Needs attention
Built for the one- or two-person business that files a Schedule C and finds QuickBooks and TurboTax overpowered.
No accounting degree
No debits and credits, no chart of accounts. Record what came in and what went out — the tax mapping happens underneath.
No lock-in
Import from any bank's CSV, export everything as CSV, PDF, or a receipt-by-receipt evidence ZIP whenever you want.
No April panic
Your Schedule C is built all year, not reconstructed in a weekend. It's ready the day you need it.

Know how you're doing
A dashboard that answers the only question that matters at a glance — am I making money? Revenue, expenses, and profit for the year, with a 12-month cash-flow chart underneath.
Get paid faster
Send an invoice by email, let clients pay online, and watch it move from sent to paid on its own. Outstanding and overdue totals stay in front of you.
Ready for your preparer
92% documented
Survive tax season
Every category maps to a real Schedule C line, every deduction can carry its receipt, and one export gives your preparer the numbers and the evidence together.
The headline feature
A Schedule C you can defend
Plainbooks isn't another dashboard that leaves the hard part to April. Categories are the actual IRS lines, refunds and transfers are handled the way the tax rules expect, and every number drills down to the transactions and receipts behind it.
- Line-mapped categories — Advertising is line 8, Meals is line 24b at 50%, no lookup tables required.
- Transfers, refunds, and out-of-pocket spending handled correctly — so the totals are actually right, not just plausible.
- Export as CSV, a PDF summary, or an evidence ZIP — with an immutable snapshot of exactly what you filed.

Receipts, handled
Snap it. We read it.
Photograph a receipt at the register or drop in a PDF. Plainbooks reads the merchant, date, and total, suggests the transaction it belongs to, and files it as the evidence behind that deduction.
- Phone photos welcome — even iPhone HEIC, converted for you.
- A tidy inbox of anything unmatched, so nothing slips through the cracks.
- Any deduction over $75 without a receipt is flagged before you file.
One simple plan
Try everything free for 14 days — no card required. Keep it for the price of a couple of coffees a month.
