Disconnected evidence
The technical event, the tax rule, the document and the accounting consequence live in different systems.
Armstrong Global IT presents
Griffin. The Tax Operating System for global enterprises.
Griffin turns enterprise operations into tax-correct, calculated, authorized, reconciled and auditable transactions — regardless of ERP, country or channel.

The global tax compliance problem
Tax compliance was never designed to run across disconnected systems.
The problem is not tax calculation. It is that tax operations are fragmented across ERP, procurement, commerce, master data, tax engines, middleware, authorities, accounting and audit.
Reactive exception handling
Non-compliance is found after processing, rejection, a payment block or a failed posting.
Volatile regulatory logic
Country mandates change faster than tightly coupled ERP customizations can follow.
Limited visibility
Monitoring shows that something failed. It rarely explains the tax impact or the way out.
Product evolution
From understanding a failure to operating tax compliance.
Observe
Understand where a tax flow failed and reconstruct the full transaction timeline.
Validate
Detect missing, inconsistent or non-compliant data before processing continues.
Orchestrate
Coordinate systems, validations, decisions, exceptions and reprocessing across the flow.
Recommend
Explain tax impact, identify likely root cause and propose governed remediation.
Calculate
Determine tax with governed rules, evidence and scenario intelligence.
Operate
Deliver tax compliance and statutory reporting as a service.
What makes Griffin different
Technical logs tell you something failed. Griffin explains the tax consequence.
Generic observability says
HTTP 400 returned by the integration endpoint.
Griffin says
Supplier invoice blocked. Ariba cXML tax data conflicts with the SAP tax code and TAXBRA determination. Posting and payment are at risk.
That difference — between an error and an explanation — is the product.
In development · Brazil
SAP and Ariba accounts payable, with tax-flow diagnosis.
Griffin is being built around a high-friction reality: supplier invoices crossing Ariba, SAP and Brazilian tax localization.
Capture
Correlate Ariba cXML, SAP invoice data, tax codes, master data and fiscal status.
Diagnose
Compare payloads and find where technical and tax semantics diverged.
Recommend
Explain business impact and present a governed remediation path.
Reprocess
Coordinate controlled retry and preserve the evidence trail.
Product architecture
Specialized modules. One operating system.
Griffin Connect
Connectivity across ERP, procurement, commerce, tax engines and authorities.
TITAN
Tax orchestration and semantic observability.
APOLLO
Master data intelligence for tax-ready data.
EAGLE
Governance, workflow and auditable tax decisions.
ORION
Global e-invoicing and statutory reporting.
RIGEL
Global trade compliance beyond domestic borders.
Griffin Tax Engine
Determination, calculation and scenario simulation.
Built for Clean Core
Preserve the ERP core. Move regulatory complexity outside it.
SAP publishes the events and data Griffin needs. Griffin performs validation, orchestration and compliance work outside the core, and governed results return to SAP with evidence and traceability.
The route to market is SAP-centric. The product architecture is not.
Why the name
Strength of the Lion. Vision of the Eagle. Precision of Armstrong.
In mythology, the Griffin guards treasure — the union of the lion's strength and the eagle's far sight. Armstrong's own manifesto rests on the same pair, so the product carries the company's conviction in its name.
In a data ecosystem, the most valuable treasure is trust. Traditional tax tools were built to solve isolated parts of the problem. Griffin was designed to solve the structural one.
