E commerce Script

I have very less knowlege of webdesign and development
So kindly bare with me… if am asking questions which you feel like is stupid…

Question is regarding https://codecanyon.net/item/karenderia-multiple-restaurant-system/9118694?s_rank=4

After purchasing the Script for app or website or for both, ill be able to download both and ill be able to integrate and use it with my domain… or how will i do that.
Is it like for few years ill be able to use the Script and later need to pay for further use? or
is it like they ill give the entire script and i can get a developer team to make necessery changes later?
is this script made of any frame work or is it custom-designed model?
Can we add or reduce something in this script?
If so will the developer team help me for the same or ill have to depend on a different team for this?
If in case of any issue with the Stock Script will i get support form the developer team? if so how will i contact them, please help, As i said before i have zero knowledge on webdesign. Kindly help…
