Say you run a tour operator in Thane that sells domestic family packages and a few group departures each season. The figures below are only an illustration.
A couple with two children sees your Kerala post and fills the enquiry form: 6 nights, December, two adults and two children, mid-range hotels. The lead lands in your pipeline and is assigned to a salesperson. She opens the cost sheet, picks a Kochi-Munnar-Thekkady-Alleppey route, chooses a 3-star hotel in each place and a houseboat night, adds a sedan for the whole trip, and the sheet totals the supplier cost. Your standard markup is applied, GST is shown as per your accountant's setting, and a quote with photos, hotel names, inclusions, exclusions and cancellation terms goes to the family on WhatsApp within the hour.
They ask for a better hotel in Munnar. She swaps it, the price updates, and version two goes out. They accept and pay an advance through a payment link, say 30% of the package. The booking moves to confirmed, and your operations person sends hotel requests and records each confirmation number. The system schedules the balance for 21 days before departure and sends reminders, with a fresh payment link, until it is paid.
Two days before the trip, the traveller app shows the full itinerary, every voucher and the driver's name and number. During the trip the family can call the duty number from the app. After they return, a feedback request and a review link go out, and your report shows the margin earned on that trip after paying hotels, the houseboat and the cab.
