Accounting
Run a set of books end to end - transactions, invoices, bills, journal entries, the bank reconciliation workpaper, month-end close, and reports - for one organization or a portfolio of client books. The ledger, the workpapers, and the AI that works in them do not encode any one country's tax rules.
Same ledger, journals, reconciliation workpapers, close, reports, and MCP assistant wherever your organization is. Where something is United States only, these pages say so and say what happens instead.
Two things are United States only today: the automatic bank feed, and payroll. Everywhere else you upload the statement - CSV or PDF - and the reconciliation workpaper derives from it exactly as it would from a feed, and payroll is recorded by journal. Payroll for other countries is being built.
AI does the heavy lifting
The assistant is now built into Books: a chat panel inside the app, with multiple chats and history like ChatGPT or Claude. It answers from the live ledger - trial balance, balance sheet, P&L, AR/AP aging, account activity - reads the documents you attach or pick from the library, and does the work: journal entries, bank-feed categorization and matching, bank reconciliations, invoice and bill drafts. Every posting stops at an in-chat approval card first, and you pick the model per chat - Gemini, Claude, GPT, or an open model - on every plan. Prefer the assistant your firm already licenses? Connect Google Antigravity, Claude, ChatGPT, or Gemini Spark over MCP and it works the same tools through the same approval gates and the same audit trail. Either way: AI prepares, you approve and post, and a reconciliation is signed by a person or not at all. External AI availability depends on the provider; Gemini Spark eligibility requirements apply.
A typical flow
Bots do the repetitive work; a person reviews and signs off wherever judgement matters.
One set of books, first transaction to close
WorkpaperOS Books was designed by a CPA who is a QuickBooks Online Advanced Certified ProAdvisor (Platinum-tier practice) with an MBA specialized in SAP Finance and years implementing SAP-scale systems. That range is the point: small-firm software teaches you speed, enterprise systems teach you controls - and Books is built to give you both. The bots work like an expert bookkeeper you talk to; the controls work like a system an auditor would sign.
The demo tour
Six illustrated parts follow one fictional CPA-led book - a nonprofit community health center - from AI connection to a closed month.
Part 1
The built-in Books Assistant is already inside the app - or one MCP URL turns Antigravity, Claude, ChatGPT, or Gemini Spark into your expert bookkeeper.

Switching from QuickBooks or Xero?
These aren't hypotheticals: each one is a limitation users report in the QuickBooks Community and Xero Central threads, built out of Books on purpose.
The complaint · QuickBooks Online
Imported journal entries don't get the drill-down-and-edit flexibility that manually keyed ones do - click into one from a report and it fights back.
In WorkpaperOS Books
Manual or uploaded, draft or posted - it's the same entry and the same editor. Click any amount on the balance sheet straight through to the fix, or ask your AI to make it.

Bulk reclassify is reserved for the Accountant edition, skips several transaction types, and can't change the payee. Xero's Find & Recode is advisor-only - and can't be bulk-undone.
In WorkpaperOS Books
Bulk fixes belong to anyone your firm authorizes - previewed before they run, logged in the audit trail, reversible afterward, and runnable by your AI on your instruction.

No native journal-entry import in the US edition - the official answer is to buy a third-party app.
In WorkpaperOS Books
Drafts import natively - a native CSV or Excel workbook your reviewers can open, uploaded directly - then post through your approval queue.

Tags are being retired and class + location tracking caps at 40 on the Plus plan - hard news for grant-funded nonprofits.
In WorkpaperOS Books
Grant, class, program, department, location, and restriction are first-class fields on every journal line - no cap - with grant budget-vs-actual reporting built in.

Undoing a reconciliation needs an accountant user - and without one, you un-reconcile a checkbox at a time.
In WorkpaperOS Books
There is nothing to un-reconcile. Signing a workpaper is a signature, not a lock, so a transaction inside a signed month is still one click from undone - and the app tells you the month will stop tying rather than refusing you. Reopening the workpaper takes one firm admin's click, records a reason, archives the prior report, and re-derives from the ledger.
See it in Part 4What you get
Open the chat panel and ask the live ledger - trial balance, P&L, aging, account activity - or hand it the work: journal entries, bank-feed categorization, reconciliations, invoice and bill drafts. Every posting stops at an in-chat approval card. AI is included with any subscription, every plan can use every model - Gemini, Claude, GPT, and open models - and connecting your own AI over MCP stays included too.
Books never needs cloud storage. Upload documents and support under Documents & Storage and they attach to the entries they prove; import journal-entry drafts directly - native CSV or Excel - and they land in the queue behind the post-lock. The built-in Books Assistant works fully with nothing else connected, and bank and credit-card feeds carry the transactions in on their own.
Double-entry ledger, journal entries, the bank reconciliation workpaper, period close, and the financial reports work the same for an organization in Lagos, Manchester, or Ohio. None of it is built on one country's tax rules.
Two seed charts of accounts: for-profit (61 accounts) and not-for-profit (41 accounts, with donor-restriction net asset classes and functional expense groups). You pick by entity type, not by country, and every seeded account can be renamed, deleted, or added to afterwards.
Each organization carries a country and a base currency, and amounts across the app and the reports are formatted for that currency and locale - including currencies written without decimals.
Automatic feeds cover United States institutions today. Anywhere else, upload the statement - CSV or PDF - and it becomes the bank side of the workpaper: its lines are matched against the ledger exactly as feed rows are, reconciling items are named, adjusting entries arrive as drafts, and the workpaper is signed and printed the same way.
Full payroll processing in Books runs for the United States only right now. Outside it you record payroll from whatever provider you use as a journal, and reconcile the payroll liability accounts in the books. Payroll for other countries is in development - we are not putting a date on it.
Keep your own books or a portfolio of client books, with role-based access, one review queue, and a clear view of what is waiting on someone.
Record adjustments, reconcile the balances, sign the workpapers, and set the closing date. When the file goes to an auditor or a tax preparer, the trial balance and the adjustments are already organized rather than rebuilt from scratch.
