Custom Booking System or Off-the-Shelf Software? A Guide for Tour, Hire and Chauffeur Businesses

For a tour operator, a vehicle hire company or a chauffeur service, the booking system is the till, the diary and the shop window at once. Most businesses start, sensibly, by renting one. The question that arrives a few seasons later is whether to keep renting, or to own a system built around the way the business actually works. This guide sets out what the leading booking platforms publish about their fees, shows what those fees add up to as you grow, and gives you a straightforward way to decide.

If you already know your business does not fit a standard product, our page on custom web application development explains how we scope and build booking systems around real operations.

What the booking platforms charge

Most booking platforms combine a monthly subscription with a percentage fee on each online booking. Here is what three widely used platforms published on 5 November 2026.

Published booking platform pricing, 5 November 2026

Platform	Monthly subscription	Fee on online bookings	Notes from the pricing page
Rezdy	$49 (Foundation), $99 (Accelerate) or $249 (Expansion)	3% per online booking	Offline or agent bookings cost $1, $0.85 or $0.70 each by plan. The fee can be absorbed or passed to guests.
Checkfront	$99	3% per online booking	Offline bookings have no fee. Pricing may vary by region and currency, and the fee can be passed to guests.
Bókun	$49 (Start), $149 (Plus) or $499 (Premium)	1.5%, 1.25% or 1% by plan	0% on offline bookings, with an option to pass the fee on. A free tier has zero fees on Viator and manual bookings.

These are good products, and for many operators they are excellent value. The point of the table is not that any of them is expensive. It is that their cost scales with your turnover, while the cost of owning software scales with what it does.

What the fees add up to as you grow

Percentage fees feel small on a single booking and large across a year. Take an illustrative chauffeur or touring business taking 100 online bookings a month at an average of £180 each. That is £18,000 a month, or £216,000 a year, of online bookings. This is an assumed workload for the arithmetic, so substitute your own figures.

Illustrative annual booking fees on £216,000 of online bookings

Fee rate	Applies to	Annual booking fees
3%	Rezdy and Checkfront online bookings	£6,480 plus the subscription
1.5%	Bókun Start plan	£3,240 plus the subscription
1%	Bókun Premium plan	£2,160 plus a $499 monthly subscription

Passing the fee to the customer removes it from your costs, but it does not remove it from the price your customer sees. For a premium brand, a booking fee added at checkout can feel at odds with the experience you are selling.

Card processing is the one cost you pay either way. Stripe, for example, lists 1.5% plus 20p for standard UK cards, with no monthly fee. A custom system still pays that, but nothing on top of it.

Where off-the-shelf software is the right answer

Renting a booking platform is usually the better choice when:

• Your products are scheduled and fixed-price. Tours with set departure times and ticket prices are exactly what these platforms are designed for.
• Online travel agencies matter. If a large share of bookings comes through marketplaces such as Viator, a platform with ready-made channel connections saves a great deal of integration work.
• You need to start this month. A platform can be live in days. A custom system takes weeks.
• Your volume is still modest. At low turnover, percentage fees are small and a subscription is cheaper than owning and maintaining software.

Where a custom system pays for itself

A bespoke booking system earns its keep when the business does not fit the shape of a product. In our experience with travel, hire and chauffeur clients, these are the signs:

• Prices are quoted, not listed. Chauffeur fares depend on distance, time, vehicle, waiting time and return legs. Hire prices depend on dates, mileage allowances and add-ons. Forcing these into ticket-style products loses accuracy and bookings.
• Payments are more than one charge. Deposits, balances, card pre-authorisations for damage or fuel, and corporate invoicing all need rules a generic checkout may not support.
• Operations come after the booking. Allocating drivers and vehicles, sending itineraries and updating customers when a flight is delayed are part of the service, not an afterthought.
• The brand matters. A booking journey that looks and reads like the rest of your website converts better for premium services than a generic widget.
• The fees have grown. When annual percentage fees approach the cost of owning a system, the long-term arithmetic changes.

Our work for 4x4 Hire Scotland and Private Concierge Scotland shows both sides of this: a hire business whose bookings depend on dates, vehicles and payment holds, and a concierge brand where every enquiry needs context before anyone can quote.

Comparing the true cost of each route

Comparing a subscription with a build fee directly is misleading, because they buy different things. A fairer way is to compare the total cost of each route over three years.

1. 01Rented platformMonthly subscription plus percentage booking fees plus card processing, for every year you use it. Integration and set-up time is low.
2. 02Custom systemBuild cost once, plus hosting, maintenance and card processing each year. No percentage fees, and the software is yours.
3. 03Compare over three yearsUse your real booking volume and growth. Include the staff time each option saves or costs, not just the invoices.

The build cost depends on scope. Using the UK median full-stack contract rate of £500 a day reported by IT Jobs Watch for the six months to 5 November 2026, a focused booking system of 40 to 80 days of effort is roughly £20,000 to £40,000 before VAT.

Our guide to custom web application costs explains how that range is built and what moves a project up or down it. Running costs are covered in website and web application maintenance costs.

The hybrid many operators choose

You do not have to choose one route for every booking. A common and sensible arrangement is:

1. Keep a platform for marketplace inventory, so tours stay listed on online travel agencies without custom integration work.
2. Build a custom booking journey for your own website, where most direct, higher-value bookings arrive, with your own pricing rules and branding.
3. Connect the two so availability stays in step and staff see every booking in one place.

That connecting work is where many projects succeed or fail. Our article on API integrations that hold businesses together explains how to build those connections so they keep working when a supplier changes something.

Questions to answer before you decide

• What share of your bookings comes direct, and what share through marketplaces?
• How are your prices set: fixed per ticket, or calculated per journey?
• What did booking fees cost you over the last twelve months?
• Which tasks do staff still do by hand after a booking arrives?
• Do you need to own your customer data and booking history outright?
