About PaymentBrief

PaymentBrief is a publication covering payments infrastructure, fintech strategy, and the role of AI in money — with a particular focus on Southeast Asian markets.

Most payments coverage falls into two categories: wire-service announcements that relay press releases unchanged, or academic research that reaches practitioners too late to be useful. PaymentBrief sits in neither category. The goal is briefings that read like they were written by someone inside the room — because they were.

What we cover

The operational realities of payments: PSP contracts and what's actually negotiable, authorisation rate optimisation, fraud and chargeback economics, cross-border payment infrastructure, and how AI is actually deployed in production payment stacks versus how it's described in vendor keynotes.

Southeast Asia receives disproportionate focus because it's where the gap between public coverage and operational reality is widest. The region has some of the world's most sophisticated payment infrastructure (Thailand's PromptPay, Singapore's PayNow) sitting alongside markets where basic acquiring reliability is still a competitive differentiator. Understanding both ends of that spectrum is essential for anyone building or operating in the region.

Who reads this

Payments operators, fintech founders and product managers, investors evaluating the sector, and merchants who process enough volume that contract terms and authorisation rates materially affect their unit economics. The content is written for people who need to act on what they read.

Consulting

PaymentBrief also takes on a limited number of consulting engagements — payments strategy, PSP selection and contract negotiation, authorisation rate optimisation, and market entry into Southeast Asian markets. If you're working on a payments problem and want a second opinion, get in touch.
