Stop paying 'free' fees and learn which booking software actually protects your margins at scale.
If you’re still managing bookings via WhatsApp threads and manual spreadsheets, you’re not running a business—you’re managing a chaotic hobby that will break the moment you try to scale.
I’ve spent years building a tour portfolio in Portugal and Spain that now brings in over €2M a year. Across the last several years, we’ve cleared over €10M in aggregated revenue. I didn't get there by being the best tour guide; I got there by building systems that allow me to sleep while bookings roll in for our private Sintra tours or our Douro Valley wine experiences. The heartbeat of that system is your booking engine.
Choosing between FareHarbor, Rezdy, and Peek Pro isn't just about which interface looks prettier. It’s a mathematical and operational decision that dictates your margins and your ability to distribute through OTAs like Viator and GetYourGuide.
How much does booking software actually cost?
The biggest trap in the tours and activities industry is the word "Free." There is no such thing as free software. You either pay a fixed monthly subscription (SaaS model) or your customers pay a percentage-based "booking fee" on top of your retail price (Commission model).
FareHarbor and Peek Pro typically operate on the commission model. They tell you the software is $0/month, but they add a 1.9% to 6% fee to every checkout. Rezdy, conversely, usually offers a tiered subscription model where you pay a flat monthly fee plus a smaller per-booking fee or a flat fee for OTA connections.
Let’s look at the Total Cost of Ownership (TCO). If you are a high-volume operator in a competitive market like Lisbon, a 6% fee added to your €150 tour price is €9. If you move 20,000 passengers a year, you are effectively paying €180,000 for your "free" software.
| Annual Revenue | 6% Consumer Fee Model (FH/Peek) | Subscription Model (Rezdy - Pro Plan approx.) |
|---|
| €500,000 | €30,000 | ~$2,400 + processing fees |
| €1,000,000 | €60,000 | ~$3,600 + processing fees |
| €5,000,000 | €300,000 | ~$6,000 + processing fees |
Note: Processing fees (Stripe/Adyen) of roughly 1.5%–3% apply to both models.
At my scale, paying a percentage of every seat sold is painful. However, for a smaller operator just starting out in the Algarve or a boutique outfit in Seville, the $0 upfront cost of FareHarbor is a godsend for cash flow. You have to decide: do you want to protect your margins at scale, or do you want to eliminate fixed overhead while you grow?
Which software has the best OTA channel manager?
As you move toward that €5M or €10M aggregated revenue mark, you cannot survive on direct traffic alone. You need the "Billboard Effect" from Viator, GetYourGuide, Klook, and Expedia. A booking system is only as good as its API connection to these giants.
If your software has a "leaky" API, you will experience the nightmare of overbooking. Imagine selling out a private yacht charter in Cascais on your website, but the software fails to tell Viator fast enough, and a family of six books the same slot. Now you’re stuck with a manual cancellation, a hit to your ranking, and an angry customer.
Rezdy is widely considered the "Switzerland" of the industry. They started as a distribution engine and expanded into a booking system. Their channel manager is robust because they treat other booking systems as partners. FareHarbor, being owned by Booking Holdings (the same parent company as Booking.com and Agoda), is incredibly polished, but some operators feel their ecosystem is a "walled garden." Peek Pro has made massive strides in the US market with their "Peek Connect" distribution, but in my experience operating across Iberia, Rezdy and FareHarbor still hold the edge for European OTA reliability.
Custom websites and API flexibility for luxury operators
If you are running a high-end luxury driver service in Porto or specialized food tours in San Sebastián, your website needs to look like a premium brand, not a generic template. This is where "widgets" vs. "APIs" come into play.
Most operators use a "Buy Button" or an iframe. It’s easy to install, but it’s bad for SEO and feels clunky on mobile. As you scale, you want a headless checkout experience where the booking flow feels native to your site.
- FareHarbor: Excellent at "doing it for you." They have an internal design team that will build your site for free if you use their software. The downside? You don't truly own the code, and their lightframes can be restrictive for advanced tracking.
- Rezdy: Highly flexible API. If you have a custom WordPress or Webflow site, your developer can build a completely bespoke checkout flow. This is what we prefer for our high-end brands where the user experience must be seamless.
- Peek Pro: Offers a very modern, slick "out of the box" checkout. It’s arguably the best-looking mobile interface, which is critical since 70% of last-minute bookings in cities like Barcelona happen on a smartphone.
When managing multiple currencies—say, accepting USD from a client in New York for a tour priced in EUR in Madrid—you need to look at how these platforms handle FX. FareHarbor and Peek handle the complexity well, but be wary of the hidden "spread" on currency conversion. A 2% FX fee on top of a 6% booking fee eats your profit faster than a group of hungry tourists at a tapas bar.
How to switch booking software without breaking your business
Switching software is like performing heart surgery while running a marathon. I have seen operators lose months of data or end up with double-booked vans because they rushed the transition.
If you are moving from a legacy system or spreadsheets to one of these "Big Three," follow this checklist:
- The Data Audit: Export every single future booking into a CSV. Do not rely on the new software's "import" tool to be perfect.
- The Parallel Period: Run both systems for 48 hours. Keep your old calendar open while you configure the new one.
- The Manifest Migration: Manually verify every booking for the first 30 days post-launch. Software glitches usually happen at the "cut-off" times (e.g., preventing a booking 2 hours before the tour).
- The OTA Re-link: This is the danger zone. When you disconnect Viator from Rezdy to move to FareHarbor (or vice versa), there is a window where your availability isn't syncing. Do this at 2:00 AM on a Tuesday, not on a Friday afternoon.
- Staff Re-training: Your guides in the field in Madeira or your drivers in Seville don't care about the backend; they care about the manifest. Ensure the mobile app of your new provider is installed and tested on every staff member's phone before you go live.
Which one should you choose in 2025?
There is no "best" software, only the best software for your current stage of growth. After years of testing these tools and coaching other operators globally—from safari lodges in Kenya to walking tours in Tokyo—here is my breakdown:
Best for Solo Starters and Small Teams: FareHarbor.
The "Free" model is unbeatable when you have more time than money. Their support is legendary; they will literally help you set up your items and build a basic website. If you are doing under €200k a year, the 6% fee is a fair trade for the level of service you get.
Best for High-Volume Fleet Management and Scaling Operators: Rezdy.
If you are pushing toward that €1M to €5M+ mark, you need to own your margins. The subscription model saves you tens of thousands of euros annually once your volume hits a certain threshold. Their API and channel manager are the most reliable for complex operations involving multiple vehicles and external agents.
Best for Modern US-Based Lifestyle Brands: Peek Pro.
If your brand is heavy on Instagram aesthetics and you want the slickest mobile checkout experience possible, Peek is a strong contender. They have excellent marketing automation tools (abandoned cart emails, review requests) built-in that feel more modern than the competition.
Building a €10M aggregated business isn't about the tours; it's about the tech stack that supports them. Choose the one that lets you stop "working" in the bookings and start "operating" the business.
