Marketplaces can earn a fraction of each sale while remaining exposed to the full loss. Learn how seller payouts, disputes, negative balances, reserves, and payment architecture determine who ultimately carries the financial risk.

Failed payments get blamed on customers who "lost interest," but most of that churn is really expired cards and bad retry timing wearing a disguise. This post breaks down why blind retry schedules waste recovery revenue, how decline codes should actually drive when and how you retry, and why the dunning email should be your last resort, not your first move.

A higher conversion rate feels like a win, but it only measures one moment in the customer relationship. This piece breaks down why initial conversion and net revenue retention tell two different stories, and how merchants who optimize reducing checkout friction without watching retention can end up moving their revenue leak downstream instead of closing it.

A plain language guide to agentic commerce: how AI agents actually pay for things, the protocols behind agent checkout, and where the system still breaks.

Two hundred economists, Nobel laureates, and AI lab leaders just signed a statement warning that AI could remake the economy faster than we can adapt — without saying what to actually do about it. I work in fintech, where that shift isn't hypothetical: underwriting, fraud detection, and support are already being absorbed by AI. This is my attempt at a more honest answer than 'act now.'

Mastercard has committed to 100% e-commerce tokenization across Europe by 2030, replacing the traditional card number with dynamic tokens tied to Click to Pay and passkeys. Three in five European transactions are already tokenized, and merchants using network tokens are seeing double-digit approval rate gains, not just fraud reduction. This piece breaks down what the 2030 mandate actually means: a growth lever for merchants who move now, and the quiet end of expired-card headaches and card-on-file risk for everyone else.

Flat fee autopay has been the subscription default for decades. AI is about to make that look outdated. From personalized pricing that adjusts based on your usage patterns, to metered billing that charges for what you actually consume, to AI agents that autonomously audit and cancel subscriptions on your behalf, the entire model is shifting. This post breaks down what's changing, what it means for consumers, and what subscription businesses need to do to stay relevant when inertia stops being a retention strategy.

The subscription model was built on a simple truth: people are busy and canceling is annoying. For years, that friction was a revenue strategy. But consumer awareness, subscription fatigue, and the FTC's Click-to-Cancel rule are dismantling the inertia that kept passive subscribers on the books. This post breaks down what shifted on both the consumer and regulatory side, and what subscription businesses need to do now to earn the renewal instead of just assuming it.

A chargeback feels simple from the consumer side: dispute a charge, get your money back. But for the merchant, that same transaction triggers fees, lost revenue, and a formal fight to prove they did nothing wrong; one they don't always win. This post breaks down how chargebacks work from both sides of the transaction, why friendly fraud is a bigger problem than most people realize, and what the real cost of "consumer protection" actually looks like.

Stripe, Visa, Mastercard, and Coinbase are reportedly teaming up to issue a stablecoin. If you don't follow payments closely, here's what's actually going on and why it matters.
