Hey there, @axeconstructionedmonton.
Once an invoice is voided in QBO, it cannot be undone. This is because voiding a transaction permanently removes the amounts while retaining the original invoice number and audit trail for record-keeping purposes.
If you need to restore a voided invoice, you’ll need to recreate it manually. Here’s how:
- Locate the voided invoice by going to the Audit Log under the Gear icon.
- Review the details of the voided invoice, including the Customer, Line items, and Amount.
- Create a new invoice in QuickBooks and re-enter the details as they appeared on the original invoice.
It's also worth noting that QuickBooks retains the invoice number for traceability, so the recreated invoice will have a different number unless you manually adjust it.
If you have any other questions or need further assistance, feel free to revisit this thread.
