Wave

Wave is the answer to a simple question: what if proper accounting software was just free? For sole traders, freelancers and micro-businesses, Wave offers genuinely capable invoicing and double-entry bookkeeping at no cost, with no trial clock ticking and no artificial crippling of the free tier. It makes its money instead on payment processing and payroll, which you only pay for if you use them. In this review I look at what you get for free, how Wave earns its keep, what the paid options cost in 2026, and where its limits lie.

The short version: Wave is our pick for the best free accounting software. Its core invoicing and accounting are genuinely free and genuinely useful, making it ideal for sole traders and side hustles that cannot justify a monthly subscription. It has fewer advanced features than the paid platforms, no inventory, and limited support on the free tier — but for a small, simple business, it may be all the accounting software you ever need.

Wave at a glance

Genuinely free accounting

Wave’s headline is that its core is free, and it is worth stressing how real that is. This is not a stripped-back teaser designed to push you to upgrade within a fortnight. Wave gives you unlimited professional invoicing, unlimited expense and income tracking, and proper double-entry accounting with the standard financial reports — permanently, for nothing. For a freelancer, a sole trader or a very small business, that covers the essentials of running the books completely. In a market where rivals charge $20 to $99 a month, a genuinely free, genuinely capable option is remarkable, and it is the whole reason to choose Wave.

The free plan does the fundamental jobs well: create and send branded invoices, record what you spend and earn, categorise transactions, and produce the reports you need for tax and to understand your business. For a micro-business whose finances are relatively simple, there is little that a paid tool would add that they would actually use — which makes paying for one hard to justify when Wave does the job for free.

Invoicing and everyday use

Wave’s invoicing is its strongest feature and genuinely competitive with paid tools. You can create clean, professional, branded invoices, set them to recur, and — if you enable Wave Payments — let customers pay online by card or bank transfer directly from the invoice. You can track which invoices are outstanding, viewed and paid, and send reminders. For a freelancer whose main financial need is simply to bill clients and get paid, Wave’s free invoicing handles that beautifully. The everyday experience of recording income and expenses and keeping the books tidy is straightforward and clean.

How Wave makes money: payments and payroll

Free software has to be paid for somehow, and Wave’s model is refreshingly honest: it charges for the things that genuinely cost money to provide. Wave Payments lets your customers pay invoices online for a standard per-transaction processing fee, the same way any payment processor charges — you only pay when you actually get paid, and it is optional. Wave Payroll is a paid add-on (in the US and Canada) that runs pay for your employees for a monthly fee plus a per-employee charge. Because these are usage-based and optional, you are never paying a subscription for features you do not use — a fair, transparent approach that suits a cost-conscious small business well.

There is also an optional Pro plan, a low monthly fee that adds conveniences to the free tier — automatic bank-transaction import (rather than manual entry), recurring invoicing, receipt capture and the removal of ads. For a slightly busier small business, that modest cost buys real time savings, but it remains entirely optional; the free Starter tier stands on its own.

Plans and pricing

Wave keeps things simple: a free Starter tier, an optional low-cost Pro tier for automation, and usage-based payments and payroll on top. There is no complex ladder of subscriptions to decode.

The maths is easy: if you just need invoicing and bookkeeping, Starter costs nothing. If you want automatic bank imports and receipt capture, Pro adds them cheaply. If you take card payments or run payroll, you pay the standard processing or payroll fees only for what you use. For a sole trader or micro-business, the total cost of running Wave is typically far lower than any subscription rival, and often zero.

Ease of use and its limits

Wave is clean and easy to use, with a simple, uncluttered interface that suits its non-expert audience — you do not need to be an accountant to keep your books in it. The trade-off for being free and simple is a shorter feature list. There is no inventory management, the range of integrations is limited compared with QuickBooks or Xero, advanced reporting is basic, and support on the free tier is limited (paid features get more direct help). None of these matter for a simple service business, but a growing or product-based business will bump into the ceiling — at which point moving to a paid platform makes sense. Wave is honest about being the right tool for the smaller end of the market.

Who Wave is for

Choose Wave if you are a sole trader, freelancer or micro-business that wants proper invoicing and accounting without paying a monthly subscription — it is our pick for the best free accounting software. It is ideal for side hustles, new businesses finding their feet, and anyone whose finances are simple enough that a paid tool would be overkill.

Look elsewhere if you need inventory, deep features or lots of integrations (QuickBooks), unlimited users and best-in-class reconciliation (Xero), the most polished freelancer invoicing (FreshBooks), or a paid tool with a free plan that scales further (Zoho Books). Compare them all on our best accounting software of 2026 list.

Getting started with Wave

Getting started with Wave costs nothing and takes minutes. You create an account, add your business details and logo, and you can send your first invoice straight away. On the free Starter tier you import bank transactions manually (or upgrade to Pro for automatic imports), categorise your income and expenses, and your books build up from there. There is no trial to expire and no credit card required to begin. For a freelancer or new business owner who has been putting off sorting out their finances because software felt expensive or complicated, Wave removes both barriers at once, which is exactly its appeal.

Receipts and the Pro features

For a small monthly fee, Wave’s Pro plan adds the conveniences that save the most time. Automatic bank-transaction import means you no longer key entries in by hand; recurring invoicing handles repeat billing automatically; and receipt capture lets you photograph a receipt and have Wave pull out the details and file it against an expense. These are the features that turn Wave from a manual free tool into something closer to the paid platforms’ automation, at a fraction of their cost. For a busier micro-business, the modest Pro fee quickly pays for itself in time saved — but it stays optional, so you upgrade only if and when you need it.

