  • Onyx will advise on Restructure for expansion that protects assets and maximise your tax-saving opportunities.
  • We can offer company secretarial help which will ensure all your records are kept up to date with Companies House & HMRC.
  • With Onyx you can have peace of mind that your accounts will be completed in a timely manner avoiding any late filing penalties.

VAT & Payroll* Services

  • Submit accurate VAT returns on time with our secondary review.
  • Onyx can advise on your VAT returns and ensure all HMRC VAT queries are dealt with.
  • Outsource payroll to ensure staff pay is correctly calculated, validated and delivered on time.
  • We will ensure that your RTI or Real Time Information is correct and processed to HMRC (as legally required).
  • Onyx will administrate and handle auto-enrolment and pension reporting.


* Payroll fees are based on the number of employees and calculated per pay run, this cost is in addition to the accounting fees.

Financial Management

  • Measure profit margins and losses with monthly/quarterly reporting packages.
  • Know your breakeven point, seasonal profitability and short term working capital position.
  • Our reporting will provide you with financial control to make informed operational decisions.

  • This control and up to date reporting gives you better credibility with external stakeholders when it comes to obtaining funding.

Outsourced Services

  • Avoid the hassle of not having to worry about software licences and updates.
  • A part time Finance Manager is far more cost effective than employing one internally.
  • Fully outsource bookkeeping – your admin team uploads paperwork and we process it directly onto your accounts software.

“We’ve been using Onyx for around three years now and Paresh has really helped us to take financial control over our business. Three years ago we didn’t really have a clue where we stood from one day to the next, but Paresh and his team help us to keep well informed. He’s also provided us with some really useful insight into how we could run things better from a financial point of view. I’m confident he could do the same to you.”
