2. Blanket order for some products/services (ie, Default signage and storage, etc.) which would have on-going purchase in some specific period
Agency would issue a blanket order request to EM quarterly/annually. The request would include a breakdown of monthly estimated quantity/cost for each particular month. This process would help to shorten payment process when agency bill to EM.
Once agency could confirm actual quantity/cost that is used after end of each month, if the estimated cost in the blanket order for that particular month is different from the actual cost, agency would develop CE with an actual cost and seek endorsement from EM before start invoicing.
