When using pronouns, make sure you maintain the same or matching pronoun throughout a sentence and paragraph.
I recently read
The writer swaps from being part of the company (by using ‘us’) to being external to the company (by using ‘their’). Which is jarring and somewhat confusing.
If in doubt about which pronoun to use, swap in the correct noun and make sure the sentence makes sense.
Or make a conscious choice about the type of pronoun (such as if your business uses me or we, us or it), put it into your style guide and stick to it.
