Re: E-commerce solution leads...
It'll be an e-commerce site selling a physical product (food), with...
A shopping cart
Ability to upload products
Thus far any decent shopping cart will be able to handle this.
This is probably the most widely used free one:
Ability for other sellers to upload products to their own sections of the site
This is a feature that will restrict the available options. It would be easy to add the ability for subseller uploads to an existing script but I suppose you want their sales tracked etc so that they can get paid as well.
That would be more complicated.
An alternate solution would be to send checkouts of their product to a different gateway but that would make a cart with both top level products and subseller products have to be split. It'd be ugly.
This is easily the most limiting feature if there needs to be tracking for them.
Secure transactions, with payments by paypal (maybe not necessary), credit card (maybe this could go through some 3rd party if that's better or easier), and if it isn't horribly difficult, payment by wire transfer as well (do some banks allow websites to automatically check if a payment has arrived, or would that have to be done manually?)
1) Any cart worth its salt will be able to switch into https. So this is just a matter of having a credit card merchant account and an SSL certificate for secure connections.
If you need a lead for the cheapest place to get SSL certificates PM me for a link.
2) A merchant account is expensive and many people start with their party "gateways".
This is going to be a crucial issue. You need to narrow down your gateway options as few scripts will have modules available for them all.
The gateway must be able to support some kind of auto responder.
There are some payment processor (gateway) links in the portal but if you need more leads send me a PM.
3) Paypal is a common module and they have a good IPN that allows for flexible autoresponding.
4) Wire transfer would probably have to be done manually.
Autoresponder which sends receipts, as well as invoices if payment by wire transfer is possible
This should be pretty common.
