I like how easy it is to add signing documents and collect payments. In my case, I use it through Salesforce, and the integration works almost seamlessly. I've rarely had issues. Review collected by and hosted on G2.com.

I don't like how I need to edit everything in Sertifi itself (payments and documents) for changes to be accurately reported. I wish I could edit items directly though Salesforce and then have them updated in Sertifi + reported on accurately. Review collected by and hosted on G2.com.
