Marketing agency automated monthly reporting and kept 40 billable hours a month
15 retainer clients × 10 hours of manual reporting = two full-time staff doing work no one pays for. Here's how we ended it.
Industry: Marketing agency · Deployment: 4 weeks · Stack: GA4, Google Ads, Meta Ads, Search Console
The challenge
A marketing agency was burning 10–12 hours per month per client on data gathering and report writing across GA4, Google Ads, Meta Ads, and Search Console. With 15 retainer clients, that was two full-time-equivalents of work that couldn’t be billed.
What we built
We built a custom reporting pipeline that pulls data from each platform API nightly, stores it in a warehouse, and uses an LLM to generate a draft commentary per client — written in the agency’s house voice. Account managers review, tweak, and send. What took 10 hours now takes 90 minutes.
The numbers
- 40+ hours reclaimed monthly
- 85% of report drafts accepted as-is
- 12 days from brief to production
- £0 ongoing LLM cost (BM25 retrieval + caching)
Danial’s team delivered in four weeks what another agency quoted us four months for. Same scope. The AI layer was a bonus.
