Xero vs QuickBooks vs Sage: All Three Compared

First: which Sage? #

Sage sells two different things under names close enough to be mistaken for each other, and only one of them competes with Xero and QuickBooks.

	Sage Accounting	Sage 50
What it is	Cloud, in a browser	Desktop software installed on Windows
Competes with	Xero and QuickBooks	Older desktop accounting
Access	Any device, plus a mobile app	The machine it is installed on
Reporting	Standard reports	More report templates
On this page	Yes, this is what is compared below	No

If someone quoted you "Sage", ask which product. A Sage 50 licence and a Sage Accounting subscription are different purchases with different prices and different working patterns. Comparisons that just say "Sage" are usually mixing the two, and a quote for one tells you nothing about the other.

Price, all three #

	Cheapest plan	Dearest plan	Introductory offer
QuickBooks	£10.00	£56.00	Discounts of 50% to 90% for the first 3 to 6 months are frequent
Xero	£18.00	£70.00	90% off for the first 6 months for new customers
Sage Accounting	£20.00	£59.00	90% off for the first 6 months, so £2 a month before it reverts

All three discount the first six months heavily, and the discount is not what you are buying. Every figure above is the list price you pay from month seven. A plan advertised at £2 is £20.00 after the offer ends, and you will be on it far longer than six months.

A note on sourcing. The Xero figures come from Xero's own pricing page. QuickBooks loads its prices through JavaScript and Sage's pricing page blocks automated requests, so those two sets come from secondary reporting and should be confirmed on QuickBooks and Sage before you rely on them.

What each one charges you more for #

This matters more than the headline price, because the three vendors meter completely different things. Whichever axis your business grows along decides which gets expensive.

Adding more	QuickBooks	Xero	Sage Accounting
People who log in	Costs more, 3 then 5	Not directly	Unlimited from the middle plan
Invoices you send	No limit	Costs more, entry plan capped	No limit
Employees on payroll	Included from Essentials	Costs more, built into the tiers	Priced separately
CIS handling	Included from the cheapest plan	Add-on	Varies by plan
Stock and multi-currency	Top plan	Upper plans	Top plan

Which to pick #

Construction, or anything with CIS: QuickBooks. CIS on invoicing from £10.00 a month is the clearest single advantage on this page
Six or more people needing access: Sage Accounting, where users stop costing extra
High invoice volume, small team: QuickBooks or Sage. Xero's entry plan caps invoices, which is the one limit people hit without expecting to
You want a wide app ecosystem: Xero, comfortably
Payroll for a few staff: QuickBooks or Xero, where it is bundled. Sage prices it apart, so compare the combined figure
Your accountant has a preference: take it. Working against your accountant's platform usually costs more than the price difference saves

Check the reverse charge, not just CIS. Most construction subcontractors are inside the VAT domestic reverse charge, which changes the invoice wording and the VAT return boxes. Software that handles CIS does not automatically handle the reverse charge properly. Raise one real invoice during the trial and check it.

The one that beats all three on price #

FreeAgent is free outright with a NatWest, RBS, Ulster Bank or Mettle business account. If you bank with one of those, or would move, that undercuts everything on this page and is worth checking before you pay for anything.

What it costs and the exact terms of that offer are on the FreeAgent page. It is also covered in FreeAgent vs Xero and FreeAgent vs QuickBooks, and the sole trader comparison puts the lighter options together.

Two at a time #

If you have already ruled one out, the head-to-head pages go into more detail than a three-way can:

And if all you need is to raise a compliant invoice, the invoicing software comparison covers the free end of the market, while the invoice generator needs no subscription at all.

Common questions #

Which is best: Xero, QuickBooks or Sage?

None of them universally. QuickBooks is cheapest to start at £10 and includes CIS. Sage gives unlimited users from its middle plan. Xero has the widest app ecosystem. The right answer depends on whether you are adding invoices, people or integrations.

Xero, QuickBooks or Sage: which is cheapest?

QuickBooks, at £10 a month for its entry plan, against £18 for Xero and £20 for Sage. At the top of each range they converge. Compare the price in month seven, not the introductory offer.

Is Sage 50 the same as Sage Accounting?

No, and this is the most common confusion. Sage 50 is desktop software installed on Windows. Sage Accounting is the cloud product that competes with Xero and QuickBooks. Most "Sage" comparisons online quietly mix the two.

Which handles CIS best?

QuickBooks, which includes Construction Industry Scheme handling on invoicing from its cheapest plan. Xero offers CIS as an add-on. Sage varies by plan and product. For a construction business that difference usually outweighs the price.

Which is best for a sole trader?

QuickBooks on price, at £10. But check FreeAgent first: it is free with a NatWest, RBS, Ulster Bank or Mettle business account, which beats all three of these outright if you bank with one.

Can I move between them?

Yes. All three support migration and conversion services exist, including for a QuickBooks to Xero conversion UK businesses commonly do. The practical constraint is your accountant, since most practices standardise on one platform.

Are all three Making Tax Digital compatible?

Yes. All three are HMRC-recognised for Making Tax Digital for VAT and file returns directly. Treat MTD compatibility as a baseline rather than a reason to choose any of them.
