SourceMedium vs Supermetrics

Why teams choose SourceMedium over Supermetrics

Supermetrics is spreadsheet-era tooling. It pulls marketing data into Google Sheets and Looker Studio — and that's where it stops. No warehouse, no SQL access (without Enterprise pricing), no attribution, no LTV, no cohort analysis, no customer segmentation, no product analytics. When your brand outgrows spreadsheet row limits and weekly refresh caps, you need a real data platform.

Approximately 50% of Supermetrics' ~200,000 customers are agencies. The product is built for marketing reporting, not ecommerce analytics.

Where the approaches differ

Spreadsheets vs a managed data foundation: Supermetrics feeds data into Google Sheets and Looker Studio. Google Sheets has row limits. Looker Studio slows with large datasets. SourceMedium writes to a managed BigQuery environment with included compute and direct table access. Tableau, dbt, Python, Hex, and other tools that support BigQuery can connect without export workarounds.

Weekly refresh vs a maintained platform baseline: Supermetrics Starter plans only refresh weekly. Growth plans get daily. SourceMedium's maintained platform baseline is complete through the prior day for supported standard connectors, with faster updates documented by connector when available. SourceMedium reconciles source differences and documents why a governed metric does or does not match a platform report.

Per-everything pricing vs one bill: Supermetrics charges per destination, per data source, per user — costs compound as your team grows. The April 2024 pricing restructure eliminated single-connector plans and caused 40–60% overnight price increases for many users. SourceMedium is a real data platform on one bill — no per-destination charges, no per-source fees, no per-user costs that penalize team growth.

Room to extend the model: SourceMedium's BigQuery foundation can include agreed finance, operations, or custom sources alongside marketing data. Confirm connector scope, included usage, and potential overages before signing.

Your reporting layer, not a vendor's: Fork any Looker Studio template, customize it, or build something new — same underlying data, no spreadsheet row limits, no performance degradation with large datasets. Your reports belong to you.

Data movement vs a maintained commerce layer: Supermetrics focuses on moving data into reporting destinations. SourceMedium includes seven reporting modules, attribution, and maintained LTV and cohort definitions on the same BigQuery foundation.

The graduation path: When brands outgrow Supermetrics, the typical path is either assembling an MDS (Fivetran + warehouse + dbt + BI) — inheriting all that complexity and cost — or moving to an integrated platform that replaces both Supermetrics and the tools it was feeding.

Support beyond a spreadsheet: For supported standard connectors, SourceMedium handles authorization guidance, historical backfill, modeling, reconciliation, testing, and dashboard setup. Your team grants access, confirms key definitions, and approves the validated outputs. Custom sources are scoped separately. Ongoing platform support is included.

AI that goes beyond marketing data: Supermetrics recently added AI features focused on marketing data. SourceMedium's AI Analyst can answer questions about LTV, attribution, cohort retention, or contribution margin using the maintained commerce foundation. Analytical answers can expose the underlying SQL.

When Supermetrics might be sufficient

Supermetrics works for agencies and small marketing teams that only need to pull ad spend data into Google Sheets or Looker Studio for basic reporting — and don't need attribution, LTV, cohort analysis, SQL access, or a data warehouse.
