NASA SBIR/STTR Program Solicitation Details | 6. Submission of Proposals

6. Submission of Proposals

6.1 Submission Requirements

NASA uses electronically supported business processes for the SBIR/STTR Programs. An offeror must have Internet access and an email address. Paper submissions are not accepted. 

The EHB for submitting proposals is located at under the Handbooks section. The EHB has been updated for the 2018 cycle to look more modern and be easier to use. The Proposal Submissions EHB guides the firms through the steps for submitting an SBIR/STTR proposal. All EHB submissions are through a secure connection. Communication between NASA’s SBIR/STTR Programs and the firm is primarily through a combination of EHBs and email.

6.2 Submission Process

New SBCs must register in the EHB to begin the submission process. Returning firms can use the same account that they have used for previous submissions. Firms are encouraged to start the proposal process early, to allow for sufficient time to complete the submissions process. It is recommended that the Business Official, or an authorized representative designated by the Business Official, be the first person to register for the SBC. The SBC’s Employer Identification Number (EIN)/Taxpayer Identification Number is required during registration. 

Note: The designated firm admin, typically the first person to register your firm, is the only individual authorized to update and change the firm level forms. 

For successful proposal submission, SBCs shall complete all forms online, upload their technical proposal in an acceptable format, and have the Business Official and Principal Investigator electronically endorse the proposal. Electronic endorsement of the proposal is handled online with no additional software requirements. The term “technical proposal” refers to the part of the submission as described in section 3.3.4. 

STTR: The Research Institution is required to electronically endorse the Research Agreement prior to the SBC endorsement of the completed proposal submission.

 6.2.1 What Needs to Be Submitted 

The entire proposal package must be submitted via the Submissions EHB located on the NASA SBIR/STTR website. 

Note: Other forms of submissions such as postal, paper, fax, diskette, or email attachments are not acceptable. 

The proposal package includes: 

  1. Contact Information
  2. Proposal Certifications
  3. Proposal Budget
  4. Research Agreement (STTR only)
  5. Proposal Summary
  6. Technical Proposal (upload)
  7. Briefing Chart
  8. I-Corps Opt-In (Phase I only)
  9. Firm Level Forms (completed once for all proposals submitted to a single Solicitation) 

6.2.2 Technical Proposal Submissions 

NASA converts all technical proposal files to PDF format for evaluation. Therefore, NASA requests that technical proposals be submitted in PDF format. 

Note: Embedded animation or video, as well as reference technical papers for “further reading” will not be considered for evaluation. 

Virus Check 

The offeror is responsible for performing a virus check on each submitted technical proposal. As a standard part of entering the proposal into the processing system, NASA will scan each submitted electronic technical proposal for viruses. 

Note: The detection, by NASA, of a virus on any electronically submitted technical proposal, may cause rejection of the proposal.

6.2.3 Technical Proposal Uploads

Firms will upload their proposals using the Submissions EHB. Directions will be provided to assist users. All transactions via the EHB are encrypted for security. Firms cannot submit security/password protected technical proposal and/or supporting documentation, as reviewers may not be able to open and read the files. 

You may upload the technical proposal multiple times, with each new upload replacing the previous version, but only the final uploaded and electronically endorsed version will be considered for review.  Before you can submit the proposal package, you must download the entire proposal package and certify that you have reviewed it to ensure that you have uploaded the correct materials.
