Case Study: CallisonRTKL achieves faster billing and a 14–15% reduction in 60+ day receivables with Elevia Software

Global A&E Giant Achieves Accounting Trifecta With 3 Elevia Software Products

CallisonRTKL, a global architecture and design firm, faced a time‑consuming, paper‑heavy billing and collections process—reviewing about 500 client invoices a month and carrying significant receivables past 60 days. To streamline billing, improve sustainability and automate collections while integrating with their Deltek Vision ERP, CallisonRTKL deployed Elevia Software solutions, beginning with Elevia Electronic Invoicing and later adding Elevia A/R Management & Collections (and subsequently purchasing Elevia Payables Approval & Tracking).

Elevia Software replaced paper reviews with electronic draft invoices, approver notifications and integrated supporting documentation, cutting the invoice review cycle by three days and giving project managers real‑time visibility into billing metrics. Using Elevia A/R Management & Collections’ automated, tiered collections and dashboard, CallisonRTKL reduced receivables over 60 days by about 14 percentage points, boosting cash flow—and expects similar payables improvements after implementing Elevia’s payables product.
