How to build Polar revenue dashboards in Metabase
Polar is a merchant-of-record billing platform for developers and SaaS — subscriptions, one-time products, and digital benefits, with tax handled for you. Metabase is where you turn that billing activity into shared, trustworthy revenue dashboards. This guide covers two complementary paths: a lightweight MCP + CLI route that pulls live data with the Polar MCP server and loads a CSV into Metabase with the Metabase CLI for quick analysis, and a durable pipeline route that syncs Polar into a database so you can build MRR, net-revenue, and churn dashboards anyone can read.
How do you connect Polar to Metabase?
Most teams combine both routes: use the Polar MCP server and Metabase CLI route to pull live data and stand up a quick analysis, and the pipeline route for the revenue dashboards finance depends on.
Live data in, quick analysis out
Pair the official Polar MCP server (to look up live orders, subscriptions, and customers) with the Metabase CLI, whose upload command loads a CSV into Metabase as a ready-to-query table and model.
- Quick lookups like "which subscriptions renewed this week?"
- Loading a Polar CSV export into Metabase in seconds
- Spot-checks and one-off analyses without a warehouse
- Great for exploration, not governed revenue reporting
- Use a read-only Polar access token so analysis can't trigger writes
- CSV uploads are snapshots — refresh or move to the pipeline for history
Durable dashboards with history
Sync Polar via its API and webhooks into a database, then point Metabase at it.
- MRR, net-revenue, and churn dashboards the team relies on
- Product-mix and cohort analysis over quarters
- Joining billing data with product usage and marketing data
- Requires a destination database and a sync to maintain
- As merchant of record, gross and net differ — model both
- Reconcile against the Polar dashboard before anyone trusts the numbers
What can you analyze from Polar data in Metabase?
- MRR and ARR — recurring revenue now and its monthly movement
- Net revenue — what lands after Polar fees and tax (merchant of record)
- Churn and retention — customer and revenue churn, gross and net retention
- Orders and products — subscription vs. one-time revenue by product
- LTV and ARPU — value per customer and per product
- Refunds and disputes — their impact on net revenue
Which Polar dashboards should you build in Metabase?
MRR & net revenue
Recurring revenue and what actually lands after fees and tax.
- MRR and ARR right now (number + trend)
- Net revenue after Polar fees and tax (line)
- MRR movement: new, expansion, churn (waterfall)
- Gross vs. net revenue by month (dual bar)
Subscriptions & churn
The active base and where it leaks.
- Active subscriptions by product (bar)
- Customer and revenue churn (dual line)
- New vs. canceled subscriptions per month (bar)
- Renewals due in the next 30 days (table)
Orders & products
One-time and recurring sales across your catalog.
- Orders and revenue by product (bar)
- Subscription vs. one-time revenue split (pie)
- Checkout conversion (line)
- Discounts redeemed and their revenue impact (table)
Cohorts & LTV
Does each signup cohort pay back?
- Revenue retention by signup-month cohort (heatmap)
- Cumulative LTV by cohort (line)
- ARPU by product (table)
- Refunds and disputes by month (bar)
How do you use the Polar MCP server with the Metabase CLI?
Pair the Polar MCP server with the Metabase CLI for fast, hands-on analysis. Polar hosts a first-party remote MCP server that looks up live orders, subscriptions, and customers; the Metabase CLI's upload command loads a CSV into Metabase and creates a ready-to-query table and model. For analysis, scope the Polar access token to read-only.
Example workflow
- Ask the Polar MCP which subscriptions renewed or canceled this week, or list a customer's recent orders and benefits.
- Export the customers, subscriptions, and orders you want to keep as CSVs.
- Run
mb upload csvto load them into Metabase as tables and models, then build questions and dashboards on top.
Be honest about the limits
- The Polar MCP is great for live lookups — not for scheduled or audited revenue reporting.
- A CSV upload is a point-in-time snapshot; MRR movement and cohorts still need a warehouse sync, or refresh with
mb upload replace. - Scope the Polar access token to read-only so analysis can't trigger writes.
mb upload csvneeds an uploads database configured under Admin → Settings → Uploads.

Can you generate a Polar dashboard with AI?
Yes. Use the prompt below with any assistant that can run the Polar MCP server and the Metabase CLI. It works end to end: if Polar tables already exist in Metabase it analyzes those; otherwise it pulls the data over the Polar MCP, loads it with mb upload csv, then builds the dashboard — normalizing MRR and skipping cards it has no data for.
Create a polished Metabase dashboard for Polar revenue analytics.
Work end to end: get the data into Metabase if it isn't there yet, then build.
Goal: Help founders and finance leaders understand recurring revenue, net
revenue after fees/tax, subscriptions, churn, and product mix from Polar data.
Step 1 — Find or load the data:
- First, check what already exists in Metabase (search for Polar tables and
models). If durable Polar data is already present — synced from a warehouse or
uploaded earlier — use it and skip to Step 2.
