Meet Knock-On,

and see what one change sets in motion.

One change. Every knock-on.

Knock-On is an interactive economics lab for small business owners and learners. Try a change before you make it, and see exactly why the numbers move.

  1. Model your business

    Start from the bakery template in a real spreadsheet, with fictional demo figures or your own. Every result is a formula you can inspect.

  2. Add a shock

    An energy or fuel cost increase, a supplier price rise, or a sales decline. The original baseline stays frozen for comparison.

  3. Compare responses

    Change your price (you enter the sales you expect, nothing is guessed) or switch supplier, and see profit against the baseline.

Ready to see the knock-on?

Open the app, start with the fictional demo bakery, and try your first shock in a couple of minutes.
