ASID Interior Design Billings Index (IDBI) - July 2019

The ASID Interior Design Billings Index (IDBI), a key billings indicator for interior design firms and the profession, dipped in July to a score of 49.6. While an index score of 50 indicates firms saw no increase or decline in business activity, this is the fourth consecutive month of lower scores since the IDBI reached its highest score, 60.8, in over two years. Many panelists note that tariffs have increased prices and created uncertainty around the pricing of materials. The three-month moving average also slowed to a score of 51.5 in July compared to a score of 53.3 in June.
