The full ERP
The AI-native ERP. Run your whole business in plain language.
Free forever, self-hosted, PostgreSQL or SQLite. You say what you want done. Deterministic accounting code does it, and every posting passes a 12-step validation before it touches the ledger. The AI decides what you meant. It never decides what the books say.
What "in plain language" actually means
Not a chatbot bolted onto menus. The request is the interface, and the result is a posting in a double-entry ledger.
"Invoice Acme for the March retainer, 4,500 dollars, due in 30 days."
A real invoice posts to a real ledger, numbered, dated, and aged from today.
"What did we actually make on the Henderson job?"
Revenue minus every cost tagged to that job, from the books, not from a spreadsheet copy.
"Hold 40 of the blue chairs for this order."
A hard reservation nobody else can quietly consume, refused up front if the stock is not there.
"Import the January bank statement and match it to open invoices."
Statement lines land, match themselves where they can, and queue the rest for your call.
"Bill this client for exactly the usage they racked up this month."
Usage rated, invoices generated, books posted: any pricing shape you can describe in a sentence.
"Show me everything we know about this customer."
Their deals, invoices, payments, and history, pulled from one database, because it is all one system.
One system of record, not a stack of slices
Every major business function, one install, one database, one place the truth lives. Nothing is a paid add-on, because nothing here is paid.
Money
Accounting, invoicing, bills, payments, bank statement import, multi-entity consolidation, and reports that split by department, project, or any label you run the business on.
Things
Inventory with hard reservations, putaway routing, guided pick lists, item substitutes, manufacturing with work orders and subcontracting, and honest landed costs.
People and deals
Built-in Sales from first lead to closed order: contacts, follow-up tasks, custom pipeline stages, saved views, and search across every sales record.
The awkward rest
Purchasing, billing any pricing shape you can describe, tax, HR, payroll, support, and the industry editions that install when you say what your business is.
PostgreSQL or SQLite. Your call, same code.
SQLite is the zero-setup default, which is why the install takes minutes. PostgreSQL is a first-class backend for teams that already run it, not a fallback and not an upgrade fee. The same code runs on either, and choosing between them is a configuration setting, not a code change.
Free forever is the architecture, not a promo
Open source under Free & Open Source, self-hosted on your own machine, with your books in a database you can open yourself. There is no free tier that expires, no per-seat meter, and no export ransom, because the business model is not your data. Paid managed hosting, where we run it for you, is available by request through the pricing page; the software itself stays $0.
Your choice of AI model, with the receipt
ERPClaw does not depend on any one AI model. In production it has run through Claude Opus 4.8, Kimi K2.6, Gemini 3.5 Flash, and Codex GPT-5.5, all on the OpenClaw platform, without a change to a single module.
That works because no module was ever trained, fine-tuned, or prompt-engineered for a particular model. Each module describes its actions in a plain manifest, and any model that can call tools reads the same manifest. The model interprets your request; the module's own code does the work, and the accounting checks decide what posts. A weaker model can misread a request, but it cannot post an entry that fails those checks, whichever model you picked.
Why it matters to a business: AI models change prices, get retired, and get overtaken by newer ones. If a product's accuracy depends on one model, you inherit that vendor's roadmap. With ERPClaw, switching models is a setting on the AI side, not a migration, and your books, modules, and history stay exactly where they are.
The longer version: model independence, with the receipt.
