Bookkeeping for LLC owners and freelancers
Plainbooks keeps the books. Receipts and statements go in, every transaction is filed by category and tax line, the reports add up as you go, and your accountant gets one folder in January.
For iPhone and iPad. $9.99 a month or $79.99 a year, with a 14-day free trial on the yearly plan.

Profit and loss, cash flow, spending.


Every expense on its tax line.
Up to 10 books: LLCs, side gigs, personal.

One zip for your accountant.

The fastest way in. A minute a week keeps the books current; here is the minute.
Point the camera at the receipt. Plainbooks finds the edges, squares the paper and keeps a clean copy. Receipts you already have as photos or PDFs work too, and so does a CSV from your bank or card.
The shop, the date and the total are read on the phone, from the full-resolution original. A weak read (no total, or two that disagree) is flagged, never guessed.
With its Schedule C line, and how much of it counts. Weak reads get a second look from AI and come back marked “read by AI, please check”. Your own rules always win. You check and save.
Filed under the business, the category and the year, with the receipt attached. Offline? It waits in the outbox and uploads itself when you’re back, even if the app is closed.
Net profit against the same days last year, a profit and loss you can share as a PDF, cash flow with runway, and the tax view: totals by Schedule C line, how much to set aside, and a reminder a week before each estimated-tax date. Every number is plain arithmetic, checked in tests; the AI never computes one.

Close the year with a checklist and a lock, then export a business for a year, or everything: the profit and loss, the transactions and categories as CSV, every document, and the receipt photos if you want them. A zip in Files, ready to share. No login for your accountant, nothing to install.

One LLC or several, up to 10 books, plus a personal book if you want one. Each has its own categories, accounts and years, and its own place in the switcher. Paid for something with your own card? Plainbooks records the expense and your owner contribution together, so the books still balance.
Income, expenses, refunds, owner draws and contributions, transfers, tax payments. Each one filed by kind, category and account, split across categories when it needs to be, moved between books as a linked pair. Plainbooks knows which of them count in profit and which never do, so the reports are right without a second set of books.
Counts in profit and loss
Never does
Bring in a CSV from your bank or card; Plainbooks suggests which column is which and shows a preview before anything is sent. Payout reports from Stripe, Shopify and the App Store are read as they are, fees and refunds included.
Formation papers, the EIN letter, the operating agreement, 1099s and bank statements, kept with the business they belong to and included in every export.
Correct a shop’s category twice and Plainbooks offers a rule. From then on it files that shop your way, ahead of any suggestion.
A checklist for the year, then a lock. A locked year is read-only; unlocking asks for Face ID and a reason, and both are kept in the history.
A multi-member LLC gets each member’s share, guaranteed payments and a partners’ capital report, so the split is never a spreadsheet.
Capture receipts anywhere. They wait in the outbox and upload when you’re back, even if the app has been closed for days.
This month’s or this year’s profit on the Home Screen, for one business or all of them, and a Scan receipt button for the Lock Screen, Control Center and the Action button.
English, Spanish, Portuguese, Chinese (Simplified and Traditional), Vietnamese and Korean, with the categories and the Help & FAQ in each.
Receipts are read on the iPhone, from the original. The AI sees the text, and the photo only when the phone’s read was weak. It suggests; it never changes data and never computes a number you see.
Plainbooks only knows what you give it. There are no ads, no analytics in the app, and nothing sold or shared. Sign in with Apple or Google; no password to keep.
Files are private and downloaded only through signed, expiring links. Delete the account in Settings and every row and file is gone within 24 hours.
