What it does

Everything the books need, kept in one place

Invoices, bills, budgets, bank feeds, payroll and taxes, all tied together, so a change in one place shows up everywhere it should.

Invoicing that gets you paid

Line-item invoices, estimates that convert in one click, and a pay-by-card link that marks itself paid through Stripe.

Recurring billing on autopilot

Set a schedule once. Invoices generate themselves, and clients who save a card are charged automatically.

Bank feeds via Plaid

Connect an account, sync a year of history, and let transactions categorize themselves into a real ledger.

Cash flow you can act on

A 30-day runway, aging receivables, and a Safe-to-Spend figure that nets out unpaid bills and your tax reserve.

Real double-entry books

Chart of accounts, general ledger, trial balance, balance sheet, and income statement — generated, not hand-kept.

Taxes, without the scramble

Quarterly estimates, sales-tax tracking, 1099-NEC prep for contractors, and a read-only accountant portal at year end.

Time, mileage, and payroll

Track billable hours and miles, then pull them straight onto an invoice. Run simple payroll for a small team.

An AI CFO in the sidebar

Ask plain-language questions about your numbers. Every write it suggests waits for your confirmation.

Built to be trusted

Bank tokens encrypted at rest, per-business data isolation, closed-period guards, and a full activity log.

How it works

Up and running in an afternoon

Three steps from a blank account to books that keep themselves.

  1. 01

    Add a client, send an invoice

    Create your first invoice in under a minute. Your client gets a link they can pay by card, no account needed.

  2. 02

    Connect your bank

    Plaid pulls in transactions, CorbelBooks matches deposits to invoices and files expenses into categories.

  3. 03

    Watch the books keep themselves

    Reminders go out on schedule, the ledger stays reconciled, and your dashboard always shows what's safe to spend.

Pricing

Fixed monthly prices, no surprises

Questions

Before you start

How much does CorbelBooks cost?

Books is $25 a month, Books Pro is $49 a month, and Books + Advisor is $199 a month with a person who sets it up and checks in monthly. Books and Books Pro start with 14 days free and no card, and yearly billing gets you two months free.

Can I cancel?

Yes, any time, from your billing page. You keep access until the end of the period you've paid for, and you can download every list and report as CSV whenever you like, paid or not.

Do I need an accountant to use CorbelBooks?

No. The app keeps proper double-entry books behind the scenes so you can work in plain terms: clients, invoices, bills. When you do want an accountant involved, give them a read-only link and they see the statements they need.

How do clients pay me?

Every invoice has a private pay link. Clients pay by card through Stripe's hosted checkout, and the invoice marks itself paid when the money lands. Clients can also save a card for recurring work.

Is my bank data safe?

Bank connections go through Plaid, so we never see your bank login. The access token Plaid gives us is encrypted at rest with a key kept separate from the database, and your data is isolated to your business.

Can I bring in data from a spreadsheet or another tool?

Yes. Import clients and ledger transactions from a CSV with column mapping and a preview before anything is written. Every report and list can be exported back out as CSV.

What does the AI assistant actually do?

It answers questions about your numbers and can draft invoices or log bills for you — but it only ever proposes. Nothing is written until you click Confirm.

What about taxes?

CorbelBooks estimates quarterly income tax, tracks sales tax collected and remitted, and prepares 1099-NEC totals for contractors. These are estimates to plan around, not a substitute for a tax professional.
