Problem on box 6 of VAT

Thank you very much.
Also while we speak for VAT may i ask you another question.
According here VAT rates explained for purchases from EU you say to apply EC reverse charge (tax shift) on record of purchase.
My sales are from EU company registered to VAT.
Their invoices does not contain any VAT amount.
So you confirm is better on my records to appear VAT amounts (even they not appear on invoice) and then i reverse it back ?
By this way, all VAT amounts will appear on VAT return form on box 3.
Seems to me ok but I just ask you to be sure because my old accountant didnt appear any VAT amounts for these invoices on box 3.
So you think is better to proceed with your way and to show them on box 3 ?
Thanks.
