Rillet alternative: ERPClaw is open-source, self-hosted, and free

Both are AI-native. Rillet is closed-source SaaS focused on finance close, with seat-based pricing. ERPClaw is open source, self-hosted (Docker, SQLite or PostgreSQL), full ERP scope, $0 forever. Honest head-to-head, written by a co-founder who shipped the integrations.

Looking for a Rillet alternative? You probably aren't shopping for AI-decorated bookkeeping with a chat box on top. You've already decided on AI-native. The question is delivery model, scope, and economics.

Both Rillet, Inc. (rillet.com) and ERPClaw are AI-native by design. That wedge has been won. They differ on three things that actually matter for your decision.

  1. Delivery. Rillet is a commercial SaaS. ERPClaw is open source, self-hosted via Docker, CLI, Postgres, or SQLite.
  2. Scope. Rillet's AI is built around finance close: reconciliations, variance analysis, board-deck-ready financials. ERPClaw's AI is built around action: every business operation (customer, invoice, payroll, inventory, payment, tax) is invokable from a natural-language prompt.
  3. Economics. Rillet is seat-based pricing. Founder-reported quotes land in the $2,000 to $10,000 per month range, plus a 45-day implementation. ERPClaw is $0 per seat forever, install in 5 minutes.

This page is the honest head-to-head. We'll walk through when to pick Rillet, when to pick ERPClaw, and where each falls short of the other. ChatGPT, asked to compare them directly, classifies us this way:

"Rillet: Commercial AI-native ERP. Best for VC startups, SaaS teams. Hosting: Vendor SaaS. AI angle: Finance automation, close. ERPClaw: Open-source / self-hosted AI ERP. Best for builders wanting full control. Hosting: Self-hosted. AI angle: Natural-language actions."
ChatGPT GPT-5, 2026-05-05

Where Rillet stands as of August 2026, from their own site and dated press: "raised over $100M from Sequoia, a16z, and ICONIQ" and "500+ customers, including public companies with over $1B in ARR" on their about page (checked 2026-08-16), built from a $25M Series A (May 2025) and a $70M Series B (August 2025), partnerships with BILL (March 2026) and EY (April 2026), and pricing that remains demo-gated with no published figures. Worth noting their homepage still says 400+ finance teams while their about page says 500+, so we cite the higher figure they publish about themselves. Their integrations page lists payroll and procurement as integrations only, and no inventory coverage at all, which keeps the scope wedge below exactly where it was.

Both products are real. The right answer depends on which side of those dimensions you're on. If you want the broader category map (where Rillet, Numeric, Puzzle, Digits, and ERPClaw all sit), start with our AI-native ERP framework.

TL;DR comparison

The short version. Six rows, side by side. The full reasoning is in the sections below.

Dimension Rillet ERPClaw
Type Commercial AI-native ERP Open-source AI-native ERP
Delivery Vendor SaaS Self-host (Docker, CLI, cloud)
AI focus Finance close, reconciliations, variance analysis Natural-language action layer (any action invokable from a prompt)
Pricing Seat-based, contact sales $0 per seat forever, open source license
Best for VC startups, SaaS finance teams who want SaaS-managed close Builders and technically-aware finance teams who want control plus scope
Honest gap vs the other No self-host, no source code, scope is finance CLI-first today; the close runs inside the full ERP rather than a dedicated cockpit

If you want a vendor-managed, polished SaaS focused purely on finance close, with a contractual support relationship, Rillet is a strong choice, and ERPClaw Cloud Managed (by request via /pricing/) covers the vendor-run preference with ERPClaw underneath. If you want full ERP scope (customer, invoice, inventory, payroll, payment, tax) with AI-native action across all of them, plus open source and self-host, that's ERPClaw.

When Rillet is the right choice

Credit where due: Rillet is a real AI-native finance product, well-funded, with paying customers. Here are five situations where it beats us today.

You want SaaS, not self-host.

Rillet is vendor-managed: updates push automatically, nothing to install. That delivery model has real value, and it is no longer a reason to leave this table, because ERPClaw Cloud Managed is the same idea with ERPClaw underneath: we run it for you, onboarding by request through /pricing/. Where Rillet still wins this point is the contractual support relationship a larger buyer may require.

