Sage vs FreeAgent UK: Which Is Right for Your Business?
FreeAgent is the better choice for most UK sole traders, contractors, and single-director limited companies in the Sage vs FreeAgent UK comparison, particularly if you bank or are willing to bank with NatWest, RBS, or Mettle, where it costs nothing. Sage Accounting suits businesses that need stronger stock management, broader third-party integrations, or whose accountant already works in Sage.

Sage vs FreeAgent: the verdict up front
For the audience this comparison is aimed at, the choice is usually straightforward. If you are a freelancer, contractor, or single-director limited company, FreeAgent does everything you need, files your Self Assessment return directly, and can cost you nothing if you bank with NatWest, RBS, Ulster Bank, or Mettle. Sage Accounting is a more capable platform in certain areas, but most of those areas do not apply to a one-person business.
Sage makes more sense if your accountant specifically works in Sage, if you carry stock, or if you need integrations with platforms like Shopify or Salesforce. For everyone else in this audience, paying £30 a month for Sage’s standard plan is hard to justify when FreeAgent matches it on the features that matter most.
Pricing: FreeAgent’s free bundle is the decisive factor
FreeAgent’s paid plans cost £19 a month for sole traders, £27 for partnerships, and £33 for limited companies, all excluding VAT. A landlord plan is available at £10 a month. FreeAgent routinely offers 50% off for the first six months, so the first half-year is considerably cheaper than the headline rate.
The more important number for many readers is £0. FreeAgent is free for as long as you hold a NatWest business current account, an RBS business current account, or an Ulster Bank business current account. With Mettle, NatWest’s digital business bank, it is also free, but you must make at least one transaction per month through the Mettle account to maintain access. That condition is easy to overlook, so it is worth building it into your routine. Mettle is open to sole traders and limited companies only, not partnerships, and does not offer overdrafts or multi-currency banking.
A few optional add-ons carry extra charges even on the free bundle. The Smart Capture receipt scanning tool and the Amazon UK Marketplace connector (around £6 a month) are the most notable. The free access is genuinely free, but do not assume every feature is included automatically.
Sage Accounting is structured differently. The entry-level Sage Accounting Start plan costs around £15 a month, but it does not include VAT returns, which makes it too limited for most businesses. The standard Sage Accounting plan, which adds VAT, cash flow, and payroll for one employee, costs around £30 a month. The Sage Accounting Plus plan, which adds multi-currency, stock management, and more advanced reporting, is around £49 a month. Sage runs promotional deals regularly, including three-months-free and 50%-off introductory offers, so check the current offer at sage.com before signing up. There is no free bank-bundle option.
For a sole trader who banks with NatWest or Mettle, the pricing comparison is not close. For someone with no intention of switching banks, FreeAgent at £19 a month versus Sage at £30 a month is still a meaningful gap, and FreeAgent includes features that Sage does not.
Invoicing: both are solid, FreeAgent feels more natural
Both platforms let you create and send professional invoices, chase late payments automatically, and reconcile payments against bank transactions. FreeAgent’s invoicing interface is generally regarded as more intuitive for non-accountants. You can set up recurring invoices, add expense lines, and track time against projects all within the same tool, which makes it well suited to contractors who bill by the hour or project.
Sage’s invoicing is capable and covers the same ground, but it sits within a broader interface that can feel more complex if you only need the basics. For tradespeople and contractors who want to raise invoices quickly and move on, FreeAgent’s approach tends to win. If invoicing software is a priority in its own right, see our guide to the best invoicing software for tradespeople for a wider comparison.
Bank feeds: both work well, Mettle is seamless
FreeAgent connects to most UK business bank accounts via Open Banking and imports transactions automatically. If you use Mettle, the integration is closer still — the two products are built by the same group and the feed is effectively native. Transactions flow through without the occasional re-authentication that Open Banking connections sometimes require.
Sage also uses Open Banking and connects to the main UK business banks reliably. The experience is broadly similar across the two platforms for most banks. The practical edge goes to FreeAgent if you use Mettle, and is roughly equal everywhere else.
MTD and VAT: FreeAgent includes it on all paid plans, Sage holds it back
Making Tax Digital for VAT is available on all FreeAgent paid plans, including the sole trader plan at £19 a month. That is a meaningful advantage over Sage, where MTD VAT support is only available from the standard plan upward. If you signed up to Sage Accounting Start to save money, you would not be able to file VAT returns through the software, which defeats the purpose for most VAT-registered businesses.
Both platforms are HMRC-recognised for the MTD for Income Tax Self Assessment pilot, which will become mandatory for many sole traders and landlords from April 2026. Either product will allow you to submit quarterly updates to HMRC under the new rules once they apply to you.
