Mass Modifications (Mass Mods) are government-initiated modifications that occur when a uniform change occurs under the MAS program. A prime example is a refresh to the terms and conditions of your contract.
When a Mass Mod is issued, the contract’s authorized negotiator is notified via email with instructions for how to access, read, and accept or decline the Mass Mod.
The eMod system is used to request a modification to your contract. If you need additional modification information, please visit the table of contents on the eOffer/eMod Help Center.
A modification is a change to the contractual terms of your contract. Changes can be requested by GSA or by contract holders.
