Submetering Billing Software: What Owners and Residents Get

What submetering billing software does: imports meter reads, flags leaks, applies rates and bills residents. Compare running it yourself with full service.
What does submetering billing software do?
Submetering billing software collects reads from individual unit meters, checks them for problems like leaks or stopped meters, applies local utility rates, and generates resident statements. For owners and managers, it tracks what the property recovers, watches vacant units, and can export charges to your property management software. For residents, it provides an online portal to review usage history, view statements, and pay online. Modern systems handle this monthly cycle while making sure the total amount billed to residents never exceeds the property's master-meter cost.
Submetering software turns raw meter numbers into monthly resident bills. This guide explains how that process works, what owners and residents see in their portals, and how running software in house compares to hiring a full-service provider.
How submetering software turns meter reads into statements
Turning pulses or radio signals into a utility bill takes several checks. Modern billing systems follow a set workflow each month:
- Capturing wireless reads. Transmitters attached to submeters collect usage numbers and transmit them several times a day to a central on-site collector.
- Auditing raw data. The software scans for problems before calculating bills. It flags zero-read accounts that point to a stopped meter, spikes over normal use, and continuous flow from a plumbing leak.
- Separating common areas. The platform keeps common-area utility use with the owner. Water for the pool, clubhouse, irrigation, and common laundry is not passed through to residents.
- Applying utility rates. The software calculates bills using the property's actual utility rates, including tiered rates, base charges, and local fees.
- Producing resident statements. Statements show starting and ending meter reads, total gallons or kilowatt-hours used, the unit rate, and any allowed fees.
- Syncing with accounting systems. Charge files export directly into your property management software, posting balances to each resident ledger.
What owners and managers see in the platform
Property managers need clear data without sorting through spreadsheets. Dedicated billing platforms give on-site teams direct access to utility operations:
- Continuous leak alerts. MyReads leak detection flags continuous water flow within a day, so maintenance can fix a running toilet before the bill climbs.
- Vacant-unit tracking. The system flags water or power use in empty units, catching unapproved move-ins, running taps, or pipe breaks between leases.
- Recovery reporting. Reports show how much of the master bill came back from residents each month.
- Collections status tracking. Managers can check open balances, track partial payments, and monitor accounts using integrated submetering collections workflows.
- Seven-year records. NES keeps a searchable archive of every unit's bills for seven years.
- Accounting integration. Meter charges export straight to your property management software, so on-site staff never enter utility figures by hand.
What residents get in their portal
When residents understand their utility bills, they spend less time calling the leasing office. A simple resident portal keeps billing clear:
- Itemized statements. Residents see starting reads, ending reads, utility rates, and service dates on each monthly bill.
- Online payment choices. Residents log in from a phone or computer to pay by card, set up bank transfers, or schedule monthly autopay.
- Usage history graphs. Simple charts show month-to-month consumption, so residents can see how water habits affect their balance.
- Paperless billing. Residents can choose email statements instead of paper.
- Customer support access. Residents with questions about a bill or sudden spike can call a bilingual support team directly.
Submetering data: why interval reads matter
Older utility billing relied on someone walking the property once a month with a clipboard. A manager saw one number every thirty days. If a toilet flap failed in unit 204 on the third day of the month, the toilet ran unseen for four weeks. The owner only found out when an expensive municipal bill arrived.
Modern systems use interval reads. Transmitters send numbers several times a day. Managers can see how water, gas, or electricity moves through a building throughout the week.
Interval data uncovers maintenance issues quickly:
- Plumbing repairs. A running toilet shows continuous flow on the portal within a day instead of hiding until the monthly utility bill arrives.
- Equipment problems. Sudden overnight electric spikes help identify water heaters or circulation pumps that are failing or cycling wrong.
- Irrigation breaks. Timed usage logs show when sprinklers run during rainstorms or run long after scheduled shutoff times.
The basic idea of submetering is that people use less of what they pay for. When residents pay for their own water, water use typically drops 15 to 30 percent. At one 337-unit community, NES added meters as leases renewed, so for a while both setups ran side by side. The 168 submetered units averaged 3,868 gallons per unit per month, 34% less than the 5,846 gallons used by the 169 units not yet metered. Their average bill was $54.22 a month against $84.72, 36% lower, or about $30 per unit. Across all 337 units, that gap is worth roughly $123,000 a year.
Software only vs. a full-service provider
Some owners prefer to buy software and manage every step themselves. Others hire a full-service provider to handle equipment installation, reads, billing, customer calls, and rate rules.
Meter installation
- Software you run
- Handled by your own team or outside plumbers
- Full-service provider
- Installed by company technicians or equipment shipped to your plumber
Data audits
- Software you run
- On-site staff must diagnose offline transmitters
- Full-service provider
- Monitored and validated by the provider
Rate compliance
- Software you run
- On-site team must track local utility rules
- Full-service provider
- Compliance specialists check state, county, and city rules
Statement delivery
- Software you run
- In-house staff prints or emails statements
- Full-service provider
- Provider sends statements by mail or electronically
Payment processing
- Software you run
- Office staff collects checks and tracks fees
- Full-service provider
- Provider processes autopay, cards, and online payments
Resident questions
- Software you run
- Office staff answers billing disputes
- Full-service provider
- In-house bilingual customer service team takes calls
Collections
- Software you run
- Property managers pursue late balances
- Full-service provider
- Provider tracks unpaid accounts systematically
Hardware warranties
- Software you run
- Owner coordinates repairs with manufacturers
- Full-service provider
- Provider supplies nonproprietary meters backed by warranty
Running software yourself gives you direct oversight, but monthly billing takes real work from leasing agents. If your team cannot take on daily meter audits, resident phone calls, and local utility regulations, a full-service setup saves staff time.
Questions to ask before choosing submetering software
Choosing billing software or a service partner shapes your property operations for years. Ask these questions before signing an agreement:
- How often do reads come in? If the system updates once a month instead of daily, it cannot warn you about running toilets or hidden leaks.
- Who audits the meter reads? Find out whether your office staff must investigate dead meters, or if the provider's team handles read validation.
- How are resident disputes handled? Ask if your staff takes calls about high water use, or if the provider provides an in-house customer service line.
- Can you export your data? Make sure you can export historical billing and consumption files into CSV or Excel files whenever you need them.
- Who checks local utility regulations? Rules change across state, county, and city lines. Ask if the vendor tracks utility rules for your property's exact address.
- Do you own the equipment? Choose nonproprietary meters so you are never locked into one software company if your needs change later.
