ChartMogul
ChartMogul is the depth pick: the strongest cohort analysis in the category and 25+ billing integrations, free until you pass $120K ARR.
ChartMogul consolidates Stripe, Chargebee, Recurly, PayPal and a long tail of other billing sources into one normalized revenue view. Its cohort analysis and segmentation go deeper than anything else here, and the free Launch tier (up to $120K ARR) is the most generous entry point in the market.
It isn't instant, though. ChartMogul's help docs describe Stripe as real-time with a 10-minute processing window, while Braintree and HubSpot sync hourly and PayPal every 3 hours. Reviewers on G2 and Capterra (4.7/5, 44 reviews) praise the UI but mention sync discrepancies against their billing system, and some long-time customers describe repeated price rises.
