About Us

We are Terence James Systems Limited - industry leaders for over 35 years.

Our mission has always been to understand our customers' needs and keep delivering premium software that "does what it says on the tin"!

Our dynamic team's solid business experience combined with a dogged determination to deliver, means your objectives are at the heart of everything that we do. 

Because of this, when you work with us, you really are working with us:

Everything is done in-house! We don’t outsource any of our development work.

When you talk to TJ Systems, you are talking directly to the delivery team (there’s no support barrier between developers and users).

That way, we always keep a finger on the pulse of your operations.

We can support you directly and are always refreshing and enhancing systems as your business scales and grows - taking your business to the next level! 

With zero marketing and no sales team, our customers are our biggest brand ambassadors.

All our business comes from referrals because our software speaks for itself.

We offer consultancy and project expertise based on our pooled experience.

"The support is always reactive, efficient and friendly. TJ System is a partner we can count on and that is what matters to us the most."

Cedric Allain, IT Manager

Our Story

"Occasionally we get calls for Mr Terence James; it causes a chuckle because the business was actually built by Terry Baxter and James Harrington in 1979.

We believe FMA, first live use 1980, to have been the world’s first multi-currency, distributed computing accounts package. Multinational reporting and multi-language features remain key strengths of the TJ Accounting product which we continue to refresh and enhance for the prevailing functional and technical requirements of small, medium and large organisations; a project which will continue until long after the cows come home.


Somewhere along the line our customers started asking us to develop other applications, so we diversified; if you need a business application, we like to think we are more qualified than most to produce a splendid result for you."

Terry & Jim, Founders
