Case Study: Sonnedix achieves centralized global legal spend visibility and cost control with Brightflag

How Sonnedix Built a Sustainable Strategy for Controlling Legal Spend

Sonnedix, a global solar independent power producer preparing to scale its operating capacity, faced a lack of clarity and consistency in legal billing that threatened both cost control and team productivity. Needing an easy-to-adopt solution that would work with dozens of outside firms and provide stronger analytics, Sonnedix selected Brightflag’s legal spend management platform — an AI-powered invoice review and centralized billing portal designed for in-house legal teams.

Brightflag rolled out a single submission portal and automated review workflows, giving Sonnedix real-time visibility into global legal spend, eliminating unapproved invoices, and reducing time spent on invoice review. The platform helped Sonnedix consolidate its law firm panel from more than 60 providers to fewer than 30, support data-driven negotiations (including fixed-fee arrangements), and produce measurable operational gains — for July 2020–June 2021 Sonnedix reported 93% of matters starting with a budget, 93% featuring AFAs, and an average 5.2 days from invoice submission to approval — delivering clear cost controls and predictable budgeting with Brightflag.