Tax time with Wave

Where Wave really proves its worth is at tax time. Because it keeps proper double-entry books and produces the standard financial statements, your income, expenses and profit are already organised when you need them — no scrambling through bank statements and shoeboxes of receipts. You can run a profit-and-loss report for the year, hand tidy figures to an accountant, or use them to file yourself, all from software that cost you nothing. For a sole trader who dreads tax season, having a year’s finances already in order, for free, is a genuine relief and one of the strongest reasons to keep the books in Wave throughout the year.

Wave versus the paid platforms

Wave’s honest position is that it is the best free option, not the most powerful option. Against QuickBooks, Xero, FreshBooks and Zoho Books it gives up advanced features, inventory, deep reporting, broad integrations and (on the free tier) prompt support. What it offers in return is simple: genuinely capable invoicing and accounting at no cost. For a micro-business whose needs are basic, that trade is overwhelmingly in Wave’s favour — why pay $20-99 a month for capability you will not use? For a growing or product-based business, the paid platforms are worth their cost. Wave knows its lane and serves it better than anyone.

Who should upgrade from Wave

Wave is ideal until your business outgrows it, and it is worth recognising when that happens. If you start needing inventory management, project profitability, deeper or customisable reporting, lots of third-party integrations, multiple team members with different permissions, or prompt hands-on support, you have reached Wave’s ceiling — and that is a sign of healthy growth rather than a failing of the software. At that point, migrating to Xero, QuickBooks or Zoho Books is a sensible investment. But many sole traders and micro-businesses never hit that ceiling at all, and for them Wave remains all the accounting software they will ever need.

Security and your data

Despite being free, Wave applies proper security to your financial data, using encryption, secure data centres and regular backups, and it is a established company (part of a larger financial-software group) rather than a fly-by-night free app. Your records live safely in the cloud, accessible from anywhere and protected against the loss you would risk keeping everything on one computer. Given how sensitive financial information is, it is reasonable to ask how a free product handles it — and Wave’s answer, funding itself through payments and payroll rather than by compromising your data, is a sound and transparent one.

Is Wave worth it in 2026?

For its audience, Wave is emphatically worth it — because for many it costs nothing. If you are a freelancer, sole trader or micro-business with straightforward finances, Wave gives you professional invoicing and proper double-entry accounting for free, with fair, usage-based charges only for payments and payroll if you choose to use them. It will not suit a growing, product-based or complex business, and its free support is limited, but those are reasonable limits for a free product. In a market where good accounting software usually costs real money every month, Wave’s genuinely free, genuinely capable offering is remarkable, and it remains the best free accounting software you can get.

Wave for invoicing-only users

Many people come to Wave needing just one thing: a free way to send professional invoices and get paid. On that narrow but common requirement, Wave excels. You can create unlimited branded invoices, set up recurring ones, accept online payments, and track what is outstanding — all without paying a subscription. For a freelancer or side-hustler whose accounting needs really are that simple, Wave works beautifully as, in effect, free invoicing software, with proper bookkeeping quietly building up in the background whether you engage with it or not. It is one of the easiest ways to look professional and get paid without spending a cent.

Wave Payments in detail

Wave Payments is how many users happily fund an otherwise free service, and it works like any standard payment processor. Customers can pay invoices online by credit or debit card, or by bank transfer where available, and Wave charges a standard per-transaction fee for processing — you only ever pay when you actually receive money. Payments are recorded and reconciled against the invoice automatically, keeping your books accurate. The rates are in line with typical processors, and because it is built in, the experience is seamless. For a small business, paying a normal processing fee only on money you have received is a fair, predictable cost.

Wave’s mobile app

Wave offers mobile apps that cover the essentials for a business owner on the move: creating and sending invoices, seeing which have been paid, and capturing receipts by photographing them. For a freelancer who is often out with clients or on site, being able to raise an invoice the moment a job is done — rather than waiting until back at a desk — helps the cash come in faster. The apps are not as deep as the full web experience, but they cover the tasks that most need doing away from the computer, which is exactly what a micro-business wants from mobile.

Common questions about the free model

A reasonable instinct with free software is to ask where the catch is, so it is worth being clear. Wave’s core accounting and invoicing are free permanently, not for a trial period, and the company makes its money from optional payment processing and payroll rather than from your data. There are no artificial limits designed to force an upgrade — you can run a whole small business’s books on the free tier indefinitely. The genuine trade-offs are simply fewer advanced features and limited support on the free plan, which is a fair exchange. For a sole trader or micro-business, there really is no catch worth worrying about.

The verdict

Wave is proof that good accounting software does not have to cost anything. Its free tier delivers genuinely capable invoicing and double-entry bookkeeping with no catch, its paid options are fair and usage-based, and for a sole trader or micro-business it can cover every financial need at little or no cost. It lacks inventory, deep features and broad integrations, and its free support is limited — but for its intended audience those gaps rarely matter.

If your business is growing, product-based, or needs advanced features, one of the paid platforms is the right investment. But if you are small, simple and budget-conscious, Wave is the one I recommend — the best free accounting software there is, and often all a micro-business will ever need.
