Global Open Banking Multi-Entity Aggregator & Sweeping Engine
1 spreadsheet hazard consolidates into 5 software modules, 2 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.
Treasury logs into a dozen banking portals each morning and types closing balances into a positioning sheet, so the global cash picture is a snapshot assembled by hand before markets open.
Entity Resolution & Master Data Service 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.

Global Open Banking Multi-Entity Aggregator & Sweeping Engine
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
- Position assertion: the daily cash position must include a same-day balance from every registered account, and a borrowing recommendation cannot issue while any entity holds idle cash above its policy floor.
- Coverage check: the position report lists any registered account missing a same-day balance as a blocking gap.
Entity Resolution & Master Data Service
Maintains one canonical record per vendor, customer, legal entity, or contract and resolves aliases, subsidiaries, and duplicates deterministically.
- Tax ID, bank-account, and legal-name uniqueness checks
- Alias and parent-entity resolution rules
- Golden-record propagation back to ERP, procurement, and billing
- Vendor, customer, and entity masters from each system
- Contract and registration documents
- Canonical entity IDs referenced by every downstream module
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
Governed Reporting Layer
Publishes reports, board metrics, and monitoring dashboards from reconciled data only, with each figure traceable to its ledger snapshot.
- Versioned report snapshots
- Publish only from reconciled, locked data
- Drill-through from figure to source record
- Reconciled ledger and operational data
- Board packs, variance reports, and compliance dashboards
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.

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.

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.
- Entity Resolution & Master Data Service: Confirming proposed merges when two records match on some but not all identifiers.
- Rules & Assertion Engine: Changing a rule or threshold requires a documented approval.
- Governed Reporting Layer: Report release still requires reviewer sign-off; the layer prevents unreconciled figures from being publishable.
- Immutable Audit Log: Auditors and controllers read the log; no one edits it.
