GSA MAS Offer Rejection: Top Reasons New Offers Get Rejected
By Maureen Meyer on June 15, 2026
Submitting a GSA MAS offer requires careful planning. Contractors must gather documentation, develop pricing, select SINs, and demonstrate past performance. Between gathering documentation, developing pricing, selecting Special Item Numbers (SINs), and demonstrating past performance, the process requires careful preparation and attention to detail. This guide is designed to help contractors generate a compliant new offer that can move through the GSA review process without unnecessary delays, clarifications, or rejection notices. Below, we detail the most common mistakes that lead to GSA MAS new offer rejections. We’ll explain what to do if your offer is rejected and how to strengthen your next submission.
Common Mistakes That Lead to GSA MAS New Offer Rejections
- Selecting the wrong SIN. Each SIN has a specific scope, documentation requirements, and evaluation criteria. Contractors sometimes select a SIN that appears to align with their offerings, only for the Contracting Officer (CO) to determine that the products or services fit better under a different category. For example, a company may attempt to pursue a Professional Services SIN using project examples that are more closely aligned with Information Technology (IT) services. To avoid this issue, thoroughly review the Solicitation’s SIN descriptions and ensure your commercial experience, past performance examples, and technical narratives directly support the SINs you propose.
- Weak financials. GSA evaluates financial responsibility to determine whether a contractor can sustain operations while supporting federal business growth. Negative net worth, ongoing losses, excessive debt, or inconsistent revenue trends may lead to a rejection. Even if your company is operationally strong, financial statements that suggest instability can create concerns during the evaluation process. Before submitting an offer, review your financial position carefully and be prepared to explain any unusual circumstances, losses, or temporary setbacks through supporting documentation.
- Past performance that does not align with the proposed scope. COs want evidence that you have successfully performed work similar to what you intend to offer through your GSA Schedule. Contractors often run into trouble when they submit projects that are only loosely related to the proposed SIN, or when they attempt to offer services outside of their demonstrated expertise. Focus only on your core competencies and select recent projects that clearly reflect the products or services you intend to sell through the Schedule.
- Negative customer feedback. GSA reviews past performance information to assess reliability, quality, responsiveness, customer support, and overall business relations. Because portions of the review process may rely on customer feedback and references, contractors are surprised by unfavorable responses from previous clients. Contact references before submission, verify that they are willing to participate, and address any customer concerns proactively before they become part of the evaluation.
- Incomplete or inaccurate documentation. Missing signatures, omitted forms, outdated templates, incorrect formatting, or incomplete responses are among the most preventable reasons for rejection. Even highly qualified contractors will be rejected if the required documents are absent or improperly completed. Develop a detailed compliance checklist and verify that every required document has been completed using the most current Solicitation requirements before submission.
- Pricing that is not considered fair and reasonable. GSA compares proposed pricing against historical sales data, market benchmarks, and pricing offered by existing Schedule holders. Prices that appear inflated may raise concerns about competitiveness, while prices that are unusually low can create concerns about sustainability. Contractors should conduct market research and validate discount structures. They should also ensure pricing remains consistent across invoices and proposal documents.
- Inconsistent pricing documentation. Even when proposed rates appear reasonable, discrepancies between invoices, pricing templates, and supporting documentation can lead to questions about accuracy and transparency. For example, if discounts shown on customer invoices do not match the discounts disclosed elsewhere in the offer, the CO may question the validity of the submission. Conduct a thorough audit of all pricing-related documents before submitting your offer.
- Outdated or insufficient past performance documentation. Many service-based SINs require recent project examples, often within the previous two years. Contractors sometimes rely on older projects or fail to provide enough detail regarding scope, performance outcomes, and customer satisfaction. Strong project narratives should clearly demonstrate the work performed, the results achieved, and how the project aligns with the proposed SIN.

- Overlooking subcontracting plan requirements. While small businesses are generally exempt, large businesses must provide a compliant subcontracting plan that supports GSA’s socioeconomic goals. Failure to include the required documentation or provide adequate detail can result in rejection. Contractors should confirm whether subcontracting plan requirements apply to their organization early in the offer preparation process.
- Failure to keep up with current Solicitation requirements. GSA periodically updates the MAS Solicitation through refreshes that may change templates, reporting requirements, SIN descriptions, or supporting documentation requirements. Contractors who rely on outdated guidance often discover late in the process that required forms or instructions have changed. Always verify that you are using the latest Solicitation version and associated templates before beginning your submission.
What to Do If You Receive a Rejection
Receiving a rejection can be frustrating. Many contractors spend months preparing a GSA MAS offer before submission.
Clarification Requests vs. Formal Rejections
A clarification request is a request for additional information, explanation, or supporting documentation. Clarifications do not mean your offer is being rejected. They are part of the normal review process and provide an opportunity to address questions raised by the CO. Responding thoroughly and within the stated deadline is critical.
A rejection, on the other hand, means GSA has closed the offer and removed it from consideration. Once a formal rejection is issued, the offer cannot be reopened, and contractors must submit a new offer.
Steps to Take After a Rejection
If your offer is rejected, begin by carefully reviewing the rejection notice. Identify each issue cited by the CO and determine whether it relates to pricing, scope, financial responsibility, past performance, or responsiveness. Avoid immediately resubmitting without addressing the underlying concerns.
Next, conduct a complete review of your original submission. Compare the rejection notice against the current Solicitation requirements and identify any compliance gaps. Update all documentation, verify that you are using the latest templates, and correct any inconsistencies that may have contributed to the rejection.
For a second submission, contractors must also prepare a formal response explaining how the issues identified during the original review have been addressed. This response should clearly outline the corrective actions taken. Providing a structured explanation demonstrates that the concerns raised during the initial evaluation have been thoroughly resolved.
Preparing a Stronger Resubmission
Before resubmitting, consider conducting an internal compliance review or independent quality assurance review. A fresh set of eyes can often identify issues that were overlooked during the initial preparation process.
Final Thoughts
Avoiding common GSA MAS offer mistakes can save contractors months of delays and significantly improve the likelihood of receiving a contract award. By taking the time to avoid common pitfalls, contractors can improve their chances of moving through the evaluation process efficiently and securing their Schedule in a timely manner.
