iv vs Wave: Invoice Generator Comparison
Wave is a well-established free accounting platform used by millions of small businesses. It includes invoicing, bookkeeping, bank connections, and financial reports in a single product. If you need all of that, Wave is a strong choice.
iv is a focused invoice generator. No accounting, no bank feeds, no financial reports. Just invoices, quotes, and purchase orders. This page compares the two honestly. We make iv, so we have a bias.

When to choose Wave
If you need accounting alongside invoicing — bookkeeping, bank feeds, financial reports, receipt tracking — Wave gives you all of that for free. It is a complete financial platform for small businesses that want everything in one place.
When to choose iv
If you just need to create and send invoices, iv is simpler and faster. No account setup, no accounting concepts, works offline. Freelancers, contractors, and small teams who bill clients and handle accounting separately (or not at all) will find iv more focused.
Frequently asked questions
Is Wave really free?
Wave's invoicing and accounting are free. They make money on payment processing (2.9% + $0.60 per transaction) and payroll services. There are no monthly fees for the core product.
Can iv replace Wave for accounting?
No. iv is an invoice generator, not an accounting platform. If you need bookkeeping, bank reconciliation, or financial reports, Wave or a dedicated accounting tool is the right choice. iv exports to CSV, JSON, XLSX, and QBO/IIF formats for easy handoff to your accounting software.
Does iv work offline?
Yes. iv is local-first and works without an internet connection. Your invoices are stored in your browser. Wave requires an internet connection for all operations.
Does iv support EU e-invoicing?
Yes. iv supports ZUGFeRD, XRechnung, and Factur-X formats for EU e-invoicing compliance. Wave does not currently support EU e-invoicing standards.
