General Instructions - Submission of Your Schedule Contract Data

What is GSA Advantage?
GSA Advantage ( is the Federal Government's premier on-line catalog, information, and ordering system which gives authorized GSA customers the ability to quickly search, compare and order those products and services which best meet their needs. Agencies may also submit request for quotes using the GSA Advantage! eBuy RFQ system which is a service of GSA Advantage.

Quick Start - Getting your catalog on GSA Advantage

  • Step 1: Read and become familiar with schedule clause 552.238-88 GSA Advantage!®. that requires participation in GSA Advantage!. Additionally, see clause I-FSS-600, Contract Price List of your Multiple Award Schedule (MAS) contract which addresses the submission of electronic catalogs. Vendors electronic catalog file must be received no later than 30 days [per I-FSS-600(a)(2)] after award. Catalogs must be submitted electronically via Electronic Data Interchange (EDI) or via the Schedule Input Program (SIP) software. For your consideration, there are also a number of companies who will prepare and submit your catalog data electronically, however, there are costs associated with this service.
  • Step 2: Register! All vendors must register with the GSA Vendor Support Center (VSC) online at or by calling toll free at 877-495-4849 (M-F 7:30-5:30 PM EST). If you use SIP it will prompt you for registration information. The VSC will provide you with a password that is required on all catalog submissions. This password is used to protect your data. VSC personnel can also provide assistance with your SIP catalog submission. All contracts must be registered with the VSC. Please note that a DUNS is required at registration. If you do not have a DUNS assigned for your company, go to where you may obtain one without charge from Dun & Bradstreet, Inc.
  • Step 3: Decide which method you will use to submit catalog information, EDI or SIP. If your organization is currently utilizing EDI for your business transactions and you wish to submit your catalog via EDI, please see Instructions for Vendors Using EDI below. If you choose to use SIP instead of EDI, please see Instructions for Vendors Using SIP
  • Step 4: Submit and update your catalog. You may submit your catalog including updates and changes 24/7. The data you submit (part numbers, description, prices, etc.) will be seen by your customers. The completeness and accuracy of the data submitted is your responsibility. Please ensure that your products and services are adequately described and remain current.

  • If you have questions concerning the preparation and submission of your electronic catalog using SIP, contact the Vendor Support Center (VSC) at 877-495-4849 (M-F 8:30-5:30 PM EST) or e-mail
  • If you have questions concerning the preparation and submission of your electronic catalog using EDI, contact our EDI Help Desk at 703-605-9444.
  • If you have general questions regarding the GSA Advantage shopping system call 877-472-3777 option 2 or e-mail:

How GSA identifies a product: GSA uniquely identifies each product using a combination of your contract number plus the manufacturer part number. Each product you submit must have a unique manufacturer part number - even if two or more manufacturers carry the exact same part number. This may require a part number modification on your part. Note: we will soon require UPC on many products so you may wish to include UPC's with your submission.

Should I submit photos with my products? Yes. Photos provide the best shopping experience for customers and give you an edge when it comes down to the customer's final purchase decision. Customers using GSA Advantage can also limit their search results to only those products with photos. Photos may be submitted via SIP or EDI. File size, resolution, and format requirements for upload can be found in the SIP Photo Guidelines and EDI Photo Guidelines

Please note the following:

  • Photos must be product specific;logos or generic images may not be submitted as a photo for a product sold.

How are purchase orders issued by GSA Advantage? GSA sends all purchase orders to MAS vendors via the GSA Purchase Order (PO) Portal web site, EDI, or XML depending upon the vendor preference and capabilities. The PO Portal web site allows you to easily view or print your GSA Advantage purchase orders, or you may download your orders in a number of formats including XLS, TXT, XML, or PDF. The PO Portal will also allow you to submit status for your orders back to customers via GSA Advantage. The PO Portal web site can be accessed only by the individual you designate using the Schedules Input Program (SIP) software or via EDI.

If you wish to receive EDI or XML purchase orders, please call 703-605-9444.

How do I provide order status to my customers? Providing order status, including shipment information, is an enforceable term and condition of your Multiple Award Schedule (MAS) contract. Providing order status to your customer must be done through GSA platforms to provide 100% transparency to support our joint customers. In order to be compliant, you must provide order status through one of the following methods on Advantage!:

  1. EDI on Advantage! For those doing EDI, the 856 transaction set documentation can be found on the VSC web site here. If you want to start providing order status via EDI, or validate whether you're providing EDI transmission sets accurately to GSA, please email
  2. Purchase Order (PO) Portal on Advantage!: The GSA Advantage! PO Portal web site allows you to conveniently provide status back on every order that is sent to you via GSA Advantage. If you would like to provide order status through the Purchase Order Portal, please see this short video on how to use PO Portal (7 minutes).
  3. XML: Contractors may also provide status back through XML and are encouraged to call our helpdesk number at 703-605-9444.

