The San Francisco Controller's Office maintains a database of purchasing activity from fiscal year 2007 forward. This data is presented on the Purchasing Commodity Data report in CSV format, and represents detailed commodity-level data by purchase order. Additional lines have been added to this dataset to reconcile some document totals from the City's purchasing system to the totals from the City's accounting system in cases when the two amounts are different, which sometimes occurs due to adjustments entered into the accounting system but not the purchasing system. We have removed sensitive information from this data – this is intended to show payments made to entities providing goods and services to the City and County and to protect individuals. For example, we have removed payments to employees (reimbursements, garnishments) and jury members, revenue refunds, payments for judgments and claims, witnesses, relocation and rehousing, and a variety of human services payments. New data is added on a weekly basis.

Supplier payments represent payments to City contractors and vendors that provide goods and/or services to the City. Certain other non-supplier payee payments, which are made to parties other than traditional City contractors and vendors, are also included in this dataset, These include payments made for tax and fee refunds, rebates, settlements, etc.

The San Francisco Controller's Office maintains a database of contracts and payments made to Suppliers (vendors, contractors and grantees). The Supplier Contracts shown here include all fully executed, expenditure-only contracts, including City contracts for commodities, professional and general services, and construction from fiscal year 2018 forward, based upon the contracting departments' inputs. This data set includes both departmental and citywide contracts.

This data is presented on the Supplier Contracts report hosted at http://openbook.sfgov.org, and is also available in CSV format, which lists summary data by contract. We have removed sensitive contracts and information from this data in order to balance disclosure requirements and protected/confidential data. For example, we have removed contracts related to certain legal proceedings that are exempt from disclosure. New data is added on a weekly basis.

Revenue contracts, including concessions and rental income contracts, are not included in this data set; they are tracked in departmental subsystems and currently are not available in SF Open Book. For more information about Revenue Contracts, please contact the respective City Department that awards the contract, e.g. for Airport Concession Contracts, contact the San Francisco Airport Commission which maintains these records.

City Department spending may occur three ways: 1) from Contract to Purchase Order (i.e. a PO with an accounting Encumbrance) to Payment (i.e. an accounting Voucher), AKA On-Contract spending, 2) direct-to-Purchase Order (no contract, only a PO agreement and accounting Encumbrance) to Payment, and 3) Direct Voucher Payment (for limited one-time, non-recurring payments, e.g. a membership or a subscription). Therefore, it is helpful to use both the Supplier Contracts and Supplier Payments reports on SFOpenBook, as well as on DataSF.

The data included in the Supplier Contracts dataset reflects supplier expenditure contracts that were awarded by City Departments after 7/1/2017, the date the City & County of San Francisco implemented the PeopleSoft Financial & Procurement System, as well as the remaining not-to-exceed contract authority for all supplier expenditure contracts that were still active along with their associated purchase order (PO) available, unexpended balances as of 7/1/2017. For partially used contract authority, the Contract Award Amount only includes the portion that was unutilized and available as of 7/1/2017, unless the Contract Award Amount was updated by the department after July 1, 2017. Contracts that were expired before 7/1/2017 as well as contracts that had no remaining contracting authority from which to issue new purchase orders were not converted or loaded into PeopleSoft. For information requests regarding the latter as well as for the portion of contract of authority used prior to 7/1/2017 for otherwise unexpired contract balances that were converted and still active as of 7/1/2017, please contact the City department(s) that issued the contract.
