1. 🥇 Zoho Books: best for scaling businesses or those with unique accounting needs

Zoho Books’ cash flow dashboard

What is Zoho Books?

Zoho initially made its name with its CRM systems (check out our Zoho CRM review to learn more) but it has offered accounting software since 2011. From our research and user testing, Zoho Books’ free plan is the top free system overall.

Even on the free plan, users can design invoices and create custom ‘views’ to analyse transactions based on specific criteria. For example, if you’re a craft brewery that needs to track specific ingredients and production costs.

What do I get on the Zoho Books free plan?

As well as being an excellent customisation tool, Zoho Books is also fully Make Tax Digital compliant, which means it can be used to submit a VAT return to HMRC. These need to be sent every three months and they can be a pain to build, so it’s incredibly handy that Zoho Books permits this as part of its platform. You can also:

• Automate payment reminders
• Set up a customer portal for clients to view invoices
• Create business reports
• Produce (and schedule) recurring invoices

Zoho Books’ free plan is ideal for firms just starting out, but there are some convincing reasons to sign up for Zoho Standard (£10 per user, per month). Standard lets you create up to 5,000 invoices per year, while you’re limited to 1,000 on the free plan. This makes it more suitable for businesses with high transaction volumes, and SMEs with serious growth plans.

Another point is that Zoho Standard comes with bank feed integration. Once you’ve linked your business bank account, all transactions will automatically appear in Zoho Books. This is opposed to Zoho Free, where you have to download and import bank transactions manually: a time-consuming task that’s better avoided.

2. QuickFile: best for freelancers sending many invoices

Quickfile’s dashboard for invoicing, banking and important notes

What is QuickFile?

Founded in 2010, QuickFile is accounting software that’s specifically aimed at freelancers and self-employed workers. It’s a simple and intuitive cloud-based solution that helps entrepreneurs who are short on time to automatically chase and secure payments from slow clients.

What do I get with QuickFile?

QuickFile offers a good range of advanced accounting functions, on top of its USP of payment features. I particularly like that it can be used to create estimates, purchase orders, and delivery notes, making it a great option for dropshipping firms.

QuickFile also has a mobile app, which allows multi-tasking side hustlers to create invoices and snap expenses receipts on the go. It also automates with your bank feed (Zoho, in comparison, charges for this feature) so you can easily separate personal finances from revenues if you’re operating without a business bank account.

However, it is lacking some key capabilities. FreeAgent, for example, includes features that are designed to help freelancers manage their workload, such as time tracking and project management. It also offers self-assessment tax return filing, which QuickFile does not.

Though be aware QuickFile is also only free for accounts of a certain size. You’re limited to 1,000 ledger entries (encompassing invoices, purchases and bank transactions). Once you go over this limit, you pay a set fee of £60+VAT per year.  Its free platform is also full of annoying adverts that can clutter up your desktop.

3. FreeAgent: best for consultants or agencies working to short-term contracts

FreeAgent’s cash flow dashboard

What is FreeAgent?

Set up in 2007, FreeAgent is now used by over 90,000 small businesses across the UK. FreeAgent’s biggest benefit is its self-assessment tools that automatically fill in up to 90% of the self employment tax return form. Plus, unlike any other provider on this list, you can also use FreeAgent to pay employees, as the platform allows users to file auto-calculated PAYE and National Insurance directly to HMRC.

🚩 Despite the name, FreeAgent is not free for everyone. Only those who have a business current account with NatWest, Royal Bank of Scotland, Ulster Bank, or Mettle will qualify. If not, FreeAgent costs £19 per month for sole traders (or £9.50 for the first six months).

What can FreeAgent do?

FreeAgent has all of the core accounting features that Zoho Books and QuickFile offer. Interestingly, it also boasts time tracking tools, so you can easily view timesheets, which makes billing clients much simpler as you’ll know exactly how many hours you’ve completed on an account each month.

On top of this, FreeAgent has a projects view that clearly shows the income, time, and expenses associated with each project, and whether it’s making a profit or loss. Plus, a mobile app lets you view all of this data from your pocket.

Combined with its payroll and self-assessment features, all this makes FreeAgent a good option for small business agencies working on short-term contracts. You’ll be able to pay any freelancers you work with and see where all your hours were spent within a set time period.

As flagged above, FreeAgent is only free for certain business banking customers. Paid plans start a £19+VAT per month. All tiers have a 30-day free trial. This is one big prerequisite that the other software such as Zoho Books, and GnuCash don’t have.

What support does FreeAgent offer?

FreeAgent offers excellent customer service. It is the only brand on this list to offer both phone and email support channels during business hours (9am-5pm Monday to Thursday, and 9am-4pm on Friday). It also offers “Ruby the Robot”, a chat support function.

4. GnuCash: best for micro-businesses with low transaction volumes

GnuCash is a strong, completely free option for basic data entry and tracking your income and expenses.

What is GnuCash?

