Thank you, I will try this soon. It turned out, that all the invoices i manually created and applied payments to, are doubling my income. As of this morning, i found out that i needed to link transactions. Although, this will appear difficult now given this has been ongoing since January and most deposits are made in bulk deposit slips. 

To fix this issue and clean up my total revenue, i intend to reverse/delete every invoice and payment made since the beginning of the year. Any helpful tips?
