It just depends, there&#x27;s no rule of thumb for it (although there are obviously wrong cases).<p>For example,you provide SaaS which is applicable to a wide audience, from personal account and tiny teams, to large companies. It&#x27;s totally fine then to have public pricing for smaller use cases but need to get in touch with sales person to get a larger plan. In this case, your needs probably don&#x27;t match typical plans (you need a lot of X, and no Y), and the amount of money is big enough to be negotiable. That&#x27;s cool, since you don&#x27;t buy these things willie nillie every few days.<p>Speaking of salesmen themselves, it varies a lot from my experience. Some will send you 10 emails during 14 days trial with live demos  and trying to arrange a call and shit I don&#x27; care about. They do nothing at all to make the sale happen, just annoy a lot. While others just ask for your needs, ask a few questions for clarifications and about potentials needs and give a quote, not trying to arrange pointless calls. I have no problem with this kind of salesmen.
