The answer to this question depends on whether you will be using the Procore + DocuSign© integration to request signatures or sign documents.
If you will be requesting signatures
Yes. If your Procore project has the Procore + DocuSign© integration turned ON (see Enable the DocuSign© Integration), you will need an active DocuSign© account. You will need to link your DocuSign© account to Procore in order to prepare a DocuSign© envelope and request signatures on documents from others. For more information, see How do I get a DocuSign© account?
If you are signing documents
No. If a Procore user sends you a request to sign a document in DocuSign©, you do not need a DocuSign© account. However, you will need to review the document and agree to your use of your electronic signature. To learn more about signing a document, see the Sign Documents category on the DocuSign© Support Site.
