Are you supposed to pay whole amount before delivery?

Hey, I’ve been riding since 2020, but recently moved to a new city and ended up buying an Ather 450X!

My first scooter was an electric scooter from hero electric , followed by another from hero and then a few ICE ones in the span of 4 years. I am younger so it’s always my dad who ends up doing the financing and purchases.

This time though since my father isn’t here, and since this is the first time I’m purchasing on my own , I ended up going for Ather since I’ve been a fan of theirs and had it in mind if I buy a 2 wheeeler it’s going to be Ather.

At the experience center they expected me to either finance it or pay in full before they can start processing. Which , since I was in a need of , complied. Post payment they provided me the electronic copy from the machine and mentioned it was too late so I can expect the invoice by tomorrow. Having not much leverage I complied, and while it didn’t sit well with me I had already paid and it was late 9PM.

Next day I went to the center to get an invoice which they delayed till evening. I finally got my invoice but it didn’t have any breakups or mentions about the addons I had actually ended up opting for.

I know these all look weird but I see my Ather on the app and got calls from their team to confirm the purchase. This is more of a retrospection as in what is the expected behaviour and flow ? I see some people mention that you should instead be paying only booking amount and pay in full once they hand it over to you. I asked my father the same but he mentioned paying the full amount is the right one. Since I’m very new to owning a vehicle I really would love to know about the anti patterns and dos and don’ts!
