Availability check during Shipping

Hi,

I want input regarding availability check during shipping.

It's a make to order scenario & I want to know whether availability check is really required during shipping for checking the sales order stock or it can be managed without availability check.

The reason, why I want to avoid availability check is because the quantity of production order is very small say 10 ton of concrete p day. I require a proper logics to convince my client.

Please share your valuable inputs.

Regards

Suman
