Connecting Arvexi to your ERP: a technical guide

A lease accounting platform is only as valuable as its connection to the rest of your financial systems.

If journal entries have to be manually exported, reformatted, and uploaded to your ERP, you have not eliminated the manual work. You have just moved it. The real value comes when the data flows automatically - from lease event to journal entry to general ledger - without anyone touching a spreadsheet in between.

This guide covers the integration architecture, the setup process for common ERP systems, and the things that matter most for keeping the connection healthy over time.

Integration architecture

Arvexi's ERP integration layer is built on a REST API that supports both push and pull patterns. Journal entries generated during the close can be pushed to your ERP automatically, or your ERP can pull them on a schedule. The architecture supports three modes:

Direct API integration. Arvexi connects directly to your ERP's API to post journal entries, retrieve chart of accounts data, and sync entity structures. This is the preferred approach for cloud-based ERPs like NetSuite, Sage Intacct, and SAP S/4HANA Cloud.

File-based integration. For on-premise ERPs or systems with limited API access, Arvexi generates journal entry files in the format your ERP expects - CSV, XML, or a proprietary format - delivered via SFTP, cloud storage, or manual download.

Middleware integration. For organizations using platforms like Workato, MuleSoft, or Boomi, Arvexi provides a well-documented API that these platforms can connect to as a source system.

Regardless of the mode, every integration includes a mapping layer that translates Arvexi's output into your ERP's structure: GL account numbers, department codes, entity identifiers, and currency designations.

Setting up common ERP integrations

The setup process varies by ERP but follows a consistent pattern. Configure the account mapping. Establish credentials and test connectivity. Run a parallel period where entries are generated in both the old process and the new integration to verify accuracy.

Key considerations for the most common systems:

NetSuite. Arvexi connects via SuiteScript RESTlets or NetSuite's REST API. Journal entries post as standard records with subsidiary, department, class, and location dimensions. Multi-subsidiary configurations are fully supported with entity-specific mappings.

SAP. Integration targets SAP's BAPI or OData interfaces. Arvexi maps to company codes, GL accounts, cost centers, and profit centers. For SAP S/4HANA, the Journal Entry API provides direct posting capability.

Sage Intacct. Arvexi uses Sage Intacct's Web Services API to post journal entries with full dimensional support - locations, departments, and user-defined dimensions. Multi-entity configurations map Arvexi entities to Intacct entity IDs.

Microsoft Dynamics. Integration via the Business Central or Finance and Operations APIs, supporting journal entry posting with financial dimensions and intercompany journal support.

Keeping the integration healthy

Once the integration is live, ongoing maintenance is minimal but important.

Monitor the integration dashboard for failed postings. These typically result from GL account changes in the ERP that have not been reflected in the mapping configuration. Set up alerts for failures so they are caught immediately, not discovered during the close.

Review the account mapping quarterly to ensure it reflects any chart of accounts changes, new entities, or structural reorganizations. A healthy integration runs silently in the background - the only time your team should notice it is when reviewing the confirmation that entries posted successfully.
