What's the best utility billing software for billing residential and commercial water customers?

The “best” utility billing software for residential + commercial water customers depends a lot on your size, workflow, and whether you need things like meter integration, AMI/AMR, complex rate structures, work orders, online payments, and tax handling.

That said, these are commonly considered strong options for water utilities:

If you’re a smaller utility or district

Look closely at:

• Springbrook

• N. Harris

These are often easier to adopt and are well-suited to mixed residential/commercial billing.

If you’re a larger or more complex utility

Look at:

• Tyler Technologies

To give you a real “best” recommendation

Tell me:

1. Approximate number of customers
2. Residential vs commercial mix
3. Need for AMI/AMR meter integration?
4. Do you also bill sewer/trash?
5. Cloud or on-prem preference?
6. Budget range

And I can narrow it down to the best 2–3 options for your utility.
