At a glance

Where Minol fits

Minol USA, powered by Brunata and based in Addison, Texas, belongs to the Minol-ZENNER Group, which acquired Brunata International in 2018, per Minol USA. Minol runs four solution areas: meter installation and service, utility expense management, a utility billing program, and strategic solutions.

The billing program is a turnkey back office with bill generation, a U.S.-based call center, payment processing, delinquency management, and the MinolDirect resident portal. On the multifamily side, Minol handles submetered water, electric, and gas, plus RUBS allocations, and its meter work includes AMI integration with any system.

Minol also serves military, affordable, and student housing and municipalities. The group describes itself as one of the largest water meter manufacturers, with a global team that services more than 30 million utility meters, and its sister company ZENNER USA makes water and heat meters.

Minol is the right answer when you want a hardware-backed, turnkey provider, particularly for military, affordable, or municipal programs. Ask Minol for pricing and terms in writing.

Why operators choose Billee as a Minol alternative

Billee runs submetering as a managed service: modern software, a named account team, and hardware support under one roof. Billee is built specifically for utility billing and management, not as a module inside a broader PMS or payments suite.

Submetering from the meter to the bill

Billee's hardware and maintenance support covers sourcing, installation coordination, and ongoing calibration for submetering infrastructure, and the team dispatches repairs when a meter fails. Billee's meter monitoring pulls AMR data from major hardware vendors into one portfolio view, so properties on different meter brands share one picture of meter health. AMI properties give monitoring even more frequent data.

Every read then passes through a validate, estimate, edit process with a logged audit trail before it becomes a bill, as Billee's guide to how submeter data is collected and reported explains.

Why submetering pays

Submetering bills residents for measured use, and the evidence favors it. An EPA-sponsored study found that submetering cut apartment water use by 15.3%. Billee's data puts recovery at 85–95% for submetered properties and 70–85% for RUBS. Water submeters typically cost $300 to $1,500 per unit to install, and Billee says most operators recover that within 8 to 14 months, per Billee's submetering guide.

A named team that does the work

Every Billee customer has a named primary account manager and specialists for billing exceptions, vendor management, Vacant Cost Recovery, and reporting. Team-handled actions follow a 1–2 business-day standard, per Billee's service commitments. Meter alerts route to the same team instead of a generic queue, and the team dispatches repairs, contacts residents, or escalates to the owner.

Vacant Cost Recovery that ends in action

Billee's Vacant Cost Recovery engine watches meter activity against PMS occupancy data. When a unit marked vacant keeps drawing usage past a set threshold, the exception goes to a named team member who acts on it.

A billing cycle with a review step

Each month, Billee generates a preliminary billing report. Your billing administrator reviews it in the Billee portal alongside Biller Highlights, which are the billing team's notes on exceptions. Charges post to the PMS resident ledger only after approval, and e-bills follow.

The dashboard tracks recovery for the portfolio. Billee treats 80–95% effective recovery as great performance and anything below 80% as a signal to check vacant units, hardware, or allocation. An activity log records every billing action.

Vendors, ESG, and compliance on the same platform

Billee also runs utility vendor management with native AP integration, ESG reporting drawn from the same utility data, and regulatory and compliance support that pairs a billing methodology audit with access to legal support.

Yardi, RealPage, and Entrata, live in 45 days

Billee works with Yardi, RealPage, and Entrata, with the PMS staying the system of record. Billee's standard implementation takes 45 days and covers PMS integration, historical data migration, vendor transitions, a methodology audit, and training, led by a named project manager.

Billee's guide to switching providers recommends starting with a billing audit instead of a data migration, and moving property by property so two providers never bill the same units at once.

Billee and Minol side by side

Who Billee is not for

Billee fits roughly 500 units and up. By Billee's own guidance, a dedicated team is more than the job needs below about 300 units. Operators of privatized military housing or municipal water programs should look at Minol, and operators who want billing and meter manufacturing from one corporate group should ask Minol about ZENNER.

Five other alternatives to consider

Guardian Water & Power

Guardian Water & Power, founded in 1983, is a full-service water submetering and utility billing company that handles submeter system design, installation, data acquisition, billing, collections, and utility management. It serves apartments, condominiums, marinas, military bases, manufactured housing, and commercial properties. It fits operators who want a long-standing water-submetering specialist. Billee adds vendor management, meter monitoring, and ESG reporting on the same platform.

National Exemption Service

National Exemption Service (NES) has managed utilities for multifamily owners since 1968 and serves properties in more than 43 states. NES says its own technicians install the meters, readings land in its platform daily, and a bilingual team runs resident billing and support. It also offers utility expense management, where NES pays the property's utility bills and bills residents proportionately. It fits operators who want in-house installation and billing from a long-standing specialist.

Anchor Utility (formerly Banyan Utility)

Anchor Utility rebranded from Banyan Utility on October 27, 2025 and has served multifamily operators since 2007, with a 65-point bill validation process. Anchor handles submetering design, installation, meter reading, and billing for properties of 20 or more units. It fits operators who want a focused specialist. Billee offers a similar service-led model for larger portfolios.

Synergy Utility Billing

Synergy Utility Billing LLC, founded in 2007, offers submetering, RUBS billing, submeter installation, billing and collection, analytics, and system design consulting. It serves properties from duplexes to large multifamily, plus HOAs, mobile home parks, and municipal water districts. It fits operators who want one boutique firm to design a submetering system and run billing. It is not Synergy, Conservice's expense management product.

Conservice

Conservice calls itself the nation's largest utility management and billing company. It fits very large portfolios. Scale cuts both ways, so ask which named people will run your portfolio. Billee's Conservice comparison goes deeper.

How to choose a Minol alternative

Choosing among Minol alternatives comes down to six questions.

1. Who selects, installs, and services your meters? Ask every vendor whether you can choose your meter hardware and who owns calibration and repairs.
2. AMR or AMI? AMR meters send periodic cumulative reads, while AMI meters send interval data. Confirm which your properties have and how each vendor monitors them.
3. Which property types do you manage? Multifamily-only portfolios fit most vendors here. Military housing narrows the field to Minol and Guardian, and municipal billing points to Minol or Synergy.
4. Is your PMS on the vendor's list? Get PMS support confirmed in writing, since each vendor publishes a different list.
5. Who works billing exceptions, and how fast? Ask each vendor to name the person and the response time. Billee names a primary account manager and works to a 1–2 business-day standard.
6. Who answers resident calls and handles payments? Minol runs a U.S.-based call center and payment processing, and NES uses a bilingual billing team. Ask every vendor how resident support, payments, and fees are handled.
