Font license, do I pay for font or my collaborators' license covers it?

My company is collaborating with another company on a project. They have a full licence for a font family, but we are building a webpage for this project. does their licence cover this project or do we need our own?

Here is my site Read-Only: LINK

Read the licence of their font and you’ll get that infos. Typefaces can have an permissive and unlimited licence, but they can also be limited per project, and they’re often limited per volume of audience too.
