ChartMogul
ChartMogul is the natural landing spot for Chartsy users on Paddle: 25+ billing integrations, the deepest cohorts in the category, free under $120K ARR.
If Paddle or BigCommerce revenue is why you picked Chartsy, ChartMogul is the only tool on this page that keeps both covered while adding serious analytical depth. It normalizes Stripe, Paddle, Chargebee, Recurly and a long tail of other sources into one revenue view.
Its cohort analysis lets you slice retention by signup month, plan, geography and custom attributes. No prompts, no per-question budget.
It's a heavier tool than Chartsy, and slower to feel at home in; Capterra reviewers (4.7/5, 44 reviews) praise the visualizations but mention sync discrepancies against their billing systems, and some long-time customers describe repeated price rises. ChartMogul's own help docs put Stripe data behind a roughly 10-minute processing window, with PayPal at 3 hours.
