Ways to tell them apart:
Beside means next to or at the side of something or someone.
Besides means in addition to or apart from something.
Think of beside as a spatial preposition and besides as an adverb of inclusion or exception.
You can replace beside with next to to check its correctness in a sentence.
Use besides when you mean also or moreover and check if adding information complements the sentence.
