The story leads with a number going up (4% acceptance rate) alongside a cost saving, making it a close call between Breakthrough and Efficiency; the headline leads with the acceptance uplift so Breakthrough wins. The before-state is concrete: false declines caused by incomplete data, rigid retry logic, and a one-size-fits-all gateway that obscured decisioning. The mechanism is specific enough to follow: migrating to a unified API with Intelligent Acceptance, Network Tokens, and issuer-aware retry logic, then using Checkout's reconciliation API for real-time visibility to tune strategies by region and issuer.
Anchor the results section on two distinct metrics that appeal to two different buyer personas simultaneously: the 4% acceptance rate speaks to the revenue owner, while the £1M+ annualized saving speaks to the CFO. Leading with both in the headline doubles the story's relevance without diluting either number.
