We would like to give the customer 15 days to sign the Document but then after they have signed to reset the Expiration Date to 90 days for us to counter-sign. In our business, the signature for a customer signifies that we will begin building the Fiber from our location to the customer site. The process involves site surveys and cost estimates to determine whether the price on the service provided is accurate. We have already committed to the customer that we will provide Service by having them agree to our terms of Service.
