We are nearing the launch of our website which is a wholesale marketplace and network, which hosts transactions between Buyers and Sellers. We are deciding between two offers for a period of free use and have reached a stale-mate in terms of which one one makes the most sense.
Both are subscription-based models, here are the two versions:
$10(just an example) a month subscription fee. Subscription Billing begins only after you have made your first sale on the website. The day you make a sale, the $10 a month fee is charged and that defines your billing period.
$10(just an example) a month subscription fee with a 30-day free trial. Subscription billing begins one month after the day that you register your account, regardless of whether you sell or not.
There is a 3% transaction fee on all purchases, from the first sale and on, regardless of the free offer.
Any advice would be greatly appreciated in terms of which one would be best to pursue, or if you have suggestions for other models.
