Wave is free in name but bills $16/mo for the automation most growing businesses end up needing, and the best features only work in the US and Canada. SolidInvoice is open source under MIT, works in any country, and starts at $19/mo cloud with recurring billing, or free if you self-host.

Wave's free tier no longer includes recurring billing, automated reminders, receipt scanning, or auto-import of bank transactions, those moved to the $16/mo Pro plan
Most of Wave's marquee features (Wave Payments, payroll, bank feeds) are restricted to the US and Canada, so customers in the EU, UK, and elsewhere get a much thinner product
Closed-source SaaS, owned by H&R Block, with no self-hosting option and limited control over how your data is stored
Wave bundles accounting with invoicing, which is helpful for some, but unnecessary complexity if you only need professional invoicing
