Managing agents are responsible for administering energy on behalf of landlord clients, often across multiple buildings and with multiple suppliers. Maintaining reliable billing visibility across a managed portfolio, when invoices arrive at different times and in different formats from different suppliers, is one of the more demanding administrative tasks in property management.
The billing visibility problem in commercial property management
Billing visibility refers to the ability to see, at any given time, what energy costs have been incurred, what invoices have been received, what has been checked and what is outstanding. For a managing agent with a single building and a single supplier, this is straightforward. For a managing agent with a portfolio of ten or more buildings, each served by different suppliers under different contracts, it becomes a significant administrative challenge.
The problem is compounded by the way commercial energy invoices arrive. Some suppliers issue invoices monthly, some quarterly. Some send them by email, some by post, some through dedicated supplier portals. Some suppliers invoice promptly at period end; others issue invoices weeks late, meaning that a complete picture of a month's energy costs may not be available until well into the following month.
Without a systematic approach to collecting, recording and checking invoices, gaps will occur. Some invoices will be missed, others paid without checking, and the cumulative effect of unverified billing across a portfolio creates both financial risk and a poor evidence base for service charge reconciliations.
What invoice checking involves
Invoice checking is the process of verifying that each invoice issued by a supplier is correct before it is approved for payment. At minimum, this involves confirming that the invoiced unit rate matches the contracted rate, that the standing charge is as agreed, that the invoiced consumption is consistent with the available meter data, and that the invoice covers the correct period.
In practice, a thorough check also considers whether the invoice is the first for this supply point in the period or whether a previous invoice has already been issued, whether any credits from previous disputes have been applied, and whether the invoice basis is an actual read or an estimate. Estimated reads should be checked against any available actual read data and queried where they appear significantly over- or understated.
The outcome of the check should be documented. A record of which invoices have been checked, what the outcome of the check was and any issues identified creates an audit trail that is valuable both for internal quality purposes and for resolving any subsequent disputes with suppliers or queries from landlord clients.
A billing error that goes unchallenged for one period is a discrepancy. The same error continuing for six periods is a dispute, and disputes take significantly more effort to resolve than early-identified discrepancies.
Rate verification and contracted terms
Rate verification is the element of invoice checking most likely to identify and recover money for landlord clients. Unit rates in commercial energy contracts can vary significantly, and it is not uncommon for suppliers to apply incorrect rates, particularly at contract renewals or following a contract re-sign where the new rates have not been updated promptly in the supplier's billing system.
Verifying rates requires holding a copy of the supply contract for each supply point, with the contracted unit rate and standing charge recorded in a form that can be quickly referenced when invoices are received. For portfolios with many supply points and different contract end dates, maintaining this reference information in an organised record rather than in individual document files reduces the time required for each check.
Where a rate discrepancy is identified, it should be raised with the supplier promptly and in writing, with the contracted rate and the invoiced rate clearly stated alongside the invoice reference and the period affected. Early, documented escalation is the most effective way to prevent a single invoicing error from repeating across multiple periods.
How billing disputes arise and how to document them
Billing disputes typically begin as single-period discrepancies that are either not identified at the time or identified but not formally raised. When the same error persists across multiple periods, the cumulative overbilling becomes a dispute rather than a correction, and the process of recovering it becomes more complex.
Effective dispute documentation sets out the contracted rate, the invoiced rate, the difference per unit, the invoiced consumption for each affected period and the cumulative total overbilled. Presented clearly and with invoice references attached, this gives the supplier a complete, structured case that can be processed within their own escalation hierarchy. A poorly documented dispute without clear figures is far easier for a supplier to delay or dismiss.
Keeping a log of all correspondence related to a dispute, including dates, contact names and the content of any phone conversations, is important if the dispute needs to be escalated beyond the supplier's front-line customer service team. Regulatory bodies and ombudsman schemes may require evidence of reasonable escalation attempts before they will consider a complaint.
Building a reliable billing process for managed portfolios
A reliable billing process for a managed portfolio begins with a clear picture of what invoices are expected, from which suppliers, at what frequency and covering which supply points. This invoice schedule, cross-referenced against the MPAN register, forms the basis of a simple checking system: when an invoice arrives, it is matched against the schedule, checked against the contracted rate and logged.
Centralising invoice receipt, so that all supplier invoices arrive to a single managed inbox or collection point rather than to different team members, reduces the risk of invoices being missed or processed without checking. Linking invoice filing to the client portal means that landlord clients can access their invoices without needing to request them from the managing agent's team.
Where energy management is handled by a specialist third party rather than in-house, the billing administration process should be defined clearly as part of the service, with an agreed turnaround for invoice checking, a defined escalation process for disputes and regular reporting to the managing agent and landlord client on the status of invoices and any outstanding issues.
