Variable-Consideration Policy Engine & Schedule Rev
1 spreadsheet hazard consolidates into 5 software modules, 3 source integrations, and 2 deterministic controls.
What the selected hazards have in common
Every component below traces to at least one selected hazard. No timelines or savings figures are estimated; measurable outcomes require your baseline data.
ASC 606 variable-consideration rules sit in a policy tab beside the deferred-revenue waterfall, so a concession or rebate is typed onto recognized revenue after the period has already posted.
Period Schedule Engine resolves 1 of 1 selected hazards and should be built first after source systems are connected.
One spreadsheet pipeline, several failure points
The selected hazards are placed on the stage of the manual workflow where they do their damage. Sources on the left arrive as exports today.
- ERP / General LedgerTrial balance and subledger CSV exports
- Billing / Subscription SystemInvoice and payment exports
- Contract RepositoryExecuted PDFs in shared drives; terms retyped by hand
Variable-Consideration Policy Engine & Schedule Rev
A single system replaces the workbook. Shared modules are deduplicated across hazards; each card shows how many of the selected hazards it resolves.
What each component does, and what it needs
Modules are reusable across hazards. Inputs, outputs, enforced controls, and the point where a person still decides are listed for each.
Integration & Ingestion Layer
Pulls transactions, balances, and master records directly from source-system APIs and file feeds, replacing every manual export.
- Scheduled and webhook-driven API pulls
- Idempotent loads keyed on source record IDs
- Schema validation on every payload
- Read credentials for each source system
- Field mapping per source
- Normalized transaction and master-data tables with source lineage
Period Schedule Engine
Generates amortization, recognition, accrual, and renewal schedules from contract terms and posts them period by period.
- Contract-term and service-period driven schedules
- Versioned schedule revisions on amendment
- Cut-off and reversal handling at period close
- Contract terms and dates
- Invoice and billing events
- Fiscal calendar
- Scheduled entries and remaining-balance rollforwards
- Consideration assertion: a variable-consideration adjustment cannot post unless it cites the policy version and the revised schedule still equals remaining consideration.
- Policy version: a restatement cites the variable-consideration rule in force on the modification date.
Rules & Assertion Engine
Evaluates deterministic control rules on every record before it can proceed, so a failed assertion blocks the transaction instead of a person catching it later.
- Versioned rule definitions with effective dates
- Balance, threshold, and completeness assertions
- Pass/fail evidence stored per record
- Normalized records
- Policy thresholds and limits
- Assertion results attached to each record
Automated Ledger Posting
Posts balanced, validated entries to the ERP through its API so nothing is retyped and every entry carries its source lineage.
- Balanced double-entry generation
- Idempotent posting with duplicate suppression
- Subledger-to-GL tie-out on every batch
- Assertion-passed records
- Chart of accounts and mapping rules
- ERP journal entries with source references
Immutable Audit Log
Records every load, rule evaluation, approval, and posting in an append-only log so auditors can trace any figure to who did what and when.
- Append-only event history
- Hash-chained records
- Evidence export for external audit
- Events from every other module
- Audit-ready evidence trail
Traceability from hazard to automated control
Each selected hazard maps to the module that resolves it, the deterministic rule that replaces the manual check, and the result once the rule is enforced.
| Hazard | Software module | Automated control | Result |
|---|---|---|---|
#122Manual tracking of ASC 606 variable-consideration adjustments | Period Schedule Engine | Consideration assertion: a variable-consideration adjustment cannot post unless it cites the policy version and the revised schedule still equals remaining consideration. Policy version: a restatement cites the variable-consideration rule in force on the modification date. | Variable-consideration adjustments revise the ASC 606 schedule before revenue restates. |
Dependency order, not a calendar
Phases follow module dependencies: nothing downstream is built before the data it needs is flowing. Durations depend on your systems and are scoped in the diagnostic.

Immutable Audit Log
Human approval points the system preserves
Deterministic software removes re-keying and eyeballing. It does not remove judgment; these are the decisions that stay with your team.
- Integration & Ingestion Layer: Approving new source connections and field mappings.
- Period Schedule Engine: Approving schedule revisions triggered by contract amendments.
- Rules & Assertion Engine: Changing a rule or threshold requires a documented approval.
- Automated Ledger Posting: Period lock and close sign-off remain manual approvals.
- Immutable Audit Log: Auditors and controllers read the log; no one edits it.
