Contract Billings vs Quick Bill

SUGGESTED

We have a job that was opened as a quick bill project.  There has been an invoice generated with bill on this job.  Our project manager wants his contract amount, change orders, and invoicing to reflect on our job summary reports.

I was told to input the job as a contract billing so the amounts would show up.  they haven't because with it being quick bill, i cannot link the contract and change orders to a job.

My question is:  Would i be able to delete the invoice, then delete job and reenter the same job number and mark it contract billing?
