How to Generate Resumes and Project Experiences for GSA MAS Proposals

When it comes to doing business with the U.S. federal government, one of the most strategic moves a professional services firm can make is securing a spot on the General Services Administration (GSA) Multiple Award Schedule (MAS). For firms across industries like consulting, engineering, IT, HR, and logistics, the MAS program is a gateway to long-term federal contracts, streamlined procurement, and increased visibility with government buyers.

But getting onto the Schedule isn't as simple as checking a few boxes. The proposal process is rigorous—and two of the most critical areas are where many firms struggle: resumes of key personnel and past performance project narratives. These sections aren't just paperwork—they're make-or-break components that validate your team's capability and your firm's credibility.

In this article, we'll walk through what the GSA MAS proposal entails, who it's relevant for, and how to expertly handle the resume and project experience components. We'll also show how a platform like Flowcase can make this complex process smoother, faster, and far more professional.

What is the GSA Multiple Award Schedule?

The GSA MAS, often simply called the Schedule, is a long-term government-wide contract that gives federal agencies access to commercial products and services at pre-negotiated prices. Rather than putting every individual project out for bid, agencies can use the Schedule to quickly and efficiently source what they need from vetted vendors.

Since 2019, GSA has consolidated what was once multiple schedules into a single MAS program with 12 large categories, simplifying the structure while maintaining specialized service offerings.

While there's no single "GSA MAS form," the proposal process involves a series of standardized templates and document submissions via GSA's eOffer system (for initial submissions) and eMod system (for modifications). These documents are structured differently depending on the industry and Special Item Numbers (SINs) you're applying under. However, across most service categories, you will be required to submit:

• Technical proposal (including key personnel qualifications)
• Past performance documentation (typically 2 relevant projects completed within the past 3 years)
• Pricing proposal with labor categories and rates
• Administrative documentation (compliance with TAA, SAM registration, etc.)

What companies should be on the GSA MAS?

The MAS is applicable to a wide range of professional services, including but not limited to:

• Management and consulting services
• Engineering and scientific services
• IT services
• Marketing and public relations
• Human resources and training services

The contracts under MAS can range from small consulting engagements to multi-million-dollar multi-year task orders. For any firm looking to establish a long-term presence in the federal market, it's a critical vehicle to be on.

General tips for preparing your GSA MAS proposal

Before we dive into resumes and past projects, here are a few high-level tips for preparing your GSA MAS proposal successfully:

Understand the SINs (Special Item Numbers)

Each SIN represents a specific category of service or product offered through the Schedule. Think of them as product/service codes. For example, SIN 541611 covers Management and Financial Consulting, Acquisition and Grants Management Support, and Business Program and Project Management Services. You must align your offering, resumes, and past projects to the SINs you're targeting. The SINs you select determine how your proposal is evaluated and what opportunities you'll have access to once awarded.

Don't cut corners on formatting

GSA reviewers are accustomed to very clear, well-organized submissions. Make it easy for them to say yes by using consistent formatting, clear section labels, and logical structure throughout.

Use real metrics

Whether you're describing a project or a team member's contribution, quantifiable impact always helps. Statements like "improved process efficiency by 40%" are more powerful than vague descriptions.

Be thorough but concise

Every section of your GSA proposal matters, but overly long or wordy responses can hurt more than help. Focus on relevance and clarity.

What to include in GSA MAS resumes and past performance sections

Let's talk about the two areas that require the most narrative thinking: resumes of key personnel and project experience. These are evaluated separately in the GSA review process but work together to validate your firm's capabilities.

Key personnel resumes

GSA expects your key personnel resumes to demonstrate that your team has the capability and expertise to deliver under the SINs you're bidding for. While they aren't bound by a federal form like the SF 330, your resumes should include:

• A short professional bio
• Relevant education and certifications
• Specific experience relevant to the SIN
• The individual's role in the company and in past projects

‍

Tips for crafting GSA-ready resumes:

• Tailor to the SIN: Only include experience and skills that match the services you're proposing under each SIN.
• Avoid generic descriptions: Use clear, impact-driven language. For example, "Led a cross-agency project to streamline IT procurement, resulting in 30% faster cycle times."
• Be consistent: If you're submitting resumes for multiple SINs, ensure that role titles, dates, and achievements are aligned. Inconsistencies raise red flags.
• Use plain language: GSA reviewers aren't always technical experts in your field. Avoid jargon or explain it clearly.
• Align with pricing: Ensure your personnel qualifications correspond with the labor categories and rates in your pricing proposal.

‍

Project experience / past performance

The past performance section is your proof of capability. GSA typically requires 2 relevant projects completed within the past 3 years per SIN, and these should align directly with the services you're bidding on.

Each project narrative should include:

• Client name and industry
• Scope of work
• Duration and timeline
• Challenges faced and how they were addressed
• Outcomes and measurable results

‍

Tips for writing strong GSA project descriptions:

• Keep it factual but compelling: Think of it like a mini case study—what problem did you solve and how did your team do it?
• Use consistent structure: This helps reviewers compare and assess across projects and improves readability.
• Don't oversell: GSA evaluators know what realistic success looks like. Keep the tone confident but grounded.
• Tie it back to the SIN: If a project included multiple services, emphasize the parts most relevant to the SIN.

‍

Post-award considerations

Keep in mind that your resumes and past performance documentation aren't just important for getting on the Schedule—they're also critical for competing for task orders after you receive your contract. Agencies will evaluate your team's qualifications and past work when deciding between multiple MAS contract holders, so maintaining current, compelling documentation is an ongoing requirement.

How Flowcase simplifies this process

Creating GSA-ready resumes and project narratives is a manual, time-intensive task—especially when multiple SINs and team members are involved. Flowcase is built specifically to handle this kind of complexity with ease.

With Flowcase, your team's resumes are standardized across the firm, using approved terminology and formats. You can:

• Search across all employees to find the most relevant experience for each SIN
• Maintain consistent labor category descriptions across proposals
• Tailor resumes without creating versioning chaos

By removing version control issues, centralizing skills and case study data, and providing export-ready templates for federal forms, Flowcase becomes a critical part of your GSA proposal toolkit—not just for initial submission but for ongoing task order competitions.

Wrapping up

Submitting a winning GSA MAS proposal isn't about outlining all of your firm's achievements. It's about carefully choosing your most relevant ones, explaining them in the clearest and most targeted way, and formatting them so that they're easily digestible for the evaluators. As part of this, your resumes and project experience are your proof points. Done well, they can secure your place on the Schedule and open doors to steady federal revenue for years to come.

If your team is stuck in shared drives and Word docs, Flowcase can transform how you manage and present your firm's expertise. It's resume and case study management made for the proposal-driven world of government contracting.
