client listing

[Nicolas Severyns]

Dear all,

For my trimestrial Belgian VAT declaration I need to make a client
listing and a listing of all invoices made out during the last
year/trimester.

I only find an option to make a report for one client. 

I know that all the data I need is in my Gnucash database, but I don't
know how to get it out of it. 

Do I have to make a custom report? Are there any tutorials on the
internet? Any other tips?

Thanks for all possible information,
