What is a payment block?
A payment block is a control that prevents a supplier invoice, account or payment item from being selected for payment. It is used when payment should be held until a defined issue has been reviewed and resolved.
A payment block does not necessarily stop all activity on the vendor account. Its purpose is to control payment selection for the affected item or account.
Why are payment blocks used?
Payment blocks can be applied for reasons including:
- An invoice requires approval
- A price or quantity difference needs investigation
- Required supporting documentation is missing
- A duplicate invoice is suspected
- A supplier statement has not been received or reconciled
- A dispute with the supplier remains unresolved
Some blocks are set automatically by SAP processes, while others are applied manually or through configured controls.
How does a payment block work in SAP?
When the automatic payment programme selects due items, an active payment block can exclude the affected item from payment. The block must be removed or released by an authorised user before the item can be paid, subject to the organisation’s configuration.
Example: A supplier invoice appears in SAP, but the supplier statement shows a credit note that is not yet recorded. The payment may be held while the accounts payable team investigates the discrepancy and confirms the correct balance.
How are payment blocks managed?
A controlled process should make it clear:
- Why the block was applied.
- Which document, item or account is affected.
- Who owns the investigation.
- What evidence is needed for release.
- Who is authorised to remove the block.
Payment blocks that remain unresolved can delay legitimate supplier payments and affect supplier relationships. They should therefore be reviewed regularly rather than left as an open-ended control.
How can supplier reconciliation inform payment blocks?
Supplier statement reconciliation can identify missing invoices, missing credit notes, unapplied payments and other differences before the payment run.
The BEST Vendor Recons module compares supplier statements with SAP vendor-account data and supports investigation and approval within SAP. BEST can optionally apply a payment block where the configured statement-matching requirement has not been met. The exact control should be agreed by the finance team and reflected in the organisation’s payment policy.
Frequently asked questions
Is a payment block the same as an invoice block?
The terms can overlap, but they are not always identical. An invoice may be blocked during invoice verification, while a payment block specifically prevents an item from being selected for payment.
Can a blocked supplier invoice still be posted?
Depending on the type of block and configuration, an invoice can be posted but remain unavailable for payment until the block is released.
Who should remove a payment block?
Only an authorised user following the organisation’s approval and control process should release a block.
