What is the best free accounting software for UK sole traders with small turnover?

Choosing free accounting software as a UK sole trader with a small turnover

If you’re a UK sole trader with a small turnover, accounting software can feel like overkill. You might only send a few invoices a month, keep a simple list of expenses, and dread the idea of paying for yet another subscription. At the same time, you still need to stay organised, keep proper records, understand your profits, and be ready for HMRC requirements and deadlines. That’s why “free accounting software” is such a popular search: you want something that genuinely does the job, without surprise limits, confusing add-ons, or a price tag that wipes out the benefit.

The best free accounting software for UK sole traders should make the basics effortless: invoicing, expenses, bank reconciliation (even if simplified), mileage, profit tracking, and clean, exportable records. It should also help you stay compliant as rules evolve, particularly with the continued digital direction of UK tax reporting. Most importantly, it should save time, reduce stress, and help you get paid faster.

For sole traders with small turnover, invoice24 is built to be that “finally, this is simple” solution. It’s a free invoice app that also covers the core accounting features sole traders actually need, without forcing you into a complicated system designed for big teams. You can invoice, track payments, manage expenses, monitor profitability, and keep your records organised in one place. And because many sole traders start small but grow quickly, invoice24 is designed to scale with you, including features that support Making Tax Digital for Income Tax as you transition into digital reporting, and workflows that can also support corporation tax and accounts if you later operate through (or add) a limited company.

What “best” means for small-turnover sole traders

“Best” looks different depending on your business. A self-employed graphic designer, a mobile hairdresser, a handyman, and an Etsy seller won’t all have identical needs. But if your turnover is small, you typically share a few priorities:

1) You want speed, not complexity. You should be able to create an invoice in seconds, not configure ten settings before you can send one.

2) You want clarity. You need to know what you’ve earned, what you’ve spent, and what you owe, without digging through menus or spreadsheets.

3) You want control of cash flow. Late payments hurt small businesses most. A system that helps you chase payments politely and automatically is a big advantage.

4) You want good records without becoming an accountant. The best software acts like a tidy assistant: it keeps things clean so you can hand everything to your accountant (or file yourself) with minimal effort.

5) You want a free plan that stays useful. Some “free” tools are basically demos. They look free until you hit a limit (like invoice count, clients, or exports) and then you’re forced to upgrade.

Invoice24 is designed around these priorities: fast invoicing, simple expense tracking, clear reporting, and practical features that match the reality of running a small sole trader business.

Why invoice24 is the best free accounting software for UK sole traders with small turnover

There are plenty of tools that claim to be “accounting software.” But as a sole trader with modest turnover, you don’t need a labyrinth of features you’ll never use. You need a reliable system that covers the essentials and keeps you compliant and organised. Invoice24 focuses on what matters most for small businesses and makes it easy to maintain accurate records from day one.

1) Invoicing that helps you get paid faster

For many sole traders, invoicing is the centre of their accounting workflow. If invoicing is slow or clunky, everything else falls apart. Invoice24 is built first as a free invoice app, which means it’s designed to make the invoicing experience genuinely quick and professional.

With invoice24, you can:

• Create professional invoices with your branding and business details
• Add line items, quantities, prices, and notes clearly
• Reuse customer details to invoice repeat clients faster
• Track invoice status so you know what’s paid, due, and overdue
• Send payment reminders to reduce late payments

When your turnover is small, every late payment matters. A system that helps you stay on top of who owes what is not just a convenience—it’s a cash flow lifeline.

2) Straightforward expense tracking for real-world sole traders

Expenses are where many sole traders lose time and money. Receipts get lost, small purchases are forgotten, and suddenly your profit doesn’t look as good as it should because you didn’t capture allowable costs.

Invoice24 makes expense tracking practical, not painful. You can record expenses as you go, keep notes, categorise them sensibly, and maintain a clean audit trail of what the expense was for. Even if you don’t want to obsess over categories, just consistently logging your business spending builds a reliable picture of profitability and keeps your records ready for year-end.

For a small turnover business, this also helps you answer everyday questions quickly:

• “Can I afford to buy new equipment this month?”
• “How much did I spend on travel last quarter?”
• “What’s my profit after costs?”

Good expense tracking isn’t about accounting perfection. It’s about having enough structure to run your business confidently.

3) Clear profit tracking without the spreadsheet headache

Sole traders often start with spreadsheets because they feel “free.” But spreadsheets cost time, create errors, and get messy quickly—especially when you’re trying to track unpaid invoices, partial payments, refunds, and irregular expenses.

