Why this exists

Every public sector software company runs into the same bottleneck: ERP data.

Government ERP systems were not designed for modern software, AI agents, continuous audit, benchmarking, or cross-agency intelligence. Data is fragmented across tables, modules, workflows, exports, and local configurations. ThirdLine turns that complexity into a usable data layer.

✓ Partners need ERP data, but do not want to build every integration from scratch.
✓ Raw ERP data is hard to interpret without public sector finance and audit context.
✓ AI products need structured, permissioned, explainable data — not spreadsheet dumps.
✓ Accounting and advisory firms need repeatable access to audit-ready transaction populations.
The category

Plaid for public sector ERP and financial data.

ThirdLine connects to the core systems of record used by governments, standardizes the data into a common schema, enriches it with analytics and benchmarks, and delivers it to partners through API, MCP, database, or reporting-ready outputs.

01

Connect to public sector ERPs

Access data from systems like Tyler Munis, Oracle, Incode, Workday, CentralSquare, and other public sector ERPs.

02

Make the data make sense

ThirdLine maps messy tables and fields into a standard public sector ERP schema that products, models, and teams can use.

03

Deliver enriched intelligence

Go beyond raw data with analytics, classifications, audit signals, benchmarking, exception flags, and derived attributes.

How it works

From fragmented ERP systems to standardized, enriched data.

ThirdLine gives partners the infrastructure layer they need to serve governments without becoming government ERP integration experts.

The schema layer

The hard part is not just access. It is meaning.

ThirdLine does not simply move data from one place to another. We make public sector ERP data usable by converting source-specific tables into a normalized database schema with government finance context built in.

✓ Normalize vendors, employees, funds, departments, accounts, invoices, payments, requisitions, purchase orders, payroll, P-Cards, roles, and permissions.
✓ Preserve transaction-level detail while making cross-system analytics and partner products possible.
✓ Add derived attributes, classifications, exception logic, risk indicators, benchmarks, and audit-ready context.

Why now

AI-native government needs a trusted ERP data layer.

The next generation of govtech, audit, advisory, budgeting, procurement, HR, and finance applications will not be built on static exports. They will need secure, structured, context-rich access to the government’s core system of record. ThirdLine is building that layer.