Your submission of GSA Advantage! order status via EDI/cXML or the Purchase Order Portal updates GSA and your customers. Customers are sent an email each time their order status changes, reducing the number of phone calls concerning order status. For more information on Order Status, please also review the Frequently Asked Questions (FAQs) regarding Order Status on Interact

What will my data look like in GSA Advantage? It is a good idea for you to take a look at GSA Advantage! at to get a better understanding of how the system operates and more specifically how your products and services will appear to Federal customers. Once your own catalog data is online, you should check frequently to make sure it appears as you had intended.

Can I also submit information from my authorized government price list? Vendors who submit product and pricing data are encouraged to also submit a text file containing the Customer Ordering information listed in their authorized government price list. This information will be viewable not only through GSA Advantage but also through our GSA eLibrary and eBuy web sites. Submission of your GSA contract terms and conditions will help customers make an informed buying decision.


The Schedules Input Program (SIP) software can be downloaded from the GSA Vendor Support Center. SIP is a client-side application that allows you to import/input then upload all your contract and product data for inclusion on GSA Advantage.

SIP system requirements: The SIP is a Windows based program which operates in a Windows 98 environment or greater. The minimum hardware requirement is a Pentium class PC with at least 64 MB RAM. SIP can be installed on a stand-alone PC or multi-user LAN environment.

SIP online and context sensitive help: SIP includes an online help function that can be used to assist you in the preparation of your electronic catalogs. Online help is available for each input field by simply pressing the F1 key.

Can I import my catalog data into SIP? Yes. When you install the SIP program, an Import Program is also installed which allows you to import either standard ASCII text, DBF files (versions 3.0 or greater), or MS Excel files (MS office 97 version or greater) into the SIP. Call the VSC for further information and assistance. Online help is also available within the Import Program including instructions and templates.

SIP catalog submission and Response File processing: Once you have prepared your file using SIP, you must upload it to GSA. First, click on the Communications|Create Catalog Files option. Once the create catalog process is complete, click on the Communications|Send Catalog Files option to automatically upload the file. Please note that if you later wish to replace all information you must create a replacement catalog using the Communications|Create Replacement File option.

Once your file is uploaded, it will be forwarded to the appropriate GSA/VA contracting officer (CO) for review. Once the CO has reviewed the catalog, they will send you an e-mail (or FAX, phone) stating whether the file was approved or rejected and the reasons for rejection, if applicable. A SIP response file will also be generated after the CO has reviewed your file. You must process your response file using SIP before you can send the next catalog update (you can prepare the next submission in SIP but you cannot send it until the response file has been received and processed)

The purpose of the response file is to inform you as to whether your file was approved or rejected, and to update your SIP software ensuring that both the SIP and GSA Advantage databases remain in sync. SIP will prompt you when a response file needs to be processed and will automatically retrieve and process the file. Once your response file is processed, you are free to submit further updates.

Rejected files: If your catalog file is rejected and your GSA/VA CO has not contacted you via e-mail, FAX, or phone by the time you have received your response file, please contact your CO for details as to why the file was rejected. Rejected catalogs must be resubmitted within 30 calendar days.

Temporary price reductions: Files containing temporary price reductions may be immediately loaded to GSA Advantage via EDI or SIP, after submission of a modification request via eMod. Your CO will be notified when an updated file is submitted. Note that modification requests for temporary price reductions are effective immediately upon submission and the effective date of the price reduction will reflect the date that the contractor submitted the modification via eMod.

Can I submit my MAS products or services as text? Certain schedules and SINs have been designated as either allowing or requiring a text file instead of a detailed data file. The SIP program will prompt you when this option is allowed. Please note that products and services submitted in a document cannot be ordered online but can only be viewed! Products should be submitted in a data format wherever possible.

You may send text files in .pdf, .doc, .xls, or .htm formats. Please note that the filename must not contain spaces and must reside in SIP text file subdirectory. See SIP online help for further instructions including what should be included in your text file.

Vendor Support Center: The purpose of the VSC ( is to provide assistance to vendors in the preparation and submission of their electronic catalog files. The VSC maintains a staff of personnel ready to assist you. The VSC also maintains a web site, which provides the latest versions of the SIP software, and more.

