Is there a way to restore deleted transactions?

I have deleted some duplicated transactions because I found the duplicated records in the warehouse. So I did the logical thing and deleted the invoices but this did not result in removing the excess inventory in the warehouse. I tried to correct this error but I found no other way but to adjust the amounts using the correct stock button manually.

How can I undelete/restore the deleted invoices?
Thanks.

Easiest solution would be to upload a backup into your system. But assuming this does not exist: Did you just delete the invoice documents (PDF)? They can be regenerated. But if you deleted the entire invoices, I assume they are gone and you cannot get them back.

As an additional note: Depending on the country, it is not advisable to delete existing invoices from the accounting system, but this may vary in different legalities.

Sadly no backups are available. I am just testing things out.
Thanks for your help.

Hello Gazzaz,

did you delete also the shipment sheet created in the order process?
