Why Transparent Pricing Matters
Most clients aren’t looking for another conversation prior to purchase. They want an easy way to get the ball rolling. Then they have shown you that they mean business. They will want you to show them the same respect in return.
Also, if pricing is more than they can afford, they won’t be wasting your time.
