# Reversing Transactions
**{{variable.GTX Bold}}** enables reversing transactions to correct errors or undo completed processing.
This guide outlines how to perform each type of reversal, including:
* [Customer invoices](/gtx/docs/reversing#reversing-customer-invoices)
* [Payment receipts](/gtx/docs/reversing#reversing-customer-receipts)
* [Supplier payments](/gtx/docs/reversing#reversing-supplier-payments)
* [Delivery dockets](/gtx/docs/reversing#reversing-delivery-dockets)
* [Journal entries](/gtx/docs/reversing#reversing-journal-entries)
* [Bank reconciliations](/gtx/docs/reversing#reversing-bank-reconciliations)
Each process will open the relevant module, locate the original transaction and **create a reversal entry** to offset the original values.
