Nusii cover

About Nusii

Nusii is online proposal software aimed at creative agencies and professional services firms. It replaces proposals built by hand in Word, InDesign or PDF files with branded templates that can be filled in quickly and sent from the browser.

The tool tells the sender when a client opens the proposal email and when the proposal itself is viewed, so follow-up can be timed sensibly.

What Nusii offers

  • Branded templates — add a logo and brand colours to ready-made proposal layouts.
  • Reusable content — save sections and full templates, with variables that fill in client details automatically.
  • Tracking and notifications — alerts when a proposal is opened, viewed, signed or left unopened.
  • Client choices — clients can select optional items and accept or decline online.
  • Signatures and currencies — legally binding signatures in the browser, plus multi-currency and tax handling.
  • Custom sending — proposals can go out from the sender's own email address or domain.
