Established in 1996 in Adelaide, South Australia, Ledger grew out of a need identified by its Director after many years working in and consulting to businesses, for an organisation to supply outsourced business administration and data entry services. It was initially established as a data processing bureau and data management remains a significant component of the firm’s services provision.

Here at Ledger we recognise the need for quality and trustworthy staff. We have assembled an experienced team of data entry processing specialists that have complementary skills and relish the challenge to go the extra distance to deliver business administration and data entry services to clients in a fast, professional and effective manner.

Karen Simmonds, Director, heads up the team. A qualified Accountant and AAT member, her extensive experience in corporate, international and business banking is backed by strong analytical skills, sound financial know-how and business consultancy expertise in the manufacturing and e-commerce sectors. A sporting enthusiast, Karen is a past state golf champion and was awarded with the Australian Sports Medal for 2000.


Management of databases usually involves several sets of skills, which are often difficult to find in a small-to-medium size business. At Ledger, we have the data processing skills to process large amounts of data.

Do you have large amounts of data to input into a database?

We specialise in processing large volumes of data for survey results, membership information, confidential records and financial records.
