Pro Tips

  • *Start with one sales channel and one platform, then expand after you prove a repeatable ROI narrative with 3 to 5 reference customers.
  • *Instrument every workflow with before-and-after metrics like AOV, conversion rate, return rate, and pick-to-ship time to validate impact quickly.
  • *Price on a value proxy that finance teams already track, such as per-order optimization, retained subscriber revenue, or usage-based tiers.
  • *Bake in compliance from day one, including GDPR data minimization, TCPA consent logs for SMS, and accessible UX that meets WCAG guidelines.
  • *Ship native integrations for the top tools in each stack segment first, and provide a dead-simple migration path to beat incumbent friction.
