If the company has two accounts, the first to do a good job of the internal account (including: invoices and no invoices of the documents)
Doing external accounts before going to the vouchers in the internal accounts to find the invoices.
In my daily work, I first distinguish between documents with invoices and without invoices,
Make a voucher for those with invoices and a voucher for those without invoices. (At the same time entered into the EXCEL voucher summary table)
Then there will be invoices of this voucher alone to a data basket basket, end of the month categorized processing.
Then the voucher with the invoice will be placed in a separate basket of information.
