I run an Italian leather accessories and handbag e-commerce business in Milan... We outsourced our ad management to a local digital agency. In their monthly performance report for last month, ad spend was listed as 2,450 EUR and their management fee was 600 EUR. However, when I sum up the invoices generated via Meta Business Manager and submitted to accounting the total comes out to 2,180 EUR.
When I questioned the 270 EUR difference, the agency told me it was down to billing thresholds, currency conversions, and month-end closing dates but it just doesnt sit right with me. like meanwhile my Italian accountant insists that for the tax authority (Agenzia delle Entrate) we must declare the exact invoice total issued by Meta Ireland, and that an agency report doesnt qualify as an official tax document.
How do I do a step-by-step reconciliation between the spend in the agencys report and the official invoices issued directly by Meta? Is this discrepancy normal, is the agency tacking on an undisclosed margin or is it merely a technical billing cycle lag?
