Forget about the technology for a minute and think of the practical challenges you face.
1. How does your system separate out YOUR products from the DROPSHIP products. Yours need payment and shipping, but the dropship ones don't.
2. How do customers then pay for the dropship products if their order is a combination of both yours and dropship. They pay YOU and then they pay SOMEONE ELSE. That would pi$$ most people off.
3... there are many more... just think for a few minutes...
Then, programming zc to behave in a way that can separate out products and split the order for calculation purposes is a massive challenge...
Good Luck...
PS: this is a REALLY challenging drop ship requirement
