Wave Review UK 2026: In-Depth Analysis

Wave is a free cloud bookkeeping and invoicing platform built in Toronto and now owned by H&R Block. It is one of the few genuinely free accounting tools on the market, with unlimited invoicing, expense tracking and basic profit and loss reporting available on the Starter plan. For UK readers, however, the picture is mixed. Wave is designed around the United States and Canadian markets, it is not recognised by HMRC for Making Tax Digital, and several core features (payroll, payment processing, advanced bank feeds) are limited or unavailable outside North America. This review explains exactly what Wave does well, where it falls short for British users, and which UK alternatives fit better if your needs go beyond invoicing.

Quick verdict

• Best for: UK sole traders trading below the VAT registration threshold who want a free, no-frills tool to send invoices and log income and expenses.
• Not for: VAT-registered businesses, limited companies that need MTD-ready filing, or anyone who needs UK payroll, CIS or Self Assessment integration.
• Headline price: Free Starter plan, with a Pro tier at roughly £12 per month for receipt scanning, automated reminders and reduced payment fees (UK pricing is presented in US dollars and converted at checkout).
• MTD status: Not MTD-compatible. Wave does not file VAT returns to HMRC and is not on HMRC’s recognised software list.
• Deployment: Cloud only, with iOS and Android apps for invoicing.
• Country focus: Primarily United States and Canada; usable in the UK with significant caveats.

What is Wave?

Wave was founded in 2010 in Toronto, Canada, with a deliberately disruptive pricing model: free core accounting software, monetised through paid add-ons such as payment processing, payroll and advisor services. The product gained millions of users across North America and was acquired by H&R Block, the US tax preparation company, in 2019. Since the acquisition, H&R Block has tightened the integration between Wave and its tax services in the United States, and in 2024 introduced a paid Pro tier alongside the free Starter plan.

Wave is cloud-native, runs in any modern browser, and offers companion mobile apps for invoicing on the go. Its target customer is a sole proprietor, freelancer or single-owner micro-business in the US or Canada, typically without employees and without complex tax obligations. Wave’s marketing emphasises ease of use and a clean interface, and these are the areas where it consistently rates well in user reviews on G2 and Capterra.

In the UK, Wave occupies an unusual position. There is no UK-specific edition of the product, no UK support team, and no integration with HMRC. British users sign up to the same product as US and Canadian customers, with currency settings adjusted at the company profile stage. This means UK sole traders can technically use Wave for invoicing in pounds sterling, but features that depend on country-specific tax authorities (payroll filings, sales tax automation, payment processing) either do not work or are not available outside North America.

Pricing breakdown

Wave operates a two-tier subscription model, with usage-based fees layered on top for payment processing.

Plan	Monthly price (approx GBP)	What is included
Starter	Free	Unlimited invoicing, estimates, customer and vendor records, manual expense tracking, basic income and expense reports, single user
Pro	Around £12/month (billed in USD, approx $16)	Everything in Starter plus automatic bank import, receipt scanning, automated late payment reminders, unlimited receipt uploads, reduced credit card processing fees in the US and Canada

Add-on fees that may apply:

• Wave Payments: US and Canada only. UK businesses cannot accept card payments through Wave’s native processor and must use a third-party Stripe or PayPal link instead.
• Wave Payroll: US and Canada only. There is no UK payroll module.
• Wave Advisors: US-based bookkeeping coaching service, not relevant for UK users.

Worked example for a UK sole trader. A self-employed graphic designer turning over £35,000 a year, working alone, sending around 15 invoices a month and tracking expenses manually could run their entire bookkeeping on the free Starter plan at no cost. They would, however, need to handle payment collection through a separate Stripe account or bank transfer, and they would have to file their Self Assessment return outside Wave because the platform has no UK tax integration. If they upgraded to Pro to get receipt scanning and bank import, the cost would be around £144 a year. By comparison, FreeAgent at £19 per month including UK Self Assessment filing comes to £228 a year, and Pandle’s free tier offers MTD-ready VAT support at no cost. The pricing gap narrows quickly once you factor in features Wave simply does not offer in the UK.

Core features in depth

Invoicing

Invoicing is Wave’s strongest feature and the area most relevant for UK users. The invoice builder is clean, supports custom logos and colours, and lets you save line items as products for reuse. You can set payment terms, add taxes (configurable for UK VAT rates manually, although there is no automatic UK VAT logic), and send invoices directly from the platform with a built-in pay-online button. Recurring invoices are supported on both Starter and Pro, and Pro adds automated late payment reminders.

