Yes. We will be using PledgeManager.
PledgeManager is a crowdfunding fulfillment tool, like BackerKit and others, and a godsend to project creators like myself. It is reliable, accurate, and flexible, making the logistical side of Kickstarter a much smoother, and easier, process for project creators and backers alike.
It is used to collect the project's shipping data from backers and also provides an easy way to manage add-ons. An email will be sent to backers after the project, inviting them to join, much like a Kickstarter survey. Also, its services allow backers to easily manage and update their addresses at anytime (prior to shipping, of course).
PledgeManager is highly reputable and is created by the great team behind KickTraq.
