our call

Start with OrderMetrics — highest vibe code, weakest moat.

Cometly

Building a basic UTM recorder with a dashboard takes a weekend. Replicating multi-touch attribution, server-side CAPI event deduplication, and maintaining ad platform API connections against breaking changes across Meta, Google, and TikTok is a full-time engineering effort.

you can rebuild

  • UTM parameter capturing and first-party cookie tracking scripts
  • First-touch and last-touch attribution SQL query logic
  • Analytics dashboard displaying CAC, ROAS, and ROI per ad campaign
  • Shopify webhook receiver for sales conversion ingestion
  • Basic server-side event payload generation

what you lose

  • Turnkey client/server event deduplication across Meta, TikTok, and Google
  • Automated token refresh and API schema maintenance across ad platforms
  • Pre-packaged identity stitching across multi-device user journeys
  • Ad spend ingestion pipelines that handle API rate limits and currency conversions
  • No-code Shopify theme app integration

real moats

  • Maintained native integrations with rapidly evolving ad platform APIs
  • First-party identity graph infrastructure optimized for browser privacy limits
  • Turnkey server-side tracking bypassing Safari ITP and ad blockers without custom DNS configuration

OrderMetrics

OrderMetrics aggregates external ad spend, shipping rates, and payment gateway fees to calculate net profit. The internal math is trivial (Revenue minus Expenses), but maintaining OAuth connectors and API deprecation schedules across Meta, Google, and TikTok requires ongoing engineering maintenance.

you can rebuild

  • Real-time net profit dashboard
  • COGS tracking by SKU with historical cost adjustments
  • Ad spend aggregation across Meta, Google, and TikTok Ads
  • Transaction fee rules per payment gateway
  • Product and variant-level contribution margin breakdown

what you lose

  • Pre-built third-party API connectors with automatic OAuth refresh logic
  • Automatic backfilling of historical marketing metrics upon integration
  • Zero-maintenance schema updates when Facebook or Google updates API versions
  • Built-in multi-currency auto-conversion engine
  • Out-of-the-box alert system for sudden profit drops or margin erosion
