The Services We Offer  

As mentioned above, we at Mandair & Co can provide small businesses with a wide range of accounting services, such as help with VAT, business analysis, forensic accounting, and help with tax investigations. 

Account Preparation  

Running any business is a full-time commitment which is where our account preparation service comes in. Speak to our accounting team, and we’ll make sure your accounts and annual returns are made ready on time, ready for submission to the HMRC and Companies House. 


Nobody likes bookkeeping; unless you’re our accounting team, then you love it. We provide access to cutting-edge software packages to help you keep on top of your company’s bookkeeping. We’ll even train you and your team in the use of the software, making the whole process hassle-free. 

Business Start-Up  

We’ve focused on this a lot in this article, but it’s worth reiterating that we’re here to assist small business start-ups with getting their finances in order. This includes cash flow projections, budgeting, financial planning, establishing pension schemes, payroll, and preparing HMRC/ Companies House submissions. 


A workforce needs to be paid, and the ability to pay your employees on time and in full we’ll make for a happy workforce. We can handle your payroll, from the administration of PAYE, national insurance, and sick pay to bonus payments, incentive schemes, staff benefits, maternity/ paternity pay, etc. 

Tax Returns  

Besides accountants, very few people actually enjoy submitting tax returns, yet they are a legal requirement. If you’re not paying enough tax or paying on time, you could face financial penalties or even prison time. Likewise, you could be paying too much tax. Our accounting team will ensure your tax returns are prepared and submitted on time and that you’re paying only what you need to. 

Business Analysis  

If you’re looking to introduce and manage a change to your business, you’ll need to go through a process known as business analysis. This is a disciplined approach in which our accounting professionals identify and articulate ways to bring about a much-needed change to how the company operates. This can have positive benefits financially. 


Most businesses operate by selling products or services. Virtually any item or service that’s sold is subject to Value Added Tax. This is usually calculated based on the value of the product or service. All businesses must wrangle with VAT, and, for some, this can be a constant headache. Fortunately, our accounting team can take of this headache for you. 

Tax Investigation  

If you suspect that you’ve been paying too much tax or not enough tax, you’ll need to request a tax investigation. Such an investigation is usually carried out by the HMRC, who will look at your tax payment history. To ensure you’re ready for a tax investigation, our accounting team will go over your books from top to bottom and identify any problem areas. 

Forensic Accounting  

Often, businesses will be faced with a predicament where money has gone missing and cannot be located. This could be a simple accounting error or a sign of foul play. Whatever the situation might be, the most effective way to track down and recover the missing money is through forensic accounting. We can do this for you and even provide financial findings as evidence along with expert testimonial. 

We Are ICAEW Chartered Accountants  

As officially recognised ICAEW chartered accountants, small business owners can fully trust us to provide the most dependable accounting services possible. All our chartered accountants are fully regulated with their conduct and performance actively monitored. We’re authorised to provide small businesses with a wide range of accounting services. All accountants are responsible and fully accountable, providing members of the public with complete peace of mind. 

What is an ICAEW Chartered Accountant  

We are proud to be associated with the Institute of Chartered Accountants in England and Wales (ICAEW). The ICAEW consists of more than 150,000 members and acts as an independent regulator. The role of the ICAEW is to protect the public interest by ensuring that accounting firms, members, students, and affiliates are working to the highest standards of professional conduct. 

Our Other Accountancy Offices  

Besides what’s already been mentioned above, we at Mandair & Co also provide an array of other accounting services. One such example is pension auto-enrolment schemes. Employers must now automatically enrol employees on a workplace pension scheme. We’ll get this set up, send out the necessary instructions to employees, and provide details on how to opt out.  

And that’s not all; other accounting services provided by us include: 

  • Mediation 
  • Valuation of Shares (in a Private Limited Company) 
  • Financial Advice 
  • And More!
