Your books, synced, searchable, and ready for AI agents.
ERP Sync connects QuickBooks Online and NetSuite to one governed ledger. It reads the documents behind your transactions, powers live reporting in Excel, and gives AI agents safe, permissioned access to do the accounting work.
ERP Sync replaces the exports, copy-paste, and document hunting that fill a month-end.
Ledger sync
QuickBooks Online and NetSuite, in one ledger
Connect a QuickBooks company or a NetSuite account and ERP Sync pulls the full history, then keeps it current with incremental change sync. Your ERP stays the system of record.
✓Full historical sync plus continuous change capture
✓Many companies, grouped by client, in one workspace
✓NetSuite OneWorld: one connection covers every subsidiary
✓Write-back through a single validated gateway
Reporting
Financial statements that tie out
Income statements and balance sheets across one company or a whole group, with drilldown from any balance to the transactions and attachments behind it.
✓Drill from a statement line to the source transaction
✓AR and AP aging reports
✓Intercompany dashboard for multi-entity groups
✓Alternate chart-of-accounts mapping for statement display
Excel add-in
Live reporting inside Excel
The ERP Sync add-in brings synced balances into the grid as formulas that refresh in place. There is nothing to export and paste.
✓Entity and period parameters that drive the whole sheet
✓One-click trend charts
✓Works with Claude in Excel to build and refresh reports
Documents
Every invoice and statement, searchable
Bring files in from Google Drive, Gmail, SharePoint, OneDrive, and Outlook. ERP Sync runs OCR on them, indexes them, and links them to the transactions they support.
✓OCR with semantic search and exact-text grep
✓Extract pages and split large PDFs
✓Attach evidence and memos directly to QuickBooks transactions
✓Tagging, moving, and organizing in shared ERP storage
AI agents
An MCP server built for accounting
Claude and other MCP-compatible agents can query the GL, pull reports, search documents, and post entries. Every call goes through tools that respect each user’s permissions.
✓GL, statements, vendors, and live QBO / NetSuite queries
✓Reads and writes gated per company and per feature
✓Agent-operated QuickBooks Bank Feeds: rules and matches
✓GL import for companies with no connected ERP
Close tools
Schedules and workflows for month-end
Prepaid and accrual schedules that match themselves to GL activity, plus review-gated workflow runs your team can open from a link.
✓Expected-activity schedules with auto-match and gap checks
✓Staged workflow runs with human review before posting
Formulas pull straight from the synced ledger. Change the entity or the period and every number in the workbook updates, so month-end reporting is a refresh instead of a rebuild.

Hand the busywork to an agent
Ask in plain English. The agent uses ERP Sync’s tools to read balances, work the bank feed, find the invoices and attach them, then tells you exactly what still needs a person.

Properties, leases, rent payments, maintenance, and a resident portal.
