Invoicing services
Your energy invoices are costing you more than they should
Every month, errors slip through. Costs stay invisible. Tenant billing runs on spreadsheets. EG EnerKey fixes that for electricity, heating, and water invoices, automatically.
What happens to most energy invoices today
Too many approvals
Accounts payable, property managers, supervisors. Each hand-off adds delay.
Nobody trusts the cost data
Finance enters numbers by hand. Budget vs. actual is always behind.
Tenant billing runs on memory
Someone updates a spreadsheet each month. Numbers drift. Disputes follow.
We can handle your entire energy invoice flow
You get one flow for electricity, heating, and water. Every invoice linked to consumption data. Deviations flagged early. Invoice history and cost allocation visible in EG EnerKey. Tenant billing data delivered directly in your agreed format. Your tenants know exactly what they are paying for.
Manually
Invoices checked manually, if at all
Cost data keyed in by hand, always lagging
Accounting details added manually per invoice
Tenant billing based on estimates and spreadsheets
Errors caught after payment (if ever)
With EG EnerKey
Every invoice validated against metered data and tariff records
Actual costs flow into reporting automatically, budget vs. actual always current
Invoices arrive correctly coded and payment-ready
Costs allocated by actual consumption, billing data delivered monthly
Errors flagged before payment, supplier contact handled by EG EnerKey
Three steps. You do the first one. We handle the rest.
Your electricity, heating, and water suppliers send invoices to us instead of directly to you. We set this up during onboarding. Your existing systems stay in place.
Each invoice is checked against metered consumption and tariff data. Accounting details are added automatically. Cost data flows into EG EnerKey reporting. If something is wrong, our service team contacts the supplier directly.
Validated, coded, and sent to your finance system without delay. If you have multi-tenant properties, tenant billing data is generated and delivered automatically in your preferred format.

Start where it makes sense for you
You do not need to buy the full pipeline on day one. Most customers start with cost reporting and scale up as they see results.
Start with cost reporting
Get actual energy costs into your reporting without manual data entry. Invoices pass through EG EnerKey briefly, cost data is captured, and the invoice continues to your finance system. Budget vs. actual is always current.
This is the natural starting point. Upgrade to full validation when you are ready.
Best for: Organisations that handle supplier disputes directly but need actual cost data in reporting.
Add invoice validation
Everything in cost reporting, plus consumption cross-checked against metered data and prices verified against tariff records. Accounting details added automatically. Invoices arrive at your finance system correctly coded and payment-ready.
Best for: Large portfolios where accuracy and payment efficiency matter.
Extend to tenant billing
For multi-tenant properties where one invoice covers the entire building. EG EnerKey allocates costs across tenants based on actual metered consumption and delivers billing data in PDF, CSV, or TEAPPS XML.
Best for: Multi-tenant properties: shopping centres, office buildings, mixed-use facilities.
