Plan Harmony is an all-in-one travel agency platform built for independent advisors and boutique agencies who want to operate like a larger team without stitching together five to seven separate tools.

It replaces the typical advisor stack (generic CRM, invoicing app, payment links, commission spreadsheets, DocuSign, Asana, Squarespace, Canva) with a single travel-native product designed around the trip-planning workflow.

What's included

  • Travel-specific CRM with client preferences, documents, trip history, and bulk CSV import
  • Invoicing and online payments via Stripe Connect, with no per-invoice fees and direct payouts to your bank
  • Commission tracking with partial-payment recording, overdue detection, multi-currency support, and CSV export
  • Custom forms and e-signatures with ESIGN/eIDAS-grade audit trails (signer, IP, timestamp, content hash)
  • Task management with pre-built advisor workflow templates, push and email reminders, and a daily digest
  • White-label custom domains with native blog publishing, lead capture, and SEO-friendly sitemaps
  • Agency dashboard showing active trips, revenue, commissions, team workload, and open inquiries
  • Team management with role-based access, lead planner assignments, and clean offboarding
  • Social media template generator for branded Instagram, Facebook, and LinkedIn graphics
  • 6,000+ tours and experiences across 136 countries built into the itinerary builder

Why advisors choose Plan Harmony

Plan Harmony is the only travel platform that publishes a blog directly on the advisor's own domain, and one of the few that closes the books on commissions instead of just filing reports. It is purpose-built for travel, unlike HoneyBook or Dubsado, and modern, unlike ClientBase.

A separate consumer product helps friends and families collaboratively plan group trips with shared itineraries, voting, and expense splitting.

Questions & Answers

As answered by people managing Diff Checker and Plan Harmony.

What makes your product unique?

Plan Harmony's answer:

Plan Harmony is the only travel-specific platform that bundles a CRM, invoicing, online payments, supplier-commission tracking, e-signatures with audit trails, task workflows, custom forms, lead capture, and a native blog on the agency's own custom domain into a single product. Two capabilities are essentially uncontested in the category: publishing a blog directly under the advisor's own brand and domain, and commission reconciliation with partial-payment recording, overdue detection, and CSV export of the difference between filing a commission report and actually closing the books each month. It also ships with 6,000+ tours and experiences across 136 countries built into the itinerary builder.

Why should a person choose your product over its competitors?

Plan Harmony's answer:

It replaces 5โ€“7 separate tools (CRM + invoicing + Stripe payments + commissions + e-sig + task management + website/blog + social templates) with one travel-built platform โ€” without per-invoice payment fees and without a separate DocuSign or Squarespace bill. Versus TravelJoy and Travefy, it offers deeper commission reconciliation, true multi-currency invoicing, ESIGN/eIDAS-grade e-signature audit trails (signer, IP, timestamp, content hash), and blog publishing on the advisor's own domain, none of which the incumbents match. Versus ClientBase/Sabre, it's a modern UI, not a GDS-tied legacy system. Versus HoneyBook/Dubsado, it's purpose-built for travel, with trip-linked invoices and supplier commissions instead of generic project records.

How would you describe the primary audience of your product?

Plan Harmony's answer:

Two audiences: The professional product serves independent travel advisors and boutique agencies (1โ€“35 advisors, $100Kโ€“$10M+ in annual travel sales) โ€” including host- or franchise-affiliated advisors (Cruise Planners, SmartFlyer, Embark Beyond, Gifted Travel Network) who need an operational layer around their host's booking system, as well as niche specialists in adventure, destination weddings, group travel, and luxury leisure. The consumer product serves friends and families collaboratively planning group trips with shared itineraries, voting, and expense splitting.

  • Katakana issue?
    Another interesting point: I copied both my answer and the suggested answer into diffchecker.com, and it said they were the same. Source: almost 3 years ago
  • 16.0.3 Prod Keys finally dumped
    Never knew diffchecker.com was a thing. Thank you so much for making me aware of it <3. Source: about 3 years ago
  • How to convince someone lossless compression is possible?
    In what way did you show the file comparison? Did you use a diff like diffchecker.com ? If someone can see for themselves that every bit of data between two files is exactly the same, and still thinks they are different, IDK how you could get past that. x == x is pretty fundamental. Source: over 3 years ago
  • Advanced Diff Checker?
    How do I find the actual difference between two strings that appear equal to the naked eye? I used multiple tools and some show no differences, but some show differences. I got diffs on diffchecker.com, but it just shows me that they are different, but not how they differ. Is there a better tool for this? Source: over 3 years ago
  • Is there a library that allows to easily do diffchecks between two json?
    I am wondering if there's something that allows you to easily display differences between two json like on diffchecker.com. Is there a library that allows you to easily do that? Source: almost 4 years ago

  • Show HN: Plan Harmony โ€“ AI-powered travel planning with real itinerary structure
    Hi HN, I built Plan Harmony, a travel planning tool that helps people go from scattered ideas to a structured itinerary without the usual mess of spreadsheets, notes, and 27 open browser tabs. The core idea: most trip planners either overwhelm you with generic lists (โ€œTop 10 things in Romeโ€) or dump everything into a map/calendar with no real structure. I wanted something in between โ€”something that helps you... - Source: Hacker News / about 1 year ago
