Real-time billing engine

Real-time billing engine

Event driven and utilising the power of cloud technology, the billing engine calculates charges based on the latest available information as and when it is received, meaning no more batch processing ahead of a major bill run – from single-site fixed billing through to bespoke flex & pass-through products.

Ofgem compliant

Make a statement

All our statements are Ofgem compliant across all energy products, from fixed NHH through to HH Flex & Pass-through. For complex group hierarchies, ENSEK’s billing engine supports the ability to consolidate multiple MPANs and sites up to a single invoice with a bespoke bill format.
