Best Free Tools for UK Sole Traders 2026

Starting a business on a tight budget means scrutinising every expense, and software is no exception. The good news for UK sole traders in 2026 is that there are more free and freemium tools available than ever before. The bad news is that free tools come with limitations, and cobbling together five or six different apps creates its own headaches.

In this guide we will walk through the best free tools available in each category, rate their usability honestly, explain where they fall short, and show how Accounted's 30-day free trial offers a comprehensive alternative. We are not pretending to be unbiased, but we will be fair. Some free tools are genuinely excellent, and we will say so.

HMRC's Own Free Tools

Before looking at third-party software, it is worth knowing what HMRC provides directly, at no cost.

Basic PAYE Tools

If you employ staff, HMRC's Basic PAYE Tools is a free desktop application that handles payroll for up to nine employees. It calculates tax and National Insurance, produces payslips, and submits Real Time Information (RTI) reports to HMRC. For micro-employers, it does the job adequately.

Usability: 5/10. The interface is dated and unintuitive. Installation can be fiddly, especially on newer operating systems. It works, but it feels like software designed by a government department, because it was.

Limitations: Only supports up to nine employees. No cloud access, so you are tied to one computer. No integration with bank accounts or other software. If you need to run payroll from your phone or while travelling, this is not the tool for you.

MTD-Compatible Spreadsheet Bridges

For sole traders who prefer to keep their books in a spreadsheet, HMRC permits the use of bridging software that takes data from your spreadsheet and submits it in the required digital format. Several free spreadsheet bridges exist, and HMRC maintains a list of MTD-compatible software that includes both free and paid options.

Usability: 4/10. The bridge itself is usually simple enough, but the underlying requirement is that you maintain your spreadsheet correctly. If your spreadsheet has errors, the bridge will faithfully submit those errors to HMRC. There is no validation, no categorisation help, and no error checking.

Limitations: You are still doing all the bookkeeping manually. The bridge is just a submission mechanism, not a bookkeeping tool. For anyone processing more than a handful of transactions per month, this approach is fragile and time-consuming.

HMRC App and Online Services

The HMRC app lets you check your tax position, view your National Insurance record, claim a refund, and manage some aspects of your Self Assessment. It is free and reasonably well designed.

Usability: 7/10. For what it does, it works well. The app is clean, responsive, and improving with every update.

Limitations: It is not a bookkeeping tool. You cannot categorise transactions, track expenses, or prepare a tax return through the app. It is useful for checking your tax code and viewing your statement, but it will not help you run your business finances.

Free Accounting Software

Several providers offer free tiers of their accounting software, and these are worth considering if your needs are simple.

Wave

Wave is a Canadian-owned platform that offers genuinely free accounting and invoicing with no transaction limits. It makes money through payment processing and payroll services rather than subscription fees.

Usability: 7/10. The interface is clean and modern. Bank connections work reasonably well, and the invoicing module is solid. For a free tool, it is impressive.

Limitations: Wave's UK support is limited. Bank feeds can be unreliable with some UK banks, and the platform does not natively support Making Tax Digital submissions. You would need a separate MTD bridge, which adds complexity. Customer support is minimal on the free tier, and there is no AI-powered categorisation, so you are sorting every transaction manually.

Pandle

Pandle offers a free tier that includes basic bookkeeping, invoicing, and bank feeds for a single bank account. It is UK-based and designed specifically for the UK market.

Usability: 6/10. Functional but basic. The free tier does the essentials, and the UK focus means VAT and Self Assessment features are baked in. The interface is not the most polished, but it gets the job done.

Limitations: The free tier restricts you to one bank account and does not include receipt scanning, multi-currency support, or advanced reporting. MTD submissions require the paid tier. If your business grows beyond the most basic level, you will hit the limitations quickly.

Zoho Books (Free Tier)

Zoho Books offers a free plan for businesses with annual revenue under £35,000 (approximately, as the threshold is set in dollars). It includes invoicing, expense tracking, and bank feeds.

Usability: 7/10. Zoho's interface is well-designed and the feature set on the free tier is generous. Bank reconciliation works smoothly, and the mobile app is capable.

Limitations: The revenue threshold means you will outgrow the free tier as your business succeeds, which is somewhat ironic. UK-specific features like MTD submission are available but not as deeply integrated as UK-native platforms. Zoho's ecosystem is vast, which can be overwhelming if all you need is simple bookkeeping.

Receipt Scanning Apps

Keeping receipts is a legal requirement, and scanning apps make it manageable.

Dext (Formerly Receipt Bank) — Limited Free Option

Dext offers a limited number of free scans per month on some plans. It is the market leader in receipt capture for a reason: the OCR (optical character recognition) is excellent, and it integrates with most major accounting platforms.

Usability: 8/10. Snap a photo, and Dext extracts the date, amount, supplier, and VAT automatically. It is fast and accurate.

