Comparison
Wave is a popular free invoicing-and-accounting tool — but it is primarily focused on the US and Canada, and you have to create an account before you can send anything.
1nvoic3 is invoicing-first and built for the UK. Create a clean, HMRC-ready invoice in under a minute — free, with no signup and no card. Upgrade to Pro (£9.99/mo) only when you want to drop the watermark and unlock premium templates.
We have kept this fair: Wave is a capable free invoicing-and-accounting tool. Where a Wave feature varies by region or plan, we say so rather than guess. Always check Wave's current availability and pricing before deciding.

We would rather point you to the right tool than oversell. If free accounting is what you need, Wave is built for it.
If you are a UK sole trader or freelancer who mainly needs to send professional invoices, yes. Wave is a free invoicing-and-accounting tool that is primarily focused on the US and Canada. 1nvoic3 is invoicing-first and built for the UK, so its invoices are HMRC-ready and you can create one in under a minute with no signup. If you specifically need free double-entry accounting, Wave or a dedicated accounting suite may suit you better.
You don't have to. 1nvoic3 is free to create and download HMRC-ready invoices, with no signup and no card. Free invoices carry a small 1nvoic3 watermark on the PDF, which the Pro plan (£9.99/mo) removes along with unlocking premium templates and custom branding. Many users stay on the free tier indefinitely.
Wave is primarily designed for the US and Canada, and some features such as online payments and payroll are region-limited. If you are invoicing in GBP and want a UK-first, HMRC-ready format without worrying about regional gaps, 1nvoic3 is built for exactly that. Always check Wave's official site for current regional availability.
No. You can create and download an invoice with no signup and no card. You only create a paid plan if you want Pro features like removing the watermark. Wave, by contrast, requires you to create an account first.
Yes — there is nothing to migrate to start. Just open the invoice builder, enter your business and client details, and download a professional invoice. If you upgrade to Pro you can save clients and invoice history for faster reuse next time.
