Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Nusii

  • The plan limit counts active proposals rather than proposals sent, so an untidy pipeline of stale open proposals will push you into a higher tier even though the actual workload has not changed.
  • There is no product catalogue, pricing logic or CPQ capability, so anything involving configurable products, volume tiers or approval rules has to be worked out elsewhere and typed in as text.
  • Direct integrations are almost non-existent and most connections go through Zapier, which means a second subscription and a fragile chain between the proposal and your CRM or accounting system.
  • Acceptance is an online agreement rather than a full electronic signature service with the identity verification and audit trail that regulated buyers and some public sector clients demand.
  • The vendor is a very small independent company, which keeps the product focused and the support personal but concentrates business continuity risk in a way procurement at a larger client may question.

Responsive

  • Growth and Enterprise pricing requires contacting sales
  • Three-component pricing model (platform fee, per-user licenses, add-ons) may make budgeting complex

Answered from the vendors’ own pages

Nusii: What counts as an active proposal?

A proposal that has not been archived. Archiving completed and lost proposals frees the slot, so the limit is about pipeline hygiene rather than volume.

Responsive: How much does Responsive cost?

Responsive's Emerging Edition starts at $10,000/year. Growth and Enterprise pricing requires contacting sales. Pricing comprises three components: annual platform fee, per-user license costs, and optional add-ons for professional services and integrations.

Source
Nusii: Is there a free plan?

No. There is a 14 day trial, then plans start at 29 USD per month, with two months free if you pay annually.

Responsive: What is included in the Emerging Edition?

The Emerging Edition at $10,000/year includes unlimited response projects, AI & automation studio, unlimited content collaboration, integrations, and admin support. It is designed for early-stage proposal teams with low-to-moderate RFP volume.

Source
Nusii: Does it handle legally binding signatures?

It records online acceptance with a timestamp. For qualified electronic signatures with identity checks you need a dedicated e-signature service.

Responsive: When do I need Growth or Enterprise editions?

Growth Edition is for organizations with weekly RFP volume and cross-functional collaboration needs. Enterprise Edition is for complex multi-team operations with dedicated proposal teams and global or multi-region requirements. Both require custom quotes.

Source
Nusii: Can several people work on the same proposal?

Yes on the Agency and Business plans, which include 3 and 5 users respectively with additional seats charged separately.
