IRIS Enterprise Software, formerly Exchequer Software, was established in 1984 when the PC was just starting to find its way into small and medium sized businesses (SMEs).

Exchequer Software's origins were in the development of specific solutions for a wide variety of different industries, culminating in a suite of financial modules launched onto the market in 1990.

Exchequer Software's focus was on the SME sector of the market, and the company continued to develop industry specific solutions for this sector of the business community. This focus, and the ensuing 20 years experience, gave Exchequer Software the relevant knowledge and understanding to deliver award-winning solutions to SME customers worldwide.

Now over 10,000 organisations utilise Exchequer to manage their accounts and run their business operations.

The experience gained over the years, combined with the company's continued commitment to providing leading edge, innovative, reliable and customer-focused accounting and business solutions, has achieved positioning as one of the most reputable and successful suppliers of accounting systems in the mid-range market.

In March 2005, Exchequer Software was acquired by the IRIS Group - a leading provider of accountancy and business software to accountants, practices and small businesses in the UK - and became known as IRIS Enterprise Software.
