Timeframe client is expected to submit payment on an invoice.

• A. Payment terms
• B. Net 30
• C. Watermark
• D. Portfolio

Answer: (A)

Payment terms set how and when payment is expected. They establish the timeframe for paying an invoice, along with any details like early-payment discounts or late fees. So the timeframe the client is expected to submit payment is defined by these terms. A common example within those terms is Net 30, which means payment is due within 30 days of the invoice date. Watermark is simply a mark on the document to indicate ownership or prevent copying, not related to when payment is due. A portfolio is a collection of work samples and has nothing to do with payment timing.
