Accounting for Crowdfunded Projects....

Hello, I am looking for some feedback as it relates to the accounting for crowd-funded projects. I am the only accountant at a small start-up in San Francisco that just completed a successful Kickstarter project, and I have limited experience in this area from a financial and tax reporting perspective. I was hoping that someone out there may have some feedback regarding the accounting for Kickstarter projects. In general on Kickstarter, companies list certain pledge items for a specified dollar amount - let's say $50. Is it reasonable to assume that sales tax, shipping/handling, and/or Kickstarter fees are included in the listed price? Or, does it have to be explicitly stated as such ("the listed price includes sales tax, fees, and shipping") for this to be valid? In other words, I am wondering if it is acceptable and legal to deduct the sales tax, shipping/handling, and certain fees from a revenue/sale tax perspective assuming that it is embedded in the $50 pledge amount (so of the $50, $40 would be considered revenue/sales and $10 divided between sales tax payable, the fees owed to Kickstarter, and possibly shipping/handling). Is there any specific guidance in the SEC or FASB rulings that dictate how to account for this? Does anyone have any examples? If anyone has any feedback or resources, it would be extremely helpful and much appreciated! Thank you!
