Billing
The missing purchases report is free. Sending to GA4 needs the Standard plan at $19 per month, which includes 200 events a month.
What is free, and the Standard plan
| Free | Standard | |
|---|---|---|
| Price | $0 | $19 per month (14-day free trial) |
| Missing purchases report | Included | Included |
| Sending to GA4 | — | 200 events a month included |
| Dry run (records without sending) | — | From the start of the plan until you approve sending |
Above 200 events
Only events beyond 200 in a billing cycle are charged, one by one. The price per event goes down as the count goes up. There is no cap on usage charges. The Billing page in the app shows this cycle’s estimated charge at any time.
| Events in the cycle | Per event |
|---|---|
| 1–200 | Included |
| 201–1,000 | $0.05 |
| 1,001–5,000 | $0.03 |
| 5,001 and above | $0.02 |
650 events in a month: $19 + (650 − 200) × $0.05 = $41.50
1,800 events in a month: $19 + 800 × $0.05 + 800 × $0.03 = $83

Nothing is charged during the 14-day free trial or the dry run before you approve sending. Your Shopify invoice shows the final amount.
What counts as an event
- Each purchase sent to GA4 is one event, whichever channel the order came from.
- If you have turned on refunds or cancellations, each one sent is also one event.
- Nothing is sent until you approve, so the count stays at zero.
- Orders that were skipped or failed are not counted.
Checking your bill
The Billing page in the app shows this cycle’s count, the estimated charge, and a daily and monthly usage log. Shopify bills the charge with your Shopify invoice. The final amount is under Settings › Billing in the Shopify admin.
Stopping
Uninstalling the app also ends the plan. To stop sending only, use Pause under Settings. The monthly fee still applies while paused.
