Why: the goal or problem

Imagine a tool that exports a slide package for download. Once delivered, a recurring charge is hard to justify.

How: work toward a solution

A fictional slide exporter charges 30 in month one and zero in months two and three: total 30. The shared usage is 100, 300 and 600 exports. Here the license covers that example; taxes, fees and refunds are omitted. The timeline separates charges from usage.

One charge for a defined entitlement.

One-time payment

Slide exporter · first three months: 100 / 300 / 600 exports

  1. Month 130Exports: 100
  2. Month 20Exports: 300
  3. Month 30Exports: 600

Total: 30 + 0 + 0 = 30

This license covers the illustrated usage. Support, upgrades and hosted-service duration need separate terms.

Fictional amounts. Taxes, fees and refunds omitted.

The customer pays 30 in month one and zero in months two and three despite 100, 300 and 600 exports. Access follows the example’s license; the product seller still owes whatever support the offer promises.

What: the concept

One-time payment charges once for a specified purchase. The entitlement must separately define access, support and upgrades; one payment does not promise a lifetime hosted service.

Compare recurring billing when continued service creates ongoing costs.
