Frequently asked questions
What is a credit?
One credit is one signed document. Upload the PDF, have it signed and download it with its audit certificate. Credits never expire.
Is the first document really free?
Yes. Every new account gets one credit. You do not need a credit card for it.
Do signers need an account?
No. Signers open the link and sign. They need no account, no subscription and no app.
When should I choose Pro?
When you regularly send many documents for signing or use the API. Pro has a fixed monthly price with no limit on the number of documents. For individual projects, packs are enough.
