Elizabeth Cullen, 56, of Lancaster Drive, Coningsby, denied two charges of theft from B. Eyre & Son Ltd involving a total of £60,292 when she appeared before Lincoln Crown Court last week.
The thefts are alleged to have taken place between January 2010 and May 2017.
Cullen also pleaded not guilty to acquiring criminal property involving £79,815 cash between January 2004 and May 2017.
