"Cost-plus" pricing: calculate your costs, add a margin, and charge that. It's logical. It's also leaving significant money on the table.
Cost-plus pricing is based on your inputs, not on customer value. A plumber who fixes a burst pipe in 20 minutes saved the customer $10,000 in water damage. Charging "20 minutes × hourly rate" misses the entire value delivered.
The alternative: price based on the value your service delivers to the customer.
Framework:
A landscaper switching from hourly billing ($65/hr × 4hrs = $260) to "weekly maintained curb appeal" packages ($395/month) — same work, $680+ more revenue per customer per month.
When you offer a single price, the only question is "buy or don't buy?" When you offer three tiers, the question becomes "which one?"
Basic ($X): Core service, essential deliverables, no extras
Standard ($X × 2.5): Core service + 2-3 valuable additions, most popular
Premium ($X × 5): Everything + VIP experience, white glove, fastest delivery
60-70% of customers choose the middle option when all three are explained equally. Design your most profitable offering to be the "Standard" tier.
