Depending on the choice under "Who will sign the contract" section in your contract Draft you will have to Send and sign if you are one of the signees of the contract yourself and there are additional recipients.
When you create a contract on Contractbook, the default setting is that you sign with an SMS code (SMS verification signature type) and that you as the sender sign the contract first. Once you have signed the contract it is automatically sent to the recipient.
If you are happy with this just scroll down to the bottom of the contract and press Sign and send.
A code will now be sent by SMS to you. The code you receive via SMS must now be inserted into the verification field and when you press Verify & sign, the contract is signed and sent to the recipient/s.
Once everything is in order, just lean back and wait for the recipients to sign. If they need some help, you can send them this article: Receiving and signing a contract.
If you do not want to sign the contract first, or if you have several signees, you can fully customize the signature order.
