Automated End-of-Month Client Reporting for a Digital Agency (Saving 35h/Month)
LookADev built a multi-API data aggregation pipeline using n8n, PostgreSQL, and Next.js for a UK digital marketing agency, saving 35 hours per month of manual reporting toil and automating Day-1 client deck delivery.
4 performance marketers spent the first 5 business days of every month logging into 6 disjointed ad platforms (Google, Meta, LinkedIn, GA4, Shopify) to manually screenshot, copy-paste, and assemble monthly client slide decks.
£28,000/year in skilled analyst wages wasted on copy-paste reporting, paired with client churn risk when reports were delayed past the first week of the month.
API fragmentation and lack of a deterministic aggregation pipeline: off-the-shelf BI tools charged exorbitant per-seat connector fees and produced generic, unbranded dashboards clients ignored.
Deterministic n8n orchestration pipeline fetching spend, conversions, and ROAS across all ad APIs nightly into PostgreSQL, powering a branded web dashboard with automated PDF generation delivered on Day 1 of every month.
End-to-end month-end client reporting automation: centralized multi-channel ad data and automated delivery of custom client decks without touching a spreadsheet or slide template.
35 hours/month saved (£28,000/year in billable analyst capacity) plus guaranteed Day-1 delivery eliminating client churn.
35 hours saved every month, 100% of client reports delivered on Day 1 at 08:00 AM, and client retention increased with NPS jumping +28 points.
