# Accounting Workflows

Autopilot, the Ledger, reconciliations, bills, invoices and the people you do business with.

## Ask Zera

- [What Ask Zera can do](https://www.zerabooks.com/help/ask-zera/what-ask-zera-can-do): Ask Zera is the bookkeeper built into ZeraBooks. Ask in plain words and it answers from your books or does the work, from a quick fix to catching up months of books, using ZeraBooks' own tools and checks. Here is how to open it and what to ask.
- [What Zera knows about your business](https://www.zerabooks.com/help/ask-zera/what-zera-knows): Ask Zera remembers what you tell it about your business and keeps its own profile of the company, built from your books. It uses both in every chat, and you can read it any time under What Zera knows.
- [Do your books with Ask Zera](https://www.zerabooks.com/help/ask-zera/do-your-books-with-ask-zera): Ask Zera catches up months of bookkeeping from one plain message. Attach your statements and say "do my books": Zera imports and checks each statement, categorizes, adds bills and invoices, reconciles every month, signs off what ties and closes the books, asking you only what only you can answer.
- [Give Zera statements, bills and receipts](https://www.zerabooks.com/help/ask-zera/give-zera-statements-bills-and-receipts): Drop up to 20 statements, bills, receipts and invoices onto any page and Ask Zera reads each one, matches it to the right account, vendor or customer, and adds it to your books. You can also type a bill or invoice in plain words.
- [Approve, skip and undo with Ask Zera](https://www.zerabooks.com/help/ask-zera/approve-skip-and-undo-with-ask-zera): By default, every change Ask Zera makes to your books arrives as a card that waits for your Approve or Skip, and every applied change can be undone from its card. Here is how to read a card, approve or skip it, and undo a change afterwards.
- [Let Zera apply changes by itself (Auto-approve)](https://www.zerabooks.com/help/ask-zera/auto-approve): Auto-approve lets Ask Zera apply changes to your books as it makes them and keep going on its own, instead of waiting for you to approve each card. Every change can still be undone, and anything that can't be undone, such as emailing a customer, still asks first.
- [Troubleshoot your books with Ask Zera](https://www.zerabooks.com/help/ask-zera/troubleshoot-your-books-with-ask-zera): Ask Zera finds out why a month doesn't tie, why a number looks wrong, or whether anything is duplicated or missing. It re-reads the statement and your books, explains the cause in plain words, fixes it, and checks again until the month ties.
- [Ask Zera safety, privacy and limits](https://www.zerabooks.com/help/ask-zera/ask-zera-safety-privacy-and-limits): Ask Zera changes your books only through ZeraBooks' own tools and checks. By default every change waits for your approval, it works only in the company you have open, text in documents can't instruct it, and every figure comes from your reports, not AI arithmetic.

## Autopilot & AI

- [How AI works in ZeraBooks](https://www.zerabooks.com/help/autopilot/how-ai-works-in-zerabooks): ZeraBooks uses AI to read your documents and judge what each transaction means. It acts when it is sure, asks you when it isn't, and calculates every number itself.
- [What Autopilot does for you](https://www.zerabooks.com/help/autopilot/what-autopilot-does): Autopilot works through your books in one pass: vendors, categories, bills and invoices, reminders, a second look, month-end and a monthly summary. It runs when you click Run now or while ZeraBooks is open.
- [Answer Autopilot's questions](https://www.zerabooks.com/help/autopilot/answer-autopilot-questions): When ZeraBooks can't tell, it asks in Needs you with one-tap answers, its best guess first. Here is how to answer, skip, and what each kind of question means.
- [Review and undo AI actions](https://www.zerabooks.com/help/autopilot/review-and-undo-ai-actions): Everything ZeraBooks does on its own is listed in Done by AI with how sure it was. Here is how to check the actions flagged for a glance, undo one, and what can't be undone.
- [Choose how much ZeraBooks does on its own](https://www.zerabooks.com/help/autopilot/choose-how-much-zerabooks-does): Pick Cautious, Balanced or Autopilot to set how sure ZeraBooks must be before it acts, and use four switches to decide what it may do by itself.
- [Month-end entries](https://www.zerabooks.com/help/autopilot/month-end-entries): Autopilot proposes depreciation, the interest part of loan payments and prepaid-expense spreads, and asks about recurring bills that didn't show up. Here is how each one works.
- [The auditor's notes and the monthly digest](https://www.zerabooks.com/help/autopilot/auditor-notes-and-monthly-digest): On every pass ZeraBooks takes a second look at your categories, flags possible duplicates and explains months that don't tie, then sums up the latest complete month.

