Case Study: Environmental Science Associates achieves 25% reduction in unbilled revenue and improved cash flow with EleVia Software

Environmental Science Associates Improves Cash Flow by Reducing Unbilled Revenue by 25%

Environmental Science Associates, a national environmental consulting firm, was struggling with a largely manual invoicing process in Deltek Vision that produced long Days Sales Outstanding (DSO) and poor visibility into invoice status and project manager responsiveness. To tighten controls and improve accountability, ESA implemented EleVia Software’s Electronic Invoicing (EI) platform, integrated with their existing Deltek Vision system.

EleVia Software provided a centralized electronic invoicing solution for entering, tracking, and storing invoices with an auditable review history, which increased transparency and PM accountability. As a result, ESA reduced unbilled revenue by 25%, cut DSO from 45 to 35 days, increased monthly invoice volume by 25% (individual biller productivity up ~20%), and materially improved cash flow and company share price, with strong PM buy-in.
