Hi,
There is not yet a tutorial for that feature.
But the goal in HikaShop is "just" to manage the stock.
When you buy the main product, the bundle product stock is also decremented (according to the quantity relation).
With HikaMarket 1.8.0, it will also provide the feature to sell a product which will include products from different vendors and then split the price to the different vendors according to the percentages.

By the way, do not send me private message, use the "contact us" form instead.