## Ledger & Categories

- [Navigate the Ledger](https://www.zerabooks.com/help/ledger-and-categories/navigate-the-ledger): The Ledger shows every category's register for the period you pick, built from your categorized bank and card activity plus the entries you add yourself.
- [Record a journal entry](https://www.zerabooks.com/help/ledger-and-categories/record-a-journal-entry): Use a journal entry for adjustments that don't move money through a bank, such as accruals, prepaid expenses, depreciation or corrections between categories.
- [Record money in, money out and transfers](https://www.zerabooks.com/help/ledger-and-categories/record-money-in-money-out-and-transfers): Use Pay In, Pay Out and Transfer to record money that moved through a bank or card account before its statement arrives, such as a cash deposit or a check you wrote.
- [Import journal entries](https://www.zerabooks.com/help/ledger-and-categories/import-journal-entries): Bring in up to 100 balanced journal entries at once from a CSV or Excel file. ZeraBooks checks the whole file first, and if any entry fails, none are posted.
- [Edit or remove a manual transaction](https://www.zerabooks.com/help/ledger-and-categories/edit-or-remove-a-manual-transaction): Change or remove a journal entry, Pay In, Pay Out or transfer you recorded yourself. Removing one can be undone; a statement-matched entry must be unmatched first.
- [Transaction details and the activity log](https://www.zerabooks.com/help/ledger-and-categories/transaction-details-and-activity): Open any transaction to see where it came from, which category it's in and why, how often you pay the same party, and change its category.
- [Split a payment across bills or invoices](https://www.zerabooks.com/help/ledger-and-categories/split-a-payment): When one deposit pays several invoices, or one payment covers several bills, split the bank transaction across them so each balance is settled.
- [Understand the Category Manager](https://www.zerabooks.com/help/ledger-and-categories/understand-the-category-manager): The Category Manager is your chart of accounts: every category your transactions post to, grouped into eight types and numbered so reports stay in order.
- [Set up your chart of accounts](https://www.zerabooks.com/help/ledger-and-categories/set-up-your-chart-of-accounts): Start your categories one of three ways: let AI draft a chart for your business, import the one you already have, or build it yourself one category at a time.
- [Generate categories with AI](https://www.zerabooks.com/help/ledger-and-categories/generate-categories-with-ai): Describe what your business does and ZeraBooks drafts a complete, numbered chart of accounts for it. You review and edit every category before anything is saved.
- [Import a chart of accounts](https://www.zerabooks.com/help/ledger-and-categories/import-a-chart-of-accounts): Bring your categories over from QuickBooks, Xero, Sage, any spreadsheet or a PDF. ZeraBooks reads the file, you review every row, and existing categories are never overwritten.
- [Add, edit, deactivate and reactivate categories](https://www.zerabooks.com/help/ledger-and-categories/add-edit-and-deactivate-categories): Create a new category, change its name, parent or number, and turn off categories you no longer use. Categories are never deleted, so your history stays intact.

