So I'm planning on launching an ecommerce site but
need to raise some investment on top of the savings I can put in to it.

Do I need to have a website fully functioning or will paper designs or even descriptions suffice at this stage while putting together a business plan?

I'm very reluctant to spend lots of money on my web ideas before I can raise any capital.

Also, most of the funds I will be trying to raise will have to go on stock which will be my biggest expense as I need to get stock in the first place

Got so manys ideas, I just have NO idea when it comes
to spending money, mainly because I've been a saver than a spender!
