Apostrophe question for dp's CV urgent help needed!

[LedodgyChristmasjumper]

Ok dp is updating his cv he needs to know where the apostrophe goes in customers when writing about 'customers requirement specification' is it before or after the s. We think it's S' because it's both plural and possesive but want to make sure.

and before you pedants point it out I knopw I misspelt possessive!

customers' requirement specification

plural and possessive

Brilliant. Thank you.

If he is referring to several customers then you are correct - after the s.

Yes it is several customers. Many thanks.

Yes, it's plural. But if he's being that particular, he probably already knows more than the people who will read his CV.

I would put customer anyway not customers.Its like a person spec-we dont wrote persons` spec.
