Your Time Is Better Spent Running Your Business
When you run a small company, every hour counts.
Spending evenings sorting receipts, worrying about Corporation Tax or trying to work out what needs filing next isn’t the best use of your time.
Simplex takes the accounting pressure away.
We’ll keep things organised, stay ahead of important deadlines and make sure you understand what’s happening with your finances.
That means less time dealing with financial admin and more time focusing on your customers, your work and where you want to take the business.
Accounting Essentials, All in One Place
You shouldn’t need different people for every part of your company’s finances.
Simplex provides the day-to-day and year-end accounting support small limited companies need, with advice tailored to the way your business actually operates.
We can help with:
✅ Annual accounts and Corporation Tax
✅ Bookkeeping and financial records
✅ VAT returns
✅ Payroll and director pay
✅ Tax planning and business advice
And if you’re unsure whether something applies to your company, just ask. We’ll explain it without the jargon.

“Simplex are super easy to work with. I love that I have a portal to track all documents and paperwork that need my attention. Everything else just seems to run in the background so I can focus on my business”

Know What’s Happening With Your Money
When you’re running a smaller company, knowing your numbers matters.
You need to understand what’s coming in, what’s going out, what you may owe in tax and what you can comfortably take from or reinvest into the business.
Simplex helps turn your accounts into useful information rather than something you only see at year-end.
We’ll help you understand how the business is performing and what the numbers mean, so you can make decisions with greater confidence.
Your Business May Be Small.
Your Ambitions Shouldn’t Be.
You shouldn’t have to become an accounting expert just because you run your own company.
Choose an accountant who can take care of the numbers, help you plan for tax and give you straightforward advice as your business develops.
With Simplex behind you, you can spend less time worrying about accounts and more time building the company you want.

“Simplex have been with our company from the start and are a crucial linchpin in our Operations. They are organised, methodical, quick to respond to needs and queries and ultimately professional while maintaining a friendly, caring approach. We couldn’t ask for more.”

Your Questions, Answered
We know you might have some questions, and we’re here to make everything as clear and straightforward as possible. If you need more information, don’t hesitate to reach out, we’re always happy to help!
The cost depends on how much support your company needs. Some businesses only need annual accounts and tax returns, while others want bookkeeping, payroll and regular help too. The important thing is knowing what you’re getting for your fee. We keep things clear and straightforward, so you know what’s included and what needs to be done. If you want to spend less time on accounts and more time running your business, we can help.
You do not legally need an accountant, but running a limited company comes with filing deadlines, tax returns and record-keeping responsibilities. It’s easy for these tasks to take up time or become stressful. We can handle the accounting side for you, keep everything organised and make sure you know what needs to happen next. That means fewer surprises, less admin and more time to focus on growing your business.
Yes, you can do your own limited company accounting, but you need to understand the rules, keep accurate records and meet the right deadlines. For many directors, the time spent learning and checking everything simply isn’t worth it. We can take care of the accounts, tax filings and day-to-day questions for you. You still stay in control of your business, without having to worry about whether everything has been done correctly.
For many small business owners, yes. An accountant can save you time, reduce admin and help you stay on top of tax and filing deadlines. More importantly, you have someone to turn to when you’re unsure about something. We work with small businesses and company directors remotely, keeping things simple and easy to understand. If you want reliable support without having to manage every accounting task yourself, having us on your side can make a big difference.
Yes, you can file your own limited company accounts, but you are responsible for making sure they are accurate and submitted correctly. This can become time-consuming, especially if accounting is not something you deal with every day. We can prepare and file your accounts for you, deal with the required tax filings and keep track of the deadlines. It gives you one less thing to worry about and helps keep your company in good order.
Common mistakes include poor record keeping, mixing personal and business spending, missing deadlines, claiming expenses incorrectly and leaving tax planning until the last minute. Many of these problems are easy to avoid when your accounts are kept up to date. We help business owners stay organised throughout the year, so there’s less rushing and fewer surprises. Having an accountant you can contact when questions come up can also make running your business much simpler.
