Sales workflow
Easily integrate Nusii with your sales workflow
Tie your proposals into your sales processes, where they belong. Nusii offers built-in integrations for popular workflow, chat, and CRM tools. Plus, do whatever you want with your proposal data with our API and Claude integrations.
“We use Nusii via API, command line and AI agents to go through a process from call transcripts, emails, standards, rate card and much more to build a proposal.”
Built for the whole team
Every team member is comfy using Nusii
When you're writing proposals, the goal is to get them out the door — not to make sure everyone on your team knows how to use a complicated tool.
Nusii has no learning curve and no training required. If your usual "proposal person" is out for the day, anyone can log in and make sure your deals keep closing.
“Nusii for us is the effective, easy to use option, that has little training overhead.”
Psst… Agencies pay less on Nusii
Most proposal tools lock the best stuff behind their highest-priced tier. We don't.
Get CRM integrations, custom proposal domain, and 3 user seats for just $49/mo. (Not $49 per user per month. Big difference.)

Customer story
Coveto increased their conversion rate to over 50% managing proposals with Nusii
“With Nusii, we have a lot more data and we can analyze it and see which proposals converted and which didn't convert. And because it's so easy to change the template, we can quickly create new versions, iterate on proposals, and try to find a better version.”
Speed + personalization
Find the right balance of speed + personalization
Lots of agencies are racing to generate proposals faster with AI. But faster isn't better when you're mass-blasting generic proposals that don't close sales.
Nusii is built for agencies that want the “personal pitch” at scale. Create reusable sections, remove irrelevant ones, and tweak the parts you need to. Use dynamic variables to ensure your client's name and business are correct throughout. And get notified the instant your proposals are opened and looked at.
A note from our founder
Actually personal support when you need it
Another reason pros love Nusii: we're a calm, profitable small business that's responsive to our customers' needs. We've been around for more than 14 years, and we're not going anywhere.
We regularly jump on Zoom with our customers to hear how we can serve you better. This often looks like:
- Helping new Nusii users set up your account and proposal templates
- Creating useful new features like optional pricing sections/items
- Adding CRM and workflow integrations
Hi, I'm Michael Koper. I'm the founder of Nusii, and I work with customers directly, in a refreshingly helpful way you probably haven't experienced since dial-up.
Customer story
“I hired a salesperson who wasn't very technical and she was able to use Nusii in only a few minutes without a problem.”
“What separated Nusii [from Proposable and Proposify] was usability and ease of use. I could imagine onboarding salespeople and having them learn the system the same day, not spending hours trying to figure it out.”