Self Assessment and corporation tax: FreeAgent’s biggest practical advantage
FreeAgent files Self Assessment SA100 returns directly from the platform. You enter your income and expenses throughout the year, and at the end of the tax year you can submit your return to HMRC without leaving the software or paying an accountant to do it separately. For sole traders and contractors who do their own Self Assessment, this is a genuinely useful feature that saves time and money.
Sage does not file Self Assessment returns from its accounting software. You would need to export your figures and file through HMRC’s own system, or use a separate tool, or hand the job to an accountant. That is not a dealbreaker if you use an accountant anyway, but for the self-filing contractor or freelancer it is a real gap.
On corporation tax, neither platform files the CT600 return directly from its core product. If you run a limited company and need to handle corporation tax yourself, you will need a separate tool or professional help. Our guide to the best corporation tax software for UK businesses covers the main options.
Ease of use: FreeAgent is simpler, Sage has more depth
FreeAgent has won the Institute of Certified Bookkeepers Luca Award for Friendliest Software of the Year in 2022, 2023, 2024, and 2025. That track record reflects a genuine design philosophy: the software is built for business owners who are not accountants, and it shows. The dashboard gives you a clear view of what you owe, what you are owed, and your tax liabilities without requiring you to understand double-entry bookkeeping.
Sage Accounting is more capable in some areas, but that capability comes with more complexity. The interface has improved in recent years, and it is far from unusable, but a sole trader logging in for the first time will generally find FreeAgent easier to navigate. Sage’s depth makes more sense once you have staff, stock, or multiple integrations to manage. For a tradesperson looking for straightforward accounting software, FreeAgent’s simplicity is a practical advantage.
Who should choose FreeAgent
FreeAgent is the right choice if you are a sole trader, freelancer, contractor, or single-director limited company who wants software that handles day-to-day bookkeeping, invoicing, and Self Assessment in one place. It is especially strong if you bank or are willing to bank with NatWest, RBS, Ulster Bank, or Mettle, where you get full access for free. Northern Ireland-based readers should note that Ulster Bank business accounts also qualify for the free bundle. FreeAgent suits people who want to manage their own tax affairs without an accountant, and who value a clean, approachable interface over a wide feature set.
Who should choose Sage
Sage Accounting is the better fit if your accountant already uses Sage and wants you on the same platform, if you carry stock that needs tracking, or if you need integrations with Shopify, Salesforce, or other third-party tools. It is also worth considering if you run a small team and want payroll, multi-currency, and more advanced reporting under one roof. The standard plan at around £30 a month is competitive for what it offers once those requirements apply to you — just be aware that the Start plan at £15 a month is too stripped back for most VAT-registered businesses.
| Tool | Price (excl. VAT) | SA100 filing | Best for |
|---|---|---|---|
| FreeAgent Top pick | £19/mo sole trader; £0 with NatWest/Mettle | Yes — files directly | Sole traders, contractors, single-director LTDs |
| Sage Accounting Start | ~£15/mo | No | Very basic use only — no VAT |
| Sage Accounting | ~£30/mo | No | SMEs needing stock, integrations, or Sage-familiar accountant |
| Sage Accounting Plus | ~£49/mo | No | Businesses needing multi-currency and stock management |
Head-to-head comparison
On price, FreeAgent wins outright for anyone banking with NatWest or Mettle, and still wins on value for most sole traders at full price when Self Assessment filing is factored in. Sage’s Start plan looks cheaper on paper, but the absence of VAT returns makes it unusable for most VAT-registered businesses, pushing the real comparison to the £30-a-month standard plan.
On tax filing capability, FreeAgent has a clear edge. Filing your SA100 directly from the software without a separate step or an accountant is a tangible time and cost saving. Sage directing you elsewhere for Self Assessment is not a flaw for a business using an accountant, but for the self-filing contractor it removes a key reason to pay for accounting software in the first place.
On MTD readiness, both platforms are HMRC-recognised and will handle quarterly reporting under MTD for Income Tax when it becomes mandatory. The difference is that FreeAgent includes VAT MTD on all plans, while Sage limits it to standard and Plus. That distinction matters if you are tempted by Sage Start.
On ease of use, FreeAgent is the more approachable platform and that assessment is backed by independent awards over four consecutive years. Sage has improved, and its greater depth suits more complex businesses, but for a sole trader who wants to log in, raise invoices, and check their tax position quickly, FreeAgent’s interface is less likely to get in the way.
