In sales terminology, an objection is a concern the prospect has about buying your product. Your prospect might choose to describe that concern in detail (“What if it breaks down?”) or just give you a vague delaying statement (“I'll think about it.”).
A condition is something else entirely. When the prospect brings up an issue that truly can't be overcome – for instance, they have a contract with one of your competitors and can't break it – that's a condition. In essence, a condition is something that makes the prospect not qualified to become your customer.
You can and should address your prospect's objections during the sales process. If the prospect raises a condition, however, it's time to throw in the towel on that sale.
