How to Add Products or Services to Your GSA Schedule Contract
After your GSA Schedule contract is awarded, your catalog is not static. You can add new products, services, and labor categories through the eMod system. This flexibility allows you to keep your Schedule current with your commercial offerings and respond to market demand — but each addition requires documentation, pricing justification, and CO approval. Understanding the modification process keeps your Schedule competitive and avoids gaps between what you offer commercially and what's on your contract.
Types of Additions You Can Make
You can add: new products under an existing SIN (adding new items to your product catalog), new labor categories under a services SIN (adding new job titles or seniority levels), new SINs (expanding into new service or product categories), and Order-Level Materials (OLM) if you are adding OLM capability to a services SIN. Each addition type has slightly different documentation requirements. New SINs require a full capability demonstration similar to the original application for that SIN.
The eMod Process for Additions
Log into eMod at eoffer.gsa.gov and select "modification" for your contract. Select the modification type — for additions, this is typically a "mass modification" response or a "voluntary modification" initiated by you. Complete the required sections: describe the additions, provide pricing justification (commercial pricing documentation, market data, or CSP updates), and upload supporting documentation. Submit the modification for CO review. The CO reviews the addition, may negotiate pricing, and approves or rejects with findings.
| Addition Type | Documentation Required | Typical Timeline |
|---|---|---|
| New product under existing SIN | Commercial pricing, TAA certification | 2–6 weeks |
| New labor category | LCAT description, commercial rate documentation | 2–6 weeks |
| New SIN addition | Technical capability, past performance, pricing | 4–12 weeks |
| OLM capability | Written attestation of OLM procedures | 2–4 weeks |
Pricing New Additions
New items added to your Schedule must also be at or below your MFC pricing for those items. If you are adding items that are new to your commercial catalog, price them using the same methodology as your original Schedule pricing — commercial price less the negotiated discount. If the CO identifies that your proposed prices for additions are significantly above market or above your commercial pricing, they will request a price reduction before approving the modification. Prepare your pricing documentation before submitting the modification to avoid delays.
