What does Nusii do?
Nusii is a web-based proposal tool built for agencies and professional service firms that send a lot of proposals. Instead of wrestling with design options or bloated templates, you can create a good-looking proposal, customize it with client details, and send it in about 15 minutes. The software handles e-signatures, tracks when clients open or download your proposal, and sends you notifications at each step. No coding, no design skills, no training required.
The standout part of Nusii is its focus on speed and simplicity. You can save reusable sections and full templates, use variables to auto-fill client names and details, and let clients select optional items from a menu. The analytics dashboard lets you filter proposals by status (sent, opened, unopened) and see your acceptance rate. Nusii also integrates with popular tools like Zapier, HubSpot, Pipedrive, Slack, and Stripe — and it offers an API and Claude integration for custom workflows. The pricing is straightforward: $49/month for the Agency plan includes three user seats, CRM integrations, and a custom proposal domain, with no per-user fees.
Agencies, consultants, and B2B sales teams will find Nusii useful for one main reason: it gets proposals out the door fast. Real-world use cases include sending personalized sales proposals, iterating on templates based on conversion data, and following up automatically when a client views a proposal. The company itself is a small, profitable business that has been around for over 14 years, and the founder still jumps on Zoom calls with customers. If you need proposal software that doesn't get in the way of closing deals, Nusii is a solid pick.
