## Financial and construction tools

A family of owner-held ledger tools sharing one double-entry design: accounting, construction cost/schedule/quality control, and (proposed) payroll. Two of the three now have real, running code — tool-accounting's ledger engine and tool-construction's cost/schedule/reporting engine; tool-payroll remains a proposed design with no code written.
A family of owner-held ledger tools sharing one double-entry design: accounting, construction cost/schedule/quality control, and payroll. All three now have real, running code — tool-accounting's ledger engine, tool-construction's cost/schedule/reporting engine, and tool-payroll's first report — though the depth of what's built varies widely across the three.

- [[financial-and-construction-tools-overview]] — How the three tools relate as one product family: the shared double-entry design, the one-way data feeds between them, and the shared free/paid architecture boundary.
- [[tool-accounting]] — A flat-file, owner-held double-entry ledger producing audit-ready financial statements; real code verified against real historical data.
- [[tool-accounting]] — A flat-file, owner-held double-entry ledger producing audit-ready financial statements; core engine and a real CLI toolchain of report binaries, verified against real historical multi-entity data.
- [[tool-construction]] — A flat-file, owner-held ledger for construction cost, schedule, and quality control; the core engine now runs as a real CLI, producing cost estimate and schedule reports for a live pilot — estimate-stage only, no console yet.
- [[tool-payroll]] — A proposed jurisdiction-aware payroll and statutory-remittance engine; 100% design today, no code written.
- [[tool-payroll]] — A jurisdiction-aware payroll and statutory-remittance engine; its first real report (a division-level Payroll Register) is built and running, but gross-to-net pay, pay frequency, and remittance remain design-only.
