Progress Billing

SOLVED

Good Morning,

I am new at a electrical contracting company.  I am going through aged receivables and have found a customer that apparently paid a deposit through progress billing. We have a copy of the check deposit in bank records but I cannot locate his job in progress billing.  He is past due to be billed for the completion of the job.  I did find a regular invoice for the whole amount, no payment has been applied.  According to the date on the check it was started before the only invoice that I can find in the system. Is there a way to pull any old progress billing? If it could be found from a back-up,, how do I access that?  My apologies on lack of knowledge.  I have never had any sage training so Ive been learning everything thus far on my own.

Thanks in advance for any advise!
