So what

For the fourth quarter, revenue climbed 32% year over year, which brought the full-year revenue up 31% to $566.3 million. 

As for profit, net income was $31.4 million, or $0.54 per share, in the fourth quarter, down from the $0.83 per share reported for the fourth quarter of 2017. The decline was due to a higher provision for income taxes in 2018. For the full year, earnings per share increased by 11% to $2.34. 

Given all the accounting changes around tax reform, Paycom's growth in cash from operations of 42% over 2017 might be a better measure of the company's profitability last year. 

One of the highlights of the quarter was an improvement in the annual client retention rate that reached 92%, up from 91% -- the first increase in six years. 

CEO Chad Richison credited the strong performance to Paycom's employee usage strategy: "We believe our impressive results are due in-part to our strategy to promote usage of Paycom software among our clients' employees. We are excited about our prospects for continuing to win new business utilizing this strategy through 2019 and beyond."
