Where it falls short

Gaps we found in research, each linked to its source.

• Plans cap active proposals: 5 on Freelancer ($29/mo) and 20 on Agency ($49/mo); Business ($129/mo) lists 50+. nusii.com, 2026-10
• Multiple signatures and team permissions are only on the Business plan ($129/mo), where versioning history is still listed as coming soon. nusii.com, 2026-10
• Native CRM integrations cover HubSpot, Pipedrive, Less Annoying CRM, OnePageCRM and Highrise; other CRMs such as Salesforce have to go through Zapier, Make or the API. nusii.com, 2026-10
• Several Capterra reviews (2016 to 2019) ask for more design options, more template designs and a richer text editor. capterra.com, 2026-10

Who should pick Nusii, and who should skip it

Pick it if you fit this profile: creative and professional-services agencies sending client proposals, often across languages and currencies. Where it earns its place: Genuinely simple, with published pricing and a 60-day money-back guarantee.

Look elsewhere if this limitation is a deal-breaker: Active proposals are capped at 5 on Freelancer and 20 on Agency. Also look around if rfps is central to how you work (0/3 here). In that case, one of the Nusii alternatives may fit better.

Bottom line

Best use case in one line: Agencies and consultants who want simple, multilingual proposals at a clear price.
