Trade-offs

  • Widget needs styling to match a premium theme

What "Free to install" actually means

This is the label to read carefully. It almost always means billing tied to your volume — a share of attributed revenue, or charges above an order threshold. The bill scales exactly as your store grows, so model it at twelve months of projected orders rather than today's.

Whatever the label says, the calculation is the same: a bundle app has to lift revenue by more than it costs. Our break-even calculator works out the lift you would need against your own orders and margin — for most stores it is a fraction of a percent, which means the subscription is rarely the real question. The payload the app adds to every page load usually is.
