How these numbers are counted
"Posted" counts are notices BidRover first recorded in the month, from the official procurement and grant sources it reads. They measure what BidRover saw, not every bid every buyer issued; a newly added source adds its open backlog in the month it was connected.
Bids withdrawn by the source, document-only records and Colombian direct awards are excluded. Closed bids still count in the month they were posted.
Days to deadline run from the day BidRover recorded a bid to its stated deadline; bids without a deadline, or with an impossible one, are left out of that figure. Notice types are read from the notice type or title (RFP, RFQ, invitation to bid and so on); bids that name no type are counted separately.
A place-month gets a report only when at least 30 bids were posted. Figures are recomputed every six hours.
