Full Stack Developer for Tours Booking System / Software

Hello Upwork Experts, we are looking for a developer / team of developers to create our new online booking system. What we do? We are a boat tours company based in Italy, we sell our boat tours to clients all over the World through our Wordpress website and Online Travel Agents, as well as classic means of communication. What we need? After several years using different SAAS (Checkfront, Regiondo, etc) we are looking for something tailor made to our needs. We don't need something massive but, something just like these systems. Ie. manage boats inventory, real time prices and availability, seasonal pricing schedules, set timings and other rules. Technical requirements necessary - API and web hook connection: we need this to connect to our AI Whatsapp Chatbot (on N8n) and also Tripadvisor / Viator and GYG platforms - Built in back-end dashboard / calendar - Bookings must have various statuses (ie. Deposit, Paid, Pending, Cancelled) - Connection with Stripe/ any other payment gateway. - Built in email notifications (or possibility to connect them through Zapier / N8n) - Widgets / similar that can be put on our Wordpress website for online purchases. Time frame This is a medium/ long term project. Beyond the scope of this project we are looking for a Developer than can assist as we implement this system in our daily operations.
