Twenty years on a system built for wheels. Then they wanted to sell accessories.

The problem with software built exactly for you

A system designed around wheels knows what a wheel is. Diameter, width, bolt pattern, offset, finish. That precision is why it fit for two decades.

It's also why accessories were a development project. A different kind of product means different attributes, and different attributes meant changing code. The fit that made the system good is the same thing that made it rigid.

Two other problems had been building underneath it.

The stack stopped being maintained. Technology that no longer receives updates no longer receives security patches, and known vulnerabilities accumulate with no fix available. That same staleness made every new capability expensive to build. A mobile-friendly interface for the counter was never going to happen.

There was effectively no reporting. GZC couldn't easily see how inventory was moving. They also couldn't see who had changed what. Adjustments and corrections happened, but the record of them lived in people's memory.

Why LineraFlow

I built LineraFlow after twenty years of watching this pattern, so it starts from the opposite assumption: your categories will change, and the software shouldn't need a developer when they do.

Product categories define their own attributes, and those definitions are configuration rather than code. Wheels have diameter, width, bolt pattern, and offset. Tires have their own set. Accessories have theirs. Adding a category is something GZC does themselves.

Attribute schemas are versioned, so changing what a category tracks doesn't invalidate the products already recorded under the previous definition. Twenty years of history stays readable.

The platform underneath is current and stays current: browser-based, mobile-friendly at the counter, patched on an ongoing basis. It ships with the things the old system never had: dashboards, an append-only record of every stock movement, and an audit trail on every change.

Since going live

They add product types themselves. Accessories went in as a new category with its own attributes. No development work, no waiting on me.

Inventory is tracked across the full catalog, not only the product lines the original system was designed around.

Orders and inventory movements are auditable. Every stock change carries who made it, when, and why. “Who adjusted this?” has an answer now.
