The interface is genuinely well done. It’s fast, responsive, and easy to navigate, and the dashboards make it simple to explore MRR, churn, and cohort data without much setup. From a usability standpoint, it’s one of the better SaaS analytics tools I’ve used. Review collected by and hosted on G2.com.
ChartMogul’s job is revenue analytics. If the revenue numbers are wrong, the product isn’t doing the one thing it exists to do, no matter how good the interface is.
For us, the numbers were wrong. ChartMogul’s Chargebee integration overstated our recurring revenue by roughly $15,000 for a long period of time. When add-ons were removed from active subscriptions, ChartMogul didn’t record the churn, so those components kept counting toward MRR. Some subscriptions canceled in Chargebee also kept showing as active. This wasn’t the first data integrity issue we’ve had with them.
ChartMogul never reconciled its numbers against the actual charges in our billing system. We found the problem ourselves after years of discrepancies that didn’t make sense, by reconciling the two systems line by line. That reconciliation is the work we were paying ChartMogul to do.
They confirmed the bug and rolled out a fix. But their position was that they can’t guarantee data accuracy for their integrations and that customers are expected to validate their data at signup. For a product whose entire purpose is accurate revenue reporting, that isn’t an acceptable answer, and I don’t feel they treated the issue as seriously as it warranted.
ChartMogul has also been expanding into CRM, which doesn’t make sense to me. There are plenty of established CRMs, and that isn’t why anyone buys ChartMogul. It feels like a distraction from the core product. I’d rather see that effort go into making sure the revenue data is accurate. Review collected by and hosted on G2.com.
