Other Transaction Authority (OTA): What It Is and How Small Businesses Can Win with It

Other Transaction Authority agreements let federal agencies bypass the Federal Acquisition Regulation entirely, replacing hundreds of pages of compliance requirements with streamlined, flexible response formats. For small businesses and nontraditional contractors, OTA represents one of the most accessible entry points into federal contracting. Here is how it works and how to win.

Other Transaction Authority, commonly called OTA, is one of the most powerful and least understood contracting mechanisms in federal acquisition. It allows certain federal agencies to enter into agreements with companies without following the Federal Acquisition Regulation, the detailed rulebook that governs nearly every traditional government contract. Because OTAs bypass FAR constraints, agencies have the flexibility to structure agreements that look nothing like a standard government contract. They can define their own terms, establish their own evaluation criteria, and accept responses in formats that range from a two-page whitepaper to a quad chart to a brief slide deck, depending on what best fits the requirement.

For small businesses, nontraditional defense contractors, and technology companies that have historically avoided federal contracting because of the administrative burden, OTA represents a fundamentally different opportunity. The barriers that make FAR-based contracting inaccessible to many commercial firms, including proposal complexity, compliance certifications, audit requirements, and mandatory contract clauses, are substantially reduced or eliminated in an OTA environment.

The Legal Foundation: What Authorizes OTA

Other Transaction Authority is not a single law. It is a set of statutory authorizations granted to specific federal agencies. There are three primary authorities in the defense context, all codified in Title 10 of the United States Code.

10 USC 4021 authorizes OTAs for basic, applied, and advanced research projects. Research OTAs are the oldest form and have been used by agencies including DARPA for decades to engage commercial and academic entities in technology development.

10 USC 4022 authorizes OTAs for prototype projects directly relevant to enhancing the mission effectiveness of Department of Defense personnel or improving platforms, systems, components, or materials proposed to be acquired or developed by DoD. Prototype OTAs are the most commonly used form today and the pathway through which most small businesses and nontraditional contractors engage with DoD under OTA.

10 USC 4023 provides authority for experimental purpose procurement and can result in a FAR-based contract, an OT prototype, an OT research agreement, or a grant depending on the specific circumstances.

Beyond DoD, eleven federal agencies have been granted some form of OTA by Congress, including NASA, the Department of Energy, the Department of Health and Human Services, the Department of Homeland Security, the Department of Transportation, the National Institutes of Health, the Federal Aviation Administration, and ARPA-H. Each agency's OTA authority is defined by its specific statutory grant, so the rules and permitted uses vary.

What Makes OTA Different from a FAR Contract

The most important distinction between an OTA and a traditional government contract is that an OTA is not subject to the Federal Acquisition Regulation. As documented in the DoD Other Transactions Guide published by the Office of the Under Secretary of Defense, OTAs neither follow a standard format nor include the standard terms and conditions or award processes required in FAR-based mechanisms. There is no equivalent to Section L and Section M, no uniform contract format, no mandatory FAR clauses, and no standard evaluation methodology.

This flexibility is intentional. The purpose of OTA is to enable the government to work with companies, particularly commercial technology companies, that would otherwise be unwilling or unable to accept the standard terms and conditions of a federal contract. A company that sells commercial software under standard commercial terms may be willing to enter into an OTA with the government because the OTA can incorporate commercial terms. That same company may refuse a FAR contract because the associated clauses are too burdensome or too incompatible with its standard business model.

For the government, OTA also speeds up acquisition. Without the procedural requirements of FAR Part 15, agencies can evaluate and award agreements in weeks rather than months or years. Without the requirement for a formal Request for Proposal and a lengthy evaluation process, agencies can conduct market engagement through informal events, open calls, or consortium mechanisms that move much faster than traditional procurement.

Importantly, a prototype OTA project can include provisions for a follow-on production contract or production OT that can be awarded directly to the successful prototyper without re-competition. This follow-on award authority is one of the most significant benefits of the prototype OTA pathway: if your company successfully delivers a prototype under an OTA, the government can award the production contract to you without conducting a new competition.

The Nontraditional Contractor Requirement

Prototype OTAs under 10 USC 4022 must satisfy at least one of four conditions in order to be awarded without competition:

The first condition is that a nontraditional defense contractor participates to a significant extent. A nontraditional defense contractor is defined in statute as an entity that is not currently performing and has not performed, for at least one year prior to the solicitation date, any contract or subcontract for DoD that is subject to full coverage under the Cost Accounting Standards. This definition encompasses most commercial companies, startups, small businesses that primarily serve commercial customers, academic institutions, and nonprofits.

The second condition is that all significant non-government participants in the project are either small businesses or nontraditional contractors.

The third condition is that at least one-third of the total project cost is contributed from non-federal sources. This cost-share requirement incentivizes commercial investment in the technology being developed.

The fourth condition is that the senior procurement executive for the agency makes a written determination that exceptional circumstances justify use of the other transaction authority.

For small businesses, the second condition is particularly accessible. If your company qualifies as a small business under the applicable NAICS code size standard, and the other significant participants in the effort are also small businesses or nontraditional contractors, the statutory requirement is met.

Who Uses OTA and How to Find Opportunities

OTA opportunities are not required to be posted on SAM.gov in the same way that FAR-based solicitations are, though many agencies do post notices there for transparency. The most common channels for finding OTA opportunities include agency-specific websites, consortium manager websites, and industry day events organized by the agency or a consortium manager.

Consortium OTAs are a particularly important channel for small businesses. Under a consortium OTA, the government establishes an agreement with a nonprofit consortium manager that acts as a contracting vehicle. Member companies of the consortium can then compete for task order opportunities issued under the consortium's OTA without each company having to negotiate a separate agreement with the government. Advanced Technology International (ATI), the National Security Technology Accelerator (NSTXL), and similar organizations manage major DoD OTA consortia and regularly publish calls for white papers and solution briefs from member companies.

