  • Collect on-line donations
  • Sell sponsorships
  • Collect member fees
  • Sell items for fundraisers
  • Sell items to a member and connect the sale to a financial obligation
  • Collect application fees from a member prospect and connect the sale to an intake path

The Simple Store is designed to be a single page experience, where a user can select an item, or specify a donation, and purchase with a credit card.
