Unfortunately, our platform does not support international accounts yet. To sign up for an account, both business and client members will need to use a US address. If you're an RPC business member trying to issue a contract or invoice to a client outside of the US, feel free to send a guest contract and invoice. Your client will be able to execute items as a guest.
We are working to expand soon and will keep you posted on any and all updates on that front! Watch out, world :)
