AI inventory connected to your books, not bolted on
Cin7, Katana, and Inflow added forecasting AI to a forms-and-workflows inventory product. ERPClaw is AI-native: the agent posts stock-ledger entries directly with FIFO or weighted-average costing, in the same transaction as the GL entry. Open source, self-hosted, $0 forever.
What is AI inventory management?
AI inventory management is inventory software where an AI agent reads stock levels, posts movements, computes costs, and proposes actions. AI-native inventory has the agent at the database layer with constitutional invariants enforcing inventory plus GL parity. AI-decorated inventory (most of the market) bolts a forecasting model onto a 1990s ERP. ERPClaw is AI-native and connects inventory to your books in a single shared database.

What AI inventory does in ERPClaw
Stock movements posted by an AI agent
When a Shopify order ships, the AI posts the stock-ledger entry (SLE) and the GL entry in the same transaction. Inventory and accounting move in lockstep. No nightly batch sync, no reconciliation drift.
FIFO and weighted-average costing
Both costing methods are first-class. Pick per-warehouse or per-item. The agent computes cost-of-goods-sold using the correct method on every shipment with full audit trail.
Reorder points and stock alerts
Set reorder points on items; the agent monitors stock levels and creates purchase orders or alerts your team when inventory falls below threshold. No separate forecasting SaaS subscription.
Multi-warehouse stock with reservations
Multiple warehouses, transfer orders between them, reservations against sales orders. The shared database means a sales order in one warehouse and a manufacturing work order in another see the same authoritative stock level.
Bill of materials and work orders
BOM definition with sub-assemblies, work orders that consume raw materials and produce finished goods. The agent posts work-in-progress and finished-goods movements correctly for accountants and operators.
Cycle counts and physical inventory
The agent runs cycle counts on a schedule, surfaces variances, and posts adjustments with reason codes. Physical inventory at year-end reconciles against the perpetual SLE without separate reconciliation tooling.

Frequently asked questions about AI inventory
What is AI inventory management?
AI inventory management is software where an AI agent reads stock levels, posts movements, computes costs, and proposes reorder actions on its own. AI-native inventory (like ERPClaw) integrates the agent at the database layer; AI-decorated inventory (Cin7, Katana, Inflow with AI add-ons) is a forecasting layer bolted onto a forms-and-workflows product.
Is forecasting AI the same as AI-native inventory?
No. Forecasting AI predicts demand; the human still posts stock movements through forms and approvals. AI-native inventory has the agent posting movements directly into the ledger with constitutional invariants enforcing inventory plus GL parity. Forecasting AI is a useful add-on; AI-native is a different architecture.
Can ERPClaw handle multi-channel retail (Shopify, Amazon, eBay)?
Today ERPClaw's first-party connectors are Shopify and Stripe. Amazon and eBay can be ingested via CSV or through a thin custom action defined in a SKILL.md spec. We are prioritizing first-party connectors based on user demand. For Shopify-only stores, ERPClaw covers the stack natively.
How does ERPClaw inventory compare to NetSuite for manufacturing?
NetSuite is broader at the Fortune 500 level (advanced manufacturing, work-in-progress costing, complex BOMs with sub-assemblies of sub-assemblies). ERPClaw covers SMB to mid-market manufacturing: items, warehouses, BOMs, work orders, FIFO/weighted-average costing, cycle counts, reorder points. The architectural advantage at SMB to mid-market is the AI-native action layer plus $0 forever cost.
Does ERPClaw support multi-warehouse with FIFO costing per warehouse?
Yes. Each warehouse has its own SLE; FIFO and weighted-average costing are configurable per item per warehouse. Transfer orders between warehouses post the right cost basis on each side. The shared database means reports across warehouses are accurate without batch sync.
Can the AI agent close my month-end inventory reconciliation?
Yes. The agent runs the close calendar: physical-vs-perpetual variance, work-in-progress reconciliation, COGS recalculation, period-end accruals. You review exceptions, not entries. The 23 invariant checks ensure inventory and GL stay balanced; structural drift is impossible.
Is open-source AI inventory really production-ready?
ERPClaw inventory is on the same code path as the accounting ERP serving paying Stripe Marketplace customers. 3,629 automated tests, 270 constitutional tests, immutable stock-ledger entries (cancel = reverse, never edit). The open-source advantage is observable controls; you can read the code and verify the costing logic line by line.
