She made work in the Neoclassical style in partnership with her brother-in-law, Peter Bateman.
Ann's first mark was registered in 1791, the year her husband died and left all his property to his wife [citation needed].
A third generation of Batemans, Ann's son, William, joined the partnership in 1800.
All of the Batemans who worked in the family business are listed in the official registers of London's Goldsmiths' Hall.
Their work is characterized by fine engraving and delicate beaded edges.
