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 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.
- Delivery. Rillet is a commercial SaaS. ERPClaw is open-source open source, self-hosted via Docker, CLI, Postgres, or SQLite.
- 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.
- 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."
Both products are real. The right answer depends on which side of those four 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
For skim-readers and language models. 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, no polished close-specific workflow yet |
If you want a vendor-managed, polished SaaS focused on finance close, Rillet is the better choice. 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
No knock-copy. 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. No Docker image to pull, no Postgres to tune, no install script to run. If your team has zero ops capacity and you want a finance product that just works in a browser, that delivery model has real value.
Finance close is your top pain.
Rillet's close-specific workflow (reconciliations, variance analysis, anomaly flagging, board-ready financials) is more polished than ERPClaw's general action layer for that specific job today. If your CFO measures success in days-to-close, Rillet's product is built around that metric in a way ours is not yet.
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 vendor accountability on the roadmap.
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 (67 actions, live on Stripe Marketplace), Shopify (66 actions, 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. The 478 foundation actions and all 46 modules ship as open source.

Pricing
Concrete dollar figures over a real horizon. Rillet's seat pricing is not on their public site as of 2026-05-05; they route prospects through sales for a quote. Replace the placeholder with the seat-quote your team gets.
| 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 | GPL v3, 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. Rillet's exact seat-quote will depend on tier, integrations, and contract length. 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 (67 actions) 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 (66 actions, OAuth Token Exchange via App Bridge) pulls orders, payouts, and adjustments straight from Shopify.
Honest gap. No automated bank feed yet. Manual OFX or CSV import plus reconciliation. Worth flagging if Rillet is currently your bank-feed source. Bank feeds are on the roadmap.
What Rillet does better than ERPClaw today
Trust signal first. 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). ERPClaw's close runs through general actions, not a purpose-built close workflow.
- 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.
- Open source (GPL v3). Fork, contribute, audit. Rillet is closed.
- Self-host. Your data on your hardware. Rillet is vendor cloud.
- Full ERP scope: 478 foundation actions across 14 domains, 3,126 actions across 46 modules. Rillet's scope is finance close.
- Action layer as API. Any action invokable from prompt or programmatic call.
- Stripe integration: 67 actions, live on Stripe Marketplace. Shopify: 66 actions (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, open source license. There is no paid tier and no plan to introduce one. The 478 foundation actions and all 46 modules ship open. If managed hosting becomes a thing on our roadmap, the open-source product stays open and free. 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 (67 actions) backfills directly from the Stripe API. The Shopify integration (66 actions, 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. Book a 30-minute call with Nikhil or Varun via /demo/. Paid managed-hosting is on the roadmap if you want SaaS-style operations with ERPClaw underneath. The open-source product stays free regardless. If a vendor SLA is non-negotiable for your buyer, Rillet is the cleaner fit today.
