Context reveals whether a person or a company is meant. If it is about a family, it means a female child. In a business context, it means a dependent company.
Die Tochter von Herrn und Frau Meier ist Ärztin.
The daughter of Mr. and Mrs. Meier is a doctor.
The business meaning is a metaphor. The controlling company is called 'Muttergesellschaft' (parent company) or 'Mutterkonzern' (parent corporation), and the dependent company is the 'Tochter' (subsidiary).
Die Muttergesellschaft hat ihren Sitz in Frankreich, die Tochter ist in Deutschland.
The parent company is based in France; the subsidiary is in Germany.
The use of 'Tochter' (subsidiary) for a company is typical of business and financial language. This meaning is very common in newspaper articles about companies or in business reports.
Der Konzern plant, seine umsatzstärkste Tochter an die Börse zu bringen.
The corporation plans to take its highest-revenue subsidiary public.

'Kind' and 'Tochter' can both refer to a person in a family. 'Kind' is more general: it can be the son or the daughter, and it can also simply mean a young person. 'Tochter' is more specific and means a female child in relation to her parents. Learners may confuse the words because a daughter is also her parents' child. If gender or the family relationship is important, you say 'Tochter'; otherwise, 'Kind' is more neutral.
