Dynamic Discount Optimizer & Payment Execution Scheduler
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.
Invoice terms are reviewed on the check-preview list after the payment batch is built, so 2/10 Net 30 discounts are noticed only when someone scans due dates by eye.
Rules & Assertion 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
- Bank AccountsStatement downloads from bank portals
- Procurement / Purchase OrdersPO registry maintained in a spreadsheet
Dynamic Discount Optimizer & Payment Execution Scheduler
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
- Discount assertion: an invoice with an open prompt-pay window cannot enter a later payment run unless a documented cash or hold reason is attached.
- Cash gate: a discount payment still requires available cash above the treasury floor.
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
Approval Workflow
Enforces role-based, limit-based approvals inside the system so that decisions are recorded where the transaction lives, not in email or chat.
- Role and limit matrices
- Dual control for high-value or high-risk actions
- Signed, time-stamped approval records
- Approval policy and authorized roles
- Transactions requiring release
- Approved or rejected actions with approver identity
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 |
|---|---|---|---|
#73Manual review of customer terms and early payment discount capture | Integration & Ingestion Layer | Discount assertion: an invoice with an open prompt-pay window cannot enter a later payment run unless a documented cash or hold reason is attached. Cash gate: a discount payment still requires available cash above the treasury floor. | Prompt-pay windows are captured in the payment run, not noticed on the check preview. |
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.
- Rules & Assertion Engine: Changing a rule or threshold requires a documented approval.
- Approval Workflow: Approvers act on the request; the workflow only enforces who and how many.
- 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.
