Case Study: Tamarack Grove Engineering achieves 58% DSO reduction with Unanet AR Automation

Better efficiency enables faster growth: Tamarack Grove reduces DSO by 58% with Unanet AR Automation

Tamarack Grove Engineering, a Boise-based structural engineering firm founded in 2007, was managing up to 300 projects with spreadsheets and manual invoicing. Lacking a formal accounts receivable process, the firm struggled with errors, slow billing and a days sales outstanding (DSO) of roughly 60–65 days, which constrained cash flow and growth.

In 2018 Tamarack Grove implemented Unanet AR Automation — adding automated invoicing, a centralized AR dashboard, Stripe integration and flexible ACH/credit card payments — to streamline collections and provide real-time financial visibility. The changes shortened billing cycles, boosted cash reserves, cut DSO to 38 days, reduced write-offs, and freed the team to focus on growth, including a move to a facility three times larger.
