# Reverse an AP invoice (PAS)

> [!WARNING]
> This help article is related to the Production Accounting Suite (PAS)
> 
> In Wrapbook, production accountants and administrators can manage AP invoices using either the [Production Accounting Suite](/v1/docs/about-production-accounting) or [Cost tracking](/v1/docs/about-cost-tracking). To understand the differences, [click here](/v1/docs/about-production-accounting#production-accounting-faq).

> [!NOTE]
> Accessing AP invoices in PAS is permission based
> 
> To access AP invoices, your account must have one of the following [roles](/v1/docs/permissions-and-access-control) enabled:
> 
> - Role: *Company Admin, Accountant*
> - Custom role with: *Accounting & Cost Tracking / AP invoices - Full access, Create and manage*

You can only reverse *Posted* accounts payable (AP) invoices that haven’t been previously reversed - *Unposted* invoices can [edited or deleted](/v1/docs/edit-delete-or-duplicate-an-ap-invoice-pas).

When reversing an AP invoice you have two options:

- *Reverse* - Creates a posted reversing transaction that cancels out the original AP invoice. The reversed invoice gets the same invoice number with *_R* appended
- *Reverse and reissue* - Creates a posted reversal transaction and creates an unposted duplicate of the original transaction that you can modify

For both options:

- If the AP invoice has associated purchase orders (POs), you'll be asked whether you want to reopen those PO lines or leave them closed
- The timing of the reversal depends on the original transaction period - if it was in a closed period, the reversal goes to the current period; if in the current period, it uses the original dates; if in a future period, it stays in that future period

To reverse an AP invoice:

1. In the left-side navigation, click the dropdown menu
2. In the dropdown menu, select the name of the project that you want to reverse an AP invoice for
3. In the left-side navigation, expand the **ACCOUNTING** menu, click **Accounts payable**
4. On the *Accounts payable* dashboard, click the three dots next to any *Trans. #* that has a status of *Posted,* and select either *Reverse* or *Reverse and reissue*
5. In the *PO lines* popup, click to select either *Reopen PO lines*, or *Close PO lines*

Reopen PO lines - This will duplicate the purchase order (PO) lines and set their status to open

Close PO lines - The PO lines won’t be attached and their status will be set to closed
