Checklist for eMod Technical Compliance

The GSA eMod system is essential for modifying MAS contracts, whether you’re updating prices, adding products, or making administrative changes. But here’s the catch: errors in compliance can lead to delays, rejections, or even penalties. This guide simplifies the process by breaking it into clear steps:

• Pre-Access Setup: Secure a FAS ID, enable multi-factor authentication, and verify contract details.
• Technical Requirements: Use supported browsers, check pop-up settings, and ensure forms are properly filled.
• Document Preparation: Align all forms (e.g., SF 30, CSP-1) with GSA’s requirements and keep records audit-ready.
• Modification Types: Each modification – Administrative, Pricing, Additions – requires specific documentation and steps.
• After Submission: Monitor your modification status, respond to GSA requests, and confirm updates in GSA systems post-approval.

Accurate submissions and ongoing compliance are non-negotiable to maintain your GSA contract. If this feels overwhelming, consider professional help to streamline the process and avoid costly mistakes.

Pre-Access Requirements

Before diving into the eMod submission process, there are a few technical steps you need to tackle. These steps ensure you’re set up correctly and help you avoid unnecessary delays later on. Here’s what you need to know to get started.

Set Up FAS ID and Multi-Factor Authentication

Every eMod user must have their own FAS ID account – shared accounts are not allowed. If you’re part of a team managing contract modifications, each team member needs to register individually, using their dedicated work email.

To create your FAS ID, register with your work email, which serves as your primary identifier in the GSA system. After registration, you’ll need to enable multi-factor authentication (MFA) – a required security measure for all FAS ID users.

MFA options include SMS text messages, email codes, or authenticator apps. Once you’ve set up MFA, test it by logging into a GSA application, such as the eOffer/eMod Help Center. During this process, double-check that your DUNS/UEI and contract number match your records. If there’s a mismatch, you won’t be able to move forward with your modifications.

Once your credentials are verified, you’re ready to move on to the next steps in the process.

Verify Contract and User Role Information

Before starting a modification, take a moment to confirm your contract details against your official award documents and GSA’s current records.

Make sure your contract is active – expired, suspended, or closed-out contracts are not eligible for modifications. Also, verify that your user list is up to date. If former employees or unauthorized users are still listed, it could cause issues. Only current, authorized personnel with the correct roles should appear in the system.

With your contract details and user roles squared away, it’s time to ensure your technical setup is ready.

Review System and Browser Requirements

The eMod platform works best with specific browsers and security settings. Using an unsupported browser or overly restrictive security configurations can lead to errors. Check the eOffer/eMod Help Center for the latest list of supported browsers – GSA typically supports recent versions of major browsers.

Pop-up blockers are another common issue. Make sure pop-ups are enabled for eoffer.gsa.gov and other related GSA domains. If your IT team manages your security settings, you may need their help to adjust firewall rules or other configurations that could interfere with uploads.

Your browser’s security settings also play a role. The eMod system requires current TLS protocols, and overly strict settings can trigger errors or timeouts. If you run into problems, start by clearing your browser cache, checking your pop-up settings, and confirming your MFA status. For additional help, the eOffer/eMod Help Center provides troubleshooting guides and FAQs that address common technical challenges.

Lastly, ensure you have the right tools to handle GSA forms. Most forms are in PDF format with fillable fields, so you’ll need an up-to-date PDF reader. Test opening a sample form beforehand to avoid surprises. GSA’s "Before You Begin – eMod Checklist" is a handy resource for catching potential issues early.

Core Technical Compliance Checklist

Once you’ve met the pre-access requirements, it’s time to ensure your submission aligns with GSA’s technical standards. This step is crucial for a smooth modification process.

Choose the Correct Modification Type

First, identify the type of modification that matches your intended change. GSA offers eight eMod modification categories: Administrative, Pricing, Technical, Terms & Conditions, Additions, Deletions, Legal, and Cancellations. Each category has its own specific documentation and review criteria.

For instance, updating your company address falls under Administrative modifications, while adding new products or services is classified as Additions. Adjusting your pricing structure? That’s a Pricing modification. Keep different changes separate – if you need to update your address and add new products, you’ll need to submit two separate eMod requests.

Prepare Required GSA Forms and Templates

Download the latest MAS solicitation and templates directly from GSA. Commonly needed forms include:

• SF 30: Amendment of Solicitation/Modification of Contract
• CSP-1: Commercial Sales Practices disclosure (when applicable)
• Price Proposal Templates: Specific to your SINs

For certain SINs, like COMSATCOM, follow the relevant program-specific checklists. Keep in mind that MAS consolidation and frequent solicitation updates mean older forms may no longer be valid. Always double-check that your SINs, pricing templates, and terms comply with the latest guidance.

