I work for a three-person team, and recently we've undergone a project where we are looking for a certain type of software product. Due to the nature of the product, it's a very expensive and therefore a long-winded search and pro/con elimination process.
In this process, we'e come really close to selecting one product, so we've gotten multiple quotes and demos, etc. The salesperson for that product now calls or emails 5-6 times a day asking if we're ready to purchase. No one on my team seems to want to tell him to stop.
How can I, as a person who is lower on the ladder, and not in charge of the project, politely tell the salesperson to wait? I've been in this situation before where I was in charge and I could simply tell them to stop calling and wait for our answer, but I don't want to overstep my current position, or make my team/company look unprofessional.
