How to incorporate consignment orders?

Hello. I would like to know if anyone has any ideas on how to put a consignment order in the system which can be amended as the stock sells over a period of time. I have a few shops selling my kids tshirts but they are on a sale or return basis. I want to put the consignment order into opencart so I have an accurate stock remaining count. I also would like to find a quicker way of ordering large amounts of products. Since I have tshirts for sale with various options it seems a little laborious to order the same shirt in 4-5 different options. I may post this as a separate question but thought there maybe an extension that covers the two issues. I'm using 1.5.2.1
Thanks for any advice, Craig.

Can you explain what you mean by 'consignment order'?
As for ordering large amounts of products with varying amounts is this what you mean?

Hi Jay. Thanks for those 2 links. They look very much like what I need for the larger ordering. In regards to the consignment orders. I have started a kids clothing line and are selling on my website as well as supplying bricks and mortar boutiques. A few of the boutiques are on the consignment agreement which is really just a sale or return basis. The boutiques are given x amount of products and only pay me once they sell some. The problem is that I want to keep my stock take accurate while these products are in the boutiques. For instance if I have 100 shirts on consigments for a few months but have no record of it in opencart then I may have online orders for products that aren't in stock. I am currently making a dummy order for the consignment order which I then have to delete and reorder the amended consigment as the boutique starts to make sales. I also then have to make the actual sold products order so I can invoice them. I'm not entirely sure if these deleted dummy orders will be added back onto my stock levels. Its a very convuluted and tedious process. I hope this has made sense and thankyou for your help.
Regards, Craig.

You would likely need to pay a developer to custom code your requirements. I would recommend you post the job in the commercial support forums if you have a budget for this and see what offers you get

Hi Jay. Thanks for your recommendations.

Cheers, Craig.
