The short version

  • Each has a real cost: 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.; Really Simple Systems the vendor's own pricing page as captured by the Internet Archive on 22 October 2019 listed four CRM tiers billed annually: Free at $0 for up to 2 users, Starter at $14 per user per month, Professional at $30 per user per month, and Enterprise at $46 per user per month (each roughly 7 to 10 percent higher if billed monthly); the Marketing add-on was $22 per month for up to 5,000 emails and Advanced Marketing scaled to 50,000 emails per month, though this capture is over five years old

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.

Really Simple Systems

  • The vendor's own pricing page as captured by the Internet Archive on 22 October 2019 listed four CRM tiers billed annually: Free at $0 for up to 2 users, Starter at $14 per user per month, Professional at $30 per user per month, and Enterprise at $46 per user per month (each roughly 7 to 10 percent higher if billed monthly); the Marketing add-on was $22 per month for up to 5,000 emails and Advanced Marketing scaled to 50,000 emails per month, though this capture is over five years old

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.

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.

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.

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.
