Can Someone Help me Understand Amazon's Reports Repository

I'm trying to understand what Amazon's Reports Repository (Summary) is showing me.

The report has 4 sections

• Income
• Expenses
• Transfers
• Tax

I'm trying to use this to calculate our NET profit at the end of the month. However, the "INCOME" section is different to what we see in the "Business Reports" line graph.

How would I calculate our NET profit based on the Reports Repository and taking into account VAT

Any help is appreciated
