Currently as the 31st interim invoice is posted to a Time Account the system will convert it to a final invoice and finalise all the previous interims which is not wanted.
For example, if you have a client who has 3 direct debits set up for the different service lines (accounts, payroll, financial services), then 3 * 12 = 36, so even before the year is out the interim invoices will be finalised when the job is incomplete and the partner has not made a decision on the WIP and profitability for the client.
There are also examples of where a direct debit process may run for longer than 12 months to cover a piece of work.
The unexpected conversion of the interims to finals, erroneously affects the WIP and profitability, the automation has taken the decisions out of their hands. The problem surfaces in reporting, whereby they have to find it, and make lengthy adjustments to rectify it.

This is needed more this year as we bill payroll and furlough calculations separately. I am currently having to deliberately mispost to the wrong job to at least get the invoice onto the WIP ledger.
