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.
