FreeAgent is designed around UK freelancers, contractors and small businesses: Self Assessment, VAT and Corporation Tax workflows that match how HMRC works. NatWest, RBS, Ulster Bank and Mettle customers get it free with business accounts.
It is unapologetically British, which is perfect for its audience and irrelevant elsewhere. UK micro-businesses should check their bank bundle first.
FreeAgent users should check their bank's partnership page before paying; free access through NatWest, RBS or Mettle is common. Complete the tax timeline setup for your business structure on day one. The dividend and salary guidance for limited companies is genuinely useful.
What we like- Built for UK tax
- MTD compliant
- Often free via business bank accounts

KashFlow keeps UK small business bookkeeping simple: invoicing, VAT, payroll and MTD compliance without the learning curve of bigger platforms. Now part of IRIS Software Group, it has stability behind it.
The ecosystem is smaller than Xero's or QuickBooks'. Businesses that want straightforward UK accounting without fuss find it comfortable.
KashFlow users should set up VAT and payroll together during onboarding to avoid reconfiguring later. The IRIS backing means stability, so commit confidently. Keep the chart of accounts simple; complexity can be added as you grow.
What we like- Simple UK-focused bookkeeping
- MTD for VAT
- Payroll available
Watch out for- Fewer integrations than Xero
- Interface less modern

Clear Books is independent UK accounting software with VAT, payroll and Making Tax Digital support. Users praise the transparent pricing and the human customer service.
International businesses and those needing deep integrations may prefer Xero. UK small businesses wanting a domestic vendor with honest pricing should shortlist it.
Clear Books customers get the most from the transparent pricing by reviewing the plan annually against actual usage. The customer service reputation is earned, so use it during setup. Confirm MTD compatibility for each tax obligation you hold.
What we like- UK-built with MTD support
- Clear pricing
- Good customer service reputation
Watch out for- Smaller app marketplace
- Less known internationally

Xero is enormously popular with UK accountants, which means advice and support are easy to find. MTD for VAT and Income Tax Self Assessment are covered, and the integration marketplace is the deepest available.
Costs add up across tiers and add-ons. For growing businesses that want the platform their accountant recommends, Xero is the safe pick.
Xero users in the UK should connect their accountant as an advisor user immediately; collaboration is the platform's strength. Set up bank rules for recurring transactions to speed reconciliation. Review the app marketplace only when a real need arises.
What we like- Huge UK accountant network
- MTD compliant
- 1,000+ integrations
Watch out for- Pricing in GBP rises with tiers
- Payroll via partners

QuickBooks Online's UK edition covers MTD, VAT and payroll with the backing of the world's largest small business accounting brand. Feature depth is excellent.
The interface has grown complex and pricing climbs through tiers. Businesses planning international growth value the global consistency.
QuickBooks UK users should verify MTD for VAT is enabled and tested before the first filing deadline. The UK edition differs from the US one, so follow UK-specific guidance. Link payroll carefully, checking RTI submissions in the first month.
What we like- Global standard with UK edition
- MTD compliant
- Broad feature set
Watch out for- Interface complexity
- Tier pricing

Sage is the grand old name of British accounting software, and Sage Business Cloud Accounting brings MTD-compliant bookkeeping to small businesses. Accountant familiarity is near-universal in the UK.
The product lineup can confuse buyers, and the experience feels less modern than Xero. Buyers who trust established British brands stay comfortable.
Sage UK buyers should identify exactly which Sage product fits before subscribing; the lineup confuses even accountants. Business Cloud Accounting suits most small businesses. Ask your accountant for their preferred edition.
What we like- British heritage
- Trusted by generations of accountants
- Solid UK payroll
Watch out for- Product range confusing
- Cloud UX trails rivals

Crunch bundles online accounting software with actual accountants for a fixed monthly fee, aimed at UK freelancers, contractors and small businesses. Limited company owners get software, bookkeeping support and tax advice in one.
It costs more than pure software because it includes a service. Freelancers who want an accountant on call without surprise bills find the model compelling.
Crunch clients should use the accountant access proactively; the fixed fee covers advice you would otherwise pay hourly for. Keep records current in the software so the accountants can work efficiently. The model suits contractors who dislike admin.
What we like- Software plus human accountants
- Fixed monthly fee
- Built for UK freelancers
Watch out for- Service model, not pure software
- Costs more than DIY tools

