Payment fees varied by tender and went unmanaged.
This marketing & margin audit surfaced $38k in recurring annual margin in a Retail business, evidenced, senior reviewed, and delivered in 5 days.
The business
A convenience store operator accepted a wide range of payment types across its estate, from cards and mobile wallets to scheme specific and premium cards. Payment fees were treated as a fixed, unavoidable cost of doing business, so the sharp differences in interchange and scheme fees between tender types were never analyzed or actively managed.
What triggered the audit
Payment fees as a share of revenue were higher than the tender mix seemed to justify, hinting the costlier tenders were overrepresented. The audit broke payment cost down by tender type across the estate, testing where fees were quietly eating margin and whether anything could steer the mix.
What the audit found
Payment cost varied far more by tender than anyone had managed for. Certain premium cards and scheme types carried materially higher interchange and processing fees than standard debit or account to account options, and on the thin margins typical of convenience retail, that difference was significant on every transaction. Because fees were treated as a fixed cost and never analyzed by tender, the estate was absorbing the most expensive payment types without any steering, surcharging where permitted, or negotiation, and the costliest tenders were overrepresented in the mix. The leak was invisible precisely because “payment fees” was accepted as an immovable line. Broken down and managed, the unmanaged tender fee differential was costing roughly $38k a year in avoidable processing cost.
What we changed
Broke payment cost down by tender type across the whole estate, making the interchange and scheme fee differential visible and manageable for the first time.
Steered customers toward lower cost tenders where permitted, through prompts, minimum spend rules and account to account payment options.
Renegotiated processing and scheme terms using the detailed tender mix data as concrete leverage with providers.
Made payment cost by tender a monitored metric, so a gradual drift toward the most expensive tenders is caught and corrected before it quietly erodes already thin retail margin.
The result
The published chart shows the blended card processing rate falling from 1.9% to 1.5%, a 0.4 percentage point decrease. The separately reported 2 point tender margin improvement is a different measure and is not presented as that rate movement. $38k a year recovered by managing payment fees that everyone had written off as fixed, an annual figure equal to 6× the $5,950 Audit + Sprint fee. For any high volume, thin margin retailer, that’s the trap: “payment fees” is accepted as immovable, so a costly tender mix erodes margin on every transaction unmanaged. If you’ve never broken fees down by tender, expensive payment types may be overrepresented and quietly taxing you. A fixed fee audit breaks it down in days and turns a “fixed” cost into a managed one.
