this comparison. Wave operates as free software monetized through pay-per-use payment processing on invoices, while Stripe operates as flat-rate card processing with published per-transaction fees. Wave is bookkeeping-first: payments exist to get your invoices paid inside free accounting software, not to power a storefront or point of sale. Stripe is built API-first: it has no storefront or POS software of its own, but offers unmatched flexibility, 135+ currencies, and dozens of payment methods for businesses that build their own checkout.
