One of my clients needs to have a quite complicated inventory solution. They would like to specify the quantity for each product that would be different for each day. On the front end, the customer then would have to choose a date they would like to have their product picked up/delivered. The inventory would show up for that specific date.
I know that I could build a custom middleware and use API but I was wondering if there is any 3rd party solution/integration with any stock management system that could potentially handle that. Let me know if anyone could point me in the right direction!
