Yes, you can use your own contract instead of the Oyster contract. You can also download the Oyster contractor template and use this as a starting point.
To use your own contract ...
- In the first step of the contractor new hire flow, answer "No" to the question: "Do you want Oyster to prepare your contract for you?"
- Then upload your own, signed contract.
Currently we do not support uploading unsigned contracts for signatures on Oyster.