Check Document Consistency and Completeness

GSA reviewers will examine your submission for consistency and accuracy. Supporting documents must align with one another. For example:

• The Price Proposal Template should match product descriptions.
• CSP disclosures must accurately reflect your discounting practices and Most Favored Customer relationships.

Submissions must meet MAS solicitation requirements. According to the GSA Multiple Award Schedule Contractor Compliance Checklist (March 2022), all modifications and updates must be submitted through eOffer/eMod – email or paper submissions are not accepted. Additionally, some actions, like submitting contract data to GSA Advantage!, are time-sensitive. For example, updates must be completed within 30 days after exercising an option.

Keep detailed records of all modifications, pricing, and correspondence. These documents must back up every disclosure in your eMod and stay audit-ready. The GSA Office of Inspector General frequently audits submissions to ensure consistency between eMod filings, CSP disclosures, and actual pricing practices.

Confirm Compliance Statements and Certifications

Double-check that all certifications and representations are accurate. This includes:

• Trade Agreements Act (TAA) compliance
• Section 889 telecom prohibitions
• Small business size status and socio-economic designations
• Any environmental or safety certifications

Pay close attention to TAA compliance. Verify that the country of origin for all products aligns with your documentation. If you’ve added new products or changed suppliers, ensure all items still meet TAA requirements. Similarly, Section 889 of the FAR (52.204-25) is a critical focus area. If your offerings include telecommunications or video surveillance equipment, make sure your attestations are up to date.

Your CSP disclosure (if required) must reflect your current business practices. If your discounting policies or customer relationships have changed, update your CSP accordingly. To stay on top of deadlines and recurring reporting requirements, consider maintaining an internal GSA compliance checklist and calendar.

Navigating GSA’s paperwork and compliance rules can feel overwhelming. As GSA Focus aptly puts it:

Dealing with compliance… Hiring lawyers, googling 1,000 things a day, etc..

If you’re unsure about your compliance statements or need help, seeking specialized assistance might save you from costly delays.

Modification Type-Specific Checklists

Building on the central compliance steps, the following checklists outline the specific documentation and requirements for each type of modification.

Administrative Modifications

Administrative modifications involve updates to your company information that don’t impact your contract’s scope or pricing. Common changes include updates to your business name, address, points of contact, or authorized negotiators.

Before submitting an administrative eMod, make sure your SAM.gov registration is up to date. GSA will cross-check your eMod submission against your SAM data, and any discrepancies could lead to questions or rejections. For name changes resulting from mergers or acquisitions, update SAM first, then include supporting documents like legal name change certificates or articles of incorporation with your eMod.

When updating points of contact or authorized negotiators, provide their full names, titles, email addresses, and phone numbers. If replacing a contract administrator, ensure the new contact has access to your eFAS account and understands their responsibilities under your GSA Schedule.

For address changes, include proof of your new location, such as a lease agreement, utility bill, or other official documentation. This is especially critical if the move crosses state lines, as it may affect your socio-economic status or small business size standards.

Always keep copies of all supporting documents in your contract file for future audits.

Adding Products or Labor Categories

Adding new products or services to your GSA Schedule requires more extensive documentation compared to administrative updates. You’ll need to show that your new offerings meet GSA’s technical standards, comply with trade agreements, and align with your awarded Special Item Numbers (SINs).

Start by confirming that your new offerings fall under your existing SINs. If needed, secure additional SINs by reviewing the latest MAS solicitation, as SIN definitions can change over time.

Ensure all new products meet TAA requirements by including updated supplier certifications and country-of-origin statements. Keep manufacturing documentation on hand for GSA’s review.

Use the most current GSA pricing templates for your SINs, as older versions may not be accepted. Provide detailed product descriptions, manufacturer part numbers, and technical specifications. For labor categories, include position descriptions, minimum qualifications, and hourly rates that align with your awarded contract type. Remember, only Fixed Price, Time & Materials, or Labor Hour contracts are allowed under GSA Schedules – cost-reimbursement contracts are not permitted.

Certain SINs have unique requirements. For example, if you’re adding the COMSATCOM SIN, you’ll need to submit a complete COMSATCOM modification checklist, including technical capability statements, past performance documentation, and specific certifications.

If your new products or services require Commercial Supplier Agreements (CSAs), End User Licensing Agreements (EULAs), or Terms of Service (ToS), make sure these align with GSA’s terms and conditions. Prohibited clauses, like automatic renewals without notice or unilateral price increases, must be removed.

For contractors holding any of the 181 SINs eligible for Transactional Data Reporting (TDR) who haven’t transitioned yet, you must submit a "Participate in TDR" modification by September 30, 2025. Once approved, all SINs under your contract will be subject to TDR reporting requirements. Submit this modification well in advance to allow time for GSA to review.

Pricing and Economic Price Adjustment Modifications

Pricing modifications require precise documentation and strict compliance with established discount relationships.