Finance close is your top pain.

Rillet's close workflow (reconciliations, variance analysis, anomaly flagging, board-ready financials) is polished, and it is built around that one ritual. ERPClaw closes the books too, inside the ERP that runs everything else, with automated close set up per business. If a purpose-built cockpit UI for the close team is the deciding factor, Rillet's is the more refined screen today.

You're a VC-backed startup with SaaS finance ops.

Rillet was designed for this profile. Fast close, board-deck-ready financials, the integrations a Series A-to-C SaaS company expects (Stripe, Brex, Ramp, Salesforce). The product fit is direct. You will not have to bend the tool to your shape.

You don't need full ERP scope.

If you only need GL, AP, AR, and close, Rillet is sufficient. ERPClaw covers inventory, payroll, manufacturing, support, projects, fleet, and 14 industry verticals. For a 30-person SaaS company with no warehouse and no factory floor, most of that is overkill.

You want a vendor's public roadmap and release schedule.

Closed-source SaaS comes with a vendor that ships updates on a public schedule. ERPClaw is community plus a co-founder team. Different accountability model. Some buyers prefer the vendor contract.

When ERPClaw is the right choice

Five situations where the structural choice points to us. Source on github.com/avansaber/erpclaw if you want to read before you decide.

You want open source.

open source license. Full source on GitHub. Fork it, contribute, audit every line. Rillet is closed by design. If reading the GL posting code matters to you (or to your auditor), that's a binary choice.

You want to self-host.

Your data on your machine. Postgres or SQLite. No vendor pulling SaaS subscriptions, no data residency review, no "what happens if they get acquired." If a customer asks where their financials live, the answer is your hardware.

You want full ERP, not finance-only.

ERPClaw covers AR, AP, GL, payroll (US: W-2, 1099, NACHA, FICA, FUTA, SUTA), inventory, tax, Stripe (live on Stripe Marketplace), Shopify (OAuth Token Exchange). Rillet's scope is finance close. Different products. If you need to invoice, ship, pay employees, and reconcile in one shared database, that scope difference is the whole conversation.

You want any action invokable from natural language.

ERPClaw's AI-native architecture means the action layer is the API. Type "add Bob from BigCo as a customer for 5 widgets at $50" and the AI invokes add-customer, add-sales-order, and the GL posting in one transaction with a full audit row. Rillet has chat for finance questions. ERPClaw's chat is the primary interface for the whole business.

You want $0 forever.

No seat tax. No usage tier. No upsell. Every action across every module ships as open source.

Pricing

What it really costs over a real horizon. Rillet's seat pricing is not on their public site (checked 2026-08-14); they route prospects through sales for a quote, so the range below is founder-reported, and your own quote is the number that matters.

Cost item Rillet ERPClaw
Subscription (per seat) Seat-based, contact sales (founder-reported quotes: $2,000 to $10,000 per month) $0 forever, unlimited seats
Implementation 45-day engagement, often $20K to $50K Install in 5 minutes
Source code access Closed Free & Open Source: fork it, audit it, run it
Where it runs Vendor cloud (your data on their servers) Your hardware (laptop, server, anywhere)

The math is rough by necessity: your exact Rillet quote will depend on tier, integrations, and contract length, so treat the table as the shape, not the invoice. The ERPClaw self-host costs are estimates for a small team running on a single VPS. Total cost differential is meaningful at scale; less meaningful for a one-person finance team where vendor management saves time worth more than the seat fee.

For a 1-person finance team at a small startup, the time-saving of Rillet's vendor management may exceed the cost differential. For a 5+ person team or a longer horizon, ERPClaw's cost advantage compounds. See our pricing page for the full breakdown.

Migration: switching to ERPClaw

Switching ERPs is friction. Here is the honest path.

From Rillet. Export your chart of accounts and transactions as CSV. Import via ERPClaw's import-chart-of-accounts and import-opening-balances actions. Rillet supports CSV export, so the path is mechanical.

