Offer arrived, can I still ask for more? - first time posting

I received an offer as a janitorial supervisor and I think the pay is a little low. I am in Charlotte, in case local advice matters. The benefits are decent. Did it backfire?

I thanked them and said I was excited but hoped we could talk about the pay. They came back with a bit more.

Ask about the range, not a number on its own. It felt more collaborative.
