Proposal.biz vs. Assembly

Proposal.biz is a proposal creation and management platform built to help businesses draft, send, and track professional proposals with ease. It streamlines the sales and business development process by offering customizable templates, real-time tracking, and e-signature capabilities, allowing teams to move deals forward faster. With Proposal.biz, users can create polished, branded proposals in minutes instead of hours, eliminate manual follow-ups by tracking when a client views a proposal, and close deals faster with built-in approval and signature workflows.

Assembly is the AI-powered platform for professional service firms, from accounting and bookkeeping practices to agencies and consultants. It combines a branded client portal, a simple CRM, and an AI app builder that lets your firm add any software it needs without a dev team. Clients get one branded place for messages, files, forms, tasks, contracts and e-signatures, and invoices they can pay online. Your team runs on a CRM with automated reminders and an AI Assistant that knows full client context. When your firm needs something the portal doesn’t do yet, describe it.
