Is there a limit on the numbers of proposals I can submit per day?

You can confidently submit proposals to all the projects you're invited to without worrying about limitations. Voice123 has revised and updated its algorithms and is now much smarter and more accurate - inviting you only to projects that reflect the capabilities you listed on your profile. 

Voice123 takes into account your membership level, and the percentage of proposals 'liked' by clients to determine if and when to invite you to a project. The deadline and number of proposals requested are also considered.
