Southampton have offered full-time contracts to their women's team after they won promotion to the Championship.
Players had been working under part-time contracts but will now go professional for next season.
"The change in status for Southampton FC Women from part-time to full-time is an exciting one," manager Marieanne Spacey-Cale told the club's website.
"We are aware of the challenge moving into the Championship will bring on the pitch, so having quality time with the squad based at Staplewood will support this transition and give us a good chance to settle into the league.
