Hi all.

I need some advice.
Our Statements and some older Remittances are totally haywire. I took over last year August from the company's previous book keeper, who, did not know, or did not care. Anyway...

The problem I think is/was with linking the payments and receipts from the cashbook to the correct Customer Invoices/Supplier Invoices.
Now we have some statements/remittances that show a 120+ days total(debit and credit), even though the payment/deposit does reflect on their accounts. (because they have not been linked, I think)

Keep in mind, this is form August 2015 and back.

I've tried correcting the link, but I don't know how to do this with lets say a invoice done in 2014.

Is there any other way that I can get these statements/remittances to be true and correct again and not look totally unprofessional?

Please, please, please. I need some help
