"Stability" is sometimes a warning sign rather than a reason to stop. Mature B2B enterprises face constantly shifting market dynamics: buyer purchasing habits are changing, competitors are adopting new tools, and new regulatory and compliance requirements keep emerging (such as the EU's PPWR packaging regulation). If the platform lacks flexibility—for instance, can't quickly add new market-based pricing, can't support new payment terms, or is difficult to integrate with other internal systems—the company will begin using manual processes to bridge gaps the system can't fill, accumulating hidden operational costs. Therefore, the core standard for selecting or evaluating a platform in the mature phase isn't "sufficient for now," but rather "how easy are changes?"—when the market demands you adapt, how quickly can your tools keep up.