Wave’s invoice templates are well designed and look professional out of the box, which is a real advantage for sole traders who do not want to spend time on document design. Estimates can be converted to invoices in one click, and customers receive a hosted invoice page rather than a PDF attachment, which makes it easier for them to pay or query items.

Expense tracking

Expense tracking on Starter is manual: you enter transactions one at a time, categorise them against an expense account, and attach a receipt image if you wish. Pro unlocks automatic bank feeds, although in the UK these are powered through a US-focused aggregator and bank coverage is patchy. Major UK high street banks may connect, but smaller banks, building societies and many newer challenger banks often do not. This is a significant practical limitation: in the UK, FreeAgent, Xero and QuickBooks all have direct Open Banking feeds with reliable coverage, while Wave relies on third-party screen scraping that can break frequently.

Receipt scanning on Pro lets you photograph receipts on the mobile app and have them parsed into expense entries. Accuracy is reasonable for clearly printed receipts in English but not as polished as Dext, AutoEntry or Hubdoc.

Reporting

Wave produces the standard small business reports: profit and loss, balance sheet, cash flow, sales tax report, customer statements, aged receivables and aged payables. Reports are exportable to CSV and PDF. They are functional and adequate for a sole trader keeping basic books, but they are not designed around UK accounting conventions and there is no way to produce SA103 self-employment pages or UK Corporation Tax filings from within the product.

Payments

Wave Payments is not available in the United Kingdom. UK users wanting to accept card payments through their Wave invoices must add a manual link to a Stripe Checkout, PayPal.me or other third-party page. There is no native integration that records the payment automatically against the invoice, so reconciliation has to be done by hand.

What Wave does not include

For UK users the gaps are significant: no MTD VAT submission, no Self Assessment integration, no UK payroll, no CIS, no IR35 tooling, no UK pension auto-enrolment, no Companies House filing, no Corporation Tax computation, no automatic UK VAT scheme handling (standard, flat rate, cash accounting), no postponed VAT accounting on imports. None of these are mentioned in Wave’s feature list because the product is not built for the UK market.

MTD and HMRC compliance

This is the single most important section for any UK reader, and the answer is straightforward: Wave is not MTD-compatible. Wave does not appear on HMRC’s list of software recognised for Making Tax Digital for VAT, and it has no submission API connection to HMRC. The product cannot file VAT returns, cannot meet the digital links requirement, and is not registered as an MTD bridging tool either.

For VAT-registered UK businesses, this means Wave on its own is not a legally compliant solution. If you are above the £90,000 VAT registration threshold, or you have voluntarily registered for VAT, you must keep digital records and file through MTD-compatible software. Using Wave alone would not satisfy this obligation. In theory you could export data from Wave into a separate bridging tool such as Tax Optimiser or 123 Sheets, but this introduces a manual step, breaks the digital links requirement if not done carefully, and adds cost on top of the bridging subscription.

For Making Tax Digital for Income Tax Self Assessment (MTD ITSA), which begins phasing in from April 2026 for self-employed individuals and landlords with qualifying income above £50,000, Wave is also not on HMRC’s recognised software list. Sole traders who fall within scope of MTD ITSA cannot rely on Wave for quarterly submissions.

The practical consequence: if you are a UK sole trader below the VAT threshold and outside the MTD ITSA income brackets, Wave is legally usable as a bookkeeping tool, although you will still file your Self Assessment manually through HMRC’s online portal or third-party tax software. As soon as you cross any MTD threshold, Wave stops being viable as your primary record-keeping system.

Integrations

Wave’s third-party integration ecosystem is notably thin and heavily skewed towards North America. The platform exposes a limited public API but does not have a managed app marketplace in the style of Xero or QuickBooks Online.

• Bank feeds: Available on Pro, but UK bank coverage is unreliable. Open Banking is not used; feeds run through a US aggregator.
• Payment processors: Stripe and PayPal can be added manually as payment links on invoices; there is no native two-way sync.
• E-commerce: No direct integration with Shopify, WooCommerce or Etsy in the UK, although Zapier can be used to push order data in.
• Receipt capture: Built-in scanning on Pro; no native Dext, AutoEntry or Hubdoc connector.
• Payroll: None in the UK.
• CRM and project management: No native connectors; Zapier is the only practical bridge.
• Accountant tools: No advisor portal designed for UK practices, no IRIS, TaxCalc, BTCSoftware or Capium connection.

By contrast, Xero lists more than 1,000 UK app integrations and QuickBooks Online has hundreds, including UK payroll, CIS and pension specialists. Wave’s ecosystem cannot compete in the UK on this front, and most British accountants will not have come across the product in practice.

