Hi, we're Nusii (noo-see)
Most online proposal tools push more, more, more.
More features, more complexity, more add-ons. More ways to charge you, when all you want to do is send your proposal, get it signed, and do good work.
It's overkill. And it keeps you from closing deals.
What if instead, creating a proposal was faster and easier every time?
That's the simple question that led us to build Nusii 13 years ago. And it's why our customers rave about how simple and effective our proposal software is.
“Nusii for us is the effective, easy to use option, that has little training overhead.”
If you love us, you'll really love us
On average, customers stick with us for 4+ years.
More than 6,985 businesses have used Nusii to send, track, and analyze their proposals because:
- Your dashboard
- gives a quick overview of won, lost, and pending proposals
- Reusable templates
- mean you never have to start building from scratch
- Drag-and-drop sections
- make it a snap to customize every proposal
- Online and PDF versions
- let your clients read the way they want to
- Smart notifications
- keep you informed when your proposals are opened, viewed, and downloaded
Who prefers Nusii?
Nusii is beloved by agencies, professional service firms, and other normal, un-sexy businesses who use our proposal software to close deal after deal, year after year. Our customers include:
- Marketing agencies
- Home services and handymen
- Solo consultants
- Sales and business development teams
- SaaS founders
If you want to create a fully custom, interactive design with 1,748 different colors from scratch every time you send a proposal, then Nusii is probably not the right choice.
If you want just enough branding to look professional, plus all of the back-end features that help your sales team work more effectively — including CRM integration, proposal notifications, and follow-up reminders — then you should give Nusii a try.

About Nusii
Frequently asked questions
What is Nusii?
Nusii is online proposal software for agencies, consultants, and service businesses. You build proposals from reusable templates, send them as a link or PDF, see when clients open them, and get them signed online.
Who founded Nusii, and who owns it today?
Nusii was founded in 2013 by Michael Koper and designer Nathan Powell. Michael has been the sole owner since 2019 and still runs the company day to day.
Is Nusii still actively developed?
Yes. Over the past year we moved Nusii to faster infrastructure, added a OnePageCRM integration, released a command-line tool, and launched an MCP server so AI assistants can draft proposals for you. The founder still builds the product himself.
Is Nusii backed by investors?
No. Nusii is self-funded and profitable, with no investors pushing for growth at any cost. That independence is why we can keep the product simple and focused on what customers ask for.
How do you pronounce Nusii?
Noo-see. It's often spelled Nussi, Nussii, or Nusi, but the right spelling is Nusii: one s, two i's.
Where is Nusii based?
Nusii is run by Nusii Proposals S.L., a company registered in Madrid, Spain. Businesses all over the world use it to send their proposals.
Who will I talk to if I need help?
You'll talk to Michael, the founder, who also builds the product. Email support@nusii.com, and if you'd like a walkthrough before you start, just ask for a video call.
How much does Nusii cost?
Plans start at $29 per month, with three plans based on team size and proposal volume. Every plan starts with a 14-day trial (credit card required) and is backed by a 60-day money-back guarantee. See pricing for the details.
Does Nusii work with AI assistants like Claude and ChatGPT?
Yes. Nusii's MCP server lets AI assistants look up your proposals and draft new ones from your templates. Drafts stay in Nusii so you can review and send them yourself. Here's how to connect one.
How is Nusii different from PandaDoc, Proposify, or Qwilr?
Nusii focuses on proposals only, and keeps them simple enough that a small team can send one in minutes without training. If you want full design freedom or heavy document workflows, a bigger tool may suit you better. Compare us with PandaDoc, Proposify, and Qwilr.
If you value simplicity, you'll love Nusii
Send more proposals. Make more money. It doesn't have to be harder than that.
