Get up to date

Many clients have a need for a “catch-up” project to get their books and accounts up to date. We will agree with you a plan to complete the project at the outset and agree a fixed price. Interest free credit is available for these projects – please ask for further details.

Easy Switch to Lilley & Co

With our easy switch service we will contact your outgoing accountant and do all that’s necessary for a seamless transition. As a client you don’t need to do anything but continue to run your business whilst we sort out the details.


We make the most of technology and use either Quick books online or Xero accounting packages to maximise efficiency. We can also show you how to process your receipts and invoices easily with the use of a smart phone. Imagine that? No more disorganised bags of receipts and invoices to worry about.

A Payroll Client

I just wanted to say that it has been a pleasure to work with you and that I finally feel that we are getting to a much better place accounts wise. This has been a source of great stress for me for months as I was struggling to find the right people on top of my capabilities in this department being limited. I feel the work you have done to date has been very very good.

You have helped us make a huge amount of progress, you ask all the right questions, look into everything for which I am hugely grateful.
