Since its founding in 1996, Integral has produced innovative and affordable software. During its first 10 years, the company focused on custom software development—working in close consultation with clients to rapidly deliver effective, functional solutions. In 2000, Integral delivered its first bespoke workforce planning software to ABN-AMRO N.V. This was followed in 2005 by projects for workforce planning software for the KNMI (Royal Netherlands Meteorological Institute) and a prominent temporary employment agency. Since 2005, Integral has focused exclusively on its own standard workforce planning software product: Checks. In 2026, Checks was acquired by Protime. Together with Protime, we are able to accelerate our growth and further develop our planning solution into the European standard.
