So here's my rule: The rule of 80%. For anyone selling on an incremental basis, set your break points that the per-unit costs of the new tier are 80% of the per-unit cost for the previous tier.
In just the last week, two different people have come to me to get feedback on their pricing. One was a startup selling a very sophisticated product to corporate enterprises. The other was selling consulting services to individuals, small businesses, and trade associations. In both cases, however, the questions were the same: how should I price this on a per-head basis? When should I charge a flat fee? How do I make sure I'm not leaving money on the table? How do I make sure I'm not losing customers?An exploration of the Basecamp Account (Upgrade/Billing) Screen
