Wave

Wave (waveapps.com) is a free accounting and invoicing platform built for freelancers, sole traders and very small businesses that do not need — or cannot yet justify paying for — QuickBooks or Xero. The core bookkeeping, invoicing and receipt-scanning tools are genuinely free, with Wave monetising through a paid Pro plan and through payments and payroll processing fees. The catch is scope: Wave is built primarily for the US and Canadian market, and its accounting depth stops well short of what a growing or multi-currency business eventually needs.

Best for

• Freelancers and sole traders who need clean invoicing and basic bookkeeping without a subscription.
• Very small businesses in the US and Canada — Wave's payroll and payments integrations are built specifically for that market.
• Anyone starting out who wants to track income and expenses properly before their volume justifies a paid platform.
• Simple service businesses without inventory, multi-currency billing or complex project accounting needs.

Not ideal for

• Businesses outside the US and Canada — core functionality is available more widely, but payroll and some payments features are not.
• Companies that invoice or hold funds in multiple currencies with any regularity — Wave's multi-currency handling is shallow.
• Businesses that sell physical inventory — Wave's inventory tracking is minimal compared with QuickBooks or Xero.
• Growing businesses that will need a large app ecosystem, advanced reporting or an accountant-facing platform — QuickBooks and Xero have far deeper third-party integration.

Independent verdict

Wave's genuinely free core is the whole pitch, and it holds up: unlimited invoicing, income and expense tracking, basic reporting and receipt scanning cost nothing, which is unusual in a category where "free" almost always means a capped trial. For a freelancer or a one-person service business, that is often literally all the accounting software they need, and paying for QuickBooks or Xero at that stage would be spending money to unlock features they will never touch.

The honest limitation is that Wave was built for a specific segment and does not pretend otherwise. There is no meaningful project accounting, inventory management is thin, multi-currency support does not go deep enough for businesses regularly invoicing overseas clients in their local currency, and the app marketplace is a fraction of what QuickBooks or Xero offer. Wave is a very good product for what it is; it is not a scaled-down version of a bigger platform waiting to be unlocked.

How Wave actually makes money

Wave's core accounting and invoicing stay free indefinitely — there is no feature countdown. Revenue comes from Wave Payments (processing fees on invoice payments and card transactions) and Wave Payroll, a paid add-on. A Wave Pro plan adds features like automatic bank reconciliation and unlimited collaborators for a monthly fee. This is a reasonable model: businesses that never take an online payment or run payroll through Wave can use the core product at no cost indefinitely.

Payroll and geography: the real constraint

Wave Payroll is built for the US and Canada, with different levels of service between the two — in some Canadian provinces and outside North America entirely, payroll is not available or is significantly more limited. Businesses hiring employees outside those markets, or operating primarily outside North America, should confirm exact payroll and payments availability for their region on waveapps.com before assuming Wave covers their needs.

Wave vs QuickBooks and Xero

QuickBooks and Xero cost real money from day one but deliver materially more: deeper multi-currency accounting, proper inventory management, stronger project and job costing, and a large ecosystem of accountant-facing integrations. The sensible way to think about the choice is a growth threshold rather than a feature comparison — Wave is the right tool below that threshold, and the moment a business needs multi-currency invoicing, inventory or an accountant demanding QuickBooks-compatible exports, it is time to migrate.

Verdict

Wave is the best genuinely free accounting and invoicing platform for freelancers and very small North American businesses, and there is little reason not to use it at that stage. Once a business needs multi-currency billing, real inventory tracking or operates mainly outside the US and Canada, plan a move to QuickBooks or Xero rather than trying to stretch Wave beyond its design.
