In the mid-60s Frans Callaert was providing accounting and tax services to local entrepreneurs. His son, Luc Callaert, became certified auditor in 1988 and established an audit-accounting firm in Londerzeel.

Since 1996 this firm has grown steadily and meanwhile the team consists of three auditors, one trainee auditor, one accountant-tax consultant, four senior account managers and two assistants. Meanwhile, the third generation jointed the company and a Dutch branch was opened.
