Why are my orders auto-fulfilling without my intervention?

Hello, 

I have a problem with the orders. When an order pops up they fulfilled automaticaly without any action from us. Especially the paid ones. Could you please check it?

You can control this in Settings > Checkout

If you only want to auto fulfill certain items, you can use Order Automator app to choose what gets fulfilled. If you want to fulfill nothing automatically, just select that option in the screenshot above in your Shopify settings.
