Hello -
Considering your arrangement is like Amazon, and Amazon is the
absolute premier online leader of this commission arrangement, their
revenue model would be the best one to mirror.
"Amazon.com is able to generate gross profit margins of at least 75
percent on the [6%-15%] commissions it charges retailers, according to
an estimate by Paul Keung, an analyst at CIBC World Markets. Keung
expects Amazon.com to report net income of $93.3 million, or 22 cents
a share."(1)
Amazon's commission rates are between 6 and 15 percent, depending on
the item being sold:
Computers | 6 percent
Camera & Photo, Cell Phones & Service,
and Electronics items | 8 percent
Items in the Everything Else Store | 10 percent
Musical Instruments | 12 percent
All other product lines | 15 percent <---
There's also an additional closing fee that they realize on each
transaction, tied to the shipping rate, which ranges from a fixed $.65
to $0.65 + $0.10/lb.
Somewhere in the range of 15 percent would be a good starting point
for your business. You could also charge a monthly or yearly fee in
addition to this, such as Amazon's Pro Merchant Subscription
($39.99/mo.), which could offer subscribing merchants additional
perks, such as a waivering of the $.99 fixed closing fee, and
streamlined inventory/listing control.
If you have any other questions, please don't hesitate to ask before
rating this answer.
Thank you,