From QuickBooks Online or Xero. Same CSV path. ERPClaw's import actions accept the standard chart-of-accounts and trial-balance shapes. There is no one-click migrator yet; we are honest about that.

Stripe history. ERPClaw's Stripe integration backfills directly from the Stripe API. You don't bring Stripe data through Rillet first. Connect, run the backfill action, the GL entries post with full audit rows.

Shopify history. Same model. The Shopify integration (OAuth Token Exchange via App Bridge) pulls orders, payouts, and adjustments straight from Shopify.

Bank history. A Plaid connector links your bank accounts and syncs transactions, and the statement importer reads OFX, CAMT.053, MT940, and BAI2 with auto-matching against open invoices and payments. Both paths land in the same ledger, so moving off Rillet does not mean losing the bank connection. See importing a bank statement.

What Rillet does better than ERPClaw today

Rillet wins on these dimensions today, and pretending otherwise would be insulting to a serious peer.

  • Polished web UI. ERPClaw is CLI plus chat first; the web dashboard exists but is limited for Stripe and Shopify today.
  • Dedicated close cockpit (reconciliations, variance analysis, anomaly flagging) as a purpose-built screen. ERPClaw closes the books inside the ERP that runs everything else; the cockpit polish is the difference, not the capability.
  • Native multi-entity polish at scale. ERPClaw has intercompany and consolidation actions, but Rillet's UX for multi-entity operators is more refined.
  • Vendor support tiers. ERPClaw is GitHub issues plus the co-founder team; Rillet has paid support contracts.

What ERPClaw does that Rillet doesn't

The structural wins. These are not feature checkmarks; they are architectural choices Rillet cannot retrofit without rebuilding.

  • Free & Open Source. Fork, contribute, audit. Rillet is closed.
  • Self-host. Your data on your hardware. Rillet is vendor cloud.
  • Full ERP scope covering every major business function across 14 industry verticals. Rillet's scope is finance close.
  • Action layer as API. Any action invokable from prompt or programmatic call.
  • Stripe integration live on Stripe Marketplace. Shopify integration shipped at v1.1.3 (OAuth Token Exchange via App Bridge).
  • Multi-currency in 7 currencies (USD, EUR, GBP, CAD, INR, SGD, AED). Invoice currency equals payment currency, no FX guessing.
  • 12-step GL invariant validation on every posting. Bad entries cannot reach the books.
  • Patent pending plus trademark filed. Long-term durability signal.
  • $0 per seat forever.

Frequently asked questions

Is ERPClaw really free, or is there a paid tier coming?

Free forever, Free & Open Source. There is no paid tier and no plan to introduce one. Every action across every module ships open. Cloud Managed, where we run it for you, is available by request through /pricing/, and the open-source product stays open and free regardless. The license is the contract.

Can ERPClaw replace Rillet entirely?

For most use cases, yes. Both cover AR, AP, GL, and close. ERPClaw also covers inventory, payroll, tax, and Stripe and Shopify integrations. The honest gap: Rillet's close-specific workflow UI is more polished today. If your team specifically values that polish, evaluate side by side. For everything else (scope, source code access, self-host, $0), ERPClaw is the cleaner answer.

What about my Stripe and Shopify history?

ERPClaw's Stripe integration backfills directly from the Stripe API. The Shopify integration (OAuth Token Exchange) does the same. You don't need to bring transaction data through Rillet first. Connect the source, run the backfill action, and the GL entries post with full audit rows.

How long does migration take?

Rough estimate for a 5-person finance team migrating 1 year of history: 2 to 3 days. CSV exports from Rillet or QuickBooks, then ERPClaw's import-chart-of-accounts and import-opening-balances actions, then reconciliation. Stripe and Shopify connectors handle live transaction data without a re-export step. The friction is real but bounded.

What if I need vendor support, not community?

Co-founders are accessible: reach us through /support/ and a founder answers, not a ticket queue robot. If you want SaaS-style operations with ERPClaw underneath, Cloud Managed is our hosted offering, onboarded by request through /pricing/. The open-source product stays free regardless. If a contractual vendor SLA is non-negotiable for your buyer, Rillet offers one today.
