In practice, if the passenger uses a promo code, you will see it on the end of journey screen.
You will only have to collect part of the fare.
Don't worry, Heetch will of course pay you the difference in the next transfer (€5 in the example above).
You can find this information in the income section of the application, as well as in the Monday recap email.
On Heetch there are many cash rides. It's a possibility loved by passengers and drivers, and we want to build on that.
By allowing passengers who order in cash to use coupon codes, we want to attract more passengers to the platform, and therefore more rides for Heetch and the drivers.
