Fastest way to generate a pdf?

[Aurelien]

Hi there

I’m working on a quote generation app.
This one have many (many, many…) tables related to each other, and evenly child-parent relationships, and some images as well.

Generating such a pdf lasts around 1,5 minute from the moment I sync, which is quite a long time for my users.
Is there a fastest way to generate it, using zapier for example ?

Many thanks in advance for your insights !
