Zweig Group recently released the 2017 Financial Performance Survey of Architecture, Engineering, Planning and Environmental Consulting Firms. This annual publication is based on a survey of industry firms, and is compiled with analysis from Zweig Group’s team of industry experts.

The survey found net service revenue per employee (NSR/FTE) reached a 10-year high this year, with the efficiency of firms’ labor continuing to outpace average inflation rates in the U.S. NSR/FTE climbed from $137,113 last year to $141,891 in the most recent survey.

Over the past five years, NSR/FTE growth averaged near 12 percent, five points above U.S. average inflation of 7 percent for that time frame.

Since 2013, pre-tax, pre-bonus profit as a percentage of gross revenue has risen each year. This year, profits grew from 9.9 to 11.6 percent of gross revenue. As a percent of net service revenue (NSR), profit rose from 12.7 to 14.6 percent.

A measure of profitability, the breakeven multiplier, shows the dollar amount a firm must generate through direct labor to cover all labor and overhead costs. The overall median was 2.54, meaning a typical firm needs to generate $2.54 for every $1.00 spent on direct labor. As expected, high-profit firms led the way with a breakeven multiplier of 2.45 and low-profit firms lagged the sample with a breakeven multiplier of 2.91.

The last few years, lower interest rates across the U.S. have provided opportunities for firms to take advantage of low-cost capital. Debt to equity values moved up to 1.04 this year from 0.80 last year. Researchers were pleased to see that the average collection period for accounts receivable came back to earth from last year’s nearly 3-month collection period, down to around 75 days.

Backlogs continue to increase year-over-year with an average of 7.2 months. Firms working predominantly in the public sector reported higher backlogs (8.2 months), compared to predominantly private sector firms (6.1 months). Public sector firms also grew staff at a higher rate than private sector firms, adding 11 percent to their headcount where private sector firms grew by less than 7 percent.
