The first ever version of Systematics was developed for Apple II and was released in the European market.

When the use of Personal Computers gained momentum, the product was re-written for MS-DOS based IBM compatible PCs and was promoted as Systematics I and II. Systematics was rated as one of the top 5 accounting products in Europe. Some 37,000 modules of Systematics were sold to around 11,000 users.

The product was re-labelled as AccountsMaster (consisting of GL/SL/PL) and PayMaster (only Payroll) and 60,000 suites were delivered across UK/Europe packaged with the then popular Amstrad PCs making it the most widely distributed product in the market.

The next generation of Systematics DOS version by name Systematics Accord was launched.

Several thousand licences of Systematics Accord were sold between 1993 and 2000 and continues to be in use by thousands of businesses in UK and several other countries even today.

The product's IPR was acquired by MAARS with the objective of injecting new life in to Systematics with a new Windows version.

MAARS completed the development & testing of the Payroll module and released it in the market. MAARS also completed the Windows upgrade for the finance ledgers, stock control & invoicing modules and successfully had the accounting modules accredited by ICEAW.

We, Earth Solutions (UK) Limited acquired the ownership of the product. The new management quickly completed the development of additional modules

Flexible Accounting Ltd purcahsed all the assets of Earth Solutions Ltd and have developed the software as the current flexiaccounts and flexipayroll software.
