I would say deliver the goods or I will kill you. Chris's answer sounds the best. Jura is too nice.

Deliver the goods can mean literally that "Our company will deliver the goods you ordered next Wednesday". It is also a 'slang phrase' used a lot. It means that the person achieves what they want to achieve in a good and positive manner "I delivered the goods when I got top marks in my test" or what someone else wants them to achieve "She delivered the goods when she finished painting my bedroom early".

"deliver the goods" means to attain success or reach a desired goal; Examples: 1. Our enterprise succeeded, the company finally delivered the goods. 2. We succeeded in getting tickets to the show because my friends knows people in high places, so he certainly delivered the goods. 3. She struggled to overcome her fears in the pool and won first place. She delivered the goods to her country alright.

it means,when you make business with someone,he pay for the order from you,then the products should be sent to him.
