Self-signing means you are the only signer. Multi-party signing means routing the document to two or more people in order. Different problem shapes, different tools.
Self-signing
Quickest. Drop the PDF in, draw signature, save. Flint sign-pdf is built for this. No routing, no audit certificate needed, no waiting on counter-signers.
Multi-party signing
Document routes to signer 1, then signer 2, then signer 3. Each gets emailed when it's their turn. Reminders go out. Final document is delivered to all. DocuSign, Dropbox Sign and SignNow handle this; Flint does not.
When you need multi-party
Contracts with both client and contractor. NDAs between three companies. HR documents needing employee + manager + HR. Anything where one missed signature stops the process.
Best for…
Self-signing: Flint. Multi-party routing: DocuSign or similar.
FAQ
Can I email a Flint-signed PDF for counter-signing?
Yes — recipient signs it in Flint or any signing tool and emails it back. That is a manual two-party flow, not routed.
Do I need DocuSign for two-party?
Only if you want automatic routing and reminders. Manual email works for low volume.
What about three or more parties?
Manual gets fiddly. Use a multi-party tool.
One signer: Flint. Many signers in order: DocuSign or similar.
