Customer relationships in logistics rarely follow a simple model. A single client might include dozens of brands, multiple procurement teams, and overlapping shipping locations. Some buyers need access to one product line. Others oversee everything across a national footprint. And account managers at the logistics provider need visibility into all of it.

The legacy notification system built in PHP was not designed for that kind of complexity. It had no concept of tenants. No way to scope visibility by brand or role. And no guardrails to prevent cross-account leakage.

Every change required engineering time. A single message update could take weeks to deploy. Debugging delivery failures meant chasing down logs across systems. Worse, business-critical alerts were sometimes missed or sent to the wrong place entirely.

Internal coordination was also suffering. Every customer is paired with an account manager, and notifications needed to reach both sides without data leakage across accounts. But the legacy system could not model those relationships. Teams were left flying blind, with no scoped visibility into the tenants they managed.

Notifications had become a liability. They needed something purpose-built for how B2B actually works.
