Best accounting software for small businesses

The right accounting software depends entirely on your size and type of business, which is why a single ranked list is close to useless. This is the segmented, honest version: a genuinely free option, the best pick for freelancers, for limited companies, and for ecommerce, and clear guidance on what actually matters when you choose.

The quick answer: on a tight budget, Wave is genuinely free (and we earn nothing from it). Freelancers and small limited companies often land on FreeAgent, which is free through some bank accounts. Growing businesses tend toward Xero or QuickBooks for the extra depth. Match the tool to your size, not to whichever markets hardest.

What actually matters when choosing

Making Tax Digital compatibility. As HMRC's Making Tax Digital rules widen, your software increasingly needs to file directly rather than just record. This is now close to a baseline requirement rather than a nice-to-have, so confirm any option you're considering is compatible.

Bank feeds. Automatic bank feeds pull your transactions in so you reconcile rather than type. This is the single biggest time-saver in any accounting tool, and the difference between books that stay current and books you dread.

The right size for you. A sole trader doesn't need enterprise inventory features, and paying for depth you'll never touch is a common, avoidable waste. Match the tool to your actual needs today, not to what you imagine you might need in three years.

What your accountant uses. If you have (or will have) an accountant, the platform they're comfortable working in matters, they'll spot issues faster and you'll get more from their input. It's worth asking before you commit.

The options compared

| Software | Cost | Best for | |---|---|---| | Wave | Free | Sole traders and freelancers on a tight budget | | FreeAgent | Paid (often free with certain business bank accounts) | Freelancers, contractors and small limited companies | | Xero | Paid subscription | Growing businesses wanting depth and a large add-on ecosystem | | QuickBooks | Paid subscription | All-round small business use, strong reporting and inventory |

We earn nothing from Wave, and we're listing it first on purpose, if budget is your main constraint and your needs are simple, it's a genuinely fair place to start.

Best for freelancers and sole traders

If budget matters most, Wave covers invoicing and basic bookkeeping for free. If you want something built more specifically around self-employment and Self Assessment, FreeAgent is popular, and it's often included free if you bank with certain providers, which makes it effectively free for a lot of freelancers. Check whether your business bank account bundles it before paying separately, our answer on is FreeAgent really free? explains how that works.

Best for limited companies

Small limited companies often find FreeAgent fits well, particularly for its handling of the salary and dividend split, Corporation Tax estimates and director-specific features. As the company grows, more moving parts, staff, inventory, multiple people needing access, Xero or QuickBooks offer more depth and a broader ecosystem of integrations. All of these handle Making Tax Digital, so compliance isn't the deciding factor, capability and cost are.

Best for ecommerce

Ecommerce brings complications a service business never sees: inventory valuation, marketplace fees, multi-channel sales, and VAT that arrives sooner than expected because it's turnover-based. Xero and QuickBooks tend to lead here specifically because of stronger inventory and multi-channel integration options than the more freelancer-focused tools. Our ecommerce detail covers the related banking side.

Is FreeAgent really free?

This causes genuine confusion, so it's worth being clear. FreeAgent isn't a free product in its own right, it's a paid subscription that becomes free to you if you bank with certain providers who include it as a perk. If you don't bank with one of those, it's a normal paid subscription to weigh against Xero and QuickBooks. It's rarely worth switching banks purely to get it free, but if a bank that includes it also suits you on its own merits, it's a genuine bonus.

Do you even need software, or will a spreadsheet do?

For a very small, low-volume sole trader with no VAT registration and no staff, a well-organised spreadsheet can genuinely be enough. The point where that stops being true is when Making Tax Digital rules apply to you (a spreadsheet alone won't file), when transaction volume makes manual entry error-prone and time-consuming, or when you register for VAT. Because a free option like Wave exists, budget is rarely a good reason to stay on spreadsheets once you've outgrown them, our do I need accounting software? answer goes deeper.

How much does accounting software cost?

Pricing spans from free to a meaningful monthly subscription, and the honest answer is that the cheapest option isn't automatically the best value. Wave is free for the essentials. FreeAgent is a paid subscription, but effectively free if it's bundled with your business bank account. Xero and QuickBooks are paid subscriptions, usually tiered so you pay more as you need more features (payroll, multi-currency, higher transaction volumes, more users).

The trap to avoid is paying for a higher tier "to be safe" before you actually need its features. Most small businesses are better served starting on a low or free tier and upgrading only when a specific need appears, an extra user, payroll, inventory, rather than paying for capability that sits unused. Weigh the subscription against the time it genuinely saves you and, where relevant, whether your accountant works in it.

How to switch accounting software later

Switching is more common than people expect, and less painful than they fear. Businesses commonly move as they grow, from a free tool to a paid one, or from one paid platform to another their accountant prefers. The main things to get right are timing the switch around a clean point (often a financial year end), bringing your opening balances across accurately, and making sure historical records remain accessible. An accountant will usually manage a migration for you if the switch is tied to taking them on. The lesson isn't to agonise over the "forever" choice up front, it's to pick something sensible now and know that moving later is a manageable task, not a trap.

Software doesn't replace an accountant

Good software makes bookkeeping far easier and handles a lot of the day-to-day recording, but it doesn't make the judgement calls an accountant makes on tax efficiency, or carry the accountability of someone signing off your figures. Most people use both together: software for the mechanics, an accountant for the decisions and the sign-off. Our can I start a business without an accountant? answer covers when you genuinely need one.

FAQs

Which accounting software is genuinely free? Wave is genuinely free for invoicing and basic bookkeeping, with no forced upgrade for the essentials, and we earn nothing from recommending it.

Do I need Making Tax Digital-compatible software? Increasingly yes, as the rules widen. VAT-registered businesses already need it, and requirements are extending to more taxpayers over time. Confirm compatibility before committing to any tool.

Can my accountant use a different platform than me? They can, but it's smoother if you use one they're comfortable with, they'll work faster and add more value. Worth asking before you choose.

Is FreeAgent free through my bank? It's included free with certain business bank accounts. Check whether yours does before subscribing separately.

Should I use a spreadsheet or software? A spreadsheet can work for a very simple, low-volume sole trader, but once Making Tax Digital applies, you're VAT registered, or volume grows, software (a free one like Wave included) becomes the practical choice.
