The Best Free Tools for Small Businesses in 2026

The Accounted Editorial Team·1 March 2026·9 min read

Running a small business in the UK doesn't have to mean spending a fortune on software. Whether you're a newly registered sole trader watching every penny or an established freelancer looking to streamline your operations, there's an impressive range of free tools available in 2026 that can handle everything from bookkeeping to project management to marketing.

The key word here is "free" — and we mean genuinely free, not "free for 14 days then we'll charge you." While some of the tools on this list have paid tiers with additional features, every one of them offers a meaningfully useful free plan that you can use indefinitely.

We've organised this guide by business function so you can jump straight to what you need. Let's get into it.

Accounting and Bookkeeping

Getting your finances right is non-negotiable. With the personal allowance at £12,570, income tax at 20% on earnings between £12,571 and £50,270, and Making Tax Digital requirements expanding, you need reliable financial tools.

Wave

Wave has been a stalwart of free accounting software for years, and it remains a strong option in 2026. It offers unlimited invoicing, expense tracking, and financial reporting — all completely free. The revenue model is based on payment processing fees, so the core accounting features are genuinely no-cost.

It's particularly good for sole traders who need straightforward bookkeeping without the complexity of enterprise-level software. The main limitation is that it's designed for the North American market, so some UK-specific features (like MTD compatibility) require workarounds.

HMRC's Own Tools

Often overlooked, HMRC provides free tools for various tax obligations. The HMRC app lets you check your tax position, make payments, and manage your tax affairs. For VAT-registered businesses (those above the £90,000 threshold), HMRC-compatible software is available from several providers on free or low-cost plans.

Spreadsheets

Sometimes the simplest tools are the most effective. Google Sheets (free) or LibreOffice Calc (free, open-source) can handle basic bookkeeping perfectly well if you're disciplined about keeping them updated. HMRC accepts spreadsheet-based records provided they meet digital record-keeping requirements. That said, dedicated tools like Accounted save enormous amounts of time by automating what spreadsheets require you to do manually — Penny can categorise transactions automatically, which is something no spreadsheet can do.

Invoicing

Invoice Ninja

Invoice Ninja offers a generous free plan with unlimited invoicing, expense tracking, and basic time tracking. It's open-source, which means it's transparent about how it works and has an active community of developers improving it. You can customise invoice templates, set up recurring invoices, and accept online payments.

PayPal Business

If you already have a PayPal account, you can create and send professional invoices for free through PayPal Business. Clients can pay directly through the invoice, which speeds up payment. The obvious downside is PayPal's transaction fees, but for the invoicing functionality itself, there's no charge. Our guide on getting paid faster covers more strategies for reducing payment delays.

Zoho Invoice

Zoho offers a free invoicing plan for businesses sending fewer than 1,000 invoices per year (which covers most sole traders comfortably). It includes automated payment reminders, expense tracking, and multi-currency support.

Project Management

Trello

Trello's visual, card-based project management system is intuitive and surprisingly powerful. The free plan allows unlimited cards and up to 10 boards, which is more than enough for most sole traders. Use it to track projects, manage to-do lists, or organise your content calendar.

Notion

Notion has evolved into a remarkably versatile tool that can serve as a project manager, note-taking app, database, wiki, and more — all in one place. The free plan is generous for individual use, and the flexibility means you can mould it to fit almost any workflow. The learning curve is steeper than Trello, but the payoff is a single tool that replaces several.

Asana

Asana's free plan supports up to 10 users (more than enough for a sole trader and any collaborators), with unlimited tasks, projects, and basic reporting. It's more structured than Trello, with list views, board views, and timeline views. If you manage complex projects with multiple phases and dependencies, Asana's free tier is hard to beat.

Communication

Google Workspace (Personal)

Gmail, Google Calendar, Google Meet, Google Drive — Google's suite of productivity tools is free for personal use and more than adequate for most sole traders. You get 15GB of cloud storage, video conferencing for up to 100 participants, and seamless integration between apps.

For a more professional appearance, you might eventually want a custom email domain (you@yourbusiness.co.uk), which requires the paid Google Workspace plan. But for getting started, a Gmail address works fine.

Slack

Slack's free plan lets you search your most recent 90 days of messages and includes one-to-one video calls. If you work with clients or collaborators who use Slack, the free tier is perfectly adequate. The main limitation is the message history cap, which may matter if you need to reference old conversations.

Zoom

Zoom's free plan allows unlimited one-to-one meetings and group meetings of up to 40 minutes with up to 100 participants. For most client calls and virtual meetings, this is more than sufficient. If you regularly need longer group sessions, the paid plan is relatively affordable.

