After warning on revenue earlier this month, struggling business-to-business software firm

Commerce One

(CMRC)

said Tuesday it will cut its staff by 30% amid a more than 80% decline in first-quarter revenue.

The firm said it will eliminate its head count by about 30% to a total of approximately 1,100. The cuts are the third round made by the Pleasanton, Calif.-based company since the beginning of last year.

Commerce One said it lost $220.6 million, or 77 cents a share, in the first quarter, compared to a loss of $228.5 million, or $1.02 a share, a year ago. The company reported revenue of $31.8 million, an 81.3% decline from the same period a year ago. Commerce One said software license revenue totaled $8.4 million, compared to $69.4 million a year ago.

However, the software sales generated directly by Commerce One were actually lower than reported because as much as $6.9 million came as a royalty payment from

, which the German software giant paid Commerce One in exchange for the unlimited right to resell jointly developed products and to resell other Commerce One technology. In the first three quarters of 2002, SAP will pay Commerce One $20.7 million, Commerce One disclosed in a recent SEC filing. SAP owns approximately 20% of Commerce One stock.

On a pro forma basis, Commerce One lost 19 cents a share, compared to a loss of 11 cents a share last year.

The current consensus estimate, lowered after the company's warning April 2, was for Commerce One to report a pro forma loss of 20 cents a share on $30 million in revenue, according to Thomson Financial/First Call. At the beginning of the month, the company warned revenue would come in at $29 million to $32 million, including software licenses totaling $8 million. The company didn't give an estimate for earnings.

During regular trading, Commerce One shares finished up 13 cents, or 10.2%, at $1.40. In after-hours trading, the stock rose to $1.44.
