- Xero and QuickBooks are both strong software-only tools, with entry plans starting from around £16 a month before VAT.
- SleekBooks is included as standard with Sleek’s accounting plans, so you get the software and a dedicated accountant together from £60 a month.
- All three are Making Tax Digital ready, which matters because MTD for Income Tax begins in April 2026 for many sole traders and landlords.
Weighing up Xero vs QuickBooks vs SleekBooks? Choosing between Xero, QuickBooks and SleekBooks comes down to one question: do you want software only, or software with an accountant included?
Xero and QuickBooks are both excellent software-only tools, with entry plans starting from around £16 a month before VAT. SleekBooks takes a different route, bundling the software with a real accountant on Sleek’s plans, included as standard from £60 a month.
This guide compares all three fairly on price, ease of use, Making Tax Digital readiness and migration. You can also explore Sleek’s accounting services if you want the full picture first.
Xero, QuickBooks, SleekBooks: which is right for your UK business?
The right tool depends on what you actually need: software only, or software plus a human accountant. Choose Xero or QuickBooks if you want a self-serve platform and either already have an accountant or are happy to file yourself. Choose SleekBooks if you want the software and a dedicated accountant in one place.
Here is the quick version before we go deeper:
- Xero suits businesses that value a large app ecosystem and clean design.
- QuickBooks suits those who want strong reporting and a low entry price.
- SleekBooks suits founders who want software and filing handled together.
What is Xero, and who is it best for?
Xero is a cloud accounting platform built around bank reconciliation, invoicing and a very large third-party app marketplace. It is popular with UK small businesses and the accountants who support them, which makes finding Xero-friendly help easy.
Xero is best for businesses that rely on lots of integrations, such as inventory, e-commerce or payments tools. If you already work with an accountant who uses Xero, staying put often makes sense.
To see how the platform handles day-to-day tasks, our Xero accounting guide walks through the basics, and you can check current plans on the Xero UK pricing pages.
Entry pricing starts at roughly £16 a month before VAT for the Ignite plan, with higher tiers for payroll and multi-currency.
What is QuickBooks, and who is it best for?
QuickBooks is a cloud accounting tool known for strong financial reporting and a low starting price. It is widely used by UK sole traders and small limited companies, and it handles VAT and Making Tax Digital well.
QuickBooks is best for owners who want detailed reports and budgeting tools without a high monthly fee at the entry level. It also offers a sole trader plan aimed at the very smallest businesses, with full details on the QuickBooks UK site.
One thing to watch: QuickBooks raised UK prices across all plans in January 2026, so check the current rate before committing rather than relying on older figures.
What is SleekBooks, and who is it best for?
SleekBooks is Sleek’s own accounting software, and it comes with a dedicated accountant included as standard. That is the core difference: you are not just buying a tool, you are getting the software and the person who files for you in one package.
SleekBooks is best for founders and growing businesses that want compliance handled rather than managed themselves. If you have ever wondered whether you need software and an accountant, this model answers that question directly.
It is included on Sleek’s regular plan at £60 a month. Xero comes included as standard on Sleek’s pro plan at £100 a month, and regular-plan customers can add Xero on top without upgrading fully. These arrangements are handled case by case, so it is worth a quick conversation to find the right fit.
Before you pick a tool, write down whether you actually want to file your own returns. If the answer is no, a software-plus-accountant plan usually saves more time than it costs.
Price comparison (2026): what you’ll actually pay
Pricing is where the three differ most, because two are software only and one includes an accountant. The table below shows entry-level positioning. Always confirm live prices on each provider’s site, as software rates change.
Tool | Entry price (before VAT) | Accountant included? | Best for |
Xero | From around £16/month (Ignite) | No | App ecosystem and integrations |
QuickBooks | From around £16/month (Simple Start) | No | Reporting on a low entry budget |
SleekBooks | £60/month (Sleek regular plan) | Yes | Software plus filing in one |
The headline gap is not really £16 versus £60. With Xero or QuickBooks alone, you still need to file returns yourself or pay an accountant separately. Our guide to how much an accountant charges for self-assessment shows how those fees add up.
Software only, or software plus an accountant?
This is the real question behind most tool comparisons, and the answer depends on how much you want to handle yourself. Software-only tools like Xero and QuickBooks give you the platform but leave filing, deadlines and tax planning to you or a separate accountant.
A combined model bundles both. With SleekBooks you get the software plus a named accountant who files on your behalf, which removes the evening reconciliation burden many owners describe.
Use this simple test:
- Do you want to file your own VAT, accounts and tax returns? If yes, software only may be enough.
- Do you already have an accountant you trust? If yes, match the software to what they use.
- Do you want one provider for software and filing? If yes, a combined plan fits best.

