Yes, that has been a concern of mine, VAT really eats into the margins. However the reason why I think it might work is the ability for this particular idea to scale in terms of the eventual number of products capable of being listed on the site.
It's got a couple of ways of generating revenue. Some with low margins, some with higher margins, so if I can get people on the site for the low margin items, hopefully I can make some money with the higher margin items.
I've got pretty good access to a portion of my target market, so I'm not too concerned about marketing yet. If I can get the prices right and make the website flow as well as I envisage and work well with the value add features I'm thinking, then I'm hoping word will get out.
Most of the products I will not be stocking personally or doing any of the packaging and shipping. It will all be fulfilled professionally elsewhere to begin with, so I just have to work on getting the orders in, placing the orders with suppliers, admin and CS.
Many of the products I don't have to pay for until I order them, as they're being drop shipped, so my money isn't tied up in them. So it costs me nothing to have them 'In Stock', it just costs my time to generate them and administer the shop.
I agree it will be a very tall order to shift enough product to hit my goal in 2 months. Luckily as this shouldn't be too capital intensive I've still got a little cash to play with in case I think of any other ideas or encounter any other opportunities in the mean time.
Time is my main adversary right now seeing as I can only work on this part time and I think it will take me another week or two to get the website to a point where I'm ready to start promoting it.
