Voiding a sales invoice

Voiding fully reverses an approved sale. It is not the same as deleting, returning, or deactivating an invoice.

How the actions differ

Action	Result
Delete	Removes a record that is eligible for deletion
Sales return	Returns all or some lines through a separate return invoice
Deactivate	Removes an approved invoice from the active list
Void	Creates a new void invoice and reverses the original sale’s effects

Conditions for voiding

The original invoice must be an approved sales invoice.
It must have no payments.
It must have no approved return.
Each invoice can be voided only once.
The void date cannot precede the original sale date.
The date must fall in the active fiscal year.
The void invoice number must be a positive integer, unique within the company.
An invoice transferred to another fiscal year cannot be voided.

Steps

Open the sales invoice.
Select Void from its actions.
Enter the void invoice date and number.
Read the warning and confirm the action.
Review the new invoice under Invoices → Sales → Voided Sell.

Accounting and inventory effects

The app copies the original sale’s lines and amounts into the void invoice, then creates a reverse sales document, records a reverse inventory movement for goods, reverses cost-of-goods-sold effects, and links and approves the void invoice against the original.

The original invoice is not deleted. Keeping both records is essential for an audit trail.

Checks after voiding

The original invoice still exists.
The void invoice is linked to the original sale.
Lines and amounts match across the two invoices.
The reverse document balances.
Goods stock was restored correctly.
The customer balance was corrected.
No incompatible payment or return remains.