Marketing and Social Media

Canva

Canva has democratised graphic design. The free plan gives you access to thousands of templates, stock photos, and design elements. You can create social media graphics, presentations, business cards, flyers, and more — all without any design skills. It's genuinely one of the most useful free tools available for small businesses.

Buffer

Buffer's free plan lets you manage up to three social media channels and schedule up to 10 posts per channel at a time. For sole traders who want to maintain a consistent social media presence without spending hours on it, Buffer is excellent. Create a batch of content, schedule it, and get on with your actual work. We discuss this approach in more detail in our guide on automating your admin.

Mailchimp

Mailchimp's free plan supports up to 500 contacts and 1,000 email sends per month. For sole traders building an email list, this is a solid starting point. You get email templates, basic automation, and analytics — enough to run professional email marketing campaigns without spending a penny.

Google Business Profile

If you serve local customers, a Google Business Profile is essential — and it's completely free. It puts your business on Google Maps, lets customers leave reviews, and gives you a presence in local search results. For trades, hospitality, retail, and other location-based businesses, this is arguably the single most valuable free marketing tool available.

File Storage and Collaboration

Google Drive

15GB of free cloud storage, with full office suite (Docs, Sheets, Slides) built in. You can share files and folders with clients, collaborate in real time, and access everything from any device. For most sole traders, 15GB is more than enough for documents — though it fills up faster if you're storing photos or videos.

Dropbox

Dropbox's free plan offers 2GB of storage, which is modest but useful for sharing files with clients. The real strength of Dropbox is its reliability and ubiquity — almost everyone has used it, which makes collaboration straightforward.

WeTransfer

Need to send large files to a client? WeTransfer's free plan lets you send files up to 2GB at a time, with no account required. The files are available for seven days. It's not a storage solution, but for one-off file transfers, it's unbeatable in its simplicity.

Website and Online Presence

WordPress.com

WordPress powers over 40% of all websites on the internet, and the basic plan is free. You get a subdomain (yourbusiness.wordpress.com), basic templates, and enough functionality to create a simple business website. For a custom domain and more features, you'll need to upgrade, but the free plan is a legitimate starting point.

Carrd

If you just need a simple one-page website — an online business card, essentially — Carrd is hard to beat. The free plan allows up to three sites with basic functionality. It's incredibly easy to use and produces clean, professional-looking pages.

Google Analytics

Understanding who visits your website and what they do there is crucial for any online presence. Google Analytics is free, powerful, and integrates with virtually every website platform. It has a learning curve, but even basic use gives you valuable insights into your audience.

Time Tracking

Toggl Track

Toggl's free plan offers unlimited time tracking for up to five users. It's clean, simple, and available on every platform (web, desktop, mobile). For freelancers who bill by the hour, Toggl is particularly valuable — you can generate detailed reports showing exactly how you've spent your time, which makes invoicing straightforward and helps you identify where your hours actually go. Our guide on time tracking for freelancers explores why this matters.

Clockify

Clockify is completely free for unlimited users and unlimited tracking — no paid tier required for the core functionality. It offers timesheets, calendar views, and detailed reporting. If you need robust time tracking without any cost, Clockify is the go-to option.

Legal and Contracts

Shake

Shake offers free, legally sound contract templates that you can customise and send for e-signature. For sole traders who need basic service agreements, NDAs, or freelance contracts, it's a useful resource.

GOV.UK

The UK government's website is a goldmine of free resources for small businesses. From business registration to tax guidance to employment law, GOV.UK provides authoritative information at no cost. It's not the most exciting reading, but it's accurate and comprehensive.

Choosing the Right Tools

With so many free options available, the temptation is to sign up for everything. Resist this urge. Every tool you add to your workflow is another login to remember, another interface to learn, and another potential distraction. The most productive approach is to choose a small number of tools that work well together and commit to using them consistently.

Start with the essentials: bookkeeping, invoicing, and whatever project management system suits your workflow. Add other tools as specific needs arise, rather than accumulating software you never use.

And remember — "free" doesn't always mean "best." Sometimes a paid tool that saves you significant time is a better investment than a free tool that almost does what you need. The question to ask is: "Does this tool save me more time (and therefore money) than it costs?" If the answer is yes, it's worth paying for.

The Best Investment Is Your Time

Free tools are wonderful, but they're only valuable if they actually save you time and reduce friction in your business. The best free tool in the world is useless if it sits unused because it's too complicated, doesn't integrate with your workflow, or solves a problem you don't actually have.

Focus on the tools that address your biggest pain points, set them up properly, and give them a genuine trial. Your future self — the one with more time, less admin, and a clearer head — will be grateful.