Making Tax Digital: are all three ready for April 2026?
All three tools are Making Tax Digital compatible, so each can keep digital records and submit returns to HMRC. This matters now because Making Tax Digital for Income Tax begins in April 2026 for sole traders and landlords with qualifying income over £50,000.
That deadline turns software choice into a compliance decision, not just a preference. Whichever tool you pick, it needs to support digital record keeping and HMRC submission.
You can confirm the current rules and thresholds on the official Making Tax Digital guidance on GOV.UK.
For a plain-English overview, see our Making Tax Digital guide for small businesses.
Switching: how hard is it to move?
Moving between accounting tools is usually straightforward, though the effort depends on how much history you carry over. All three support importing core data such as customers, suppliers and the chart of accounts, typically from a spreadsheet.
The main work is reconciling opening balances and checking that VAT settings match. Where a provider handles migration for you, the switch is far easier. With Sleek, moving your books across is part of the onboarding, so you are not left untangling data alone.

The verdict: a simple decision table by business stage
The best choice maps cleanly to your stage and whether you want an accountant included. Here is the summary.
Your situation | Likely best fit |
Just starting, happy to DIY | Xero or QuickBooks entry plan |
Already use a Xero accountant | Xero |
Want strong reports on a budget | QuickBooks |
Want software plus an accountant | SleekBooks |
Growing team, outgrowing DIY | SleekBooks or a higher software tier |
Both Xero and QuickBooks remain genuinely strong picks if software alone is what you need. SleekBooks wins when you want the tool and the filing handled by one provider.
How Sleek helps with choosing accounting software
Sleek removes the hardest part of this decision by pairing software with a real accountant who files for you. SleekBooks is included on the regular plan, and Xero is available on the pro plan or as an add-on, so you are not forced into a tool that does not fit.
If you would rather not juggle software and a separate accountant, Sleek handles both, with migration done for you.

FAQs on Xero vs QuickBooks vs SleekBooks
Can I move my data from Xero to QuickBooks, or the other way round?
Yes, but it takes care. You can export customers, suppliers and the chart of accounts, though transaction history and reconciled bank data often need manual checking or a third-party migration tool. Many businesses move at the start of a new financial year to avoid splitting records mid-period. Reconciling opening balances accurately is the step most people underestimate.
Do Xero and QuickBooks handle payroll, or is that extra?
Payroll is usually a paid add-on rather than a standard inclusion. Xero charges per employee per month on top of most plans, and QuickBooks offers payroll as a separate tier. If you employ staff, factor this in, as the headline subscription price rarely covers it. Costs rise as your headcount grows.
Which tool is best if I sell on Shopify or Amazon?
Xero tends to lead here because of its large app marketplace and strong e-commerce integrations. QuickBooks also connects to major platforms but offers fewer niche apps. If your business depends on syncing sales, stock and fees automatically, check that your specific platform has a supported, well-reviewed connector before choosing.
Will the introductory discounts on Xero and QuickBooks last?
No. Both providers run heavy first-period discounts, sometimes up to 80 or 90 per cent off for the first few months, then revert to full price. Budget for the standard rate, not the promotional one. Anchoring to the intro price is a common reason owners feel caught out when the real monthly cost begins.
Is SleekBooks suitable for a sole trader, or only limited companies?
SleekBooks suits both, since the value is the included accountant rather than the company type. Sole traders benefit from having self-assessment handled, while limited companies get help with accounts and corporation tax. The right plan depends on your filing needs, so a short conversation usually clarifies the best fit.

Can my accountant access Xero or QuickBooks directly?
Yes. Both tools let you invite an accountant to collaborate in your account, usually at no extra cost. This is one reason they are popular, as it splits the work between you and a professional. With a combined plan like SleekBooks, that access is built in, since the accountant is already part of the service.
How long does it take to learn Xero or QuickBooks as a non-accountant?
Most owners get comfortable with the basics in a few hours, since both tools are built for non-accountants. Invoicing and bank reconciliation are quick to pick up, while reports and VAT settings take a little longer. The harder part is knowing what the numbers mean, which is where having an accountant helps.
