What's the most important field on a contractor invoice?

A clear due date. Invoices without a specific due date get paid 'whenever' — invoices with one get paid on or near it.

Do I need to put my registration number on the invoice?

Yes, where applicable — ABN in Australia, EIN in the US. It's often a legal requirement and it makes the invoice look professional, not improvised.
