u will get a paper called PBO with dealership stamp without booking number on submission of full payment thru PO/bank draft.
it will have ur details alongwith details of payment made by you against the product booked.
Normaly from 4-7 days, PSMCL issues a booking number with tentative delivery date which is reflected in the booking portal and visible to dealership.
this booking number is the evidence that ur PBO has been processed by PSMCL and manufacture process has been initiated.
U r supposed to keep in touch in with dealership untill u get the updated PBO with booking number and TDD.
It is important because prices applicable at the date of booking by PSMCL shall be reflected on ur invoice.
Now u can call PSMCL and provide ur details to confirm that car has been booked with them and thats all.
u can contact again ur dealership near the TDD to know when the car is arriving with them.
