# Ask Zera

Tell Zera what you need in plain words: it does the work in your books, from a quick fix to catching up months, and you choose what it applies by itself.

- [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.
