Welcome to Summ It Up Accountancy

Providing Services as Individual as You are

For every client I look at your individual needs, what you want to get from your accounts and bookkeeping and build a services and fee package around this. Whether fixed or flexible, I don’t have a standard tariff for most services, the fees are designed around your needs.
No two people are the same, and the same goes for businesses so with just a handful of clients, Summ-It Up Accountancy was started in 2009 offering a personalised bookkeeping, payroll and accountancy service for small businesses.

With on site visits in our local area of Martock, Somerset, or Zoom meetings, we can meet face to face for regular updates and make sure you keep in control of your business.

Why use Summ It Up Accountancy

I set out to offer a personalised bookkeeping and accountancy service for small businesses, and with just a handful of clients, Summ-It Up was started in 2009. 

No person is the same so I decided to apply that theory to businesses; what accounting needs one business has are not necessarily the same as its neighbour. 

So that’s what I did, and still do to this day. For every client, we look at your individual needs, what you want to get from your accounts and bookkeeping and we build our services and fees around this. Whether fixed or flexible, we don’t have a standard tariff for most of our services; the fees are designed around your needs. 

I am based in Somerton, Somerset, and I am happy to do in-person meetings in my local area or with the use of technology, we can meet face-to-face and online for regular updates.   With regular meeting days at Yeovil Innovation Centre and The Wincombe Centre, Shaftesbury, there are many ways we can meet

In a nutshell:

Professionally qualified

Offering a personalised approach

Individually tailored service to each client

Start up companies

Meet Harriet

Harriet Ilott MAAT AATQB


“Basically, I love numbers, and have always enjoyed those “Hallelujah” moments when things balance. I have worked in various large companies and whilst working full time, I studied towards the AAT qualification which I gained in 2008 and became a full member later that year. In 2009 I founded Summ-It Up, focusing on visiting clients on-site to produce that hassle-free service we all want.

As well as working in an accountancy firm, my background has covered a variety of industries including dealing with Sales Invoices for a large car transportation company, purchases for an alcohol wholesaler and then progressing to managing the project team, coordinating the reporting on all the returns and ullage, and supervising the implementation of a new software system. Helping to sort problems and backlogs is a passion of mine.”
