One way
One address in Dongguan to one address in Shenzhen, or the reverse, quoted per vehicle rather than per seat. It suits a group that is staying in Shenzhen overnight, or a team that is travelling north and returning by high-speed rail.
Round trip
Both legs in one booking with the same coach and driver. The driver waits in Shenzhen for the meeting to finish, so an overrun costs nothing but time rather than a second vehicle being called out.
Day charter
The normal pattern for a Dongguan to Shenzhen day: two Dongguan pick-ups, a Shenzhen head office, a customer visit and the run home. The vehicle and driver stay with the group for the day, with the waiting between stops inside the quoted price.
Monthly staff shuttle
A fixed shuttle is quoted monthly, per vehicle, for the same coach and driver on the same schedule every day. Send the route, the number of runs a day and the headcount, and the monthly figure is set in writing before the first run.
Included and extras
Driver, fuel, tolls and vehicle insurance are in the price. Driver meals and accommodation and parking fees are not, and they are listed separately on the quote so the invoice matches the agreed figure at the end of the month.
