Charge for what scales with the customer, and make the unit obvious

The metric you bill on shapes everything downstream: how fairly the price tracks value, how predictable your revenue is, and how a buyer feels when the invoice grows. Choose it badly and every renewal is a fight. Choose it well and your revenue grows quietly alongside your customer without anyone having to renegotiate.

The best value metric rises with the value the customer receives. If they get more out of the product as they add seats, bill on seats. If the value is in the volume they process, bill on volume. The test is simple: when the customer's invoice goes up, do they also feel they are getting more? If yes, the metric is aligned. If the bill climbs while the value stays flat, you have built resentment into the model.

Beware metrics that punish success or feel arbitrary. Billing on something the customer cannot predict or control turns every month into anxiety, and anxious customers churn. A metric a buyer can look at and immediately understand ("we pay per active user, that makes sense") beats a clever one they have to model in a spreadsheet to forecast.

There is a real tension between pure usage pricing and flat predictable pricing. Usage tracks value beautifully but makes budgets unpredictable, which procurement hates. A flat platform fee is easy to forecast but decouples price from value. The pattern that resolves this for most B2B products is a committed base plus usage above it: a predictable floor the buyer can budget, and expansion that captures growth. You get predictability, they get fairness, and the model scales.
