- Compares the total value of the bill (as calculated by Sigma) against the total value declared on the bill (entered in the Bill this period field).
Electricity Invoiced Vs Calculated
- Compares the total value of the Electricity bill (as calculated by Sigma) against the total value declared on the bill (entered in the Bill this period field).
Gas Invoiced Vs Calculated

Each Validator can be set to allow for a percentage difference

Electricity Invoice Vs Calculated Failure

Invoice cost differs from calculated: FAILED - The name of the Validator

'totalBilledCharge=136.00' - The total charges entered in the Bill this Period field £136.00

'tolerance=1.00' - The percentage tolerance, ie 1%

'upperthreshold=137.36' - The upper threshold (the value in the Billed this period field, plus 1% - ie £136.00 + £1.36 (1%) = £137.36

'MinimumQueryValue=5.00' - The minimum amount the query needs to be (in £s) for the Validator to fail, ie £5

'lowerthreshold=134.64' - The lower threshold (the value in the Invoice cost field, minus 1% - ie £136.00 - £1.36 = 134.64

'totalCharge=126.00' - The amount in the Invoice cost field (the amount Sigma calculates the bill to be), £126.00

'QueryValue=10.00' - The difference between the Bill this period field and Invoice cost field, ie £136.00 - £126.00 = £10.00