Pros

• Genuinely free Starter plan. Unlimited invoices, estimates, customers, vendors and basic reports at no cost is a real, not freemium, offering. There is no invoice cap or trial period.
• Clean, modern interface. Wave’s design is one of the most user-friendly in the small business accounting space, and the learning curve is short for users without a bookkeeping background.
• Professional invoice templates. Out-of-the-box invoices look polished and customisable, which matters for freelancers presenting work to clients.
• Multi-business on one login. You can run several separate businesses under one Wave account at no extra cost, useful for sole traders with side projects.
• Mobile invoicing app. iOS and Android apps allow on-the-go invoicing and basic expense entry, which is helpful for tradespeople and field-based freelancers.
• No user limit on Pro. Pro plans support unlimited collaborators, which is unusual at the price point even though most micro-businesses will only need one user.

Cons

• Not MTD-compatible. The single biggest issue for UK users. Wave cannot file VAT to HMRC and is not on HMRC’s recognised software list for VAT or ITSA.
• No UK payroll. Wave Payroll exists only in the United States and Canada. UK employers cannot use Wave to run PAYE, file RTI submissions or manage pension auto-enrolment.
• No native UK payment processing. Wave Payments is unavailable in the UK, so collecting card payments requires a manual workaround through Stripe or PayPal.
• Patchy UK bank feeds. Bank import on Pro relies on a US-focused aggregator with inconsistent UK bank coverage; many users find feeds break or are unsupported.
• No UK tax automation. There is no built-in UK VAT scheme logic (standard rate, flat rate, cash accounting), no CIS handling, no IR35 awareness, and no Self Assessment output.
• US-centric support. Customer support hours and live chat are aligned with North American time zones, with no UK-based support team.
• No accountant portal in the UK. Most British accountants are unfamiliar with the product, and there is no advisor partner programme equivalent to Xero Partner or QuickBooks ProAdvisor for UK firms.
• Pricing presented in US dollars. UK customers are billed in USD on the Pro plan, which exposes them to exchange rate fluctuations and card fees.
• No Companies House filing or Corporation Tax computation. Limited companies cannot use Wave to produce statutory accounts or file at Companies House.

When to pick Wave

Wave is a sensible choice in a narrow set of UK scenarios:

• Sole trader trading below the £90,000 VAT registration threshold. If you are not VAT-registered and have no plans to register voluntarily, Wave’s free plan covers basic invoicing and expense tracking adequately.
• Freelancer or side-business owner whose income falls below MTD ITSA thresholds. With MTD ITSA arriving in April 2026 for income above £50,000, Wave can serve self-employed users below that level for now.
• Single-business or solo consultant who only needs invoicing. If your bookkeeping needs are simply “send invoices, log expenses, see what I earned,” Wave handles that competently at zero cost.
• Side hustle or hobby business not yet ready to invest in paid software. For a side project earning a few thousand pounds a year, Wave is a defensible starting point until the business grows enough to need a UK-focused tool.
• Cross-border freelancer with US or Canadian clients. If most of your clients are in North America and you accept payment in USD or CAD, Wave’s regional fit may actually be an advantage.

When NOT to pick Wave

Most UK businesses should look elsewhere. Specifically, do not pick Wave if any of the following apply:

• You are VAT-registered or expect to be soon. Use Pandle (free with MTD VAT submission), Bokio (free tier with MTD), or FreeAgent (free with NatWest, Mettle or Royal Bank of Scotland business accounts) instead.
• You will fall within MTD ITSA from April 2026. FreeAgent, Coconut or Xero are all HMRC-recognised and will handle quarterly submissions.
• You run a limited company. FreeAgent and Crunch include Corporation Tax and Companies House filing; Wave does neither.
• You employ staff or run payroll. Wave has no UK payroll. Use QuickBooks Online, Xero with Xero Payroll, or Sage Accounting with Sage Payroll.
• You are a contractor inside or outside IR35. FreeAgent has built-in IR35 reporting; Crunch offers a managed accountant service; Wave has neither.
• You are a landlord. Hammock is built specifically for UK landlords and handles Section 24 mortgage interest correctly; Wave does not.
• You need reliable UK bank feeds. Xero, QuickBooks Online, FreeAgent and Coconut all use Open Banking with broad UK bank coverage.
• You want a UK-based accountant to work in your file. Almost no UK accounting practice supports Wave; switch to Xero, QuickBooks Online or Sage for a far easier handover.