OTA Response Formats: What You Actually Submit

Because OTAs are not subject to FAR Part 15, the response format is determined entirely by the agency or consortium manager issuing the solicitation. This is where OTA is dramatically different from traditional proposal writing.

Whitepapers are the most common OTA response format. A whitepaper is typically two to five pages and describes your company's technical approach to the problem, relevant capabilities, team qualifications, and proposed cost at a high level. The government uses whitepapers to screen the field and invite only selected companies to submit a full solution brief or proceed to negotiation. Writing a strong whitepaper requires understanding the government's problem at a technical level and communicating your solution clearly and concisely, without the volume and structure of a full FAR proposal.

Quad charts are a one-page, four-quadrant document that presents your solution, your organization, your team's relevant past performance, and your proposed cost or schedule in a single visual format. They are common in early-stage OTA engagements, industry days, and consortium opportunity responses where the government needs to quickly screen a large number of potential respondents.

Solution briefs and slide decks are used by many agencies and consortium managers in place of or in addition to whitepapers. The format is similar to a commercial pitch: a focused, visually clear presentation of the problem you are solving, your approach, why your team is credible, and what you are asking for in terms of funding and timeline.

Negotiated agreements replace the formal proposal and evaluation process of FAR contracting. Once the government has selected a company through whitepaper or solution brief screening, the parties negotiate the specific terms of the OTA directly. Because there is no FAR to constrain the negotiation, the final agreement can be structured to reflect commercial practices, shared intellectual property rights, and performance metrics that make sense for the specific project.

Step-by-Step Guide: How to Pursue and Win an OTA Opportunity

Step 1: Identify the right opportunity.
Monitor SAM.gov for OTA-related notices, including Broad Agency Announcements, Requests for White Papers, and consortium opportunity announcements. Visit the websites of major OTA consortium managers in your technology domain. Sign up for email notifications from agencies and consortium managers whose focus areas align with your capabilities.

Step 2: Confirm your eligibility.
Determine whether your company qualifies as a nontraditional contractor or a small business. If you have not held a DoD contract subject to full Cost Accounting Standards coverage in the past year, you likely qualify as a nontraditional contractor. If you are a small business under the relevant NAICS code, you meet the second statutory condition for prototype OTA awards.

Step 3: Join a relevant consortium if applicable.
If the opportunity flows through a consortium OTA, apply for consortium membership. Many consortium managers offer streamlined onboarding for small businesses and nontraditional contractors. Membership typically involves signing a consortium agreement and paying a modest membership fee, in exchange for access to all task order solicitations issued under the consortium's OTA.

Step 4: Write a compelling whitepaper.
Read the government's problem statement or Broad Agency Announcement carefully. Your whitepaper should open with a direct statement of how your solution addresses the stated problem, describe your technical approach at a level of detail sufficient to demonstrate feasibility, summarize the key personnel or team qualifications that make your company credible, and close with a high-level cost and schedule estimate. Two to five pages is the standard expectation. Lead with substance, not background about your company.

Step 5: Prepare a quad chart if required.
Structure the quad chart with your solution overview in the upper left, your technical approach or key differentiators in the upper right, your team and past performance in the lower left, and your proposed cost, period of performance, and any cost-share commitment in the lower right. Use graphics where they aid clarity. The quad chart must be self-explanatory because it may be reviewed without a verbal presentation.

Step 6: Engage in any oral presentation or follow-on discussion.
Many OTA processes include a brief oral presentation or technical discussion after the whitepaper screening. This is your opportunity to demonstrate depth of understanding and answer questions about your approach. Prepare your technical team, not just your business development staff, to engage in these conversations.

Step 7: Negotiate the agreement.
If selected, work with the government to negotiate the OTA agreement. Because FAR clauses are not required, you have room to negotiate intellectual property rights, data rights, reporting requirements, and payment terms that better reflect your commercial practices. Engage legal counsel familiar with OTA agreements during this step.

Step 8: Deliver the prototype and position for follow-on.
Execute the prototype project with the same rigor you would apply to any contract. Document your results clearly. If the OTA includes follow-on production provisions, successful prototype performance is your primary qualification for the follow-on award. Treat the prototype not just as a contract to deliver but as an audition for a much larger opportunity.

How ProposalApp Supports OTA Responses

ProposalApp is built to help you respond to any government solicitation quickly, and OTA opportunities are no exception. When you upload an OTA solicitation, Broad Agency Announcement, or consortium task order into ProposalApp, the Proposal Assistant reads the full requirement document and helps you structure a response that fits the requested format.

For whitepaper responses, ProposalApp drafts a structured narrative that aligns your company's capabilities to the government's stated problem, drawing from your capability profile and past performance library. For quad charts, ProposalApp generates the substantive content for each quadrant, which you then format visually for submission. For longer solution briefs or full proposal drafts requested in later OTA rounds, ProposalApp generates a compliance-aware draft organized around the evaluation criteria stated in the solicitation.

ProposalApp's Statement of Work review capability is particularly useful in OTA negotiations, where the government may share a draft SOW for comment before the agreement is finalized. The Proposal Assistant analyzes the draft SOW against your proposed technical approach, identifies ambiguities or scope gaps that should be addressed before you sign, and suggests language clarifications that better reflect what your team is committing to deliver.

Use ProposalApp's Find Opportunities page to search for OTA-related solicitations by searching keywords such as "Other Transaction," "White Paper," "Broad Agency Announcement," or "BAA" to surface active OTA opportunities in your technology domain.
