Hi WillZ,
Is that useful what you are looking for?
The vendor account is recorded with the voucher and with standard reporting tools (power bi, electronic reporting, etc.) you can easily identify the vendor name.
When you say that you want to know the source of the expense, does the 'source' really depend on the vendor or on the products / services delieverd?
I am thinking about a cash flow statement scenario where the nature of the goods/services purchased defines for what you used the money.
As an example, you can have a single vendor from which you purchase a machine that is classified as 'investment' expense in the cash flow statement.
At the same time you can buy screws or other material from the same vendor that is used in production. This other purchase would be classified as 'operational' expense in the cash flow statement.
The vendor / vendor name is in this example not sufficient to differentiate between 'investment' and 'operational' type expenses.
Hope this helps.
Best regards,
Ludwig
