How to correctly handle sales tax collection and accounting when billing a client upfront for inventory that is shipped incrementally to different states over time.

Existing ERP/OMS and tax software assume each sale is a standalone transaction with a known destination, but cannot handle prepaid inventory that is later shipped to unpredictable destinations, leading to accounting and tax compliance uncertainty.
