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.

Wave

  • Automatic bank transaction import and receipt scanning require the Pro plan at $19 a month
  • The free plan pays a $0.60 per transaction fee on card payments on top of 2.9%, which Pro waives only for the first 10 transactions a month
  • Beyond 10 transactions a month the Pro plan pays the same per transaction fee as the free one
  • Amex is charged at 3.4% rather than 2.9% on both plans

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A proposal that has not been archived.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.

Wave: Can I try Wave before committing to a paid plan?

Sign up for the Starter Plan to take the bookkeeping and invoicing basics for a spin. Then, whenever you're ready, upgrade to the Pro Plan to unlock even more money management features.

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.

Wave: What happens if I want to cancel my subscription?

Yes, you can unsubscribe at any time. The cancellation of your subscription will take effect at the end of the billing period in which you cancel.

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.

Wave: Can I upgrade or downgrade my plan easily?

To upgrade to the Pro Plan, sign into Wave. Visit your dashboard or use your invoicing or accounting features, and click the 'Upgrade now' button.

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.
