How Should Small Business Contractors Prepare for a GSA Multiple Award Schedule Refresh?

According to GSA’s MAS Solicitation Refreshes page, the solicitation-level SF30 is the attachment on SAM.gov that shows the overall changes for a given refresh, while the contract-level SF30 is issued through the mass modification process and shows the changes that apply to the specific contract. GSA also says the contract-level SF30 can include changes from multiple refreshes if a vendor did not accept a prior mass modification before the next refresh was issued. The October 2026 MAS Modification Guide says GSA developed detailed modification instructions, FAQs, and resources so vendors can prepare a modification package that GSA can quickly evaluate and process. The guide states that its instructions align with current solicitation proposal instructions, points contractors to the MAS Clause Applicability Matrix for clause information, and directs questions to the assigned contracting officer or contract specialist. It also says that if a contract is still under Commercial Sales Practice/Non-TDR, the vendor should use the External Modification Guide for Refresh 30.