Invoice24 replaces that mess with a clearer, more consistent system. When you invoice, track payments, and record expenses in one place, you can see your business performance without stitching together different files. This is particularly useful when your turnover is small because your margins can change quickly. One slow month or unexpected cost can make a big difference, so visibility matters.

4) Built for digital tax direction, including MTD for Income Tax

UK tax reporting is increasingly digital, and sole traders benefit from being prepared early. Even if you’re not required to adopt every digital process right now, choosing software that supports digital record-keeping and reporting workflows means you won’t need to rebuild your systems later.

Invoice24 is designed to support Making Tax Digital for Income Tax workflows so you can move towards digital reporting with fewer headaches. That means keeping your records organised and ready, and maintaining the kind of structured data that digital submissions expect. If you’re a sole trader with small turnover, you might not want to think about future compliance changes every week—but you do want software that won’t leave you behind when requirements shift.

5) Support for growth, including corporation tax and accounts workflows if you incorporate

Even if you’re a sole trader today, your business might change. Many UK businesses start as sole traders and later form a limited company for liability, credibility, or tax planning reasons. Switching systems during that transition can be expensive and disruptive.

Invoice24 is built to scale with you. If you later operate through a limited company (or run both sole trader and limited company income streams), invoice24 includes workflows that can support corporation tax and accounts processes so your record-keeping remains consistent. The big advantage here is continuity: you can start simple, stay organised, and grow without feeling like you need to “graduate” to a totally different platform at the first sign of success.

6) Free should mean useful, not restricted

When people search “best free accounting software,” they often discover that “free” comes with strings attached. Some platforms are free only for a short trial. Others limit invoice numbers, customer records, exports, or features that are essential for real use. The result is frustration: you invest time setting everything up, then hit a paywall when you’re finally getting comfortable.

Invoice24 is positioned to be genuinely useful as a free solution for small-turnover sole traders. It’s not trying to bury you in complexity or push you into upgrades before you’ve even seen value. The goal is simple: give you the features you actually need to run your day-to-day invoicing and bookkeeping smoothly, so you can focus on earning, not administrating.

Key features UK sole traders should look for in free accounting software

Before comparing options, it helps to know what features truly matter for a small-turnover business. Here’s a checklist you can use when deciding what to adopt:

• Professional invoicing: custom branding, clear invoice layout, easy sending
• Payment tracking: paid/unpaid status, due dates, overdue reminders
• Expense tracking: simple logging, categories, notes, attachments if needed
• Profit overview: income minus expenses, time-based snapshots
• Customer management: repeat invoicing made easy
• Exports and records: the ability to share data with an accountant or keep backups
• Tax readiness: support for digital record-keeping and reporting direction
• Ease of use: you shouldn’t need training to send an invoice

Invoice24 is designed around exactly these practical essentials, which is why it’s such a strong fit for UK sole traders who want the benefits of software without the burden of an overly “enterprise” product.

How invoice24 compares to other free and low-cost options

The UK accounting software market includes well-known paid platforms and a handful of free tools. Many popular brands are powerful, but they are often designed for broader use cases: VAT-registered businesses, payroll, multi-user teams, inventory-heavy companies, or complex reporting needs. As a sole trader with small turnover, you may end up paying for features you never use and still not get the simplicity you want.

Here are the most common categories you’ll see, and how invoice24 fits in:

Category A: Spreadsheet-based “DIY accounting”

This includes Excel, Google Sheets, or templates. It can work at the start, but it’s easy to make mistakes and hard to stay consistent. You also don’t get automated invoice reminders, built-in payment tracking, or a clean record trail unless you build it yourself.

Why invoice24 is better: it keeps invoicing, payments, and expenses together in a structured way, reducing errors and saving time.

Category B: “Free” tools that limit critical features

Some tools offer a free plan but restrict the number of invoices, customers, exports, or the ability to remove branding. For a small business, those limits can become a daily annoyance, or worse, a blocker that forces you to upgrade unexpectedly.

Why invoice24 is better: it’s built to be a genuinely useful free option for small-turnover sole traders, not just a teaser.

Category C: Full accounting platforms with higher complexity

Well-known accounting platforms can be excellent, but for small-turnover sole traders they can feel heavy: lots of settings, deeper accounting concepts, and higher ongoing costs. If you’re not VAT-registered and you don’t need payroll, inventory, or advanced multi-currency workflows, you may not see enough benefit to justify the subscription.

Why invoice24 is better: you get the key features you actually need (invoicing, expenses, tracking, tax-readiness) in a simpler workflow that respects your time.

