One of the most crucial decisions a company can make is which Accountant to hire. A good one can save time and help your company expand, whereas a bad one can cost you money.

This blog post will list a few essential tips before choosing an accountant and compile the top 50 Accountants in London, UK.

Why do you need an accountant?

While a few businesses attempt to handle everything independently, this is not the most effective method. The great majority of firms use a specialised accountant.

You can do many things without the help of a professional, but on the other hand, the time invested is usually not worth it to save a few dollars.

When you start contracting for a reasonable monthly cost, you can rely on a trained expert in all critical areas of accountancy, tax, and other financial concerns.

How to select the best Accountant

1. Fees
The first and most important consideration is your Accountant’s fees, which must fit within your business or personal budget. Every accounting company calculates their fees on an hourly or fixed-rate basis.

The total cost charged varies from one company to the next. Before signing a contract, talk about how much everything will cost.

2. Work experience
Because new/small businesses have very different needs and demands than huge organisations, it’s also good to pick an accountant who has demonstrated that they work successfully with your business type through their reference list.

Working with smaller accounting companies can sometimes mean getting a more personalised response to your questions.

3. Recommendations
Getting a referral from a colleague is always beneficial. Contact other accountants. You’ll quickly learn which ones to avoid and provide excellent service.

Changing accountants at a later date will be more accessible if you hire an accountant that uses an independent cloud-based accounting solution. And the firm you choose now might not be the ideal fit for you a few years later when your business grows.

4. Size of the firm
The number of clients handled by specialist accounting firms varies greatly, ranging from 200 to several thousand.

They will usually represent the kind of service in the figures. You should evaluate if you like a more “institutional” level of services, such as that provided by larger organisations, or a more personal level of service, such as a smaller firm.

For example, if you need partner-level phone support from the same person every time you call, you might be interested in going with a smaller company rather than a big one.

Find out what software the Accountant uses

Accountants commonly use accounting software. They’ve most likely been in business for many years and have adapted to a particular type of software.

It might be a problem. Data exchange may be a challenge if your firm uses a different type of software. Although data can be exported and imported in the correct format, this can be time-consuming and easily lead to mistakes.

Because email is about as secure as a postcard, there’s a chance that you will expose your private financial information while you send it back and forth. As a result, look for an accountant who works with the same accounting software that you do.

What if your Accountant does a bad job?

You’ve followed all the rules and chosen your Accountant with care. But you’ve never had an accountant before; how do you know whether they’re doing a good job? And what happens if they aren’t?

You can effectively sack an accounting firm by simply telling them you no longer want to cooperate. But don’t hurry into it; having a working relationship with your Accountant is crucial. If you change every six months, this is challenging.

Look at the results you’re getting from them. Are your accounts and tax returns prepared on time, at the most basic level? Are your bills being sent on time, and are your phone calls and letters returned? Then, on top of that, paying attention to what they’ve told you is essential.

You may typically resolve problems by better communication and setting KPIs, so keep a close eye on the service and contact your Accountant if necessary. But remember that you aren’t paying for poor service.
