The Challenges Advertising & Media Buying Agencies Face
These accounting challenges are especially relevant for agencies in Cardiff:
Media Buying Float & Cash Flow
You pay for media placements before clients pay you. Managing £100k+ monthly media float creates cash flow pressure that most accountants don't understand.
Commission vs Fee Recognition
Agency commissions (15% of media spend) and retainer fees need different accounting treatment. Mixing them creates tax inefficiencies and reporting confusion.
Campaign-Based Profitability
Which campaigns actually make money after creative development, production costs, and media placement? Most agencies are flying blind on true campaign margins.
