How to Bill a Commercial Tenant for Their Share of Common Area Maintenance Costs
Invoicing a tenant for their proportional share of building operating costs under a triple-net or service charge lease.
| Account Name | Type | Debit ($) | Credit ($) |
|---|---|---|---|
| Accounts Receivable (Tenant — CAM) | Asset (+) | 1,200.00 | - |
| Service Charge / CAM Revenue | Revenue (+) | - | 1,200.00 |
💡 Accountant's Note
Many commercial leases are 'triple net' — tenants pay their proportional share of building operating costs. This is recognized as revenue when billed.
Practitioner & Systems Framework
💻 ERP Architecture
Maintain a service charge account showing all recoverable building operating costs (utilities, cleaning, security, insurance, maintenance) and each tenant's proportional share based on their leased floor area as a percentage of total leasable area. Bill quarterly or annually depending on the lease terms. For estimated service charges, set up a reconciliation at year-end comparing actual costs to estimated charges — rebate excesses or raise deficiency invoices. Present service charge revenue separately from base rental revenue on the income statement.
⚠️ Audit Flags
Auditors verify that service charge calculations are consistent with the lease terms (both the recoverable cost categories and the allocation method). Under IFRS 15, assess whether the landlord is acting as principal (recognizes gross service charge and gross costs) or agent (recognizes only the management margin) — this depends on whether the landlord has control over the services before providing them to the tenant.
