If the product an X buyer wants is out of stock, do not recommend the nearest item just because you can sell it. Check whether an available alternative meets their essential requirements and can reach them in time. If not, offer a restock option only when you can substantiate its timing and it works for the buyer. When neither option meets the request, say so rather than make a promise you cannot keep.
Check what you can actually fulfill
Read the buyer’s post and any later replies before choosing a product. Separate requirements from preferences: a mounting method, size, compatibility, budget or deadline may rule out an item that otherwise looks close. If an essential requirement is unclear and changes which item would work, ask about that requirement rather than guessing.
Then check the facts you control: current sellable stock, the available item’s specifications, where the buyer needs delivery and whether you can meet the stated deadline. For a restock, distinguish a confirmed incoming quantity and expected availability from a tentative supplier estimate. Availability on a given day is not the same as arrival at the buyer’s address on that day. If either stock or delivery timing remains uncertain, do not present it as assured.
Choose an alternative, a restock option, or neither
Use the buyer’s non-negotiable requirements as a gate, not a score: an item that fails one of them is not a suitable recommendation even if it meets every other preference. A restock is useful only if its substantiated timing, plus delivery time, fits what the buyer can wait for. Apply the same standard to both options rather than favoring whichever generates a sale sooner.
| What your checks show | Action | What to make clear |
|---|---|---|
| An available alternative meets essential requirements, and fulfillment fits the deadline. | Recommend the alternative. | Name the relevant differences from the requested item; do not call it identical if it is not. |
| No suitable available alternative; confirmed restock and feasible delivery fit the buyer’s timing. | Offer the restock option. | State what is confirmed, what remains an estimate and whether the buyer would need to wait or order later. |
| A requirement is unclear and determines whether an available item would work. | Ask a focused question first. | Do not recommend the item before the buyer confirms the missing requirement. |
| No suitable available alternative meets the essential requirements, and no confirmed restock option can meet the buyer’s timing. | Decline to recommend either option. | Explain the specific mismatch without implying that an uncertain restock solves it. |
When the in-stock substitute is the wrong answer
Consider this fictional request posted on a Monday: “I need a clamp-on desk lamp by Friday. Any recommendations?” The seller confirms that the clamp-on model is sold out, a freestanding lamp is in stock and could arrive by Friday, and the clamp-on model has a confirmed restock the following Tuesday. The buyer has specified both a mounting method and a deadline. The freestanding lamp fails the mounting requirement; Tuesday’s restock misses Friday even before delivery time is considered. The resulting action is to decline both offers for this request, not to promote the freestanding lamp as a close match.
Changing an input changes the decision. In one fictional variation, the buyer says a freestanding base will work; the seller confirms that the in-stock lamp fits the buyer’s desk and can arrive by Friday. The decision is to recommend that lamp, while identifying its different base. In another fictional variation, the clamp remains essential, but the buyer says delivery next Thursday is acceptable. The seller confirms Tuesday’s restock and verifies that delivery by next Thursday is feasible. The decision is to offer the clamp-on lamp as a restock option, stating its availability and delivery timing accurately. If delivery timing cannot be verified, the seller should not promise that date; they could instead offer an update if they can provide one.
When declining, give the buyer the useful reason: “I only have a freestanding lamp available by Friday, so I can’t recommend it for a clamp-on setup. The clamp-on model won’t be available in time either.” That fictional answer respects the buyer’s constraints without steering them toward a product they did not ask for.
Review the suggested reply against your stock check
ReachFast says it uses a submitted website to find and rank relevant public X requests, and prepares a suggested reply that opens in the X thread for the seller to send. That can bring an out-of-stock request to your attention, but the inventory, substitute and timing decision still needs your own checks. Before sending, replace any unsuitable suggestion with the alternative, substantiated wait or honest decline your checks support—or skip the reply.
This is the fulfillment decision, not a template for every public conversation. For help phrasing a recommendation after you have chosen a suitable offer, see the guide to replying to a product recommendation request on X. If you are still deciding whether the post is a buyer request worth answering at all, use the request qualification guide.
