Booking platforms built as products
Booking website development, built by engineers
Booking website development, built as a product: reservation engines, class schedules, payments and partner portals engineered as one system you own, not a stack of plugins glued together and hoped for.
What a booking platform needs
Car rental, tours and vacation rentals
Many vendors,
one system
100+franchise offices and 4,000+ properties on one Casago site
Each vendor has its own system, rules and behaviour. We connect them by API into one booking engine, so availability, prices and bookings stay in step.
Payments, cancellations
and refunds
4payment providers: Stripe, PayPal, Authorize.net, Klarna
Payments, cancellations and refunds handled by the system, not by a person matching emails to bank statements.
Portals for vendors
and partners
589tour vendors run their own tours on Strawberry Tours
Vendors and partners manage their own schedules, prices and bookings in a portal of their own, so the owner stops editing on their behalf.
We had a fantastic experience working with [7Fridays]. [They] proved to be incredibly reliable and a brilliant problem-solver, tackled every challenge with a proactive approach and ensured our project was completed to perfection.
Booking platforms we have built
Strawberry Tours
A tour booking platform with a portal where guides run their tours and their business, while travellers book free walking tours in cities around the world.
This is Madeira Island
A car rental marketplace for Madeira: 9 rental companies connected by API in one booking system, with payments, cancellations and refunds handled automatically.
Casago
A property management platform for a vacation rental franchise: 100+ franchise offices and 4,000+ properties in one system for guests, homeowners and partners.Very reliable and successful work, would absolutely recommend for anyone looking for [website] development.
Your booking platform in a chat
Your AI agent, with the tools you already use
We connect your booking platform to your own AI agent, such as Claude or ChatGPT, through an MCP connection. It works inside the systems you already run, with the permissions you set: reading is open from the first day, and anything that changes data can wait for your OK.
Bookings and payments
Ask: “Show tomorrow’s pick-ups that still have no payment.” The agent reads the answer straight from your booking system, across every vendor.
Instead of
Filtering the admin by date, status and vendor by hand.
Emails to customers
Ask: “Email everyone whose Saturday tour was cancelled and offer the Sunday slot.” The agent drafts it in your own template and sends it once you approve.
Instead of
Writing and sending each email yourself.
Analytics across vendors
Ask: “Which vendors had the most cancellations this month?” Numbers from every vendor come back in one answer.
Instead of
Exporting a CSV from each system and merging them in a spreadsheet.
Booking website development
Questions, answered from our projects
How much does booking website development cost?
The deciding factor is not how many cars, tours or homes you list. It is how many sources and vendors the platform connects. Each vendor has its own system, logic and behaviour, and all of them have to work smoothly as one system on your website. One source is a fairly simple build; many vendors are where the real work is. We estimate after we have seen your vendors and their systems.
How long does booking website development take?
It follows the same rule as the cost: the more vendors and systems to connect, the longer it takes. The Madeira car rental marketplace, with 9 rental companies connected by API, took about five months, from February to July 2025: around 700 hours of work by two of our developers. Strawberry Tours started in 2022 and went live in spring 2023. With today's AI models in our workflow, we would build projects like these in roughly half the time.
Which booking platforms do you build?
Car rental, tours and vacation rentals. Our live examples: a car rental marketplace in Madeira with 9 rental companies connected by API, Strawberry Tours with 589 tour vendors in 583 cities, and Casago, a vacation rental franchise with 100+ offices and 4,000+ properties.
WordPress or custom: what do you build booking platforms on?
Whatever fits the project. The Madeira marketplace runs on custom WordPress. Casago runs on Next.js with Sanity. Strawberry Tours uses Next.js for the front end, NestJS for the business logic, and WordPress for the marketing and content team. We choose by the vendors, the traffic and who will edit the site.
Can you take over our existing booking system?
Yes. We start by researching how it works today: its code, its vendors and connections, and the parts that break. Then we maintain it and develop it further, or rebuild the parts that hold the business back.
Do you support the platform after launch?
Yes, usually. If the platform keeps evolving, with plenty of tasks and new features every month, we agree a minimum monthly capacity and work by the hour. If it is stable and new feature requests come only from time to time, we agree a fixed monthly support fee and price each new feature separately.
Which payment providers can you connect?
Stripe, PayPal, Authorize.net and Klarna, with payments, cancellations and refunds handled by the system itself. Stripe runs on Strawberry Tours, the Madeira marketplace and HR University; PayPal on Play Last Man.
Which booking software can you connect?
Any system with an API. On our live projects: Bókun and Civitatis for tours on Strawberry Tours, and VikRentCar, HQ Rentals, Renteon and Rentsyst for car rental in Madeira. We connect each vendor by its API and map its rules and behaviour into one booking engine, so your customers see one consistent offer and your team works in one place.
Can our team run the platform with AI?
Yes. We can add an MCP connection, so booking emails go out from one system and your team gets analytics by asking its own AI agent, such as Claude or ChatGPT, in plain words.
Booking website development that runs a business
Engines, portals and payments in one system
A booking website is more than a calendar on a page. Behind it sit availability from several suppliers, payments, cancellations and refunds, partner portals and the everyday communication between you, your vendors and your customers. We build all of it as one system you own.
For the Madeira car rental marketplace we connected 9 rental companies by API, with payments, cancellations and refunds handled automatically. For Strawberry Tours we built the portal where 589 tour vendors in 583 cities run their own tours, behind 160,000+ bookings and 27,389 messages between users sent through the platform itself. For Casago, 100+ franchise offices and 4,000+ properties share one site for guests, owners and partners.
