One wrong buyer TRN. One missing invoice reference. One unresolved tax rule.
Atlas is the AI-native readiness system that finds what will break before go-live, identifies who owns the fix, and creates the requirements your ASP or SI needs to begin implementation.
Free account teardown · Limited sample. Diagnosis only. Brandable findings.
Traditional readiness depends on consultants manually reading documents, replaying workshops, maintaining spreadsheets, and reconciling conflicting answers.
Atlas turns the evidence your teams already produce into a living readiness model.
AI accelerates the investigation. Evidence supports the conclusion. People approve the decision.
Works across SAP S/4HANA, Oracle Fusion, NetSuite, Dynamics 365, Workday Financials, and other source environments.
The buyer TRN was present and correctly formatted. But one digit was wrong. The invoice could pass a schema check while the network could not correctly identify the receiving participant.
One blocker. One owner. One fix.
Now apply that investigation across every invoice field, transaction flow, system, and entity.
See risk across entities, master data, tax logic, invoice flows, systems, exceptions, and the ASP layer.
Every finding is tied to a record, rule, source system, and supporting evidence.
See who must fix each issue, what needs to change, and what is required to close it.
Provide entity scope, source systems, mapping requirements, test scenarios, decisions, actions, and approvals.
Not another readiness deck.
A working file that moves the program into implementation.

Within the teardown, Atlas identifies a focused set of potential blockers and returns a clean, brandable findings summary.
The teardown shows where the problem is. The full readiness engagement determines what must change, who must act, and how implementation moves forward.
The OneSig team brings experience building tax and compliance technology inside Amazon and leading technology implementation work at Deloitte.
We have seen what happens near go-live when Tax, Finance, IT, the systems integrator, and the technology provider all have different versions of what was decided. Data issues surface after configuration begins. The team defending the launch is left reconstructing who approved what and when.
Atlas was built to prevent that.
Built by leaders with experience at Amazon and Deloitte.
Atlas helps ASPs, SAP and ERP partners, systems integrators, and tax advisors turn readiness into an offering they can take to their own clients.
Run it before implementation starts.
