Small Business Innovation Research (SBIR) Small Business Technology Transfer (STTR)

Electronic Submission Process

The electronic application submission process for NIH SBIR and STTR grants is multi-step and can take between six to eight weeks. Each small business concern must complete five registrations, so it is important to start the process early. Applicants must use two separate registration systems, and eRA Commons, which is NIH's system for grants administration. Each system has its own registration and application requirements that must be met for successful grant submission.

Prepare to Apply
  • Confirm your small business concern (SBC) meets all eligibility requirements.
  • Develop an innovative research idea for your SBC. We strongly recommend that you discuss your research idea with the NIH Institute or Center SBIR/STTR program contact that is most closely related to your research topic.

Complete Five Registrations and Develop A Submission Plan

The registration process alone may take six to eight weeks, so it’s important to start early! All registrations must be completed prior to the application being submitted. It’s also important to make a submission plan that outlines the application preparation responsibilities, internal review and approval processes, internal deadlines, and post-submission responsibilities.

Each role in the submission process carries specific responsibilities. Program Directors/Principal Investigators (PD/PIs) work with their institute or organization to prepare the application, and pass the completed application on to their Authorized Organization Representative (AOR). Only AORs have the ability to actually submit a grant application to NIH via Please click here for more detailed information about the various roles in the submission process.

The SF424 SBIR/STTR (R&R) Application Guide, located here, contains registration and application instructions. We strongly recommend that you use the SBIR/STTR Annotated Form Set, found here, to guide you step-by-step through the submission process.

Five Registrations Overview:
  1. Dun and Bradstreet Universal Numbering System (DUNS) – All registrations require that applicants be issued a DUNS number. After obtaining a DUNS number, applicants can begin SAM, SBA Company, and eRA Commons registrations.

    Employer Identification Number (EIN) – The NIH requires both the EIN and a DUNS number prior to the issuance of a funding award. The EIN base for the organization is the IRS Tax ID number, for individuals it is their social security number, both of which are nine-digit numbers.

  2. System for Award Management (SAM) – SAM combines federal procurement systems and replaced CCR in July 2012. It can take a significant amount of time (days/weeks) in some scenarios to complete the registration or annual renewal process.
    • The annual renewal process may require as much time as the initial registration. Please be sure to initiate your SAM registration or annual renewal at least 6 weeks prior to you submission date.
    • SAM registration is required for prior to submission.
  3. – is a federal-wide portal to find and apply for federal grant funding. It is used by all 26 federal grant-making agencies and requires registration by the applicant organization. The applicant organization will need to designate an E-Business Point of Contact (E-Biz POC). The E-Biz POC will approve Authorized Organization Representatives (AORs) to submit applications.
  4. eRA Commons – eRA Commons is NIH’s Electronic Research Administration system that allows applicants, grantees, and NIH staff to access, share and transmit application/grant information.
    • eRA Commons requires registration by both the applicant organization and the Program Directors/Principal Investigators (PD/PIs). The organization’s Authorized Organizational Representative (also known at NIH as the Signing Official) must register or affiliate the PD/PI(s).
    • To check if the organization is already registered, go to the List of Commons Registered Organizations.
    • Register in Commons

  5. SBA Company Registry – All applicants are required to register at the SBA Company Registry prior to application submission and attach proof of registration in the Other Project Information, Other Attachments section of the application.

  • Viewing Window: After successful error-free submission, an application image will be assembled by the eRA Commons. PD/PIs and AORs/SOs will have two business days to check the assembled application. During this two-day viewing window, PD/PIs and AORs/SOs can reject the application, or let it automatically move forward to NIH staff for further processing and consideration.

Congratulations – You Have Successfully Submitted an NIH SBIR or STTR Grant Application! It will now move forward to peer review.
