# System architecture and integration model

Use this topic to understand when to use the Property Tax web application, GraphQL API, and ERP connector model.

Avalara Property Tax combines an interactive web application for day-to-day compliance operations with programmatic APIs and file connectors for enterprise system integration.

## Application interface

The web application provides the user interface for operational workflows, manual review steps, return generation, document uploads, and payment approvals.

## GraphQL API

A read-only GraphQL API enables external systems to query and synchronize data from Avalara Property Tax tenants. Key integration use cases include:

-   Synchronizing jurisdiction, assessor, and collector catalogs with master data management and enterprise resource planning systems.

-   Ingesting assessment values, liabilities, and bill details into business intelligence and financial reporting pipelines.

-   Monitoring return filing dates, statutory appeal windows, and installment due dates within enterprise compliance calendars.

-   Feeding tax bill installment schedules into treasury and accounts payable cash forecasting models.

-   Reconciling legal entity and property account hierarchies against corporate records.

## ERP and accounts payable connectors

-   Ingests fixed asset registers and asset transaction data.

-   Exports structured payment disbursement files to downstream accounting and accounts payable systems.
