Is it customary to say いらっしゃいませ in a corporate setting?

In the related question, the target is "someone", which brings me to the
conclusion that OP there means "if anyone other than people working in the
same office arrives, should いらっしゃいませ be used?".

For example, when clients of a software engineering firm you're working for
visit your office, is it customary to say いらっしゃいませ since they are customers,
or is いらっしゃいませ usually just said in a service-oriented environment (such as
restaurants, hotels, and shops)?

Context: We have a Japanese HR Officer who happened to be in the same room as
us when the clients arrived and she greeted with いらっしゃいませ, which perplexed me
a bit because I thought it was only used for restaurants and whatnot.

Yes, it is.

I think it's not wrong in your office but a little weird.

"お待ちしておりました。(Omachisiteorimasita)" may be best for this situation.  
It means like "We(I) have been waiting for you."
