Modern utilities are facing a “billing bottleneck.” As complex rates driven by EVs, DERs, and time-of-use structures outpace the capabilities of legacy Customer Information Systems (CIS), utilities are often forced into risky, multi-million dollar system overhauls or expensive manual workarounds.

This Guidehouse Insights white paper explores how a modular, add-on billing engine allows utilities to decouple complex rate intelligence from their core CIS. By externalizing rate complexity, utilities can leave their legacy systems stable while deploying innovative rates in months rather than years—all at a fraction of the cost.

 Key Takeaways:

• Massive Capital Savings: Avoid or defer $25M – $490M+ in capital expenditures compared to a full CIS modernization.
• Rapid Time-to-Market: Deploy new rates and pilots in just 3–6 months, which is roughly 75–85% faster than traditional CIS customization.
• Reduced Operational Cost: Lower the marginal cost of implementing new rates by 80–95% by moving from custom coding to simple configuration.
• Mitigated Risk: Minimize billing defects and regulatory disallowance by moving “off-system” calculations (like spreadsheets) into a scalable, auditable platform.
• Enhanced Customer Experience: Deliver “bill-grade” transparency and personalized coaching that reduces call center volume and improves regulatory standing.
