find errors in your spreadsheet models

ExcelCheck is a review service for your Excel models and spreadsheets.   Whatever size of spreadsheet we check it for errors.

What does ExcelCheck do?

For the ExcelCheck service, we:

  • check the logical and arithmetical integrity of your spreadsheet model
  • ask you to define your commercial objectives and question you to justify your approach to answering these
  • allow you to look at all your inputs, calculations and outputs again in total clarity so you can re-consider the logical steps and the approach

Furthermore, to make sure the service is effective, pragmatic and value-for-money:

  • only the core elements that we truly believe are most beneficial to you are drawn from the formal professional model audit process:
    • logical and arithmetical integrity
    • commercial top-down review
  • in order to cut down on redundant logic, we require you to answer a series of up front questions about your spreadsheet:
    • which are the important results you wish to see checked?
    • can all the rest be treated as noise? (and therefore ignored)

To do this, ExcelCheck

  • leaves out the very expensive elements that we believe are unnecessary for the vast majority of spreadsheet model owners, including:
    • full accounting review
    • full tax review
    • sensitivities review
    • document review
    • opinion letter (insurance policy)
  • uses the shadow modelling technique by building a parallel model and investigating all the differences to your original model
  • delivers to you the parallel model as a new, fully-functioning model with the same corrected results of your original model

How much does ExcelCheck cost, and how long does it take?

ExcelCheck is charged on an ‘hourly’ basis, except it can be discounted because of the clear specification.

It depends on the size of your spreadsheet and the amount of repetition/duplication – we have the experience and software to work that out.

It can take from a few hours to longer, depending on some very explainable technical factors – like duplication, the number of original formulae and the complexity of the original formulae.
