We only charge commission for leads obtained for that particular season. If they do not go with you the first year, but then they go directly to your site the following year and you close the sale in that 2nd year, then no commission fee would be billed to you. Having said that, if they go thru us that 2nd year and you close the deal that 2nd year, then yes, the commission is applied. If in the event a customer goes through you and through us in the same season, we look at that on a case-by-case basis and see what time the lead arrived. If it came through you before it arrived on our site, then no commission fee applied (however if the reverse happens, then we would take credit).
