# Cash Basis AI

> AI-powered cash-basis bookkeeping and real-time tax estimates for the self-employed.

Cash Basis AI is a bookkeeping and tax app built for freelancers, independent
contractors, 1099 earners, single-member LLCs, S-corps, and other solo business
owners. It connects to your bank and cards through Plaid, automatically
categorizes every transaction with AI, keeps a real-time cash-basis income
statement and balance sheet, and continuously projects your quarterly estimated
taxes. A built-in assistant named Cash answers questions about your finances in
plain English over text.

## Who it is for
Self-employed people who file a Schedule C and keep their books on the cash
basis: freelancers, independent contractors, 1099 earners, single-member LLCs,
and S-corp owners. It is for people who need real bookkeeping without hiring a
bookkeeper or learning accountant-oriented software. You can invite your CPA to
your books on every plan.

## The problem it solves
Most self-employed people do not know what their business made, what is
deductible, or how much to set aside for taxes until it is too late. Legacy
accounting tools are expensive, rule-brittle, and update taxes only once a
quarter. Cash Basis AI does the categorization automatically, keeps the tax
estimate current in real time, and lets you just ask when you have a question.

## What makes it different
- Built for the self-employed first, not adapted from accountant software.
- Costs a fraction of what legacy accounting tools charge.
- AI categorization instead of fragile rules — it categorizes on its own, then
  asks you about the gray areas rather than guessing, and remembers your answer.
- Real-time quarterly tax estimates instead of once-a-quarter math.
- Ask questions in plain English instead of learning a ledger UI.
- Cash-basis on purpose — the way most solo operators already think about money,
  and how the IRS lets most small businesses file.

## What it does
- Connects to your bank and cards through Plaid and imports transactions.
- Categorizes transactions with AI, surfacing the uncertain ones for a one-tap
  review rather than silently guessing.
- Keeps a real-time cash-basis income statement, balance sheet, and cash flow.
- Projects federal, self-employment, and state quarterly estimated taxes as the
  year unfolds, with reminders before each due date.
- Answers questions about your books in plain English by text.
- Invoicing, mileage, receipt capture, audio recaps, and accountant access.

## Pricing
Three plans, billed monthly or annually. Annual saves 20% versus paying monthly.

- Auto-Pilot: $9/month or $86/year. Complete bookkeeping for solo businesses.
- Co-Pilot: $19/month or $182/year. Everything in Auto-Pilot, plus AI intelligence.
- Command: $35/month or $336/year. Everything in Co-Pilot, plus multi-business tools.

## Trial and guarantee terms
These differ by billing cycle and are not interchangeable:

- Monthly plans include a 14-day free trial. A card is collected up front and the
  first charge happens when the trial ends unless you cancel.
- Annual plans have NO free trial. The full year is charged at checkout, and is
  covered by a 30-day money-back guarantee instead.
