Phase 1A Overview
Phase 1A of the OneWA program includes replacement of the Agency Financial Reporting System (AFRS) - the state's general ledger accounting system - with a new, cloud-based enterprise resource planning (ERP) system. A complete ERP system combines business functions (finance, procurement, budget, HR, and payroll) across an organization’s main resources – its people, money, information and assets – and provides decision makers with real-time enterprise information.
Phase 1A Goals
- Improve the effectiveness of state government through the replacement of Washington's core financial system, the Agency Financial Reporting System (AFRS).
- Transform financial business processes through both innovation and improvements supported by technology.
- Continue to provide the tools and resources for agencies to develop or train and invest in the financial workforce of today and tomorrow.
Phase 1A Scope:
- Accounts payable and payments (not travel)
- Accounts receivable and invoicing
- Banking and settlements
- Centralized vendor/customer management
- Cost allocation for health & human service agencies
- Encumbrance accounting
- Financial reporting
- Fixed assets
- Interagency payments
- New foundational data model
- Purchase authority and purchase item data
- Spending plans and budget controls
Phase 1A go-live date range: October 2027 through October 2028.
What the go-live date range means:
- OneWA is planning and working toward the earliest date in the range—together.
The program schedule is currently built to support the first available go-live window (October 2027), and agency planning and support activities align to that target. - The range gives the program structured opportunities to check readiness and adjust as needed.
Built-in checkpoints allow the program and agencies to assess progress, surface risks early, and make informed, enterprise-level decisions about readiness for a given date. - Go-live dates occur within defined enterprise windows.
The available go-live windows are October, April, July, or October, and decisions about moving to a later window are made through program governance based on collective readiness.
What the go-live date range does not mean:
- It does not change the enterprise go-live approach.
Phase 1A remains a single, coordinated enterprise go-live, not a staggered or agency-by-agency deployment. - It does not mean agencies select their own go-live date.
Dates are determined at the enterprise level to ensure system stability, integration readiness, and statewide operational continuity. - It does not include January as a possible go-live window.
January is intentionally excluded due to elevated risk from HRMS and AFRS year-end processing and system changes during that period.
