Why You Need Accounting Services

Any self-employed worker or business owner will understand how important accounting is in day-to-day operation. However, many will have zero experience with accounting and also lack the time to dedicate to it, which is why hiring professional accountants can be beneficial. By hiring a team of accountants, you can ensure an experienced team is handling your finances as well as freeing your time up for other important matters.  

So, while you are lightening your workload and freeing up your time, you are also benefitting from professional accountants handling your finances. Professionals can carry out work you won’t have experience with, and with financials, this is highly important, and everything needs to be handled correctly and legally.  

Additionally, hiring professional accountants can be beneficial for your company as they will offer advice and training too. Here at Mandair & Co, we are happy to provide training to your employees in various aspects of accounting, including bookkeeping. We also offer many online resources to assist you, such as income tax and national insurance calculators for the self-employed. 

As you can see from the above, there are many benefits to hiring professional accountants in Southampton, such as saving you time and ensuring financials are handled correctly.

While bookkeeping can seem like a dull task for many, it is extremely important in the day-to-day operation of your business. It is an essential aspect of accounting that needs to be carried out by all businesses in order to keep an eye on the accounts and make sure all financials are kept up to date. However, many business owners find they don’t have the time or the experience to carry this out and that they need to hire professional accountants to assist. 

This is where we come in at Mandair & Co, as we offer a dedicated bookkeeping service for our clients. We will be more than happy to consult with you and determine the type of bookkeeping work you need to carry out, and we can come up with a bespoke work schedule for you. Our team of accountants will always keep you up to date on the books and financials, ensuring you are aware of everything. 

However, in addition to handling the bookkeeping for you, we can also offer expert training for your own team. We want to make sure your employees have all the tools and knowledge they need to take on the bookkeeping services themselves, so we impart our own knowledge and experience. We also offer various software packages to assist, and training with the software too. 

Account Preparation

We understand that for many business owners, it can be difficult finding the time to prepare the accounts for audits and taxes. However, it is highly important that this aspect of accounting be carried out thoroughly, as your financials and accounts need to be in order and correctly prepared. This is where our team of chartered accountants come in, as we can handle the account preparation for you. Our team will make sure your company’s financial statements are correctly put together and fully prepared, leaving you with more time to focus on other aspects of the business. 

We understand that every business is different and, as such, the account preparation will need to be handled differently too. This is why we offer a bespoke service for every company, consulting with you to determine what preparation needs to be done. We will always ensure your accounts are in order, that they are presented in a way that is suitable for HMRC, and that they are sent off and filed on time. Plus, we will always keep you informed throughout the process, so you are always aware of what is happening with your accounts. 

Start Up Solutions 

Starting your own business is a daunting experience, especially when it comes to handling the financial aspect. You may find that you lack key experience in accounting, which is important to the success of any new business. For example, having a viable business plan is essential to success, and without one, you may find the business fails within the first year.  

To prevent this from happening and give your new business a higher chance of succeeding, you need to get business start-up advice from professionals. This is where we come in at Mandair & Co, as our Southampton accountants are on hand to offer this essential advice. We will offer advice on all aspects of your new business start-up and help you create a viable business plan too. 

Our service is tailored to your exact requirements and business, as we know that every company will be different. You can rely on us to help with various aspects of your accounting, from payroll and bookkeeping to budgeting, cash flow projections, and more. We will consult with you and establish your business goals before coming up with a plan that meets these requirements. Plus, we offer ongoing support and advice to ensure your finances are in order.  


Payroll is an essential aspect of any business, as it ensures your employees are paid the correct amount on time. However, many lack the knowledge or experience to handle payroll effectively, which is why it is always recommended to hire a professional accounting team to assist. This is where we come in at Mandair & Co, as we can handle your payroll for you.  

Our team of accountants have the knowledge and experience to effectively handle your payroll. We can organise everything, including ensuring your employees pay the right amount of tax and national insurance each month. Your payroll can be handled through PAYE, which takes care of taxes on a monthly basis for each employee, and we can handle any other elements too. 

