In the sign in overview, you can see at a glance whether a customer has bought a product with which he pay for the activity or not. If he has not yet bought a product, you can see that in the column “products” "no product" is selected and additionally underlined in red. In that case you can sell him a suitable product very quickly by clicking on the cart icon.
A new screen shows up and you can select the product you want to sell to this customer. In case that you offer a lot of products, you have to scroll down to edit the sale and complete it.
By clicking the pencil icon, you can edit the product, e.g. give discounts, determine the validity or set the number of units.
Afterwards you have to select the payment method and you can choose whether to print a receipt, create an invoice, send an email to the customer or to continue without one of these functions (receipt and invoice will still be created in the background, so they are available if necessary). By clicking on the corresponding button you conclude the sale. The product is assigned to the customer directly in the sign-in overview and the first booking is automatically deducted.
