Easily Switch Between Units

You are not bound to use one unit. The app allows any unit to be selected in the checkout and automatically calculates the right price. E.g. you can choose to input inches or feet for length based products. You can even switch between imperial and metric units if you want.

Offer Volume Discounts

You want to offer a discount, if a customer buys a certain amount of your product? You can easily create a volume discount for every 'sell-by' product. Simply choose the minimum order amount for the discount to be applied and set up a percentage- or fixed amount discount. The discount will be automatically applied in the cart, when the minimum order amount for a product is met.

Get Comprehensive Reports For All 'sell-by' Products

See how much you have sold and how much revenue you generated for every 'sell-by' product. You can even download the reports via csv export for even more comprehensive reporting purposes.
