Your bot speaks up when someone asks for a size you don't have
If a customer asks for a size you don't sell along with other products, your assistant tells them, lists the sizes you have and keeps the rest of the order.
What you get
- Nothing disappears without a reason: your customer knows why something is missing.
- They pick another size right away: the bot tells them which sizes you have.
- The rest of the order stays: everything else is still in the summary to confirm.
