What do you mean by “the list of integrations we have is white labelling” …? I’m not sure if you need clarification on what an integration is, but either way this can’t be a good sign.

Hi Zeke_Ducker, Thank you for looking at our Product. Right now the list of integrations we have is White Labeling. We don't allow custom CSS, but we do have custom CNAME which is available for Tiers 2,3,4, and 5. Please click on link for details: https://proposa.io/features/white-labeling/

Hi, We have "white labeling" integration, where you can add your custom domain/sub-domain for your proposals. No other third party integration available right now.
