Proposal Generator

A complete weekend playbook to launch this AI business, built end-to-end with Lovable.

6 min read Idea #210
TL;DR

Pulls from a template library and formats custom proposals in minutes. Editable templates, variable fields, and PDF export.

Who buys this

Freelancers, agencies and consultants who rewrite the same proposal from scratch for every new lead.

Where to start in Lovable

Paste this into Lovable as the opening prompt. It sets up one screen and one job, which is easier to grow from.

Build a proposal generator. User saves reusable blocks: services, pricing, case studies and terms. For a new proposal they pick blocks, fill in the client name and scope, and get a clean branded proposal at a shareable link. The client can accept online, which timestamps it and notifies the sender. Add a dashboard of sent, viewed and accepted proposals, and a template so the next one is even faster.

What you will need to wire up

  • Lovable AI Gateway
  • Lovable Cloud (Postgres)
  • Resend
  • Stripe

Build order

  1. Reusable blocks kill the blank page. The whole value is never writing your services and terms twice. Nail the block library and a new proposal is minutes of assembly, not an hour of writing.
  2. Accept online with a timestamp. A client clicking Accept beats a vague 'sounds good' email. That recorded acceptance is what turns a proposal into a deal you can act on.
  3. Know when they opened it. Seeing that a proposal was viewed but not accepted tells the sender exactly when to follow up. That timing insight closes more deals.

Where this usually breaks

  • Legally binding e-signatures are a regulated space. If clients need real signatures, integrate a proper e-sign provider rather than claiming legal weight you cannot back.
  • The market has big players (PandaDoc, Proposify). Win on speed and simplicity for solo users, not on matching enterprise feature lists.

How it makes money

  • Free up to a few proposals, then monthly. Users start free and pay once proposals are winning them work, which is when they can afford it.
  • Higher tier for branding and analytics. Custom branding and view tracking are the natural premium features agencies pay for.

Why this idea works right now

AI has dropped the cost of building software to almost zero, but most people still think you need a team of engineers to ship a real product. You don't. The opportunity behind «proposal generator» is that the underlying tech is finally good enough, the audience already exists, and the tooling: specifically Lovable, lets a single person ship in days what used to take a startup six months.

The 4-step Lovable playbook

  1. Describe the product to Lovable. Open Lovable and paste a one-paragraph spec: "Proposal Generator". Lovable instantly scaffolds the UI, pages, and components. No setup, no boilerplate.
  2. Plug in the AI brain. Use Lovable AI Gateway to add the smart layer: text generation, image vision, transcription, classification, without touching API keys or backend code.
  3. Add auth, database & payments. Enable Lovable Cloud for instant user accounts, a Postgres database, and file storage. Connect Stripe in two clicks to start collecting money.
  4. Launch & monetize. Pulls from a template library and formats custom proposals in minutes. Editable templates, variable fields, and PDF export. Publish to a custom domain straight from Lovable and start sharing the link the same day.

What you'll have at the end

  • A live product on its own domain
  • User signup, login & profiles
  • Database with user data & content
  • AI-powered core feature working in production
  • Stripe checkout to accept first payments
  • Built without writing a single line of code
The hard part was never the code. It was getting started. Lovable removes that wall: describe the product, watch it appear, ship it.