We’ll tell you upfront, unless you’re a software whizz with a coding background, you won’t get much out of GnuCash. This is because GnuCash is an open-source accounting software. That means anyone can download and edit the actual code that makes up the program in order to add extra functionality and fix errors.

Unlike VT Cashbook, it’s not particularly tailored to the needs of SMEs (there’s no open banking integration or mobile app, for example). It also does not support payroll, so you won’t be able to pay employees through the software.

What do I get with GnuCash?

GnuCash works in accrual-mode. That means it records expenses and sales when they take place, instead of when an invoice is actually settled. This is a smarter way of tracking transactions for businesses, but potentially a drawback for freelancers and gig workers, who will need to make fiddly manual edits if a payment is late.

GnuCash is best used for basic data entry. If you’re a micro-business with a limited number of transactions each month then you can use GnuCash to manage your finances while avoiding the complexity of feature-rich software.

GnuCash features a checkbook-style interface that allows you to record transactions via double entry accounting (where every transaction is recorded as a debit to one account and a credit to another). You’ll be able to register incoming bills or import your downloaded bank statements, and GnuCash can then:

• Automatically add VAT to sales invoices
• Add tax information to sales invoices (including for abroad clients)
• Generate a PDF invoice to send to clients
• Build reports to track profits and losses, or business overheads

What is VT Cash Book?

VT Software was founded in 1997, and its professional products (VT Accounts and VT Transaction+) are popular with small firms. VT Cash Book is its free starter product.

Cash Book is a straightforward, easy-to-use desktop accounting software that is most suitable for firms that want to manage their firms on a cash basis, rather than invoices (also known as accrual).

Because of this cash basis, the software only tracks income that’s been received and expenses that have been paid. This eliminates the need to chase outstanding invoices or account for pre-paid expenses, making bookkeeping more manageable. It’s also a more accurate reflection of your current cash situation.

However, this method can make it trickier to forecast future income, so it’s not ideal for firms with big sales volumes, as it can lead to mismatched revenue and expense recognition.

What do I get with VT Cash Book?

VT Cash Book is best thought of as a solid way to record your payments and receipts. It is short on advanced features, but you’ll be able to run limited reports on profit and loss, balance sheets, ledger activity, and transaction lists.

It’s designed to take manually inputted data from your bank and reconcile these statements with your accounts so you can correct simple mistakes. Once you have your final profits, however, you won’t be able to submit a VAT return; you’ll have to register with HMRC to do this separately yourself.

Crucially, VT Cash Book is unsuitable for professional services or B2B firms. Because it is entirely focused on managing businesses on a cash basis, VT Cash Book’s free plan has no invoicing features for overseeing payments from or to customers and suppliers.

This is a big limitation. Like Zoho, VT clearly wants to encourage business owners to upgrade to its advanced paid versions. Cash Book’s cheapest plan is VT Transaction+, which costs £85+VAT per year for a single user, and is MTD compliant and has invoicing features.

What support does VT Cash Book offer?

VT Cash Book is very limited when it comes to support features. Its only help channel is an online manual, compared to FreeAgent which offers both phone and email support during business hours.

Best accounting software with a free trial

All free accounting software comes with caveats and drawbacks, which is why it might be worth the extra few pounds to find an affordable, paid-for accounting software for your firm.

That’s why as well as free software, we also looked at paid accounting systems (the best self-employed accounting software as well) and the top contenders in both categories, so you can be certain about which you want to download.

Here are three of the most popular paid accountancy software programs on the market:

1. QuickBooks

QuickBooks is a cloud-based accounting software that’s specifically designed for UK SMEs. Our researchers named it the best accounting software overall, just behind FreshBooks (see our QuickBooks vs FreshBooks review for a closer comparison).

QuickBooks ticks all the standard boxes – income and expense tracking, the ability to submit VAT returns, and an invoice builder – but also has great features like a cash flow insights, and built-in integration for Construction Industry Scheme (CIS) deductions. All plans also come with reporting capabilities and 24/7 customer support.

When it comes to QuickBooks’ prices, there are three small business plans (and two more expensive plans which are better suited to larger businesses):

Alongside all the core accounting software features  – including invoice creation and Making Tax Digital VAT returns – Sage Business Cloud Accounting also has excellent support via phone and live chat.

Buying guide: How to choose the right free accounting software

Here are some key things you should consider when comparing providers:

• Check with your accountant (if you have one): if you do already work with an accountant, then it may be useful to get their input on what software is likely to work best for your business, and which works best with their systems.
• Choose your must-haves: regardless of the brand you choose, chances are you will have to compromise on free accounting software. Decide which of the bad points you can live with. We recommend going with a tool that allows you to submit a VAT return (such as Zoho Books).
• Take them for a spin: free accounting software is ideal for commitment-phobes. Simply sign up, input your data, and see how each feels. Many of the top paid accounting software providers also offer free trials, so you can see exactly what the extra outlay will give you in return.
