Legacy ERP Modernization

01 / The Challenge

Veridian ran on a heavily customized, 20-year-old ERP that only two employees fully understood. Field crews carried paper work orders; finance spent nine days closing each month; and every integration was a fragile point-to-point script.

02 / Our Approach

The thinking behind the build

The tempting move rewrite the ERP was the one we ruled out first. Twenty years of undocumented business rules made a big-bang replacement a bet-the-company risk. Instead we mapped the system into seams: which capabilities could be extracted cleanly (field service, work orders), which had to stay put for now (general ledger), and what data-ownership rules would keep both worlds consistent during the transition.

Each extracted service ran in parallel with its legacy module until the numbers matched for a full cycle only then did the old module go read-only. Momentum came from sequencing: field-service first, because paper work orders were the most visible pain, and its success funded organizational patience for the deeper financial modules.

03 / The Solution

What we built

Rather than a high-risk rip-and-replace, we modernized incrementally: an API layer over the legacy core, field-service and work-order management extracted into modern cloud services with mobile apps, and automated financial data flows retiring legacy modules one by one as replacements proved themselves.
