All procurement procedures are posted on this website, when you identify an electronic procedure that interests you and in compliance with the contractual terms, send your manifest interest to participate.
As a result, the contact you entered in the record as supplier, will receive by email the link to access the information of the procurement procedure or electronic event.
The first time you receive the link to participate in a contracting procedure or electronic event you will have to set up your username and password that will be used going forward to enter the SISCeP.  This step is done once for each contact person registered, you will have to verify that there are no duplicate accounts.

If this is the first time that you enter by the league to participate in a procurement procedure or electronic event, you must create your user name and password, which will serve permanently to enter the SISCEP *. This enablement is performed only once in the SISCEP * per registered contact, so you must verify that your account is not duplicated.​​

To continue to the contracting procedure or electronic event it is necessary for you to accept the terms for the electronic event.
