B2B Payment Rewards Optimization Engine
A SaaS platform that automatically calculates the optimal credit card plus passthrough service combination for each ACH vendor payment, maximizing net rewards after fees. The platform would maintain a database of card rewards rates and passthrough fees, recommend the best payment path per transaction, and negotiate volume-based fee discounts with providers like Plastiq and Melio on behalf of high-spend clients.
これが重要な理由
You run a business spending hundreds of thousands or even millions every month on vendors like media agencies who only accept ACH. Every other payment in your business earns cash back through credit cards, but ACH offers nothing. You have tried card-to-ACH passthrough services, but their processing fees eat up the rewards, making the whole exercise pointless. You know that with the right card and the right service, the math could work in your favor, but figuring out which combination is optimal for each payment is a manual spreadsheet exercise nobody has time for. You want a tool that just tells you the best way to pay each vendor to maximize net savings, automatically.
- · Finance and accounts payable teams at mid-market to enterprise businesses spending $200K+ monthly on ACH-only vendor payments, particularly in marketing, advertising, logistics, and professional services向けに構築。
- · 最も可能性の高い収益化モデル: SaaS subscription with success fee (percentage of net savings achieved)。

失敗する可能性がある理由
自己反論 — 最も重要な信頼のシグナル
- 1Passthrough providers like Plastiq and Melio may not offer APIs, meaning the platform cannot automate payment execution and becomes just a recommendation engine that users may not consistently follow.
- 2Card networks could restrict or penalize manufactured spend through passthrough services, eliminating the rewards arbitrage opportunity entirely and invalidating the core value proposition.
- 3The target customer base is sophisticated enough to eventually do the optimization math themselves or negotiate direct deals, limiting long-term retention and willingness to pay ongoing fees.
エビデンスの概要
AIがこのインサイトをどのように統合したか — 逐語的な引用はありません
Approximately 5 commenters confirmed that ACH lacks the interchange revenue that funds credit card rewards, making direct cash back structurally unlikely. Multiple users independently identified Melio and Plastiq as existing card-to-ACH passthrough solutions, but 4 commenters noted that their processing fees often cancel out rewards. One commenter pointed out that the math depends on the specific card used, with signup bonuses or higher rewards rates potentially making it work. The original poster spends 400K to 1.5M monthly, representing an extremely high-value customer for any solution that delivers even fractional savings.
