The Delhi-India based company takes the paper's QuarkXPress editorial pages as it goes to press and uploads the content into website templates. This has enabled the paper to upload news content far quicker.
CityAM editor Allister Heath said: "If we had to employ a separate night production team just to upload text, it would be taking resources away from the journalism."
Robert Berkeley, chief executive at Express KCS, added: "We really understand how critical deadlines are for such a commercial audience and we are delighted to help them ensure their content reaches that audience."
Express KCS has also expanded its relationship with existing client Leatham's Foods after the fine foods specialist decided to revamp branding, design and packaging across its food ranges.
The companies are in discussions about expanding their work in developing web microsites for individual product ranges.
Both of the contract wins came as Express KCS received ISO 9001-2008 accreditation.
