  </Step>

  <Step title="For combined discounts">
    For multiple discount levels, calculate the total combined discount and enter it. Depending on how the discounts are applied you need to calculate them differently.

    You can find a spreadsheet tool to help you calculate the combined discount [here](https://docs.google.com/spreadsheets/d/186BCs-W_IrTwNoSy5CIm7iN-9fu6deYzAzBZmOraw1w/edit?gid=0#gid=0).

### Calculation Examples for Discounts

<Accordion title="Examples for Discount Calculations">
  1. **Combined discount with different discount levels**:
     * Example: 4% cash discount and 1.5% invoice discount plus 3% central purchasing discount
     * Formula: `(1-((1-0.04)\*(1-(0.0015+0.03))) = 5.09%`
  2. **Sum discount at the same level**:
     * Example: 2% logistics discount and 1.5% invoice discount, which apply to the same level (initial price)
     * Formula: `0.02+0.015 = 3.5%`
</Accordion>

<Info>
  The correct calculation and representation of discounts is important for the acceptance of invoices by your trading partners.
