The invitation to bid/request for expression of interest may be advertised through the newspaper, the organization's website, Philippine Government Electronic Procurement System's (PhilGEPS) website, or in any conspicuous place within the organization's premises. A continuous period of 7 calendar days is required for website posts, starting from the date of advertisement. For Northern Samar's hospital management services, the organization's initial preference was to post the advertisement only through PhilGEPS, but it later decided to advertise through a national daily to help ensure wider dissemination and better competition. The same approach could be made for the organization's hospital management services.
