One contract across five controlled phases

The runtime is a source-derived superset of the canonical target.

Ledger & platform

Tenant setup, journals, approvals, reports, webhooks, audit, and usage.

GAAP operations

AP, AR, cash, payroll, assets, revenue schedules, and close controls.

Job cost & GovCon

Projects, contracts, CLINs, WBS nodes, cost pools, and indirect rates.

AI & controls

Evidence-bearing suggestions with explicit approve and reject boundaries.

Tax & year-end

Tax packages, report snapshots, filing gates, and access evidence.