## Reconciliations & Month-end

- [How reconciliation works](https://www.zerabooks.com/help/reconciliations/how-reconciliation-works): ZeraBooks checks every account, month by month, against the bank's own statement. Here is what the three checks are and what every dot on the timeline means.
- [Fix a month that doesn't tie](https://www.zerabooks.com/help/reconciliations/fix-a-month-that-doesnt-tie): When a statement and your ledger disagree, the month shows an orange ! on the timeline. Here is how to find the difference and fix it, usually in a minute.
- [Verify a statement with AI](https://www.zerabooks.com/help/reconciliations/verify-a-statement-with-ai): When a statement doesn't tie, ZeraBooks can re-read the original document line by line and propose only the fixes that make it tie. You apply them with one click.
- [Finalize a month](https://www.zerabooks.com/help/reconciliations/finalize-a-month): Finalizing signs off a month that ties, recording what you verified and when. Here is how to finalize one month, or every tied month at once.
- [Reopened months and removing a sign-off](https://www.zerabooks.com/help/reconciliations/reopened-months): A finalized month reopens on its own when its checked numbers change. Here is how to see what changed, remove a sign-off, and finalize again.
- [Close and reopen the books](https://www.zerabooks.com/help/reconciliations/close-and-reopen-the-books): Closing the books locks every date on or before a day, so nothing reconciled can change by accident. Here is how to close through your reconciled month, and how to reopen.

## Bills (AP)

- [The Bills board](https://www.zerabooks.com/help/bills/bills-board): Every bill you owe sits in one board, sorted into lanes by where it is: waiting for your review, posted and still owing, or paid.

- [Mark a bill as paid](https://www.zerabooks.com/help/bills/mark-a-bill-as-paid): Record a bill you paid outside your uploaded statements, such as a check or cash, so ZeraBooks knows it's settled. It records the payment; it doesn't send one.
- [Delete, void or reopen a bill](https://www.zerabooks.com/help/bills/delete-void-or-reopen-a-bill): Delete a draft that never posted, void a posted bill while keeping it for the record, reopen a posted bill to fix it, or restore a voided one.

## Invoices (AR)

- [The Invoices board and statuses](https://www.zerabooks.com/help/invoices/invoices-board): Every customer invoice sits in one lane on the Invoices board, from Draft to Paid. Here is what each lane and status means and how an invoice moves between them.

- [Automatic payment reminders](https://www.zerabooks.com/help/invoices/payment-reminders): Autopilot emails customers about invoices a week or more overdue, at most once a week. Here is exactly when a reminder goes out, when it asks you first, and how to turn it off.
- [Record payments, partial payments and credits](https://www.zerabooks.com/help/invoices/record-payments-and-credits): Settle an invoice by matching the customer's deposit from your bank statement, applying a credit, or marking it paid when the money came in some other way.
- [Credit memos](https://www.zerabooks.com/help/invoices/credit-memos): A credit memo is an invoice with a negative total. Create one to credit a customer, then apply it to one of their unpaid invoices.
- [Edit, duplicate, void or delete an invoice](https://www.zerabooks.com/help/invoices/edit-duplicate-void-or-delete-an-invoice): Change an approved invoice, copy it into a new draft, cancel it with a void, or delete a draft. Here is when each one is allowed and what it does to your books.

- [Invoice accounting settings](https://www.zerabooks.com/help/invoices/invoice-accounting-settings): Tell ZeraBooks which accounts invoices post to — Accounts Receivable, sales tax, holdback and settlement differences — and when documents post on their own.

## Vendors, Customers & Products

- [The Vendors and Customers pages](https://www.zerabooks.com/help/vendors-customers-and-products/vendors-and-customers-pages): See everyone you pay and everyone who pays you, with their activity for the period, what's still owed, and every transaction behind the totals.
- [Add, edit, deactivate or merge a vendor or customer](https://www.zerabooks.com/help/vendors-customers-and-products/manage-vendors-and-customers): Create a vendor or customer before their first bill or invoice, keep their details current, stop offering one you no longer use, and merge duplicates.
- [Link bank descriptions to saved vendors](https://www.zerabooks.com/help/vendors-customers-and-products/link-bank-descriptions-to-vendors): Put bank transactions under the vendor they belong to. ZeraBooks suggests links it's sure of, and every similar transaction in every month follows.
