Every site. Every meter.
Single source of truth.

Single source of truth. How?

Your energy. From every angle.

Everything in the platform

What stops being your problem.

Two kinds of organisation.

One runs an estate and answers for it. The other answers for somebody else’s. The engine is the same; what changes is whose queue the bills sit in.

If you run the estate

Your estate.
Your answers.

Finance wants the variance, sustainability wants the number, and the site wants to know why its bill went up. The answers stop being something you reconstruct.

For estate energy managers
If you validate for clients

Their bills.
One standard.

Every client’s invoices rebuilt from the published rates, in one queue, with the calculation attached to the query and the run kept as evidence.

For bureaux and consultants

A lot of different desks.

  • Energy managers
  • Energy and finance analysts
  • Site and facilities managers
  • Sustainability leads
  • Procurement
  • Finance business partners
  • Bureau and consultancy teams

12 permissions over 4 base roles, plus custom roles and per-organisation overrides, so the site manager who needs one report does not also get the contract record.

Finance asks a different question

You pay nothing until it is running.

Every bill answers six questions.
In the order one failure causes the next.

Is this bill even yours?

Meter point, supplier and account are matched to a site and a contract you hold. A bill for a meter you left two years ago fails here rather than quietly reconciling.

Ten symptoms never bury one fixable cause: the earliest failing check is tagged as the reason, and everything downstream of it as a consequence.

Everything it rebuilds

Commodity is the easy half.

The rest changes by region, meter, settlement period and charging year. Each of these is modelled from its own published source, for power, gas and water alike.

Two adjustments, not charge types

Line-loss factors
Gross the metered volume up for the charges levied at the grid supply point: transmission, balancing and AAHEDC.
EII exemption and CCA relief
Reduce the levies, and the Climate Change Levy in turn.
A weekday, priced the way the network actually prices it

Published LPN time bands. The demand shown is an illustrative weekday shape.

While you are not there

Overnight, without anyone logging in.

Every night
Imbalance prices and gas calorific values are fetched and stored, so a bill that arrives tomorrow is checked against what the market actually published today.
When a rate settles
A bill priced from a draft figure is re-validated the day the final one lands, and the part that was held is either cleared or becomes a query.
When an invoice does not arrive
A supply that should have been billed and was not is noticed, and the chase to the supplier is drafted against the meter and the date it was expected.
On its schedule
The reports somebody asked for are built and delivered, to the people who still work there when the run happens.

None of it needs a person to start it, and none of it is a reason to employ one.

checked the working.

Agrees
The rebuilt figure matches the invoice.
Differs
It does not match, and the reason is named.
Held open
It cannot be settled yet, so it is not passed.
