In this analogy the ERP system is the Stripe plumbing that simplifies it for the endpoints (factory logistics manager, salespersons etc) just like Stripe does for its endpoints (merchants and customers).
You might find that re-implementing Stripe is not so simple because of the nightmares of naturally-grown international payment networks. Similarly, implementing an ERP system over an F500 company's logistics/manufacturing/sales pipeline that grew in a complex nightmarish fashion through M&A and diverse international legal/tax/regulatory frameworks.
