An example of this in conversation would be someone asking "can you tell me where you company's main office is located?" and sometimes your answer can be singular or plural. "The company's main office(s) is located ......."
多くの場合本社の事を "the main office"や "the company headquarters"と言います。

Head Office is the traditional name for the company's management offices in the UK. The word 'headquarters' seems a little old fashioned these days. Headquarters was often abbreviated to 'HQ' in the past, but again, that term seems rather dated now. Companies such as security firms and taxi companies may refer to the main office as 'Control.'

Head Office is the main office of a company. It is called the 'head' office as we often use the word head in English to describe the leader or something that is at the top. For example: Headteacher, head girl, headboard, sitting at the head of the table.
Head Officeは、会社の本社のことです。
Head officeのheadは、リーダーや、何か上位、または上部にあるものを指すときに使います。
例えば、Headteacher（校長）, head girl（女子生徒会長）, headboard（ベッドの頭を置く側についている飾り板）などです。
「本社」は英語で「head office」か「main office」に当たっています。「head」と「main」は大体一緒ですが、「main office」が本社じゃない場合はめったにないと思いますが「一番大きくてそこで色んな事務を行われている所」が「main office」と言えて「head office」の方が「社長がいるところ」という可能性はあります。
うちの本社は新宿にあります。
Our company's head office is located in Shinjuku.
ここは本社ではありません。電車に乗って終点を降りてたどり着けます。

「本社」は、
"headquarters"

と言います。
