| On hold |
Generally, this status is used for an invoice that is a draft.
This is the
default status for new documents if the Hold documents on entry check
box is selected in the Supplier ledger preferences (AP101000) window.
An invoice with the
On hold status can be edited. |
| Balanced |
After editing is completed, you take the invoice off hold, thus changing its status to Balanced. If the Validate document totals on entry option is selected in the Supplier ledger preferences (AP101000) window, you can take the invoice off hold only if you type the document control total. |
| Pre-released |
The status indicates that the invoice has been pre-released and requires expense reclassification. (This status is used only if the Support for expense reclassification functionality is activated.) |
| Open |
This status means that the document has been released (and approved, if required). |
| Closed |
This status reflects that the document has been paid. |
| Scheduled |
This status indicates that the document is assigned to a schedule, and a new document that is similar to the original one is generated periodically. |
## Release of invoices
To release invoices in bulk, use the [Release supplier documents (AP501000)](/visma-net-erp/help/supplier-ledger/supplier-ledger-windows/release-supplier-documents-ap501000/) window. For individual invoices, use the [Purchase invoices (AP301000)](/visma-net-erp/help/supplier-ledger/supplier-ledger-windows/purchase-invoices-ap301000/) window.
A batch created upon release of the invoice is numbered in accordance with the number series assigned to the batches originating in supplier ledger.
## Invoice approval for payment
If approval of invoices is not required in your system, all invoices, upon release, appear in the [Process payments (AP50301S)](/visma-net-erp/help/supplier-ledger/supplier-ledger-windows/process-payments-ap50301s/) window and
you can pay them.
If approval of invoices is required before invoices may be paid, then upon release, the invoices appear
in the [Approve invoices (Approval) (AP50200S)](/visma-net-erp/help/supplier-ledger/supplier-ledger-windows/approve-invoices-approval-ap50200s/) window, from which you can
approve them.
Approved invoices appear in the [Process payments (AP50301S)](/visma-net-erp/help/supplier-ledger/supplier-ledger-windows/process-payments-ap50301s/) window and you can pay them.
## Correcting errors on invoices
Once released, a supplier ledger document cannot be edited or deleted; to
correct it, you can issue an adjustment.
Before you save the adjustment, type another **Supplier reference** value if the **Raise an error on duplicate supplier reference number** option is selected in the [Supplier ledger preferences (AP101000)](/visma-net-erp/help/supplier-ledger/supplier-ledger-windows/supplier-ledger-preferences-ap101000/) window.
## Invoice payment
You can pay invoices individually by using the [Supplier payments (AP302000)](/visma-net-erp/help/supplier-ledger/supplier-ledger-windows/supplier-payments-ap302000/) window or in bulk in the [Process payments (AP50301S)](/visma-net-erp/help/supplier-ledger/supplier-ledger-windows/process-payments-ap50301s/) window.
