Agency accounting

What is marketing agency accounting?

Marketing agency accounting is bookkeeping and financial reporting for creative, digital and marketing agencies. It usually means tracking revenue and costs by client, paying freelancers and filing their 1099s, separating pass-through media costs from agency revenue, and managing cash between client payments.
