Currently, you need to be invited to sign up to Luna from IN-SYNC.
Once you have your invitation email, you'll need to click on the create account link.
This will take you to the following screen where you'll need to create a password.
Once you have successfully added a password to your account you will need to fill out the relevant information on the next few screens including your contact details, bank details (so we can pay you) and tax information as well as having the chance to add optional services such as the Self Assessment and FRS VAT schemes.
Once all of your information is filled out, you will see a final screen where you can complete the process to 'Signable' to digitally sign your contract with IN-SYNC Luna.
