Sole practitioner design firms reported a strong September IDBI score of 53.6, indicating ongoing strength. Firms of larger than 25 or fewer than 10 employees also reported growth in month over month billings. Firms employing between 10 and 24 workers however, reported declining billings for the quarter.
Only design firms in the Midwest showed billing increases relative to second quarter scores. Other regions report a softening if not an outright decline in billings. Scores ranged from 62 in the South (still positive month over month) to 42 in the West. The IDBI score for design firms in the West indicates declining month over month billings for the region.