- If nothing is there, pull it with the Polar MCP server using a read-only
access token: customers, subscriptions, products, prices, orders, and refunds.
Write each result to a CSV, then load it with the Metabase CLI — run
"mb upload csv --file <export>.csv" so each upload creates a table and a
ready-to-query model. Use "mb upload replace <table-id> --file <export>.csv" to
refresh an existing table instead of creating duplicates.
Step 2 — Inspect before querying:
Do not assume exact table names. Map the available raw tables into these
analytical concepts where possible: Customers, Subscriptions, Products, Prices,
Orders, Benefits, Discounts, and Refunds. Inspect the actual tables and column
names first.
Important:
- Build on whatever data is present; don't claim Metabase connects natively to
Polar — it reads a database or CLI-uploaded tables.
- Polar is a merchant of record: separate gross revenue from net (after Polar
fees and tax). Report net for what the business keeps.
- Compute MRR from active subscriptions, normalizing every price to a monthly
amount and converting to a single reporting currency.
- Separate subscription revenue from one-time product sales.
- Exclude refunds from net revenue and show their impact separately.
- Only build a card if its underlying column/metric exists in the data.
- A single CSV is a point-in-time snapshot: MRR movement and cohorts need
history, so build trend cards only if a warehouse sync or multiple uploads
provide it.
Dashboard title: Polar Revenue Overview
Sections:
1. Executive summary (KPI cards): MRR; ARR; Net revenue this month; Active
subscriptions; Net new MRR; Revenue churn %.
2. MRR & net revenue: MRR movement by month; Gross vs. net revenue.
3. Subscriptions & churn: Active subscriptions by product; Customer vs. revenue
churn; New vs. canceled.
4. Orders & products: Orders and revenue by product; Subscription vs. one-time
split; Checkout conversion.
5. Cohorts & LTV: Revenue retention by cohort; Cumulative LTV; ARPU by product.
Filters: Product, Price, Currency, Country, Date range.
Reuse the models Metabase auto-created from uploaded CSVs, or (for a warehouse)
create reusable models: modeled_polar_subscriptions, modeled_polar_orders, and
modeled_polar_mrr (a monthly per-subscription MRR model).
Output: Build the dashboard if you have permission; otherwise provide the exact
questions, SQL, model definitions, and layout. Include caveats for any metric
that cannot be calculated from the available data. Reconcile totals against the
Polar dashboard. Keep it practical, dense, and executive-readable. Avoid vanity
metrics.How do you build the Polar → Metabase pipeline?
For dashboards that need history and reliability, land Polar data in a database first, then connect Metabase to that database.
Connector options
- dlt / custom pipeline (free, code) — wrap the Polar API in a Python pipeline when you want full control over shaping and scheduling.
- Polar API (free, raw) — paginate customers, subscriptions, orders, and products into your own pipeline.
- Webhooks (free, events) — stream order and subscription lifecycle events into a table for near-real-time dashboards.
Notes
- Land raw tables first, then build clean models on top.
- Amounts are typically in the smallest currency unit — divide in a model layer.
- Separate gross (customer paid) from net (after Polar fees and tax) — they answer different questions.
- MRR is derived, not stored: build it from active subscriptions and normalized prices.
How should you model Polar data in Metabase?
Core tables
| Concept | Grain | Key columns |
|---|---|---|
customers | one row per customer | id, email, created_at, country |
subscriptions | one row per subscription | id, customer_id, product_id, status, current_period_end, canceled_at |
orders | one row per order | id, customer_id, product_id, amount, tax_amount, fee_amount, status, created_at |
products | one row per product | id, name, is_recurring |
prices | one row per price | id, product_id, amount, currency, recurring_interval |
Modeling advice
- Build a
modeled_polar_mrrtable: one row per subscription per month with a normalized monthly amount. - Model both gross and net revenue so finance sees what lands after fees/tax.
- Separate one-time product orders from recurring subscription revenue so they don't inflate MRR.
- Normalize all prices to a monthly figure and a single reporting currency.
- Reconcile modeled revenue against the Polar dashboard.
Which Polar metrics should you track in Metabase?
| Metric | Definition | Notes |
|---|---|---|
| MRR | Active subscriptions' normalized monthly amount. | Exclude one-time orders. |
| Net revenue | Gross − Polar fees − tax. | What the business actually keeps (merchant of record). |
| Revenue churn rate | Churned MRR ÷ MRR at period start. | Track separately from customer churn. |
| Net revenue retention | (Start + expansion − contraction − churn) ÷ start MRR. | Over 100% = expansion beats churn. |
| ARPU | MRR ÷ active customers. | Pick a grain and keep it. |
| Refund rate | Refunded orders ÷ paid orders. | Shows quality and fraud pressure. |