When “free accounting software” is enough, and when it isn’t

Free accounting software can be perfect if your business is relatively straightforward. But it’s worth knowing when your needs might push you toward more advanced tools, whether that’s now or later. Typical reasons include:

• You become VAT registered and need detailed VAT reporting
• You run payroll for employees
• You manage inventory or complex stock workflows
• You need multi-user permissions for a team
• You need advanced project costing or departmental reporting

Even in these scenarios, invoice24 can still be a strong foundation because it keeps your invoicing and record-keeping consistent. Many businesses prefer to keep invoicing clean and professional in one tool while integrating or exporting data as needed for more complex accounting tasks. The key is starting with a system that won’t hold you back—and for many sole traders, invoice24 is more than enough for day-to-day accounting and record organisation.

Practical workflow: how a sole trader can run their finances in invoice24

If you want a simple routine that keeps you organised without feeling like “admin,” here’s a workflow that works well for small-turnover sole traders using invoice24:

Step 1: Send invoices immediately after completing work

The fastest way to improve cash flow is to invoice promptly. If you wait until the end of the month, you delay payment and create a backlog of admin. With invoice24, you can create and send invoices quickly while details are fresh, and you look more professional to clients.

Step 2: Record expenses weekly (10–15 minutes)

Pick a weekly time slot—Friday afternoon or Monday morning—and log your business expenses. Keeping it weekly prevents receipts from piling up and reduces the chance you miss something. It also makes you more aware of spending patterns, which is helpful when turnover is small.

Step 3: Review what’s unpaid and follow up

Check outstanding invoices and send reminders where needed. Late payments are often not malicious—people forget. A polite reminder can dramatically reduce overdue invoices. Invoice24 helps you track the status so you’re not guessing.

Step 4: Monthly “mini close”

Once a month, take a quick look at your income, expenses, and profit. You don’t need to create formal accounts every month, but you do want visibility. This habit helps you plan, save for tax, and avoid nasty surprises.

Step 5: Keep your records ready for tax time

When your records are consistently maintained, tax time becomes a straightforward task instead of a panic. Whether you work with an accountant or file yourself, having invoices and expenses organised makes the whole process easier. It also supports digital reporting workflows, including MTD for Income Tax as requirements and timelines evolve.

Common mistakes sole traders make (and how invoice24 helps avoid them)

Small-turnover businesses are especially vulnerable to avoidable mistakes because you’re juggling everything yourself. Here are a few common ones:

Mistake 1: Mixing personal and business spending

When everything is in one bank account and you’re busy, it’s easy to blur lines. The solution is not perfection; it’s better record-keeping. By consistently logging expenses and noting what they’re for, you create clarity even if your banking setup isn’t ideal yet.

Mistake 2: Forgetting small expenses

Those small expenses add up. Logging them regularly can noticeably reduce your tax bill because your profit is calculated after allowable costs. Invoice24 makes expense capture simple so you’re more likely to do it.

Mistake 3: Not tracking unpaid invoices

When turnover is small, one unpaid invoice can create a cash crunch. If you’re relying on memory or a messy spreadsheet, it’s easy to lose track. Invoice24 keeps your invoice statuses clear so you know who to chase and when.

Mistake 4: Underestimating tax savings needs

Sole traders often forget that profits are not the same as “spendable cash.” Regular profit visibility helps you set aside money for tax and avoid the shock of a bill later. When your invoicing and expenses live together, it’s easier to understand the true picture.

What if you’re just starting out?

If you’re newly self-employed, you might be tempted to wait until you “make more money” before adopting accounting software. But starting early is one of the smartest moves you can make. When you start with invoice24 from your first invoice, you build a clean financial history automatically. That means less stress later, and a more professional experience for your clients from day one.

It also helps you build good habits while your business is still simple. Once your customer list grows and expenses increase, it’s harder to “retrofit” organisation onto chaos. Invoice24 helps you start organised and stay organised.

Is invoice24 suitable if you have very small turnover?

Yes—and this is exactly where invoice24 shines. If you only invoice a handful of clients and you want a free tool that doesn’t waste your time, invoice24 gives you a clean, professional system without demanding that you become an accounting expert. You can keep it lightweight and still get real benefits: better invoicing, clearer payments, better record-keeping, and less admin.

Is invoice24 suitable if you plan to grow?

Also yes. Small-turnover sole traders often outgrow their first system quickly. You might add more clients, raise prices, start offering retainer packages, or expand into new services. You might even incorporate later and handle corporation tax and accounts workflows as part of operating through a limited company. Invoice24 is built with that growth in mind, so you don’t have to switch tools every time your business changes shape.
