Payment Daniel Jasinski
The Payment Economist. Founder of the Payment Economics Institute. Publisher of The Payment Economics Journal.
Twelve years. Five companies. One gap that never closed.
Daniel started in B2B payments as an intern and spent the next twelve years working his way across five companies: TIS, Kyriba, Calculum, Raistone, and AP Copilot. Treasury management. Supply chain finance. Working capital platforms. Early pay programs. Virtual card acceptance. Every company was selling a different product. Every company was, underneath the product, selling the same economic value: the return available when organizations make better payment decisions.
None of them had a shared language for it. No common metric. No defined owner inside the organizations they sold to. Practitioners who understood the economics intuitively had no framework to stand on when making the case to leadership. The value was real. The discipline to measure and manage it did not exist.
Payment Economics is the discipline Daniel defined to fill that gap.
The framework
Payment Yield equals Capital Return multiplied by Supplier Acceptance. That formula is the foundation. Capital Return measures what an organization earns per dollar paid through yield-generating methods: virtual card rebates, early payment discounts, float. Supplier Acceptance measures what percentage of spend actually flows through those methods. The relationship is multiplicative: a company earning 1.5% Capital Return on 20% of spend produces 0.30% Payment Yield. The same company at 60% Supplier Acceptance produces 0.90%. Same return rate. Three times the yield. That leverage is where most of the uncaptured $289 billion lives.
The practitioner who owns Payment Yield as a KPI, manages the supplier base as a portfolio, and coordinates across Treasury, AP, and Procurement is the Payment Portfolio Manager. That role, and the work it does, is what the journal and the certification are built to support.
The journal
The Payment Economics Journal publishes weekly. Each issue takes one concept, a method, a metric, a supplier conversation, a measurement framework, and applies it to real data with real math. 19 issues published. 1,000+ subscribers across finance, treasury, and accounts payable at organizations including Amazon, DuPont, and BP. The journal is where the discipline develops in public, one issue at a time.
The book
Payment Economics: The Foundation is published on Amazon. It covers the origin of the discipline, the complete Payment Yield model, the mechanics of Capital Return and Supplier Acceptance, and the practitioner role that owns it. Written for the finance professional who already suspects that payment operations should generate more value, and needs a structured framework to prove it and act on it.
The proof
AP Copilot became the first U.S. platform to deliver Mastercard Commercial Direct Payments, achieving 50% virtual card acceptance, 10x the industry average. The result demonstrates what happens when Payment Economics methodology meets operational execution. Supplier Acceptance at that level produces real, measurable yield. It is not theoretical.
The certification
The Payment Economics Foundation certification covers the complete framework across six modules and concludes with a proctored exam. It produces a verifiable credential for finance and payments professionals who want to formalize their fluency in the discipline, and practitioners who want to demonstrate it.
Advisory
Payment Economics advisory engagements are available for organizations ready to implement the framework directly. A four-to-six week assessment maps current Payment Yield, identifies Supplier Acceptance gaps, benchmarks against industry data, and delivers a prioritized action plan with projected financial impact. For organizations ready to commit to implementation, a Yield Partnership structure ties advisory fees to the incremental yield produced.
