Dropbox lets you store your files online, sync them to all your devices, and share them easily. Get started for free, then upgrade for more space and security features.
Keep rejected proposals visible to their assigned owners.
Your proposal owners get the rejection reason and a link in private chat, so they know what to revise before resubmitting.
Give quote approvers the current scope and any differences.
Your quote approver can review the latest client scope beside the proposed terms, with differences called out before they decide.
Keep proposal approval packets complete with current folder files.
Your approvers get the proposal and its supporting files together, without hunting through a shared folder for pricing or scope notes.
