Ilo Basci, born in Bern, had founded a sole proprietorship at a critical time, namely in 1939. The product range: office supplies. Everything began modestly in rented premises in Soussol, with a garage as a warehouse. In 1943, the company was converted into a public limited company. The number of employees grew and the turnover curve pointed steeply upwards. The company was soon bursting at the seams, and when the weather permitted, the office desks were simply moved out into the yard. After 25 years, iba moved into its first new building in order to keep pace with developments.

"This development was less turbulent than dynamic," it was said when the first 25 years were celebrated, "and we gradually strived for only the height that was structurally appropriate for the existing foundations." Every experience gained was continuously used for further professionalization.

After the death of the company founder in 1970, his son Dr. oec. Peter Basci took over the management of the company. Since 1991, iba has been serving its customers from its modern building in Bolligen. The new building was a significant step that noticeably increased services. This was followed by the expansion of the logistics center and the introduction of fully automated media production.

In 2009, iba celebrates its 70th anniversary. In June 2010, iba is sold to the Migros Group as part of the succession plan. At the end of 2010, the previous company director Peter Basci steps down. As of January 1, 2011, the previous deputy and Head of Marketing Christa Furter takes over the management of the company.

At the end of December 2010, iba completes the Durchbruch logistics project and goes live with the new conveyor technology.
