The answer just has to be "yes", subject to the number of party-based network marketing type operations, especially those for "soft-goods" such as semi-precious jewelry, soaps/toiletries, candles/ornaments, lingerie/(err)novelties, etc.

Hostessing these sort of deals successfully takes a lot of prep and work up-front, during and after to make sure it runs smoothly, customers are totaled up correctly, orders placed, items delivered etc.

There's likely a wider scope for checklist and CRM-type apps...
