Selling What Is Not on Your Schedule: The Out-of-Scope and Open-Market Trap

Published 2026 | TIKC NewsWire

A GSA Multiple Award Schedule is one of the best sales channels in government contracting. It pre-negotiates your terms and lets agencies buy from you quickly. But a Schedule is powerful only within its boundaries, and those boundaries are exactly where contractors get into trouble. Selling items or services that are not actually on your Schedule, or quietly adding open-market products to a Schedule order as if they belonged, is a common and costly mistake. The convenience of the Schedule does not extend to things it does not cover.

What scope means on a Schedule

Your Schedule contract lists specific Special Item Numbers (SINs) and the particular products and services, at negotiated prices, that you are authorized to sell through it. That list is your scope. When an agency places a Schedule order, it is relying on the fact that what it is buying has already been vetted and priced under your contract. Anything outside that list is out of scope, and selling it through the Schedule misrepresents that the item carries the Schedule’s pre-negotiated status when it does not.

The open-market-items trap

The most frequent version of this problem is open-market items, products or services not on your Schedule that get mixed into a Schedule order. There are narrow, specific rules that allow a limited quantity of open-market items on a Schedule order, but only when strict conditions are met, including that the items are clearly identified as open market, priced fairly, and handled under the proper procedures. Slipping open-market items in without identifying them, so they ride along as if they were Schedule items, is where contractors cross the line into misrepresentation.

Why it becomes an enforcement problem

Out-of-scope selling is not just a paperwork foul. When you invoice the government for items as though they were covered by your Schedule, you are representing that they carry the Schedule’s terms, pricing, and compliance, which is a false representation if they do not. That can support False Claims Act exposure, and it undermines the pricing integrity the Schedule depends on, including the pricing and disclosure obligations that come with holding a Schedule in the first place. Oversight bodies and the GSA Inspector General pay close attention to whether Schedule sales actually match Schedule scope.

Stay in bounds, and expand the right way

The discipline is to sell through your Schedule only what is on it, and to grow your Schedule deliberately when you want to offer more. If a customer needs something outside your current SINs, you either handle it through a proper open-market procedure with full identification, or you add it to your Schedule through a modification before you sell it that way. Train your sales team on what is in scope, check orders against your awarded SINs, and never let the pressure to close a sale push an unlisted item onto a Schedule order.

What to do now

• Know your awarded SINs. Be clear on exactly what products and services your Schedule actually covers.
• Do not sell out of scope. If it is not on your Schedule, it cannot be sold as a Schedule item.
• Handle open-market items properly. Identify them clearly and follow the narrow rules, or leave them off the order.
• Modify to expand. Add new offerings to your Schedule through a contract modification before selling them that way.
• Train and check. Make sure sales staff know the scope and that orders are verified against your SINs.

A Schedule is a promise that what you sell through it has been vetted and priced, so keep every Schedule sale inside that promise. Expand the catalog the right way, and the channel stays an asset instead of a liability. Brick by brick.

FAQ

What is scope on a GSA Schedule?

The specific Special Item Numbers and the products and services, at negotiated prices, that your Schedule contract authorizes you to sell through it. Anything outside that is out of scope.

What are open-market items?

Products or services not on your Schedule. Limited quantities can sometimes be added to a Schedule order, but only when strict conditions are met, including clearly identifying them as open market.

Why is out-of-scope selling risky?

Invoicing items as though they were covered by your Schedule misrepresents that they carry the Schedule’s terms and pricing, which can support False Claims Act exposure and undermines pricing integrity.

How do I offer something not on my Schedule?

Either handle it through a proper open-market procedure with full identification, or add it to your Schedule through a contract modification before selling it that way.
