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.

SharpSpring

  • Still operates under the SharpSpring brand name (footer copyright SharpSpring 2026) as a Constant Contact product, serving over 2000 agencies and 10000 businesses per the vendor site

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A proposal that has not been archived.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.

SharpSpring: Does SharpSpring offer different pricing for agencies versus enterprise customers?

SharpSpring explicitly tailors pricing to three customer segments: SMBs, Agencies, and Enterprise. Agencies receive month-to-month plans with flexible billing, while enterprise customers get custom plans designed to scale.

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.

SharpSpring: Are SharpSpring's agency plans billed monthly?

Yes. The site specifically mentions that agencies receive affordable month-to-month plans, indicating monthly billing flexibility rather than annual-only contracts.

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.

SharpSpring: What payment options are available for SharpSpring?

The site does not specify payment methods or models. Specific pricing details and payment options require contacting SharpSpring directly or visiting their dedicated pricing pages.

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.

SharpSpring: Is SharpSpring more affordable than competitors?

SharpSpring describes itself as offering a full feature set for a fraction of the cost of leading competitors, particularly for SMBs. However, specific pricing amounts are not disclosed on the homepage.
