There was a time when you had to go to your database, and manually erase all of your dummy orders and related data manually. That was the past. You can now delete Prestashop orders in one click with my free module.
To grab it, just head over to the shop, and dowload it, here!
It couldn’t be easier to use: install it (under Modules, Administration Tab), set the order ID where you want to start erasing from, and let the module to the job for you! Of course, it will also erase all of the useless related data, leaving your database as clean as a glass.
It’s compatible with Prestashop 1.3 to the most recent version (184.108.40.206 at the time i’m writing). I’ve not tested it with previous versions, but there is no real reason why it should not work. Of course, i’ll update it as soon as Prestashop 1.5 is released, since from what i’ve seen in the release candidate, those guys have no intention to give us a clean way to delete Prestashop orders in the near future.
