Receiving payments and paying suppliers

[JayLot1988]

Hi all,

I'm after a bit of advice please on how payments work. 

I haven't currently got a store set up but I'm working on it this week. 

I've got my suppliers ready to go etc but the thing I'm struggling to find info on is how payments work. 

The items I'm selling can range from £80-£2000+ depending on how much of the product the customer buys. What I'm reading is that payments can take a few days to reach my account. 

Now, I'm not expecting to hit massive amounts of sales within the first year but if I have to wait 3 days for payment to teach my account, then pay the suppliers before they **bleep**, surely that defeats the purpose of fast delivery and dropshipping? This certain product I can potentially have a 2 week lead time as most suppliers of this are around that but this just adds to the delivery time. 

Also, I read somewhere that sometimes shopify or paypal can hold 50% of thebpayment for upto 45 days. Is this true? Or just hearsay 

Thanks all

Jay
