What are the best water utility billing software options for improving billing and customer service?

Here are some of the best water utility billing software options to improve billing accuracy, customer service, meter-to-cash workflows, self-service, and collections. The “best” choice depends on utility size, regulatory needs, and whether you want a full CIS/ERP platform or a billing-only solution.

Top options to consider

1) Oracle Utilities Customer Care and Billing (CC&B)

Best for: Large utilities, complex billing, enterprise-scale operations
Strengths:

• Very strong for end-to-end customer information and billing
• Handles complex rate structures, service orders, and payment processing
• Good integration with meter data, call centers, and field operations
• Scales well for large public utilities and municipalities

Watch for: Implementation can be long and costly, and it often requires experienced consultants.

2) SAP Utilities / IS-U

Best for: Large, enterprise utilities already using SAP
Strengths:

• Robust customer billing and revenue management
• Strong integration with finance and asset systems
• Suitable for utilities with complex accounting and enterprise reporting needs

Watch for: Can be expensive and complex to deploy; best fit if you’re already in the SAP ecosystem.

3) Harris Advanced Utility Systems (CIS / billing solutions)

Best for: Municipal and mid-sized utilities
Strengths:

• Built specifically for utility billing and customer service
• Good for water, sewer, and multi-utility billing
• Often easier to adopt than the largest enterprise platforms
• Helpful customer service and billing workflows

Watch for: Product fit varies by module and deployment model; evaluate implementation support carefully.

4) Tyler Technologies utility billing / ERP solutions

Best for: Cities and public-sector utilities
Strengths:

• Good fit for municipal operations and government finance
• Integrates with broader public-sector ERP/workflow needs
• Supports billing, payments, and customer records

Watch for: May be stronger as part of a broader government software stack than as a standalone best-of-breed billing tool.

5) CXU / Springbrook

Best for: Small to mid-sized municipalities
Strengths:

• User-friendly for local governments
• Good billing, payment, and service management features
• Often easier to implement than enterprise systems

Watch for: May not be ideal for highly complex utility environments or very large customer bases.

6) AquaHawk / leak detection plus customer engagement platforms

Best for: Improving customer service and reducing complaints, not core CIS replacement
Strengths:

• Alerts customers to unusual usage or leaks
• Improves customer communication and conservation
• Can reduce high-bill complaints by catching anomalies early

Watch for: Usually complements existing billing systems rather than replacing them.

---

7) Advanced Metering Infrastructure (AMI) integrated billing platforms

Examples vary by vendor, but if your priority is better billing accuracy and fewer estimated reads, choose software that integrates tightly with AMI/MDMS systems.
Best for: Utilities modernizing meter-to-cash
Strengths:

• Better consumption data, fewer estimated bills
• Faster issue detection
• Enables self-service usage insights

Watch for: The value depends heavily on meter infrastructure and integration quality.