Personnel at the VSC may be reached at 877-495-4849 (M-F 8:30-5:30 PM EST), or e-mail

SIP Instructions: Use these instructions as a user manual for all your SIP questions


What is EDI and is it for me? Electronic Data Interchange or EDI, is the computer-to-computer exchange of business information using a public standard. You have several different options when it comes to using EDI to submit your catalog file. In addition to commercial off-the-shelf (COTS) packages, there are also third parties and Value Added Networks (VANs) who can assist you. If you are interested in learning more about EDI, call our EDI Help Desk at 703-605-9444.

EDI catalog submission process: Catalog data submitted to GSA via EDI transaction set 832 is first checked for EDI syntactical accuracy and then checked for data content. It is then provided to your GSA/VA contracting officer for review and approval. Once approved, vendors are notified via e-mail or FAX and catalog data is placed on-line for customer ordering via GSA Advantage. GSA will use the 824 transaction set to specify data content errors in your catalog file should your file be rejected. The 824 is sent to vendors electronically. Rejected catalogs must be resubmitted within 30 calendar days.

EDI 832 samples: Sample 832 Price/Sales Catalog transaction sets can be downloaded from the Vendor Support Center at These samples are compliant with the Federal Implementation Convention (IC), using version 3050. The 832 samples should be given to your software provider and/or Value Added Network (VAN) so that they will be able to furnish a transaction in accordance with the Federal IC's. Also included with the 832 samples is a table of expected data elements that will be edited prior to GSA/VA contracting officer review of your catalog.

Other EDI samples: You may also download samples of the 850 Purchase Order and 824 Application Advice. Additionally, the 997, Functional Acknowledgment, should be used in all appropriate cases.

Look-up tables: Look-Up Tables have been developed to assist you in the preparation of EDI transactions. These tables, which are maintained by GSA, provide valid schedule numbers, country codes, etc., and can also be downloaded from the VSC. These tables are updated as required.

How to submit your 832 Price/Sales Catalog: There are three ways in which a vendor may send in their EDI data:

  1. Vendors may use their Value Added Network/Value Added Service (VAN/VAS) provider and transmit their data through the Federal Infrastructure via the GEX (Government Electronic Exchange) at Columbus, Ohio or Ogden, Utah. The receiver IDs are as follows: The ISA07 is ZZ and the ISA08 is either DMCOGDEN or DMCCOLUMBUS, depending upon the VAN/VAS used. Your VAN/VAS provider will be able to tell you which one applies. The GS03 is 012966339 (the GSA/FAS Dun & Bradstreet (DUNS) Number).
  2. Vendors can also SFTP (Secure File Transfer Protocol) their data directly to GSA/FAS. The appropriate IP Address, Log-on ID and Password will be provided by contacting the EDI Help Desk below.
  3. A mailbox on the Sterling/IBM system is also available for those vendors whose service providers have interconnects with Sterling/IBM. Please contact the EDI Help Desk below for more information.

Contract modifications: All contract modifications and/or changes must be approved by your GSA/VA contracting officer before submitting for inclusion in GSA Advantage. Please include your modification number with your submission.

Submitting changes: Changes can be sent by line item or as an entire catalog replacement. Files containing temporary price reductions will be immediately loaded without contracting officer approval.

EDI help desk: For more information or for any questions regarding EDI, please call 703-605-9444.

Certain schedules and SINs have been designated as either allowing or requiring a text file instead of a detailed data file. EDI vendors must download the Schedule/SIN/MO Table from the Vendor Support Center at to determine which schedules or SINs allow or require a text file. Please note that products and services submitted in a text file cannot be ordered online but can only be viewed! Products should be submitted in a data format wherever possible.

Text documents submitted by EDI vendors must be created in .pdf, .doc, .xls, or .htm format and uploaded to GSA via sftp to their established sftp mailbox or by using the VSC web site. Use the Text File Upload Tool if uploading via the VSC web site. The text filename must include your contract number and the name of the file. The filename may not contain spaces. Format the filename as follows: "", where xxx is one of the formats allowed above. The document filename should be placed in the REF segment using the "TN" qualifier in the REF01 and the actual filename in the REF03.

Submitting photos: See "Can I submit photos with my product?" above for photo format and size requirements. For EDI vendors, the photo filename must be included in the 832 catalog file submission using the REF segment (2/040) with the "51" qualifier in the REF01. In order to accommodate up to an 80 character filename, use REF02 (up to 30) and then the remaining in REF03 or preferably put all of it in REF03 (80). You may repeat the REF segment up to 4 times if you wish to submit more than one photo for an item.

In order to delete a photo from Advantage, simply exclude the REF segment from the 832 catalog submission. EDI vendors will sftp their zipped photo files to their established sftp mailbox, using the naming structure ''. The .zip file will also contain an 'email.txt' file containing ONLY the email address of the person submitting the photo file. Any validation errors will be emailed back to the email address provided in the .txt file.
