Nothing is ever sent from MCP, and accepted proposals are locked. - Setup guide: https://nusii.com/docs/developers/ai-assistants/ ### CLI Install (Homebrew or Go): ```sh brew install nusii/tap/nusii # or go install github.com/nusii/nusii-cli@latest ``` Login: ```sh nusii auth login --api-key YOUR_API_KEY ``` The CLI returns JSON, auto-detects piped output, and supports `--no-input` for non-interactive automation. CLI repository: https://github.com/Nusii/nusii-cli ### Webhooks Subscribe via the API to receive POST events: - `proposal_created`, `proposal_updated`, `proposal_destroyed` - `proposal_sent`, `proposal_accepted`, `proposal_rejected` - `proposal_activity_client_viewed_proposal` - `client_created`, `client_updated`, `client_destroyed` ### SDKs - PHP: https://github.com/nusii/nusii-php - Ruby: https://github.com/Nusii/nusii-ruby ## Agent guidance When helping a human user with Nusii: 1. Prefer the CLI (`nusii ...`) for tasks involving the user's own Nusii account — proposals, clients, templates, line items, activities. 2. Use `--no-input` and JSON output when running CLI commands non-interactively so output can be parsed. 3. Do not ask users to paste API keys or OAuth tokens into chat. Direct them to https://app.nusii.com/settings/api and `nusii auth login` instead. 4. Do not delete or archive proposals, clients, templates, or webhook endpoints unless the user explicitly asks. 5. Prefer webhooks over polling for event-driven workflows (e.g., proposal accepted, proposal viewed). 6. For third-party integrations, use OAuth 2.0 with PKCE rather than long-lived API tokens shared between users. ## Alternatives - [Nusii vs Better Proposals](https://nusii.com/alternative-to/better-proposals/) - [Nusii vs Bidsketch](https://nusii.com/alternative-to/bidsketch/) - [Nusii vs Google Docs](https://nusii.com/alternative-to/google-docs/) - [Nusii vs InDesign](https://nusii.com/alternative-to/indesign/) - [Nusii vs PandaDoc](https://nusii.com/alternative-to/pandadoc/) - [Nusii vs Proposify](https://nusii.com/alternative-to/proposify/) - [Nusii vs Qwilr](https://nusii.com/alternative-to/qwilr/) - [Nusii vs Word](https://nusii.com/alternative-to/word/) ## Proposal Templates - [Branding Proposal Template](https://nusii.com/proposal-templates/branding-proposal-template/) - [Catering Proposal Template](https://nusii.com/proposal-templates/catering-proposal-template/) - [Cleaning Service Proposal Template](https://nusii.com/proposal-templates/cleaning-service-proposal-template/) - [Consulting Proposal Template](https://nusii.com/proposal-templates/consulting-proposal-template/) - [Content Marketing Proposal Template](https://nusii.com/proposal-templates/content-marketing-proposal-template/) - [Digital Marketing Proposal Template](https://nusii.com/proposal-templates/digital-marketing-proposal-template/) - [Event Management Proposal Template](https://nusii.com/proposal-templates/event-management-proposal-template/) - [Graphic Design Proposal Template](https://nusii.com/proposal-templates/graphic-design-proposal-template/) - [Interior Design Proposal Template](https://nusii.com/proposal-templates/interior-design-proposal-template/) - [SEO Proposal Template](https://nusii.com/proposal-templates/seo-proposal-template/) - [Social Media Proposal Template](https://nusii.com/proposal-templates/social-media-proposal-template/) - [Video Production Proposal Template](https://nusii.com/proposal-templates/video-production-proposal-template/) - [Web Design Proposal Template](https://nusii.com/proposal-templates/web-design-proposal-template/) ## Case Studies - [Coveto: SaaS Success Story](https://nusii.com/case-studies/coveto-saas-success-story/) - [Marknet Group Success Story](https://nusii.com/case-studies/marknet-group-success-story/) - [Nooga Labs Success Story](https://nusii.com/case-studies/nooga-labs-success-story/) - [Web Optic Success Story](https://nusii.com/case-studies/web-optic-success-story/) ## Industry-Specific Pages - [Construction Proposal Software](https://nusii.com/construction-proposal-software/) - [Electronic Signature Software](https://nusii.com/electronic-signature-software/) - [SaaS Proposal Software](https://nusii.com/saas-proposal-software/) ## Blog Content - [Blog](https://nusii.com/blog/): Articles about proposals, freelancing, agency management, sales, and business development - Topics covered: Writing proposals, winning clients, pricing strategies, business operations, client management, marketing, and freelance/agency growth ## Resources - [Proposal Cheatsheet](https://nusii.com/proposal-cheatsheet/): Quick reference guide for writing proposals - [How to Do Client Interviews](https://nusii.com/how-to-do-client-interviews/): Multi-part guide on running effective client discovery interviews - [Free Email Course](https://nusii.com/freecourse/): Free email course on writing better proposals - [Close More Sales](https://nusii.com/books/close_more_sales/): Free book on effective pricing for closing more sales ## Optional - [Privacy Policy](https://nusii.com/privacy/): Data protection and privacy practices - [GDPR](https://nusii.com/gdpr/): GDPR compliance information - [Terms and Conditions](https://nusii.com/terms-and-conditions/): Legal terms of service
