To do this part, you would either need to enable the nominal codes to be used in sales invoices (follow this post), and then edit the invoice, or do the journal, along the lines of:
If you date it the same as the invoice, that should make it clear if you go digging down in the chart of accounts report. However, bear in mind that only the net values are posted to a sales nominal code, so don’t include VAT in the movement (this is posted to a separate nominal code).
By default we post all sales to a generic nominal code, 4000 General Sales
, unless it’s changed. With rebilling a client, there is an option to post it to the same nominal code as the purchase invoice by ticking the “Contra Expenses” box during the process:
This will automatically allow the nominal code to be used for that sales invoice without the need to enable it.
