Payments, straight talk.
Strategy and plain answers for merchants others won’t board — dual pricing, why processors freeze accounts, what “high-risk” really means, and how Kadima does it differently.
Embedding payments with Claude Code: a Kadima walkthrough
The real integration end to end — onboarding, Hosted Fields tokenization, the charge, signed webhooks — and the four places AI-written code gets our API wrong.
DevelopersWhat AI gets wrong when it writes your payment code
AI-directed engineering, applied to payments. Seven failure modes — money units, idempotency, webhook verification, PCI scope — with the wrong and right code side by side.
Digital commerceWhop vs Shopify: which fits a digital business?
The real dividing line isn’t features — it’s whether your sale ends or keeps going. And when you want your own merchant account instead.
High-riskWhat is a high-risk payment gateway and do I need one?
Kadima's founder on what actually makes a business high-risk, why the label is good news, and the volume at which you should make the move.
StrategyWhy modern platforms need more than a generic processor
Generic onboarding is easy until a business hits real risk, vertical complexity, or partner monetization. How to think payment strategy through before it becomes the bottleneck.

High riskStripe shut you down? Here’s what to do next
An aggregator can close your account overnight and hold your funds. Here are the exact steps to recover fast — and how to land with a processor built for your business.
UnderwritingWhy payment processors shut businesses down
Stripe, Square, and PayPal approve first and underwrite later — so growth and chargebacks can trigger a freeze. Here’s why it happens and how proper underwriting protects you.
UnderwritingWhat makes a business “high-risk” — and what it really costs
The label affects your rates, terms, and approval odds — but it rarely means what merchants think. Which verticals carry it, what it costs in rates and reserves, and how to get approved.
UnderwritingWhat is a rolling reserve? How much is held, and for how long
A slice of every settlement, held back and released on a delay. The plateau arithmetic nobody shows you, what drives your percentage, and how to get a reserve reduced.
ComplianceDual pricing signage & legality: a merchant’s guide
Dual pricing lets you display separate cash and card prices to offset processing costs. Here’s where it’s legal, how the card networks regulate it, and how to stay compliant.
StrategyShould you use dual pricing — and how do you roll it out?
