Key takeaways

  • Vehicle access is a market position, not a contract — task orders are where revenue happens.
  • Read the ordering guide before bidding a task order; format and evaluation rules differ from open-market RFPs.
  • Fair-opportunity task orders move fast, often with 10 to 15 day response windows.
  • Track on-ramp windows well in advance; they open rarely and close quickly.

How work is ordered

After award, work is issued as task orders (services) or delivery orders (products). Multiple-award IDIQs require fair opportunity among holders; single-award IDIQs let the agency order directly.

Getting on the vehicle

You get on by winning the base IDIQ competition, which is a full proposal effort with technical, management, past performance, and price volumes. Missing the base competition usually means waiting years for the recompete.

Winning task orders

Treat the base award as a market-entry investment and budget separately for task order capture. Firms that win IDIQ seats and then under-resource task order bidding end up with impressive contract vehicles and no revenue.
