A new MAS awardee in 2026 went looking for the Schedule Input Program everyone told them to use, and it was not the tool anymore. GSA had moved catalog management to a new system, and the old guides they were following described a workflow that no longer applied. If your catalog is how buyers find you, you cannot afford to manage it through a retired system.
The FAS Catalog Platform (FCP) is GSA’s web-based system for managing the product and service catalogs that publish to GSA Advantage, and it is now mandatory for new MAS awards. As of November 6, 2025, all new MAS contracts automatically onboard into FCP, and starting April 6, 2026, contractors moving through FCP onboarding are required to update their Terms and Conditions (T&C) file. The legacy Schedule Input Program (SIP) is being retired.
What Is the FAS Catalog Platform, and What Replaced?
FCP is the system contractors use to upload, manage, and update the catalog data that appears on GSA Advantage. It replaces the older Schedule Input Program (SIP) workflow that vendors used for years.
The shift in plain terms:
- New MAS awardees are onboarded into FCP automatically. Since November 6, 2025, new contracts go straight into the platform.
- FCP manages both product and service catalogs. The current focus has been transitioning service catalog contractors, a group SIP handled awkwardly.
- GSA is requiring migration to FCP through a baseline modification for existing contractors, so this is not optional housekeeping.
- SIP is on its way out. Advice built around SIP is increasingly stale, which is why most “how to use GSA Advantage” content online no longer matches reality.
If your mental model of catalog management is still SIP, that is the first thing to update.
What Is the T&C File Update, and Do You Need It?
The Terms and Conditions file update is a required step in FCP onboarding starting April 6, 2026, and it applies especially to newer contractors and anyone making a baseline catalog action. It is how your contract terms get correctly represented in the platform.
You likely need to address the T&C file if you are:
- A contractor awarded after August 28, 2025, moving through FCP First Steps onboarding.
- A brand-new FCP user setting up catalog management for the first time.
- An existing FCP user adding catalog offerings that require a new Baseline action.
Getting the T&C file right matters because it sits underneath everything else. A catalog built on an incorrect or incomplete T&C foundation creates downstream problems that are harder to fix than to prevent.
If you were awarded recently or are about to add offerings and the T&C file step is unfamiliar, handle it before it blocks your catalog, and a Schedule management review walks your specific onboarding path.
Why Is My GSA Advantage Catalog Not Getting Found?
Because uploading a catalog and making it discoverable are two different things. Most contractor listings exist but do not surface for buyers, because the data was entered to satisfy the system rather than to match how buyers search.
The difference between a catalog that sits and one that gets found:
| Buyers find catalogs that… | Buyers skip catalogs that… |
| Use clear, buyer-language descriptions and the terms agencies actually search | Use internal part numbers and jargon no buyer types |
| Have complete, accurate fields and current pricing | Have sparse fields, gaps, or stale pricing |
| Match the SINs and categories buyers browse | Sit under the wrong or too few SINs |
| Keep catalog data and any transactional reporting consistent | Show mismatches between catalog and reported sales |
GSA Advantage and GSA eLibrary serve different buyer needs: Advantage is where buyers shop and order, eLibrary is where they research contractors and SINs. A discoverable presence means showing up usefully in both.
Our Take
Catalog management is the quietest lever in the entire Schedule, and the most neglected. Contractors will spend months chasing a Schedule award and then load a catalog in an afternoon, in internal language, and wonder why no orders come. FCP is a chance to reset that. The platform is new enough that the contractors who treat catalog data as a discoverability problem, not a data-entry chore, will out-surface competitors still managing listings the old way or following retired SIP advice. Make sure your T&C file is right, then build the catalog for how buyers actually search. That connection between compliance setup and growth outcome is exactly what GSA Verticalization™ is built to drive.
Frequently Asked Questions
Is the FAS Catalog Platform mandatory? Yes for new MAS awards. As of November 6, 2025, all new MAS contracts automatically onboard into FCP, and GSA is requiring existing contractors to migrate through a baseline modification. The legacy Schedule Input Program (SIP) is being retired.
What is the T&C file update in FCP? Starting April 6, 2026, contractors moving through FCP onboarding must update their Terms and Conditions file. It applies especially to contractors awarded after August 28, 2025, brand-new FCP users, and existing users adding offerings that require a new Baseline action.
What is the difference between FCP and SIP? FCP is GSA’s current web-based catalog management platform that publishes to GSA Advantage. SIP is the older Schedule Input Program being phased out. Most older catalog guidance refers to SIP and is now outdated.
Why is my GSA Advantage catalog not showing up to buyers? Usually because the catalog was uploaded but not optimized: descriptions use internal jargon instead of buyer language, fields are incomplete, pricing is stale, or items sit under the wrong SINs. An uploaded catalog is not the same as a discoverable one.
What is the difference between GSA Advantage and GSA eLibrary? GSA Advantage is the online store where buyers shop and place orders. GSA eLibrary is where buyers research contractors, contracts, and SINs. A strong presence means being useful in both.
Turn Your Catalog From a Checkbox Into a Channel
A catalog buyers cannot find is a Schedule that cannot sell. FCP gives you a clean reset, but only if the T&C file is right and the catalog is built for how agencies actually search, not how your internal systems label products.
A Schedule management review confirms your FCP onboarding and T&C file, then rebuilds your catalog data so your offerings surface where buyers look.

Getting awarded put you on the Schedule. Getting found is what makes it worth having.
