Hotel Booking Engine & Payment Gateway Integration – Existing Website

I have an existing homestay website. The website is already live, and I am looking for a developer to improve the room booking process, integrate an online payment gateway, and make a few front-end adjustments. The existing website design and most of its pages are already in place. I would prefer to work with the current setup rather than rebuild the entire website. 1.⁠ ⁠Room Booking System The homepage already has a booking form with From Date, To Date, Adults, Children, Rooms, and Check Availability options. I need a developer to make this booking process functional using the existing system or a suitable ready-made booking plugin. The booking system should: •⁠ ⁠Allow guests to select check-in and check-out dates, number of guests, and room type. •⁠ ⁠Show available rooms and their rates where supported by the booking system. •⁠ ⁠Collect basic guest details during booking. •⁠ ⁠Allow the property owner to view and manage reservations. •⁠ ⁠Prevent double bookings for the same room and dates where inventory management is supported. •⁠ ⁠Send booking confirmations to guests and booking notifications to the owner. 2.⁠ ⁠Online Payment Gateway Integration Guests should be able to pay online as part of the room booking process. The requirements include: •⁠ ⁠Integrate suitable payment gateway. •⁠ ⁠Support Paypal, debit/credit cards, and other payment methods available through the selected gateway. •⁠ ⁠Connect the payment process with room reservations. •⁠ ⁠Handle successful, failed, and cancelled payment transactions correctly. •⁠ ⁠Confirm bookings only after successful payment verification when instant confirmation is enabled. I can provide the required merchant account details and configuration access. 3.⁠ ⁠Front-End HTML/CSS Improvements A few areas of the website need minor visual and usability improvements. These include: •⁠ ⁠Improve the layout of the homepage booking form. •⁠ ⁠Ensure the booking section works properly on mobile devices. •⁠ ⁠Adjust spacing, buttons, and the overall presentation where needed. •⁠ ⁠Correct noticeable alignment or navigation issues in the affected sections. •⁠ ⁠Maintain the current website design and styling as much as possible. 4.⁠ ⁠Tourist Attractions & Government Booking Links The website already includes information about nearby tourist attractions. I need the developer to review the existing external booking buttons and make sure they direct visitors to the correct official government booking or information pages. Some attractions may support online reservations, while others may provide information or require offline ticket purchases. The requirement is limited to updating the links and improving their presentation. There is no need to integrate directly with government booking systems. 5.⁠ ⁠Testing & Final Delivery Once the changes are completed, I need the developer to: •⁠ ⁠Test the complete room booking process. •⁠ ⁠Test the payment gateway in test mode and, once the required credentials are available, in live mode. •⁠ ⁠Verify booking confirmations and owner notifications. •⁠ ⁠Check the affected website sections on desktop and mobile devices. •⁠ ⁠Fix any issues introduced by the changes. •⁠ ⁠Provide a brief explanation of how to view and manage reservations. Developer Requirements I am looking for someone with practical experience in: •⁠ ⁠Modifying and maintaining existing websites. •⁠ ⁠HTML, CSS, JavaScript, PHP, or the website's existing technology. •⁠ ⁠Hotel or homestay booking systems and plugins. •⁠ ⁠Indian payment gateway integration. •⁠ ⁠Mobile-responsive website development. •⁠ ⁠Making changes to live websites without disrupting existing functionality. Project Expectations I would prefer to use suitable existing booking components or plugins wherever possible instead of developing a completely new system. The focus is on getting the booking and payment functionality working reliably while keeping the current website largely unchanged. Before applying, please review the existing website and answer the following questions: 1.⁠ ⁠Can you work with the existing website structure and booking functionality? 2.⁠ ⁠Which booking system or plugin and payment gateway would you recommend for this requirement? 3.⁠ ⁠Which parts of the listed scope can you complete, and are there any technical limitations or dependencies? 4.⁠ ⁠Have you worked on similar hotel booking systems or online payment integrations? Please briefly describe your experience. I can share website access and additional technical details with the selected developer.
