Puzzle alternative: whole business, your machine, $0
Puzzle (puzzle.io) is AI accounting for startups: real automation, published pricing, books only. ERPClaw is the open-source AI-native ERP: the books plus inventory, manufacturing, purchasing, payroll, and Sales, self-hosted, free forever.

Puzzle's headline is "Accurate Books. At AI Speed.", and the company behind it is real: founded by Sasha Orloff, a $15M Series A led by General Catalyst in February 2023 and a further $30M announced that November, $50M in total. The product is a genuine double-entry system with AI categorization claiming up to 98 percent automation, aimed at venture-backed startups and the accounting firms that serve them.
The comparison comes down to three questions:
- Scope. Puzzle keeps books and stops there: no inventory, no purchasing, no payroll, no tax filing, by their own site and FAQ. ERPClaw is the whole ERP in one install.
- Custody. Puzzle is SaaS only. ERPClaw lives on your hardware with open source code.
- Economics. Puzzle publishes tiers from $25 to $300 per month with AI metered in credits. ERPClaw is $0 forever with nothing metered.

When Puzzle is the right call
You are a lean startup and want managed SaaS books this afternoon.
Puzzle's pitch is startup-shaped: connect Stripe, Mercury, Brex, Ramp, and get accurate books with burn and runway on a dashboard. If your whole operation is a SaaS product and a bank account, that focus is a feature. If the only thing keeping you off ERPClaw is not wanting to host it, Cloud Managed is our run-it-for-you option, by request through /pricing/.
Their integration list is your exact stack.
Stripe, Mercury, Brex, Ramp, Gusto, Rippling, Deel: Puzzle leads with the tools venture-backed startups already use, and meets them with published, transparent pricing, which deserves credit in a category that hides its numbers.
You want your accountant and the software from one ecosystem.
Puzzle markets to accounting firms running many startup clients, and pairs with partner firms for taxes. If you want software chosen by your bookkeeper rather than software you operate, that channel matters.
When ERPClaw is the right call
Your business is more than a bank feed and a Stripe account.
Puzzle keeps books. It does not do inventory, purchasing, payroll (it integrates Gusto and Rippling), or tax filing (partner firms), and its own site confirms the shape. ERPClaw runs stock with hard reservations, manufacturing, purchasing, payroll, and built-in Sales in the same database as the ledger.
You want $0 with no meter, not a tier ladder.
Puzzle's published pricing is honest and starts at $25 per month, with AI usage metered in credits per plan. ERPClaw does not meter the interface to the product: every plain-language operation is included, forever, at $0, because open source is the pricing model.
You want your books on your own machine.
Puzzle is SaaS only. ERPClaw is self-hosted by design, SQLite or PostgreSQL, Free & Open Source, and the ledger is a file you can open and audit yourself. For founders who consider their books a crown jewel, custody is the comparison.
You want AI-native to mean the whole company, not the close.
Both products are AI-native rather than AI-decorated, and Puzzle's categorization and reconciliation automation are real. The reach differs: ERPClaw's plain-language layer runs every operation, from 'invoice Acme for the retainer' to 'hold 40 chairs for this order,' with deterministic code posting and an invariant engine checking the books after every entry.
You plan to outgrow startup accounting without a second migration.
Startups that make it become companies with warehouses, purchase orders, and employees in several entities. Puzzle's answer at that point is another migration. ERPClaw's answer is that the ERP was already there, free, waiting for you to grow into it.
What it costs
| Item | Puzzle | ERPClaw |
|---|---|---|
| Subscription | $25 / $60 / $100 / $300 per month by tier, billed annually (published, checked 2026-08-14) | $0 forever, unlimited users |
| AI usage | Metered in AI credits per plan | Unmetered; the plain-language layer is the product |
| Source code | Closed | Free & Open Source: fork it, audit it |
| Where it runs | Their cloud only | Your hardware, your choice of database |
Common questions
Is Puzzle AI-native or AI-decorated?
AI-native for its category. Puzzle is a double-entry accounting system built around AI categorization, reconciliation, and close automation, with agent features shipping under its own brand. The honest comparison is scope and custody, not the authenticity of the AI.
Doesn't Puzzle publishing prices make them the good guys?
It genuinely does them credit; most of this category hides pricing behind demos. Their tiers run $25 to $300 per month billed annually, with AI usage metered by credits. ERPClaw's price is also published: $0, with nothing metered.
Can Puzzle run inventory or purchasing?
No. Nothing on their homepage, pricing page, or comparison pages mentions inventory, purchase orders, or warehouse capability (checked 2026-08-14). Puzzle is books for startups, and says so. ERPClaw ships the full operational stack in the same install as the books.
Does Puzzle file my taxes or run payroll?
By their own FAQ, no on both: taxes go through partner firms, payroll through integrations like Gusto and Rippling. ERPClaw ships US payroll in the ERP itself; tax filing is your accountant's job in both worlds.
Who should honestly pick Puzzle?
A venture-backed software startup with no physical operations, on Stripe and a modern bank, that wants managed SaaS books at a fair published price. That is a real fit. The moment the business grows things, people, or entities to run, the whole-business, self-hosted side of this table is ERPClaw's.
