Transaction brokers:

Question

BlackTom AI · Accepted Answer

Transaction brokers are intermediaries that process and facilitate online sales transactions, so they primarily save users time and money by handling the mechanics of buying and selling.

1. Relevant knowledge points and concepts
- Transaction broker: a business or service that enables and executes transactions (payment processing, order routing, escrow, settlement) between buyer and seller, reducing friction and transaction costs.
- Other e-commerce roles: marketplaces/platforms (match buyers and sellers or host price discovery), retailers (sell physical products directly), advertising/affiliate sites (monetize by directing traffic), and online communities (enable communication and networking).

2. Step-by-step reasoning
- Identify the core function described by each option.
- Match each function against the textbook definition of a transaction broker.
- Select the option that best matches the role of facilitating and executing transactions.

3. Intermediate reasoning steps (explicit)
- Option A: “save users money and time by processing online sales transactions.” Processing transactions (payments, order fulfillment, escrow) is precisely what transaction brokers do; by automating and aggregating processes they reduce costs and speed transactions.
- Option B: “provide a digital environment where buyers and sellers can establish prices for products.” That describes a marketplace or auction platform (price discovery), not specifically a transaction broker.
- Option C: “sell physical products directly to consumers or individual businesses.” That defines a retailer or direct seller, not a broker that merely processes the transaction.
- Option D: “generate revenue from advertising or from directing buyers to sellers.” That’s an advertising or affiliate business model, not the transactional facilitation function.
- Option E: “provide online meeting places where people with similar interests can communicate.” That is an online community or forum, unrelated to transactional processing.

4. Why the correct answer is correct
Processing online sales transactions (payment handling, order routing, escrow, settlement) directly reduces the administrative burden, speeds up purchases, and lowers per-transaction costs—exactly the benefits described in option A. These are the hallmark services of transaction brokers.

5. Why the other options are incorrect (brief)
- B: describes marketplaces/auction platforms (price discovery), not transaction brokers.
- C: describes retailers who own inventory and sell directly.
- D: describes ad/affiliate models focused on referrals and ad revenue.
- E: describes communities/forums for communication, not transactional processing.

6. Conclusion
Therefore, the correct choice is “save users money and time by processing online sales transactions.” This matches the provided answer.
