# Bills (AP)

Read, approve, match and pay what you owe.

- [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.
- [Upload a bill](https://www.zerabooks.com/help/bills/upload-a-bill): Upload a PDF or photo of a vendor bill and ZeraBooks reads the vendor, number, dates, lines and categories for you.
- [Create a bill by hand](https://www.zerabooks.com/help/bills/create-a-bill): Enter a bill without a document: pick the vendor, add each line with its price and category, and add a holdback or reverse charge when you need one.
- [Why a bill is waiting](https://www.zerabooks.com/help/bills/why-a-bill-is-waiting): A bill posts on its own only when seven checks pass. Here is each check, what it means when it's unmet, and how to clear it.
- [Approve or reject a bill](https://www.zerabooks.com/help/bills/approve-or-reject-a-bill): Approving a bill posts it to Accounts Payable in one click. Here is how to approve, what happens with a new vendor, and how to return a bill for correction.
- [Match a bill to its bank payment](https://www.zerabooks.com/help/bills/match-a-bill-to-its-payment): Once you've paid a bill and the payment is on an uploaded statement, apply it to the bill. Partial payments, bank fees, vendor credits and other currencies are covered.
- [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.
