Japan Expansion · Konbini & Bank Transfer

Problem

Japan's dominant payment methods, Konbini and bank transfer, carry async confirmation latency that our synchronous order system wasn't built for, requiring net-new flow design across inventory logic, order status communication, and edge case handling.

Solution

Designed end-to-end async payment infrastructure: no-hold inventory logic backed by LTV data, 3-stage customer communication, idempotent webhook handling, per-case bank transfer edge case logic, and full payment-state-to-reconciliation-event mapping with finance.

A PM's Deep Dive:

Cross-Border Payment Infrastructure

Why?

At Echo, building Japan market entry, async payment methods broke every assumption our sync order system was built on. I wanted to understand the infrastructure underneath—and what it actually means for product decisions.

What?

A PM-focused breakdown of cross-border rails: who's in the chain, how FX works, why settlement timing creates margin risk, and what local payment methods mean for market entry across 7 markets.
