Do you still need an accountant if you use Xero or FreeAgent?

Modern accounting software makes it easier than ever to stay on top of your finances. If you’re using platforms such as Xero or FreeAgent, you might be wondering: do you still need an accountant?

It’s a fair question. Both platforms can generate invoices, chase payments, connect to your business bank account, record expenses, submit VAT returns and help you prepare your accounts for tax.

However, while accounting software handles many day-to-day bookkeeping tasks, it doesn’t replace professional advice, particularly as your tax affairs become more complex.

Here’s a practical look at what Xero and FreeAgent do well, where they fall short, and whether you can safely go it alone or still benefit from having an accountant.

What Xero and FreeAgent can handle on their own

Let’s start with what both platforms are designed to do:

Send and track invoices
Connect to your business bank account and match transactions
Log expenses and upload receipts
Run profit & loss and balance sheet reports
Track mileage and time
Manage payroll (if set up correctly)
Submit VAT returns (if you’re signed up for MTD)

They also do a decent job of flagging deadlines and generating useful overviews, especially if you check them regularly.

Compare Xero or try FreeAgent, which offers ByteStart readers a 30-day free trial plus 10% off for life.

So do you still need an accountant?

It depends on a few things – mainly how complex your finances are, and how confident you are about the tax side of things.

If you’re a sole trader with one income stream, no employees, and you’re comfortable with Self Assessment, you might manage fine without an accountant. But even then, you could be missing out on tax-saving opportunities.

And if you run a limited company, have multiple income sources, claim things like capital allowances or pensions, or deal with VAT, it’s usually worth having someone who knows what they’re doing check it all over.

What software doesn’t do (yet)

Here’s where software can’t fully replace a human:

Advising on the most tax-efficient way to take income
Spotting when you’re eligible for reliefs or allowances
Helping you plan for future tax bills or company changes
Checking for errors before you file
Dealing with HMRC enquiries or disputes
Helping you decide when to register for VAT or change business structure

These are the kinds of things a good accountant will look out for — and the kind of value that’s easy to overlook until something goes wrong.

Could you just hire one for year-end only?

This is a popular compromise. You do the day-to-day bookkeeping in Xero or FreeAgent, then bring in an accountant to review everything before filing, just to check you haven’t made any obvious mistakes.

You’ll usually pay a one-off fee, and it’s far cheaper than full monthly packages. But make sure your records are tidy — no accountant wants to untangle a year’s worth of mismatched transactions for a bargain price.

How to get the best of both worlds

Many accountants now include Xero or FreeAgent as part of their service, so you don’t necessarily have to choose between software and professional advice. In fact, many encourage clients to use cloud accounting software because it makes collaboration much easier.

This means you can upload receipts, track your income, and keep your books up to date – while your accountant steps in when it’s time to file your tax return or advise on bigger-picture decisions.
