Two sole trades - one business - one Clear Books account?

Hi.

Myself and my partner individually submit our self-assessment tax returns to HMRC as sole traders albeit with the same property income.

Is it possible to have an upgraded Clear Books account for both of us, with one login and monthly fee but with separate areas for us? We are equal partners in our property 'business' and share the vast majority of income and expenditure 50/50. Or will he need a completely separate account with you as he is effectively a sole trader like me?

Thanks, Neil.
