Could you have the site live by mid-October?
Yes. A six-week build lands on Oct 14. I've attached the Standard package proposal. Want me to hold a kickoff on Tuesday at 10?
Perfect, Tuesday works.

AI client management

Built for people whose work runs on clients

Clients move your business forward, but the admin around them slows you down. Harbor handles the tasks before, during and after every project, so you have more space for the actual work.

A better way to win your projects

Set packages, hourly rates and deposits once, then reuse them on every proposal. Change a number and every open quote updates.
From a one-page landing page to a six-month retainer, pre-built templates make the first draft a two-minute job.
Nudge unopened proposals with personalized reminders, and let clients ask questions without a single back-and-forth thread.
Let visitors request a quote right from your site. Add an intake form to qualify leads before the proposal is even written.
Draft and send from the mobile app, the browser extension, or your favorite AI tool with 150+ other integrations.
Grow with proposals that scale. Add teammates, set approval rules, and manage access without switching tools.

Meet Sol, your AI assistant

Instead of drafting quotes yourself, add sol@harbor.app to the email thread. Say what you need and Sol writes the proposal from the brief.
Sol runs on your pricing, availability and scope rules, weighs the client's constraints, and checks with you before sending anything.
Questions at 11pm get answered at 11pm. Sol handles scope clarifications, reschedules and reminders while you sleep.

Can we get a proposal for a six-page site?
Drafted. Three packages, 30% deposit, launch by Oct 14. Sending now.

You're free Tuesday at 10 but it clashes with your studio block. Send the proposal anyway?