Limitations: The truly free allowance is very limited. To use it seriously, you need a paid subscription, and Dext is not cheap. It also does not do your bookkeeping; it captures receipts that then need to be processed in your accounting software.

Smart Receipts (Free, Open Source)

Smart Receipts is a free, open-source app that lets you photograph receipts and organise them into trips or categories. It exports to PDF or CSV.

Usability: 5/10. It works, but the interface is utilitarian. OCR accuracy is lower than Dext, and there is no automatic integration with accounting software. You are essentially creating a digital filing cabinet, which is better than a shoebox but not by as much as you might hope.

Penny's Built-In Receipt Scanning

For completeness, Penny (Accounted's AI bookkeeper) includes receipt scanning as part of the core product. You forward a receipt by email or snap a photo through WhatsApp, and Penny not only extracts the details but matches the receipt to the corresponding bank transaction automatically. There is no separate app to manage, no export/import step, and no limit on the number of receipts. This is included in all Accounted plans and during the free trial. You can see how this compares to standalone tools on our Accounted vs Xero comparison.

Invoicing Tools

Getting paid starts with sending a professional invoice.

Invoice Ninja (Free Tier)

Invoice Ninja offers a generous free tier with unlimited invoicing, expense tracking, and time tracking. It is open source and well-maintained.

Usability: 7/10. The invoicing features are excellent. Templates look professional, recurring invoices work well, and the client portal is a nice touch.

Limitations: It is primarily an invoicing tool, not a bookkeeping solution. You will still need separate software for bank reconciliation, categorisation, and tax returns. The free tier supports up to 100 clients, which is ample for most sole traders.

PayPal Invoicing

If you already use PayPal, their invoicing feature is free and surprisingly capable. You can create and send invoices, track payment status, and send reminders.

Usability: 6/10. Simple and effective for basic invoicing. The integration with PayPal payments is seamless.

Limitations: You are locked into PayPal's payment ecosystem, which charges processing fees. The invoicing features are basic compared to dedicated tools, and there is no connection to your bookkeeping.

Mileage Trackers

If you drive for business, tracking mileage is essential for claiming the approved mileage rates (currently 45p per mile for the first 10,000 miles, then 25p per mile).

MileIQ (Free Tier)

MileIQ automatically detects when you are driving and logs the trip. You swipe to classify each trip as business or personal.

Usability: 8/10. The automatic detection is genuinely clever. The swipe interface is quick and satisfying. It is the best-designed mileage tracker available.

Limitations: The free tier limits you to 40 trips per month. For many sole traders, especially those in trades or delivery, that is not enough. The paid version is reasonably priced but adds yet another subscription to manage.

Stride (Free)

Stride is completely free and offers mileage tracking alongside basic expense and income logging. It is aimed at self-employed workers.

Usability: 6/10. Functional but less polished than MileIQ. The automatic trip detection is less reliable, and you may need to start and stop tracking manually.

Limitations: The expense and income tracking features are too basic to replace proper bookkeeping software. It is best used purely for mileage.

Time Tracking and Project Management

Toggl Track is the gold standard for time tracking. The free tier supports up to five users with a beautifully designed interface that works across all devices (Usability: 9/10). The free tier lacks billable rates and advanced reporting, but for pure time tracking it is excellent. Trello's free kanban boards are similarly strong for project management (Usability: 8/10), though neither tool handles any financial functions.

The Problem with Stitching Free Tools Together

By now, a pattern has emerged. Each free tool does one thing reasonably well but nothing comprehensively. To cover your bases, you might end up using Wave for accounting, Dext for receipts, Invoice Ninja for invoicing, MileIQ for mileage, Toggl for time tracking, and the HMRC app for checking your tax position. That is six different apps, six different logins, six different data silos, and no integration between them.

The result is fragmented data, duplicated effort, and gaps where information falls through the cracks. This is where Accounted takes a fundamentally different approach. Penny handles bookkeeping, receipt scanning, transaction categorisation, invoicing, mileage tracking, and MTD compliance in a single, integrated platform. Everything is connected because everything lives in one place.

Why Accounted's Free Trial Is Worth Trying

We offer a 30-day free trial with full access to every feature. No credit card required, no feature restrictions, and no limits on the number of transactions or receipts. During those 30 days, Penny will categorise your transactions, match your receipts, flag anomalies, track your deadlines, and deliver weekly summaries of your financial position.

You can see our full pricing structure on our pricing page. For sole traders, the cost of Accounted is itself an allowable business expense, reducing your taxable profit.

Our Honest Assessment

Free tools have a genuine place in the sole trader's toolkit. HMRC's own services handle specific compliance tasks adequately. Toggl is a superb time tracker. For sole traders in the earliest stages of business, surviving on the absolute minimum, these tools can bridge the gap.

But as your business matures, the limitations compound. Manual data entry takes time. Disconnected systems create errors. Missing receipts lead to missed deductions. And the cognitive load of managing multiple platforms is a hidden cost that absolutely affects your productivity.