Start by identifying the Economic Price Adjustment (EPA) mechanism tied to your contract. Depending on your agreement, this could include fixed escalation rates, commercial price list changes, or market index adjustments. Any pricing changes must align with the EPA structure already in place. Switching mechanisms will require a separate modification.

Submit current price lists and market data to justify your proposed rates. GSA expects your new prices to be fair and reasonable compared to what you offer other customers.

Make sure your Most Favored Customer (MFC) and discount relationships remain intact after the pricing change. If your contract requires offering GSA the same or better pricing than your best commercial customer, verify that your new rates meet this obligation. If your commercial discounts have changed, you may also need to update your Commercial Sales Practices (CSP) disclosure alongside the pricing modification.

For price reductions, submit the new rates with effective dates and update your GSA Advantage!® listings promptly. Your listed prices cannot exceed your awarded GSA rates.

If requesting a price increase, be prepared for additional scrutiny. Provide a detailed cost breakdown, supplier price increase notices, or other supporting evidence.

Ensure consistency across all pricing documents. Your price proposal template, CSP disclosure, and any supporting invoices or catalogs should align perfectly. Discrepancies can lead to compliance audits.

Keep detailed records of all pricing changes, including the rationale behind them. GSA’s Office of Inspector General frequently audits contractor pricing to ensure compliance with MAS pricing policies.

Submission, Tracking, and Post-Approval Steps

Once your modification package is ready, the final phase demands precision. Submitting an eMod creates an electronic proposal record that goes directly to your GSA Contracting Office, along with all the necessary attachments. The quality of your submission plays a big role in how quickly it gets approved.

Verify Submission Before Sending

Before hitting "submit", take a moment to double-check everything using GSA’s pre-submission checklist. Make sure you’ve selected the correct contract number, chosen the right modification type, and filled out all required fields. Pay attention to how your attachments are labeled – clear, descriptive filenames make a difference. For example, instead of using something generic like "Document1.pdf", opt for names like "2025-12-08_Price_List_SIN_54151S.pdf" or "TAA_Certification_NewProduct_Dec2025.pdf."

Keep all your submission files in a dedicated, well-organized folder. Sorting them by modification number and date not only keeps things tidy but also makes audits and compliance reviews easier down the line.

Watch out for common mistakes that could delay the process, such as incorrect contract numbers, incomplete forms, unsigned documents, or unsupported file formats. To avoid these pitfalls, consider creating an internal pre-submission checklist that mirrors GSA’s requirements while adding your own company-specific quality checks.

Once your submission is sent, shift your focus to monitoring its progress and staying responsive.

Monitor Status and Respond to GSA Requests

After submitting, regular monitoring is key to keeping the process on track. Log into the eMod portal frequently to check for status updates and messages from your Contracting Officer. Assign someone – usually your GSA contract administrator or compliance lead – to oversee the eMod’s progress and handle any follow-up actions.

Treat each eMod like a mini-project within your broader contract management system. Use a central calendar to tie eMods to important internal events, such as catalog updates, new product launches, or wage determination changes.

Maintain a detailed log of each eMod’s milestones and responses, and review it every quarter to identify any discrepancies. Keeping progress checkpoints visible to your team – like "submitted", "CO requested clarifications", "pending internal data", and "approved" – helps everyone stay aligned and minimizes delays.

Validate Post-Approval Updates

Once your modification is approved, confirm that GSA’s systems accurately reflect the changes. Check your GSA Advantage! catalog to ensure updated products, pricing, and terms are displayed correctly. Verify that details like part numbers, descriptions, and photos align with the approved modification. Additionally, confirm that GSA eLibrary shows the updated contract information, including SINs, contact details, and socio-economic designations.

GSA’s compliance guidelines often specify deadlines for certain actions. For instance, contractors must submit electronic contract data for GSA Advantage! publication within 30 days after an option exercise. Some tasks tied to specific clauses may require action as early as 165 days before the contract’s end date.

Update your internal systems and public-facing materials to match the approved GSA terms. This may include revising internal price lists, quoting tools, marketing materials, and your company website. Any inconsistency between your advertised terms and the approved contract could trigger a compliance audit.

For audit readiness, ensure each modification has a complete file. This should include the eMod confirmation, award modification document, all attachments, price support documentation, and any communications with GSA. Save a local copy of your full submission package in your contract repository. Conduct periodic internal reviews – quarterly checks work well – to ensure all approved modifications are fully implemented across systems and external platforms.

The table below highlights key actions from submission through audit preparation:

Additionally, GSA provides modification checklists tailored to specific SINs, such as the COMSATCOM Mod Checklist, which can serve as helpful templates for creating internal checklists. Maintaining consistent, organized documentation for every modification is essential for successful IOA reviews and GSA Office of Inspector General audits.
