Acumatica is one of the fastest-growing cloud ERPs in the mid-market - built for manufacturing, distribution, construction, and professional services companies that need modern multi-entity ERP capabilities. Its REST-first API architecture makes it more accessible to integration than many legacy ERPs. But accessible architecture is not the same as an autonomous AI finance layer. That is what ChatFin provides.

ChatFin connects Claude to Acumatica via Model Context Protocol. Once connected, Claude agents understand your Acumatica data - GL structure, business units, project accounts, multi-branch setup - and can automate AP, AR, reconciliation, accruals, and close workflows running continuously against live Acumatica data. Not exports. Not batch syncs. Live.

How ChatFin Connects Claude to Acumatica

Acumatica's REST API is the foundation of ChatFin's integration. ChatFin builds a Model Context Protocol server on top of the Acumatica REST API, exposing Acumatica's financial data as structured, business-meaningful objects that Claude AI agents can query and act on.

Acumatica REST API connection: ChatFin connects via Acumatica's native REST API. No add-on, no customisation, no Acumatica ISV installation required.
MCP server layer: ChatFin's MCP server exposes Acumatica GL, AP, AR, inventory, and project data as structured objects accessible to Claude. Agents query financial data in natural language without needing to know Acumatica's internal schema.
Permission-aware access: ChatFin connects via an Acumatica service account and respects role-based permissions. Agents only access data and modules the connected account is authorised for.
Multi-entity handling: Acumatica's multi-company and multi-branch structure is natively supported. ChatFin agents can operate across entities simultaneously for consolidated views and intercompany reconciliation.
Write-back via REST API: Agents create journal entries, AP bills, AR applications, and other Acumatica documents through the REST API - triggering Acumatica's standard business logic and posting rules.

What is left for your team

Once the automatable Acumatica work is handled, your team is left with the judgment calls: the disputed invoice, the odd accrual, the entity that closed late.

You're only doing things that, say, AI can't do if you're going to automate processes.

Dave Sackett, on the AgentCFO podcast

Staff and train for that residual work. It is a different job from the one the team is doing now.
