From your home screen go to:

'Offers'

Here you can view how many offers of yours have been used aswell as how many new customers you've gained.

You can see the total amount spent through your offers vs how much you have discounted.

This is all information you can use to better manage and adjust your offers to boost business.

To view a breakdown for specific offers you've created select the offer and switch to 'Offer Used'

Here you can see a rundown of how many times that particular offer was used by day.

From the home screen you can select 'Analytics' and view overall business analytics that can be gathered through Voilo alongside how many offers have been used.
