A whole year of invoices, validated, free.

This is not a slideshow. Send us a year of your supplier invoices — starting with the one you are least sure about — and we will show you what an independent rebuild of them says.

  1. 01

    A short conversation

    Twenty minutes on your estate, your suppliers and what you check today.

  2. 02

    A year of your own invoices

    Real invoices are the whole test. We rebuild them and go through what agrees and what does not, line by line.

  3. 03

    A reply within one working day

    You will hear back from a person, not a queue. If the invoices are right, we say so; that is a useful thing to know too.

  4. 04

    Your invoices stay yours

    An invoice you send is used for that rebuild and nothing else, is not shared with anyone outside Simplest Energy, and is deleted on request.

Or reach us directly.

We use this to reply to you, and nothing else.
