Should I contact ONAC to enable payment by PSE, how do I make the payments and upload the voucher in SIPSO?

Answer: No, you do not have to contact ONAC to enable the payment by PSE, the CAB must enter the option “Upload payment support” in the “manage payments” menu, in the space provided to upload the scanned invoice with the bank stamp or the canceled PSE voucher (you can upload the necessary payment supports unifying everything in a single PDF file).

If the CAB is of a public nature, you must attach in a single PDF the service contract together with the CDP (Certificate of Budget Availability), RP (Budgetary Register) or Payment Resolution, as applicable.

Step-by-step information on how to upload the payment supports can be found in the “Instructions for user registration, application creation and payment administration in the SIPSO system”, available on the SIPSO microsite on the ONAC website https://site.onac.org.co/sipso/.
