Talk to your books.

Atlas is real double-entry accounting — invoices, bills, payroll, bank feeds, financial statements — with something no other small-business product has: connect Claude or any AI assistant directly to your company's books. Ask questions in plain English. Get answers from your actual ledger, not guesses.

The AI can draft. Only you can post.

Atlas speaks MCP — the open standard that lets AI assistants work with real software. We're one of the first to offer MCP connections to most major AI providers: connect your assistant and it can pull your P&L, check a customer's balance, run your quarterly tax worksheet, or draft an invoice while you're on the phone.

And it works inside rules we built for accountants, not demos:

Drafts only. The AI can prepare invoices and estimates — it can never post to the ledger. Posting always takes a person.

Scoped access. You choose exactly what a connected AI can see. Payroll is off unless you explicitly turn it on.

Everything on the record. Every AI action lands in an append-only audit log — who, what, when.

Clearly labeled. Anything an AI drafted is badged as AI-drafted until a human reviews and posts it.

How a question becomes an answer

You ask A question or a task, in plain English — to Claude or any AI assistant that speaks MCP.

Atlas enforces the rules The request comes in on a scoped key — it sees only what you allowed, and every action lands in the audit log.

You post Anything it drafted waits, badged as AI-drafted, until a person reviews and posts it. Nothing reaches the ledger on its own.

Atlas API-key scopes: each grant spelled out in plain language, payroll off by default

You decide what a connected AI can see — payroll off by default.

Switching is our job, not yours.

Atlas imports what QuickBooks exports: your chart of accounts, customers, vendors, opening balances, and open invoices and bills — document by document, tied out to your closing trial balance. We run the migration with you, on a documented runbook, and you go live on a clean ledger with your history intact.

White-glove isn't an add-on tier. It's how we onboard everyone right now.

STEP 1

Export from QuickBooks

You send us the file. That's your whole job.

STEP 2

Import & tie out

Document by document, to your closing trial balance.

STEP 3

Parallel-run a cycle

Both systems, side by side, until the numbers agree.

STEP 4

Go live

A clean ledger, with your history intact.

Built for the owner who runs the books.

Atlas is for owner-operated businesses with roughly 5–50 employees. If you (or one trusted person) run the books and you're tired of fighting your software, this was built for you.

Today we run payroll for Wisconsin and Minnesota, and we add states when real customers need them — not before. If that's you, let's talk: flat pricing that makes sense — $37/month, or $75 with AI connections and payroll.

Hospitality

The motel owner

Runs the front desk and the books. Occupancy tax, payroll for housekeeping, one person doing it all.

Services

The service crew

Estimates that become invoices, techs on payroll, parts on purchase orders. Books done at night.

Trades

The contractor

Progress billing, 1099 subs, checks printed on Friday. Needs the numbers to tie out, every time.

Questions people ask.

Can I connect Claude or another AI assistant to my accounting software?

Yes — with Atlas. Atlas speaks MCP (Model Context Protocol), the open standard that lets AI assistants work with real software. Connect Claude or any MCP-capable assistant and it can pull your P&L, check a customer's balance, run your quarterly sales-tax worksheet, or draft an invoice — from your actual ledger, not guesses. To our knowledge, Atlas is the first small-business accounting product to offer this.

What is MCP in accounting software?

MCP (Model Context Protocol) is an open standard that lets AI assistants like Claude and ChatGPT connect to software through secure, permissioned tools. In Atlas, an MCP connection lets your AI assistant read reports and draft documents in your books under scoped permissions, with every action recorded in an append-only audit log.

Is it safe to let an AI work with my books?

In Atlas, the AI can never post to the general ledger — it can only draft. Every AI-drafted document is clearly badged and waits for a person to review and post it. Access is scoped (payroll is off unless you explicitly allow it), every AI action is recorded in an append-only audit log, and posted entries are immutable.

Can Atlas replace QuickBooks?

Yes. Atlas is a full double-entry accounting system: invoicing with sales tax, estimates, bills and approvals, check printing, bank feeds and reconciliation, native payroll, and real financial statements. Atlas imports what QuickBooks exports — chart of accounts, customers, vendors, opening balances, and open invoices and bills — and migration is run with you on a documented runbook, tied out to your closing trial balance.

Does Atlas include payroll?

Yes, natively — no third-party add-on. Federal and state withholding are computed from the IRS and state formulas and verified to the cent against the official worked examples. Atlas supports Wisconsin and Minnesota payroll today, with pre-tax benefits, printed paychecks with full stubs, and quarterly 941 / annual 940 worksheets. More states are added as customers need them.

How much does Atlas cost?

$37 per company per month for the full books, or $75 per month with MCP AI connections and native payroll included. Flat pricing, no per-user fees, white-glove QuickBooks migration on every plan. See pricing.
