Billing report to report on payroll by paydate and not date processed

Billing is currently using the figures against when you physically processed a payroll rather than against the period it relates to.

Describe the Challenge

Currently if a payroll is processed outside of the applicable tax month this is not included in billing figures. For example, you processed an August payroll on 31st July, this will not report against payslip numbers for August. Fees are not accurate.
