Most teams pick an ecommerce analytics tool the same way they pick a coffee shop: whichever one they walked into first felt fine at the time. A sales rep runs a slick demo, the pricing page seems reasonable, and the decision gets made in a week. Then 60 days into onboarding, someone on the team realizes the tool doesn't actually pull Amazon settlement data the way they assumed, or that "real-time dashboards" means a 24-hour lag.
