The City and County of San Francisco closed its fiscal year on June 30, 2025. Since the City uses a Modified Accrual method, we need our Suppliers’ full cooperation for accurate and complete reporting of SFPUC expenditures. The Controller’s Office has requested that we follow their fiscal year-end sequencing timeline. To comply with this request, the SFPUC has established the following critical date:

• 07/29/25 – Contractors/Consultants/Suppliers must submit charges for work performed through June 30, 2025 either as an invoice in SOLIS or as an estimate to PPU@sfwater.org. The method of estimating will need to be included for audit trail purposes. Please comply with this request as otherwise your payments will be delayed.