On integrations and stock, Sage wins. If your business uses Shopify, Salesforce, or needs inventory tracking, Sage Accounting or Sage Accounting Plus is the more capable tool. FreeAgent is not designed for that kind of complexity and does not try to be.
Alternatives worth considering
Xero is the other major name in this space and deserves a mention. It sits broadly between FreeAgent and Sage in complexity and price, offers strong bank feeds, and has a large accountant user base in the UK. It does not match FreeAgent’s Self Assessment filing or the free bank-bundle deal, but it handles multi-currency from its standard plan and integrates with a wide range of tools. Worth looking at if neither FreeAgent nor Sage feels right.
QuickBooks Self-Employed is worth considering for sole traders who want something even simpler than FreeAgent and primarily need mileage tracking, expense categorisation, and an estimate of their tax bill. It does not match FreeAgent’s invoicing or MTD capability, but at a lower price point it suits very low-complexity freelance businesses.
Bokio is a smaller UK-focused option aimed at sole traders and small limited companies, with a free plan that covers basic bookkeeping. It lacks the polish and feature depth of FreeAgent or Sage, but if budget is the only consideration and you do not qualify for the free NatWest bundle, it is a reasonable starting point.
Verdict
FreeAgent is the right answer for the majority of sole traders, contractors, and single-director limited companies reading this comparison. The free access via NatWest, RBS, Ulster Bank, and Mettle removes the pricing decision entirely for many people, and the direct Self Assessment filing is a genuine differentiator that Sage cannot offer. Sage Accounting earns its place for businesses that have grown past FreeAgent’s scope, particularly those with stock to manage, a Sage-familiar accountant, or a need for more integrations. Start with FreeAgent and only revisit Sage if your requirements outgrow it.
Frequently asked questions
Is FreeAgent really free with NatWest?
Yes. FreeAgent is free for as long as you hold a NatWest business current account, with no time limit attached. The same applies to RBS and Ulster Bank business accounts. With Mettle, NatWest’s digital bank, it is also free but requires at least one transaction per month through the Mettle account. Some optional add-ons, such as the Smart Capture receipt tool and the Amazon Marketplace connector, carry extra charges even on the free bundle.
What is the difference between Sage Start and Sage Accounting?
Sage Accounting Start is the entry-level plan at around £15 a month and covers basic invoicing and bank reconciliation, but it does not include VAT returns. Sage Accounting, the standard plan at around £30 a month, adds VAT filing, cash flow tools, and payroll for one employee. Most VAT-registered businesses will need the standard plan as a minimum, making Start largely unsuitable for the majority of small businesses.
Can FreeAgent file a Self Assessment tax return?
Yes. FreeAgent lets you complete and submit your SA100 Self Assessment return to HMRC directly from within the software. This is one of its strongest advantages over Sage, which does not offer direct Self Assessment filing and requires you to use HMRC’s own portal or an accountant instead.
Does Sage Accounting support Making Tax Digital?
Sage Accounting supports MTD for VAT on its standard and Plus plans, not on the Start plan. Both Sage and FreeAgent are HMRC-recognised for the MTD for Income Tax Self Assessment pilot, which will become mandatory for many sole traders and landlords from April 2026.
Is FreeAgent good for limited companies?
Yes, FreeAgent has a dedicated limited company plan at £33 a month, which includes payroll, dividend recording, and the tools a single-director company typically needs. It does not file the CT600 corporation tax return directly, so you will still need a separate tool or accountant for that. If you bank with NatWest or Mettle, the limited company plan is also available free.
Can I use FreeAgent without a NatWest account?
Yes. FreeAgent is available as a paid standalone product for £19 a month for sole traders, £27 for partnerships, and £33 for limited companies, all excluding VAT. The NatWest, RBS, Ulster Bank, and Mettle free bundles are an option but not a requirement.
Which is easier to use, Sage or FreeAgent?
FreeAgent is generally considered easier to use for non-accountants. It has won the Institute of Certified Bookkeepers Luca Award for Friendliest Software of the Year four years running, from 2022 to 2025. Sage’s interface has more depth, which suits more complex businesses, but for a sole trader or contractor wanting straightforward bookkeeping it adds unnecessary complexity.
Does FreeAgent do payroll?
Yes. FreeAgent includes payroll on all its paid plans and as part of the free bank-bundle access. It handles RTI submissions to HMRC, payslips, and basic payroll management. It is suited to small teams rather than businesses with complex payroll needs.
Both Sage and FreeAgent are credible, well-supported products, and either will serve a small UK business reliably. For most sole traders and contractors, FreeAgent’s pricing and Self Assessment filing make the decision easy.
