The short version

Each has a real cost: Cone the product is shaped around accountancy engagements, so a freelancer or agency outside professional services pays for engagement letter and compliance features they will never open.; 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.
They diverge on capability: Cone covers Engagement letters, Nusii covers Reusable content sections.

Where each one falls short

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

Cone

The product is shaped around accountancy engagements, so a freelancer or agency outside professional services pays for engagement letter and compliance features they will never open.
Recurring collection depends on which payment rails are supported in your country, and direct debit coverage varies enough that the headline benefit may not apply to your client base.
Practice management integration is shallower than the incumbents, so client records often exist in two systems and have to be reconciled.
Pricing is not published, which makes it hard to compare against a general proposal tool without entering a sales process first.
As a younger vendor in a market that consolidates through acquisition, roadmap continuity carries more risk than choosing an established practice software supplier.

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.

Answered from the vendors’ own pages

Cone: Is this only for accountants?

It is designed for accounting and bookkeeping firms. Other professional services firms use it, but general freelancers will find most of it irrelevant.

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.

Cone: Does it handle recurring fees?

Yes, and that is the main reason firms adopt it. Acceptance creates the fee schedule and the collection mandate together.

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.

Cone: How are payments collected?

Through supported card and direct debit providers, whose processing fees apply on top of the subscription.

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.

Cone: What is scope creep flagging?

It compares work performed against the scope agreed in the proposal and surfaces the difference so it can be billed rather than absorbed.

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.

Cone: Is pricing published?

Not in a form that can be quoted reliably. Expect a sales conversation before you can compare it on cost.
