Aazly
Built for water districts- Best for:
- Districts and associations that want both a modern admin back office and a branded ratepayer portal.
Aazly pairs an admin portal, where teams configure billing, onboard customers, and oversee payments, with a branded customer portal on the district's own subdomain, where ratepayers pay bills, set autopay, and view usage 24/7. Payments are PCI-compliant across card, ACH, check, and cash, with funds going straight to the district's account. The strongest fit if you want a modern, branded online experience rather than a paper-first workflow.
WUBS (Water Utility Billing Software)
- Best for:
- Single-clerk rural districts that read meters in-house.
- Pricing:
- Per-service monthly + setup (source)
WUBS connects field meter reading to office billing with offline GPS readings, photo evidence, tiered rates, oldest-first payment application, and role-based portals, including a self-service board-member view. Month-to-month after a six-month intro. The closest like-for-like to Online Water Bill's in-house meter-reading strength.
The Utility Biller
- Best for:
- The smallest systems that want transparent pricing and a free tier.
A full CIS with meter management, flexible rates, Stripe-powered payments, collections, and a branded self-service portal. The free plan (up to 500 accounts) makes it the most accessible option; paid tiers remove the customer convenience fee and add collections automation and field ops.
Muni-Link
- Best for:
- Water/sewer districts wanting an automated meter-to-cash CIS.
Muni-Link automates invoicing, notices, service orders, and payment posting, with AMI/AMR imports, complex rate support, integrated payments, and a customer portal. Its billing is CASS-certified to cut undeliverable mail, and it integrates with GIS, accounting, and meter software.

- Mutual water companies billing shareholders.
- Pricing:
- One-time setup + monthly (source)
Spigot handles smart billing, payment tracking, shareholder and service-connection records, and usage analytics, plus a field iOS app with camera OCR, GPS, and offline mode. Flat pricing with unlimited accounts and meter reads suits growing companies that dislike module upsells.
