Hi jacobmorton_27,
There's no way to resend the invite to an alternate address for a self-employed client, the best option would be to cancel the license by going to the Cog > Billing & subscriptions > My subscriptions > Select the drop-down beside the client and select 'Transfer billing to client' and then re-create the account with the correct address.
If you have already entered data into the QBSE account we can then transfer the data to the new account, however, miles cannot be transferred and would need to be manually re-entered.
Thanks
