The Gap Nobody Local Has Filled
Thousands of Nigerian estates, serviced apartment blocks, malls, markets, campuses and mini-grids resell electricity and water to their residents and tenants. Almost all of them run it the same way: prepaid meters installed by whoever supplied them, vending done through the meter manufacturer's own software or a WhatsApp message to an operator, cash collected at the estate office, and a monthly argument about whether the numbers add up.
The metering hardware and the vending systems behind it come overwhelmingly from South African vendors, because the Standard Transfer Specification ecosystem grew up there. Those systems work. What they do not do is the rest of an estate's operation — the diesel recovery, the service charge, the arrears, the tenant ledger, the facility management — and they are not built or supported locally.
The result is a genuine gap. We have not found a single Nigerian software company with a dedicated offering here, while the demand is visible in every gated estate in Lekki, Abuja and Port Harcourt.
The commercial problem in one sentence: most estates cannot tell you, on any given day, how much energy they bought, how much they vended, how much cash they hold, and how much residents owe — which is exactly why estate utility accounts are where money disappears.
Token Vending, Done Properly
STS token generation
Twenty-digit Standard Transfer Specification tokens generated against each meter, with correct handling of the meter's key revision and the token identifier rollover that catches out systems built without understanding it. We integrate with your meter vendor's vending interface or their approved third-party gateway, because token generation must be authorised through the correct key management chain.
Idempotent and recoverable
A resident who pays once gets one token, even if the network drops mid-transaction and they retry three times. Tokens are stored against the payment, so a lost SMS is a re-send rather than a second charge. Failed vends are refunded automatically rather than becoming an office dispute. This sounds obvious and it is where most homegrown systems fail.
How residents actually buy
A resident app and web page, USSD for anyone without data, a WhatsApp bot, bank transfer to a dedicated virtual account per unit, and cash at the estate office recorded against the same ledger. Token delivered by SMS and in-app within seconds. Low-balance alerts before the power goes off, which is the feature residents notice most.
Reconciliation that closes daily
Energy purchased from the disco or generated on site, against energy vended, against cash received, against bank balances. Losses — technical, commercial and plain theft — quantified per feeder and per block rather than absorbed into the service charge. A daily close with any break flagged to the facility manager the same morning.
The Rest of What an Estate Actually Bills For
Electricity is the visible part. The disputes usually come from everything around it.
Diesel and generator cost recovery
The hardest thing to bill fairly in Nigeria. Generator run hours and fuel consumed, allocated across units by metered consumption during generator periods rather than by flat share, with the fuel price of the day applied and the calculation visible to residents. Estates that show the working stop having the argument.
Hybrid supply accounting
Grid, generator, solar and battery each with a different cost per kilowatt-hour. Consumption attributed to whichever source was supplying at the time, so the tariff reflects reality and residents can see why the rate moved. Essential for estates that have added solar and want to demonstrate the saving.
Service charge and levies
Periodic service charge per unit by size or category, special levies for capital projects, security and waste fees, with invoicing, part-payment, ageing and statements. Debtor lists the facility manager and the residents' association can both see.
Arrears and enforcement
Escalating reminders, restriction rules where the estate's own constitution permits them, payment plans for residents in genuine difficulty, and a clear audit trail behind every restriction so enforcement is defensible rather than personal.
Water, waste and other utilities
Prepaid or postpaid water on the same ledger, borehole pumping costs recovered, waste collection fees, and any other recoverable the estate operates.
Who We Build This For
Estates and facility managers
Gated estates, serviced apartments and residents' associations reselling power and water to occupants, who need the billing, the service charge and the facility operations on one ledger.
Sub-metering operators
Businesses that install and manage meters across many estates as a service. You need multi-site tenancy, per-site tariffs and settlement, and a consolidated view across the portfolio.
IPPs, mini-grids and campuses
Independent power producers, NERC-permitted mini-grid operators, universities and industrial parks distributing to connected customers, with tariff classes and regulatory reporting.
A regulatory note worth taking seriously. Reselling electricity is not unregulated. Depending on your arrangement, NERC rules on embedded generation, distribution, sub-metering and tariffs may apply, as may the rules of the newer state electricity regulators, and there are limits on what can be charged above the cost of supply. Musskart builds software and holds no energy licence or permit. The permits, the tariff approvals and the compliance are yours; we build the system that makes operating under them practical, including the reporting.
Cost, Timeline and Where to Begin
Single estate
₦4,000,000 – ₦7,000,000
Units and residents, meter register, token vending with your meter vendor's gateway, resident app and USSD, payments, service charge, arrears, daily reconciliation and the facility manager's dashboard. Eight to twelve weeks.
Estate + facilities
₦7,000,000 – ₦12,000,000
Adds diesel and hybrid cost recovery, maintenance and work orders, visitor and access management, community notices, and the residents' association reporting pack. Three to five months.
Multi-site operator
₦12,000,000 – ₦18,000,000
Many estates on one platform with per-site tariffs, settlement to each site owner, agent and technician apps, portfolio analytics and loss reporting, and a white-label resident app per site. Five to eight months.
Start with vending and reconciliation. Eight to twelve weeks, and it is the piece that pays for itself, because the moment energy purchased, energy vended and cash received are reconciled daily, the leakage becomes visible and usually stops. Add the service charge and facilities modules afterwards, once residents trust the electricity numbers — trying to reform everything at once in an estate with an active residents' association is a political mistake as much as a technical one.
The first technical question we will ask is which meters you have and whose vending system they sit behind, because that determines the integration path and it is the one thing that can hold a project up. Have your meter make, model and vendor contact ready.