Comparable software

Wave sits in an unusual cluster: free or low-cost cloud bookkeeping for very small businesses. The most relevant alternatives for UK readers are products that combine a low entry price with proper HMRC integration. Pandle is the closest UK equivalent to Wave’s free positioning, and unlike Wave it is MTD-recognised. Bokio is another free-tier option built with UK and Swedish small businesses in mind. FreeAgent, while not free outright, comes free with several UK business bank accounts and is designed end-to-end for British sole traders, contractors and limited companies. Coconut is a strong choice for sole traders who want a mobile-first experience with HMRC integration baked in. The cards below show similar products you may want to compare.

FAQs

Is Wave really free in the UK?

The Starter plan is genuinely free with no time limit, no invoice cap and no feature throttling on its core invoicing and expense tracking. The Pro plan is paid, billed in US dollars, and adds bank import, receipt scanning and automated reminders.

Is Wave MTD-compatible for UK VAT?

No. Wave is not on HMRC’s recognised software list for Making Tax Digital. It cannot submit VAT returns to HMRC and is not registered as an MTD bridging tool. UK VAT-registered businesses should not use Wave as their primary record-keeping system.

Can I use Wave to file Self Assessment?

Wave does not produce SA100, SA103 or any HMRC-formatted self-employment pages. You can use the figures from Wave’s profit and loss report to fill in your Self Assessment manually through HMRC’s online portal, but there is no direct filing integration. From April 2026, sole traders with income above £50,000 must use MTD-recognised software, which Wave is not.

Does Wave do UK payroll?

No. Wave Payroll is available only in the United States and Canada. UK employers must use a separate payroll product such as Xero Payroll, BrightPay, Moneysoft, QuickBooks Payroll or Sage Payroll.

Can I accept card payments on Wave invoices in the UK?

Not natively. Wave Payments is not offered in the UK. You can include a manual link on your invoice to a Stripe Checkout, PayPal.me or other payment page, but there is no automatic reconciliation back into Wave.

Will Wave connect to my UK business bank account?

Sometimes. Pro tier bank feeds are powered by a US-focused aggregator, and UK bank coverage is inconsistent. Some major UK banks connect, others do not, and feeds can break without warning. Xero, QuickBooks Online, FreeAgent and Coconut have far more reliable UK Open Banking integration.

Is Wave secure?

Wave uses standard cloud security practices including TLS encryption, two-factor authentication and regular backups. As a North American product owned by H&R Block, it falls under US and Canadian data protection regimes. UK users should review the data residency implications under UK GDPR before storing customer data in the platform.

Can my UK accountant work in my Wave file?

In theory, yes; in practice, very few UK accountants are familiar with Wave. There is no UK accountant partner programme equivalent to Xero Partner or QuickBooks ProAdvisor. If you want your accountant to access your books, products like Xero, QuickBooks Online, Sage or FreeAgent will be far easier for them to work with.

What is the difference between Wave Starter and Wave Pro?

Starter is free and includes unlimited invoicing, estimates, customer and vendor records, manual expense entry and basic reports. Pro is paid (around £12 per month, billed in USD) and adds automatic bank import, receipt scanning, unlimited receipt uploads, automated late payment reminders and reduced payment processing fees in the US and Canada.

Should a UK limited company use Wave?

No. Wave does not produce UK statutory accounts, does not file at Companies House, does not compute Corporation Tax, does not handle UK payroll and is not MTD-recognised. Limited companies should use FreeAgent, Xero, QuickBooks Online, Sage Accounting or Crunch instead.

Final summary

Wave is a capable free invoicing and expense tracking tool with a clean interface and a strong reputation among North American micro-businesses. For a narrow band of UK users, specifically sole traders below the VAT threshold, outside MTD ITSA, with no employees and no need for advanced bank feeds, the Starter plan offers genuine value at no cost. The mobile invoicing apps and professional templates make it a credible option for freelancers who only need to bill clients and log expenses.

For everyone else in the UK, however, Wave is the wrong tool. The lack of MTD recognition is decisive: any VAT-registered business or any sole trader who will fall under MTD ITSA from April 2026 needs HMRC-recognised software, and Wave is not it. Add the absence of UK payroll, unreliable bank feeds, no native payment processing, no Companies House or Corporation Tax filing and almost no UK accountant familiarity, and the case for Wave evaporates quickly. UK alternatives such as Pandle (free with MTD VAT), Bokio (free tier), FreeAgent (free with several business bank accounts) and Coconut (sole trader focused) all offer a better fit at comparable cost. Use Wave only if its narrow sweet spot matches your situation exactly; otherwise pick a UK-built product that will still serve you when your business grows.
