Setting up your costs
Where do I put an influencer retainer?
On the Overhead page, with the category set to Marketing. Anything categorised that way counts as marketing spend on the P&L rather than as overhead, so it lands in CM3 with your ad platforms.
It is recognised the same way as any other overhead entry: recurring costs prorated daily, one-off costs on the day they are booked.
Did this answer it? If not, a person who knows the product will.