Zoho Books brings its generous free tier and low-cost plans to the UK with MTD for VAT compliance. Cost-conscious businesses get capable accounting for little or nothing.
UK-specific depth trails the domestic vendors, and fewer British accountants recommend it. For the price, the value is hard to argue with.
Zoho Books UK users should confirm MTD for VAT support is active for their specific obligations. The free tier is enough to evaluate properly. Connect a UK bank feed early to test the core workflow.
What we like- Free tier
- MTD for VAT support
- Affordable paid plans
Watch out for- Smaller UK accountant network
- Ecosystem thinner locally

AccountsPortal offers simple online accounting for UK small businesses: invoicing, expenses, VAT and reporting at a low price. Businesses that find Xero overwhelming get the essentials without noise.
It is a smaller vendor with a thinner integration ecosystem. For basic UK bookkeeping at minimal cost, it does the job.
AccountsPortal users should keep expectations aligned with the price: solid basics, modest extras. The simplicity suits businesses that find larger platforms overwhelming. Export data regularly as good practice.
What we like- Simple and affordable
- UK-focused
- Straightforward invoicing and VAT
Watch out for- Smaller vendor
- Fewer integrations
How we chose
We verified each vendor's homepage and kept tools with genuine UK capability: MTD support, UK payroll or a real British user base. We excluded US-only tools without UK tax handling. Free plan status comes from vendor sites.
What to get right before you buy
Confirm MTD compatibility for your taxes. Making Tax Digital now covers VAT and is extending to Income Tax Self Assessment; your software must support your obligations.
Ask your accountant. UK accountants have strong preferences, and their recommendation usually reflects what they can support efficiently.
Check payroll needs. RTI payroll is separate from bookkeeping; confirm whether your tool includes it or needs an add-on.
Frequently asked questions
What is Making Tax Digital?
HMRC's requirement to keep digital records and file VAT and Income Tax returns through compatible software. Your accounting tool must be MTD-compatible.
Which accounting software is best for UK freelancers?
FreeAgent and Crunch are built for UK freelancers; FreeAgent is software while Crunch bundles accountants. Check bank bundles for free FreeAgent access.
Is Xero or QuickBooks better in the UK?
Both are MTD-compliant with large UK accountant networks. Xero is often praised for design and integrations; QuickBooks for feature depth. Ask your accountant.
Can I use US accounting software in the UK?
Only if it supports UK VAT, MTD and payroll. Most US tools have UK editions; verify MTD compatibility rather than assuming it.
How much does UK accounting software cost?
From free (Zoho Books tier, bank-bundled FreeAgent) to 15-40 per month for standard plans, plus payroll add-ons. Crunch-style bundles cost more but include accountants.
Do I need an accountant with accounting software?
Software records; accountants advise on tax, dividends versus salary, and year-end. Most limited companies benefit from both.
Making Tax Digital without the panic
Making Tax Digital trips up UK businesses that leave it to the last minute. Start by listing every MTD obligation you hold: VAT, Income Tax Self Assessment, and soon Corporation Tax. Each needs compatible software and digital record-keeping from the start of the relevant period, not from the filing deadline.
Next, go digital before you are forced to. Businesses that switch to MTD-compatible software a full quarter early file their first digital return calmly; businesses that switch the week before face stress and errors. The software needs time to learn your patterns, and you need time to learn the software.
Then, understand what digital records actually require. Every transaction needs a digital trail from source to return: invoices, receipts and bank feeds captured electronically. Paper records photographed into the app count, but shoeboxes do not. Build the capture habit now.
Check your bridging position honestly. Spreadsheets with bridging software technically comply, but they preserve manual processes that MTD was meant to replace. Proper accounting software costs little more and removes the monthly bridging scramble.
Finally, use your accountant as an MTD ally. They file for hundreds of clients and know where the pitfalls are. A thirty-minute conversation about your obligations beats hours of HMRC guidance reading. The penalty regime is real but entirely avoidable with modest preparation.
Switching accounting software mid-year
Switching mid-year feels risky, but the best time is often now rather than next January. Start by choosing a cutover date, usually a month-end or quarter-end, and run both systems in parallel for one period. The parallel run catches setup errors before they matter.
Migrate opening balances carefully, not every historical transaction. Bring over customer and supplier balances, bank balances, and outstanding invoices as of the cutover date. Full history migration sounds appealing but usually imports years of miscategorized data. Keep the old system read-only for reference.
Reconcile everything at cutover. Bank accounts, VAT control, payroll liabilities: every balance should tie between old and new. Differences found now are easy to fix; differences found at year-end are not.
Retrain yourself on the new workflows before the parallel period ends. Invoicing, expense capture, bank reconciliation and VAT filing all work slightly differently. A week of deliberate practice prevents months of frustration.
Finally, tell your accountant about the switch. They may have template charts of accounts, preferred settings, or integration advice that saves hours. An accountant who supports the new platform is worth more than any feature difference.
