Use GSIN codes to find SOSA data

GSIN codes connect all of the procurement data on Buyandsell.gc.ca, including Tenders, Standing Offers and Supply Arrangements, and Contract History. Therefore, it is helpful to know what GSIN codes align to your industry. (Browse GSIN Codes to find a code related to your industry or learn how to find GSIN codes in the Get Started with GSIN codes page.)

Knowing your GSIN code(s) can help you narrow down to information related to your industry and find the most relevant standing offer or supply arrangement.

UNSPSC to replace GSIN codes

Coming in 2019, the United Nations Standard Products and Services Code (UNSPSC) will replace the GSIN codes. There is no immediate impact to businesses or government buyers. As the transition to UNSPSC is implemented, all of the GSIN codes will be mapped to UNSPSC. This mapping between the GSIN and UNSPSC will be shared by PWGSC on Buyandsell.gc.ca as open data.

For businesses - Why use SOSA

Standing offers and supply arrangements are two methods frequently used by government departments and agencies to buy goods or services.

With SOSA, you can find potential partners from a pool of pre-qualified suppliers to fulfill requirements in Government of Canada opportunities. For instance, businesses new to selling to government can identify pre-qualified suppliers to contact about exploring possible partnerships.

You can enhance your planning by knowing the end dates of standing offers and supply arrangements in your industry to prepare for possible future opportunities. As well, you can use the listed regions of delivery to understand regional opportunities. You can also find out the department or agency PWGSC issued the standing offer or supply arrangement to understand who is buying your good or service.

For government - Why use SOSA

With SOSA, buyers have a tool to find, filter and search for information on businesses holding PWGSC standing offers and supply arrangements.

SOSA uses the information obtained from the Standing Offer Index (SOI), a government-only tool for procurement professionals. The SOI contains the full standing offer or supply arrangement procurement documents, whereas SOSA lists the tombstone data, such as supplier name, description, GSIN code, agreement number, etc.

Use SOSA before the Standing Offer Index

Some procurement professionals use SOSA before using SOI because it is easy to search, and helps them do preliminary work to find suppliers. From there, they use SOI to get the actual documentation for the standing offer or supply arrangement.
