It's really easy! The registration process takes less than 1 minute. Follow these steps to be able to publish for FREE.

Let's start


With your login you will be able to post purchases for FREE and bid as a supplier without limits.


What do you need to buy? Make a detailed description of what you need to buy. Use the categories and subcategories to make sure your order will get to the right suppliers.


Receive offers and watch your costs improve! Answer possible queries before you finalise your purchase and get better prices.


Contact the seller who has won the auction and arrange delivery of your purchase.


A reverse auction is a type of auction in which the roles of buyer and seller are reversed. In a regular auction, buyers compete to obtain a good or service by offering higher and higher prices, whereas in a reverse auction, suppliers offer lower and lower prices.
If you want to publish a purchase requirement, in the main panel or in My Purchases, you will see a button that says "New publication". Fill in as much detail as possible in all fields (it is very important as the more data you provide, the better the Supplier User will understand) in field 1, press the "Add items" button (you can add up to 15 products per publication) in field 2 and then "Save" to make a publication effective.
From the time the purchase requirement is published, until the day and time of the auction end set by the Buyer User. You will see it like this: Remaining time: 04d 19h 37m 24s.
There is no minimum amount, you just have to bid less than the previous bid
