Hi MIK,
You are looking at a development. I would strongly advise that this is done in dexterity.
Do you know the retail price of an item?
Does your company enforce the retail price - or can the distributor change the price?
If they can change the retail price - how do they communicate to you what they have sold and at what price?
The development for this may not be that difficult - all depends on exactly what you need. I would advise completing a functional specification.
Best regards,
Ian.
