The goal is to build a full-featured B2B travel portal that lets my agency sell flights, hotels, and activities under one roof while giving me the freedom to plug in new suppliers—either through standard APIs or by entering inventory manually. Flight booking is the first module that has to go live; hotel and activity booking can follow immediately after the core flight workflow is stable. The system must run smoothly on both desktop and mobile, with a clean, responsive interface that travel consultants can use from an office PC or on the go from a phone. Key outcomes I need from you • A web portal and public site with separate agent log-ins, mark-up controls, reporting, and balance management. • Integration hooks for external supplier APIs plus a back-office screen to add or modify products manually. • Year-one support and maintenance packaged into your hand-over plan (security updates, bug fixes, minor enhancements). When you reply, point me to past projects that prove you have already built or heavily customised travel or booking platforms; screenshots, live links, or short videos are welcome. A concise outline of your tech stack, estimated timeline, and any third-party services you expect to use will help me compare proposals quickly. I’ll review portfolios on a rolling basis and shortlist as soon as I see a match.
