Simply deleting an incorrect invoice sounds like the quickest fix, but from an accounting point of view it is problematic: deletions contradict the principle of traceability and can lead to questions during a tax audit. That is why 1Tool relies on a dedicated cancellation function for invoices that documents corrections properly instead of simply removing data.
A dedicated cancel dialog instead of a simple deletion
To cancel an invoice, 1Tool provides a dedicated cancel dialog. Instead of removing the invoice from the system, this dialog guides you through the cancellation process and ensures that the correction is recorded properly. In addition, a configurable setting controls exactly how the system behaves when invoices are cancelled, so the process can be adapted to your specific requirements.
The original invoice is preserved
A cancellation creates a correcting entry in the form of a credit note that remains linked to the original invoice. The original invoice therefore does not disappear from the system; together with the associated correction, it remains traceable at all times. Anyone looking at the history of an invoice later sees immediately that it was cancelled and why, and finds the corresponding correcting entry right next to it.
Why this matters from an accounting perspective
In GoBD-compliant bookkeeping (the German principles for proper bookkeeping), the traceability of changes is a central principle: business transactions, once recorded, should not be altered or removed retroactively without a trace. A cancellation entry that remains linked to the original invoice meets this principle, whereas a simple deletion would destroy exactly that trail. This also matters to customers: if they have questions about a cancelled invoice, the linked correction shows exactly what was originally charged and how it was subsequently corrected.
