Comprehensive and Detailed In-Depth Explanation:

E-commerce systems that automate purchasing and billing typically lead to:

Faster procurement cycles due to automated ordering.

Increased accounts payable, as more transactions are processed quickly.

Option A (Higher cash flow) – Unlikely, since faster billing does not always improve cash flow.

Option B (Higher inventory balances) – Incorrect, as e-commerce often enables just-in-time inventory.

Option C (Higher accounts receivable) – E-commerce speeds up collections, reducing receivables.

Since automated purchasing increases outstanding payments, Option D is correct.
