I want to allow my client to edit submissions in a white label submission page

I want to allow a client to edit submissions, but I want it to reflect my brand rather than jotform. Is this possible?

It is not possible currently to allow for editing submissions through a white label submission page.  You can include and edit submission link in your email notification to allow for editing the submissions directly in the form:

Good News,

Jotform Enterprise is released and it supports hosting your data on your private dedicated server, "Single SignOn" and "White-labelling". You can get further info on https://www.jotform.com/enterprise/