Many companies use bonus payments and incentive schemes, as well as paying into a pension fund for each employee, and we can ensure this is all accounted for each month. We can also work with branded payslips for your company and other staff benefits. When you hire our team of Southampton accountants, you can rest assured knowing your employees will be paid the correct amount, on time, and with all tax, national insurance, and pension being accounted for. 

Tax Returns 

If you are self-employed, or you run your own business, filing annual tax returns will be a necessary but complicated part of your work life. Getting the accounts prepared and filing your tax returns can be confusing and daunting and, as it is a legal document, everything needs to be filled out correctly. Due to the complicated nature of filing, many choose to hire an accountant to handle it for them, which is where we can assist.  

We can take the hassle off your shoulders and handle your tax returns for you at Mandair & Co. Our team of chartered accountants will make sure your tax return is filed correctly on time, and that you are paying the right amount of tax.  

Plus, when you hire our professionals to handle your tax returns, you can even save money. Companies often overlook certain costs in areas when paying tax, ending up paying more than they need to. We can recognise these cost-saving areas when handling your taxes, ensuring you pay the legal minimum on your VAT and corporation tax.

Additional Services We Offer

Accountancy Firm Southampton

Here at Mandair & Co, we have chartered accountants in Southampton, and this means that we can provide other specialist services on top of our standard accounting services. These additional services include forensic accounting and tax investigation, and you can find out more about each of these below. 

Forensic Accounting

Forensic accounting has become an important area in accounting over the years, but many companies don’t have the knowledge or experience to carry this out. However, at Mandair & Co, we are chartered accountants who are fully qualified to carry out forensic accounting services.  

Forensic accounting is a specialist area of accounting that involves investigative accounting work, and this needs to meet the standards required by a court of law. It is an essential accounting service for companies that are facing legal issues and need to hire professionals to settle disputes.  

Our forensic accountants are highly experienced and qualified, and they have the knowledge required to deliver expert services. We can help resolve matters such as tax fraud, money laundering, and other financial accusations that may arise with your business. You can always expect the highest level of professionalism from our team as we are always highly vigilant and clinical.  

We will utilise our training to identify any anomalies in accounts, finding evidence to support or dispel claims of illegal activity.  

Tax Investigation 

A tax investigation is something HMRC can carry out at any time on your business to make sure you are paying the right amount of tax. During the investigation, they can look at any number of things, such as: 

  • The Tax You Pay 
  • Accounts and Tax Calculations 
  • Company Tax Return 
  • PAYE Records 
  • VAT Returns 

There are three levels of tax investigation; full enquiry, aspect enquiry, and random check. During a full enquiry, HMRC will review the entirety of your business. An aspect enquiry involves looking at a specific aspect of your accounts, and a random check is an investigation that can happen at any time. These investigations will involve an audit of your accounts, so it is essential that you keep your books up to date, and this is where we can help. 

At Mandair & Co, we can make sure your accounts are always up to date and correct, so if your company is investigated for any reason, everything is filed correctly and properly prepared.  

Our Resources 

Here at Mandair & Co, we aim to assist every client that needs accounting services and advice. This is why we can do more than offer our accounting services to clients in Southampton. We also offer many online resources you can take advantage of, which include: 

  • Income Tax Calculator 
  • Self-Employed Ready Reckoner 
  • Stamp Duty Land Tax Calculator 
  • Employee National Insurance Contribution Calculator 
  • Income Tax/National Insurance Contribution Calculator 
  • Company Car Calculator  

These calculators are all available online for you to use, allowing you to calculate and estimate various aspects of your financials. You can check that you are paying the correct amount of income tax, budget your self-assessment tax bill if you are self-employed, and work out how much SDLT you need to pay when buying or transferring land or property.  

You can also calculate your employee’s national insurance contributions when checking payroll calculations, estimate how much income tax and national insurance you can expect to pay and calculate the company car tax charge based on a car’s taxable value and CO2 rating.
