I'm not sure if this question is appropriate for Sales Stack Exchange, so here's a preview before I attempt to post it.
My client doesn't have the budget for Salesforce Communities. They need to allow their vendors to login, update their address info, status, and skill sets. Communities will obviously allow for this, but not cost effective for them. I noticed there is still Salesforce Sites, but I need to allow user logins. Say they need 1,000 users to be able to login and update their information and status, is Sites a less expensive option?
I want to avoid writing a .Net application and going through the API, or similar approach.
Is this question appropriate?
