Nusii vs Proposal Expert

Nusii has no write-up on Specifiction yet; its figures are above.

Proposal Expert is a web-based subscription service for creating proposals, combining an editor, AI feedback, and CRM integrations. Its assistant, Fred, suggests stronger wording, flags weak points, and supports multilingual proposals. Engagement tracking reports when a client opens a proposal, which sections they read, and how long they spend reading. Electronic signatures use email verification and record an audit trail. HubSpot and Pipedrive integrations are listed for Professional, while Salesforce is listed for Business. The company says customer data is stored on servers in the EU, encrypted in transit with TLS 1.2+ and at rest with AES-256, and not sold or used to train foundation models. The free plan includes three proposals per month, 25 AI credits, five templates, three e-signatures per month, basic analytics, and 250 MB of storage. Starter costs €24.00 per month. Support is available in Dutch and English, with weekday replies within one business day; there is no phone line during the beta. Monthly AI credits are pooled per workspace and roll over for one month, capped at one times the monthly allocation.
