I have a question about the lien process. If a supplier sells to a contractor and the contractor picks up the materials

I have a question about the lien process. If a supplier sells to a contractor and the contractor picks up the materials and takes it to the job site (and the contractor does not pay for them) does the supplier have lien rights? Even though they did not furnish/deliver the materials directly to the job site and the contractor did a “willcall”
